I have a Swift Package with shared code.
With Xcode's SPM added to my Xcode project.
Works great in the main app.
Doesn't work in the helper app when exported. Running the helper app in Xcode itself works fine. But when running as an exported and signed app it doesn't work.
This error message was found in console:
Fatal error: unable to find bundle named MySwiftPackageName: file MySwiftPackageName/resource_bundle_accessor.swift, line 27
I double checked, the package is really added at
Build Phase -> Link Binary With Libraries
When I inspect the exported main app and helper app I found the package in the main resources folder but not in the helper app resources folder.
How can I fix this?
In the Swift Package Manager the use of Bundle changes a bit, when you compile the source or open up Xcode a autogenerated code is available to you, which is Bundle.module.
The Bundle.module code is fairly simple and should resolve the issue, it is used like this.
SwiftUI
Image("ImageName", bundle: Bundle.module)
UIKit
UIImage(named: "ImageName", in: .module, with: nil)
I am building the static iOS framework upon multiple libraries in Xcode. One of them should be the card.io. I cannot use cocoapods or carthage. So far I imported .frameworks within the .framework and it works pretty well. However card.io uses static library (.a file) with bunch of headers. It works well in dynamic type of .frameworks (or iOS app project) but in static project I get these errors on including of the .a files:
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't locate file for: -lCardIO
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: -lCardIO is not an object file (not allowed in a library)
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't locate file for: -lopencv_core
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: -lopencv_core is not an object file (not allowed in a library)
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: can't locate file for: -lopencv_imgproc
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file: -lopencv_imgproc is not an object file (not allowed in a library)
Regarding these errors I downloaded the source codes of card.io and it looks that there is dynamic .framework target waiting for build. I tried to use this one instead of .a files and headers - so my project at least can be builded. Because the card.io does not contatin architectures for simulator (which, by the way, it should with this release 5.2.2) I am not able to test it in unit tests, so when I test this solution on device I get this error:
dyld: Library not loaded: #rpath/CardIO.framework/CardIO
Referenced from: /var/containers/Bundle/Application/55D3AF7F-83F4-4B3D-A667-0FCO93CCC441/App/AppDemo
Reason: no suitable image found.
So far my knowledge+google+stackoverflow is stuck here, because it looks that xcode does not support the .framework within .framework this way.
To this moment I spent two days with this "issue", so the question is: Does exist any solution for including dynamic library into static framework? Or any solution to include card.io into static framework?
EDIT:
Well actually the solution was more stupid than I would think (as always). Just to include card.io in the .framework go to "Project Description -> Build Settings -> Library search paths" and type the path where should xcode look for the libraries. This approach solves the first one issue of this post - this means the implementation of the .a libraries and headers.
At this moment I cannot guarantee it will work in releases based on my framework so I will update this post to confirm it later. I hope it helps someone...
I'm trying to build a command-line tool which uses sqlite. I have downloaded Stephen Celis' swift wrapper, SQLite.swift, and built a working OS X app. However, I am not able to build my command-line tool. I believe that I correctly followed the instructions to do so in the SQLite.swift Documentation for frameworkless targets, but apparently I am missing something. I get an error in Helper.swift # import CSQLite -> No such module 'CSQLite'.
I am linking against libsqlite3.dylib (also tried libsqlite3.tbd)
I added the SQLite.swift source to my project
I added #import sqlite3.h & #import "SQLite-Bridging.h" to my bridging header file. Perhaps of note, when I right-click on sqlite3.h or SQLite-Bridging.h, xCode does not know where/what they are.
I'm happy to send my test project (about 80KB, compressed) to anyone who can and is willing to help. There is probably a very simple solution, I just do not see what it is.
thx for any help,

I've faced the same problem.
There were lots of compiler errors like "Connection.swift:26:8: Could not build Objective-C module 'CSQLite'"
The error has roots to the "lctx.h:13:25: Use of undeclared identifier 'SYS_getlcid'"
It worth mentioning that I have two Xcodes installed - v 6.2 at /Applications and v 7.3 at ~/Applications. My project is iOS app on Swift with SQLite pod and I open it with the Xcode 7.3.
The SQLite pod has a file at project_folder/Pods/SQLite.swift/CocoaPods/iphonesimulator/module.modulemap.
The file had the content
module CSQLite [system] {
header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/sqlite3.h"
export *
}
To fix compiler errors I changed the content of module.modulemap to
module CSQLite [system] {
header "/Users/my_user_name/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/sqlite3.h"
export *
}
The change is that I pointed search of sqlite3.h into my ~/Applications folder where Xcode 7.3 is located.
This made my project compiling.
I have a Xamarin.Forms project which needs a QR code scanner. I found ZXing Scanner which seems to be a well established library for such purposes.
I installed it in the corresponding android project which worked without errors. When I wanted to build the app, Resource.Designer.cs was adjusted with the following lines:
global::ZXing.Mobile.Resource.Id.contentFrame = global::my.project.Droid.Resource.Id.contentFrame;
global::ZXing.Mobile.Resource.Layout.zxingscanneractivitylayout = global::my.project.Droid.Resource.Layout.zxingscanneractivitylayout;
global::ZXing.Mobile.Resource.Layout.zxingscannerfragmentlayout = global::my.project.Droid.Resource.Layout.zxingscannerfragmentlayout;
The problem is that I as well get the following errors:
'my.project.Droid.Resource.Id' does not contain a definition for 'contentFrame'
'my.project.Droid.Resource.Layout' does not contain a definition for 'zxingscanneractivitylayout'
'my.project.Droid.Resource.Layout' does not contain a definition for 'zxingscannerfragmentlayout'
I installed ZXing using NuGet but I as well tried to add the dlls manually. I get the same errors. Can anyone help me how to fix this?
Thank you in advance.
It's quite possible that your Resource.Designer.cs is not updating correctly:
Clean Project Build
Remove ZXing package.
Clean Project Build
Add ZXing package
Clean and Build Project once again

I have a framework written in obj-c and swift.
Now i try to run a related unit test target, but I get this error:

Any idea what the root cause can be?
The error seems realated to "Library not loaded: #rpath/libswiftAppKit.dylib"
Both (framework and test bundle) compile without any error or warning (in Beta2)
I had a similar problem, though mine was an iOS test target, linking to a Swift framework, that failed to run on Xcode 6 GM. The test target had run successfully on an early beta of Xcode 6, but the final version reported the runtime error: Library not loaded: #rpath/libswiftCore.dylib
I noticed that a newer project did not have the failure, so I compared the build settings and test code. I was able to resolve the problem with three steps:
The test target needs the "Embedded Target Contains Swift Code" setting to be YES. This tells the linker to add the Swift runtime libraries to the executable.
The test target needs an explicit value for the "Runpath Search Paths" build setting. This tells the loader where to find the Swift runtime libaries. I copied the following setting from a fresh new test target:
LD_RUNPATH_SEARCH_PATHS = $(inherited) #executable_path/../Frameworks #loader_path/../Frameworks
The test cases need to explicitly import any modules that are used by the linked framework. In my project, the framework used UIKit but the test cases only used my framework. When I added an explicit import UIKit to the test cases, the link problem went away.
Since I keep running into this issue whenever I mess with build settings, here's the cleanest answer I can provide as of Xcode 8b5:
If unit tests don't run on iOS, make sure you have:
Runpath Search Paths: #loader_path/Frameworks
If unit tests don't run on macOS, make sure you have:
Runpath Search Paths: #loader_path/../Frameworks
This will show up as LD_RUNPATH_SEARCH_PATHS in your pbxproj file. You can also add $(inherited) to make sure project-wide paths are added as well, but those are probably empty.
Lastly, I didn't need the executable_path/... settings, doesn't make a difference for me whether they're there or not for unit tests.
I had the same problem.
Ended up copying libswiftAppKit.dylib out of the Xcode application directory (I am using beta 3), into a directory that I could reference (not part of an application bundle), then adding the library to the "Link binary with libraries" setting for the test bundle. My tests then started working.
FYI, the path for the dylib was at '/Applications/Xcode6-Beta3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libswiftAppKit.dylib'
Probably not a good final solution, but it works for the interim.
My solution was to add a single file to my test target, AppKitTests.swift (or AppKitSpec.swift in my case), and all the file contains is:
// While I don't know why, The.framework is built linked to libswiftAppKit.
// Frameworks do not embed the Swift libraries themselves, it's up to the host
// app to include the necessary libraries. So here we are, including AppKit on
// behalf of The.framework so that the tests can run.
import AppKit
Oh, I also added AppKit to the test target's set of frameworks.
I had this occur to me in Beta 4 and it turned out that I had done it to myself without realizing it.
I had a Framework project called Fnord. My FnordTests target contained a couple of unit test classes that had import Fnord at the top of each file. For some reason Xcode was complaining about those imports and so I commented them out. This is when I started getting the same symptoms while trying to run my unit tests.
I noticed that the settings for my FnordTests target were such that the target would be linked with Fnord.framework, and I realized that it might not be able to do that with the aforementioned import Fnord statements diked-out.
So I put them back in, and everything went back to normal. Curiously, Xcode no longer showed those import statements as being problematic, but this is beta so I can forgive that.
I hope this helps someone.
I ran into the same issue, adding
import AppKit
in the Swift file fixed it
