Error While creating Custom Framework and xcframework - swift

I am creating a Framework where i am adding multiple Third Party Libraries manually. and creating a Fat framework SomeFrameworkName.framework using the script below
#!/bin/sh
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Step 1. Build Device and Simulator versions
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"
# Step 3. Copy Swift modules from iphonesimulator build (if it exists) to the copied framework directory
SIMULATOR_SWIFT_MODULES_DIR="${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/."
if [ -d "${SIMULATOR_SWIFT_MODULES_DIR}" ]; then
cp -R "${SIMULATOR_SWIFT_MODULES_DIR}" "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
fi
# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"
# Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"
# Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"
After Archiving i am able to get the framework file but when i try to add that framework into the demo project it gives me multiple errors as follows:
dyld: Library not loaded: #rpath/TestIOS.framework/TestIOS
Referenced from: /private/var/containers/Bundle/Application/E76B5EA8-2E7C-44A4-BDCC-A8AB0B37E500/TestAshishDemo.app/TestDemo

or else any library names comes in the picture.
and whenever i try to create the xcframework file i get the following error
Failed to build module from its module interface; it may have been damaged or it may have triggered a bug in the Swift compiler when it was produced
i am on a crucial stage to solve this error. Anyone if facing the same issue or faced the same along the way they created framework Please Help me out
XCode Version - 12.5.1

In your target project, did you try to embed the Framework ?

xcframework does not contain internal frameworks

I am trying to create an .xcframework file for a few third party libraries I'm using. Following the instructions from https://appspector.com/blog/xcframeworks, I
Create platform-specific framework files:
# Archive for device
xcodebuild archive -scheme TestFramework -destination="iOS" -archivePath /tmp/xcf/ios.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphoneos SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES
# Archive for simulator
xcodebuild archive -scheme TestFramework -destination="iOS Simulator" -archivePath /tmp/xcf/iossimulator.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphonesimulator SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES
At this point, I've gotten two frameworks with .swiftmodule files; everything looks good. The frameworks do not come with .swiftinterface files, but I think that is alright as these are objc projects. Then, I
Combine the individual frameworks to form a single xcframework file:
# Build xcframework with two archives
xcodebuild -create-xcframework -framework /tmp/xcf/ios.xcarchive/Products/Library/Frameworks/TestFramework.framework -framework /tmp/xcf/iossimulator.xcarchive/Products/Library/Frameworks/TestFramework.framework -output /tmp/xcf/TestFramework.xcframework
Here, xcodebuild doesn't fail, but it emits a curious error:
No 'swiftinterface' files found within '/Users/user/git/ReactiveObjC/output/xcf/ios.xcarchive/Products/Products/Library/TestFramework.framework/Modules/TestFramework.swiftmodule'.
Crucially, the .xcframework package does not contain the individual frameworks or folders specified in the Info.plist file. Obviously, when I try to link to the xcframework in this state, I get a bunch of "missing symbols" linker errors.
Why is this? What must I do to get xcodebuild to create the xcframework completely?
NB: Manually creating the folders seems to work for now, but this feels wrong and is brittle – Apple can change the way xcodebuild works anytime.
Turns out that adding BUILD_LIBRARY_FOR_DISTRIBUTION = YES to the end of the xcodebuild command was not enough / not working to produce a framework with the required swiftinterface files. I had to go in the settings for the actual project and manually set BUILD_LIBRARY_FOR_DISTRIBUTION to YES, like this answer suggests. After I got the frameworks with the swiftinterface files, I was then able to create the xcframework file using xcodebuild without any problems.
Create XCFramework
XCFramework replaces Fat/Universal framework. It is a bundle which contains multiple .framewok for each architecture/platform. We don't need to use lipo[About] for unite and separate frameworks manually
XCFramework supports libraries with headers and Objective-C
Enable Build Libraries for Distribution(BUILD_LIBRARY_FOR_DISTRIBUTION) for your framework. XCFramework works only with enabled [BUILD_LIBRARY_FOR_DISTRIBUTION]. If not when you run step 3 xcodebuild -create-xcframework you get (or don't)
No 'swiftinterface' files found within '<some_path>/<some_name>.xcarchive/Products/Library/Frameworks/<some_name>.framework/Modules/<some_name>.swiftmodule'
Build/archive .framework for different architectures/platforms
xcodebuild archive \
-workspace ModuleName.xcworkspace \
-scheme "schemaName" \
-sdk "iphoneos" \
-arch arm64 \
-archivePath "<some_path>/ArchiveName1.xcarchive" \
SKIP_INSTALL=NO \
xcodebuild archive \
-workspace ModuleName.xcworkspace \
-scheme "schemaName" \
-sdk "iphonesimulator" \
-arch x86_64 \
-archivePath "<some_path>/ArchiveName2.xcarchive" \
SKIP_INSTALL=NO \
SKIP_INSTALL[About] one of key point to include framework inside archive
Create XCFramework using xcodebuild -create-xcframework
xcodebuild -create-xcframework \
-framework "<some_path>/ArchiveName1.xcarchive/Products/Library/Frameworks/ModuleName.framework" \
-debug-symbols "<some_path>/ArchiveName1.xcarchive/dSYMs/${schemes[$n]}.ModuleName.dSYM" \
-framework "<some_path>/ArchiveName2.xcarchive/Products/Library/Frameworks/ModuleName.framework"
-debug-symbols allows to add .dSYM[About] and .BCSymbolMap[About]
Converting to XCFramework from Cocoapods
For my scenario, I'm trying to build XCFrameworks from the FAT/lipo frameworks generated by cocoapods.
I added this to the end of my podfile:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
end
end
end
This ensured the frameworks were compiled correctly and I was able to run the normal xcodebuild -create-xcframework ... command to generate the XCFramework.
Note: I'm also using the cocoapods-binary plugin to pre-build all the pods frameworks.
I faced the same issue. It turned out that Xcode 13's build settings override the SKIP_INSTALL=NO flag in the command line. Once I set this field in project's build setting to NO (and made sure on the way that the Build Library For Distribution is set to YES) I managed to create the xcframework file successfully.
I have added readme file with full details how to create xc framework.
https://github.com/awasthi027/Xcode_lib_framework_issues/blob/master/README.md

Xcode 10: Code Signing my App+Framework fails, because of failure signing 3rd party dependency framework (PromiseKit). Works in Xcode 9

I have an Xcode 10 - iOS12 swift project that links against My own framework (also Xcode 10 + iOS12).
The app project is referencing my framework project as a sub-project reference.
My Framework project references PromiseKit.framework (a universal framework - fat library), made using the following build script:
# Merge Script
# 1
# Set bash script to exit immediately if any commands fail.
set -e
# 2
# Setup some constants for use later on.
FRAMEWORK_NAME="PromiseKit"
# 3
# If remnants from a previous build exist, delete them.
if [ -d "${SRCROOT}/build" ]; then
rm -rf "${SRCROOT}/build"
fi
# 4
# Build the framework for device and for simulator (using
# all needed architectures).
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch arm64 only_active_arch=no defines_module=yes -sdk "iphoneos"
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch x86_64 only_active_arch=no defines_module=yes -sdk "iphonesimulator"
# 5
# Remove .framework file if exists on Desktop from previous run.
if [ -d "${SRCROOT}/${FRAMEWORK_NAME}.framework" ]; then
rm -rf "${SRCROOT}/${FRAMEWORK_NAME}.framework"
fi
# 6
# Copy the device version of framework to Desktop.
cp -r "${SRCROOT}/build/Release-iphoneos/${FRAMEWORK_NAME}.framework" "${SRCROOT}/${FRAMEWORK_NAME}.framework"
# 7
# Replace the framework executable within the framework with
# a new version created by merging the device and simulator
# frameworks' executables with lipo.
lipo -create -output "${SRCROOT}/${FRAMEWORK_NAME}.framework/${FRAMEWORK_NAME}" "${SRCROOT}/build/Release-iphoneos/${FRAMEWORK_NAME}.framework/${FRAMEWORK_NAME}" "${SRCROOT}/build/Release-iphonesimulator/${FRAMEWORK_NAME}.framework/${FRAMEWORK_NAME}"
# 8
# Copy the Swift module mappings for the simulator into the
# framework. The device mappings already exist from step 6.
cp -r "${SRCROOT}/build/Release-iphonesimulator/${FRAMEWORK_NAME}.framework/Modules/${FRAMEWORK_NAME}.swiftmodule/" "${SRCROOT}/${FRAMEWORK_NAME}.framework/Modules/${FRAMEWORK_NAME}.swiftmodule"
# 9
# Delete the most recent build.
if [ -d "${SRCROOT}/build" ]; then
rm -rf "${SRCROOT}/build"
fi
When I go to archive my Parent App Project using Xcode 10 (And also 9.4.1) with Bitcode ON (that contains My Framework reference, and PromiseKit Fat library), I get the following error on the Signing stage: (Failed to verify bitcode in PromiseKit.framework/PromiseKit: error Cannot extract bundle from /var/folders..../(x86_64) - which suggests that it's simulator slice related)
If I turn the "Rebuild from Bitcode" option in the Organizer to OFF, then I get a different error: (Code signing "PromiseKit.framework" failed)
However, if I use Xcode 9.4.1 With Bitcode OFF, then it exports and signs fine.
Why is it trying to individually re-sign sub frameworks, and what can I do to alleviate the issues? I need the archiving to work normally with Xcode 10, along with any future third party dependencies being added to my framework target. (This is the first dynamic framework dependency added to my Framework target. Before I was "baking in" - in-boarding all 3rd parties for ease of development purposes, but PromiseKit is difficult to inboard due to extensive dependencies on Objective-c).
The Xcode Archive log is:
{
code = 330;
description = "Failed to resolve linkage dependency PromiseKit x86_64 -> #rpath/libswiftFoundation.dylib: Unknown arch x86_64";
info = {
};
level = WARN;
},
{
code = 330;
description = "Failed to resolve linkage dependency PromiseKit x86_64 -> #rpath/libswiftObjectiveC.dylib: Unknown arch x86_64";
info = {
};
level = WARN;
},
{
code = 0;
description = "Failed to verify bitcode in PromiseKit.framework/PromiseKit:\nerror: Cannot extract bundle from /var/folders/q5/hm9v_6x53lj0gj02yxqtkmd40000gn/T/IDEDistributionOptionThinning.RJD/Payload/MyAppName.app/Frameworks/PromiseKit.framework/PromiseKit (x86_64)\n\n";
info = {
};
level = ERROR;
type = "malformed-payload";
}
);
Some other solutions I tried was using a Project Reference to PromiseKit, instead of a Framework reference, however this doesn't work - in that I still need a framework reference from my main project, because I will get "library not loaded" error at runtime, if running without a FW reference. Same issue occurs when archiving while using a project reference.
Try this! It worked for me and many other people:
Goto
Build phases > Add > New Run Script Phase
The code should work for any default shell, but I recommend just using /bin/sh
and include the following code:
# Type a script or drag a script file from your workspace to insert its path.
# skip if we run in debug
if [ "$CONFIGURATION" == "Debug" ]; then
echo "Skip frameworks cleaning in debug version"
exit 0
fi
APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"
EXTRACTED_ARCHS=()
for ARCH in $ARCHS
do
echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
done
echo "Merging extracted architectures: ${ARCHS}"
lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[#]}"
rm "${EXTRACTED_ARCHS[#]}"
echo "Replacing original executable with thinned version"
rm "$FRAMEWORK_EXECUTABLE_PATH"
mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"
done
It seems hat some frameworks ship architectures, that will not be used in the application.
Xcode will refuse to sign them. The above script removes unused architectures.
Credits: Some guy at GitHub, I can't find the exact source anymore.
Same issue here. The only workaround I've found is to use static library instead of framework.
In case you are not able to use static library, you'd better file a bug report to Apple.
This is what worked for me,
I have application and 2 in-house built frameworks, say A $ B.
Application needs A, but A needs B and since Apple doesn't recommend nesting frameworks, so both A and B had to be included in the app.
This is what my Xcode project looks like.
SOLUTION
In the application, under Frameworks, Libraries and Embedded Content, select Embed & Sign for all necessary frameworks. (as shown below)
But for all the custom framework projects, under Frameworks and Libraries section, select Do Not Embed. (as shown below)
This fixed the issue for me

Swift private Framework with backward xcode version compatibility

This is my first framework using Swift language and it's private framework. It's worked as expected until new Xcode 9.3 release. After upgrading newer Xcode got an issue like this Module compiled with Swift 4.0.3 cannot be imported in Swift 4.1.
After that only I realized framework doesn't support auto version (Xcode/Swift) upgrade, Did some search found there is a Universal or Fat Binary Framework single build instead of separate build for real device and simulator which I missed in previously.
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
# Make sure the output directory exists
mkdir -p "${UNIVERSAL_OUTPUTFOLDER}"
# Next, work out if we're in SIM or DEVICE
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
# Step 2. Copy the framework structure (from iphoneos build) to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"
# Step 3. Copy Swift modules from iphonesimulator build (if it exists) to the copied framework directory
BUILD_PRODUCTS="${SYMROOT}/../../../../Products"
cp -R "${BUILD_PRODUCTS}/Debug-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/." "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
# Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_PRODUCTS}/Debug-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"
# Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"
# Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"

At Edit Scheme -> Archive -> Post-Action -> Run Script
This time I am used Swift Compiler - Language -> Swift 3.3
And I got expected output this time too in Xcode 9.3 with Swift 4.1
When I try to run the project with this framework at Xcode 9.2 it's show error like this
Module compiled with Swift 4.1 cannot be imported in Swift 3.2.3:
Try to resolve with backward compatibility and I didn't find. How can I run this framework in Xcode 9.2
Framework support: Swift and Objective C, Min OS iOS 8.0
**Update**
Also got something like this error
compiled with newer version of Swift language (unknown ABI version 0x06) than previous files (4.0) file 'MAC location' for architecture armv7
And tried this to my project

Swift fat framework w/Objective-C Cocoapod

I've built a framework in Swift. The framework uses Cocoapods, one of the pods is written in Objective C.
I also use a custom script to make the framework a fat framework so it supports 32/64 bit systems. (This runs in a separate target on the project and I'm wondering if that has something to do with it?)
UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal
if [ "true" == ${ALREADYINVOKED:-false} ]
then
echo "RECURSION: Detected, stopping"
else
export ALREADYINVOKED="true"
// Step 1. Build Device and Simulator versions
xcodebuild -target "${PROJECT_NAME}" ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
xcodebuild -target "${PROJECT_NAME}" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
//Step 2. Copy the framework structure (from iphoneos build) to the universal folder
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework" "${UNIVERSAL_OUTPUTFOLDER}/"
// Step 3. Copy Swift modules (from iphonesimulator build) to the copied framework directory
cp -R "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule/." "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/Modules/${PROJECT_NAME}.swiftmodule"
// Step 4. Create universal binary file using lipo and place the combined executable in the copied framework directory
lipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphonesimulator/${PROJECT_NAME}.framework/${PROJECT_NAME}" "${BUILD_DIR}/${CONFIGURATION}-iphoneos/${PROJECT_NAME}.framework/${PROJECT_NAME}"
// Step 5. Convenience step to copy the framework to the project's directory
cp -R "${UNIVERSAL_OUTPUTFOLDER}/${PROJECT_NAME}.framework" "${PROJECT_DIR}"
// Step 6. Convenience step to open the project's directory in Finder
open "${PROJECT_DIR}"
fi
When I create this fat framework and put it into a project I'd like to use it on the compiler always fails b/c the project can't see the objective C cocoa pod module.
clang: error: linker command failed with exit code 1 (use -v to see invocation)
ld: framework not found Pusher for architecture x86_64
It is not found for any architecture when I change the build platform.
Any solution where I can produce a framework that I can use in a separate Xcode project (for all iOS or OS X) would be awesome.
You can't run xcodebuild with -target when using CocoaPods. When you use -target, Xcode will only consider the active project and fail to pull in the Pod dependencies, similar to if you just opened the project file in Xcode and tried building.
You should be running xcodebuild -workspace "${PROJECT_NAME}.xcworkspace" -scheme "${PROJECT_NAME}" ..., assuming that CocoaPods generated the workspace and Xcode generated a scheme using the target name. You will also need to make sure your scheme is marked as shared if running this on another device.
Once your framework is built you will need to include it and the frameworks it depends on in apps that will be using it. For your framework, that means including it in General > Embedded Binaries and General > Linked Frameworks and Libraries. For frameworks you depend on, (e.g. AlamoFire), you could instruct users to include it in their Podfile, you could package it and ship it along with your framework, or you could do both and let the user do what works for them.
Apparently you are missing the 64bit architecture for Simulator.
When you build a target from Xcode, depending on what kind of simulator you have selected - the produced library will contains i386 or x86_64 respectively for selected 32bit or 64bit version of the simulator.
I guess that the cli build is producing only i386 version.
You can try to set the architectures in the script:
xcodebuild -target "${PROJECT_NAME}" ARCHS="i386 x86_64" -configuration ${CONFIGURATION} -sdk iphonesimulator ONLY_ACTIVE_ARCH=NO BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" clean build
As an alternative You can try to build by hand using 64bit simulator (iPhone 5S +), then extract the missing architecture and then put it into the final library using lipo command.

(iphone) build xcode4 project from command line

I've used to build my project with
xcodebuild -proj MyProject.xcodeproj -target MyTarget - configuration Debug -sdk iphonesimulator4.3
this works(it builds fine) but when I hit run in xcode, it recompiles.
(with xcode3, there was no need to rebuild once I build using command line)
I suspect xcode build use workspace/scheme rather than project/target.
How do I find out the workspace name that my current xcode project is using?
Thank you
edit
Chetan's links gave me directions what to look for.
xcode4 stores build output in ~/Library/...
whereas xcodebuild -project .. saves build output in project's build directory.
(if you want the workspace capability, you can't use the build directory for build output)
I created a workspace containing my project and ran
xcodebuild -workspace myWorkSpace -scheme myScheme
this saves build output in ~/Library/...../Debug-iphoneos
whereas xcode4 run button from the same workspace and same scheme saves output in
~/Library/..../Debug-iphonesimulator
any guess on why xcodebuild command uses Debug-iphoneos? :(
edit2
xcodebuild -workspace myWorkSpace -scheme myScheme -sdk iphonesimulator4.3
specifying sdk solved it
I know it isn't strictly the answer to your question, but you can configure the output directory of your build using the CONFIGURATION_BUILD_DIR environment variable.
