As soon as I create an Xcode project I can't build and have a bunch of errors (Xcode version 12.4)
Could not build Objective-C module 'SwiftUI'
I figured it out! MY Xcode was using the wrong toolchain version even tho I tried to uninstall Xcode and reinstall it.
Make sure you have selected the correct version, in my case since I was running Xcode 12.4, I had to use version 12.4 for toolchains. It's weird that Xcode did not manually change it since I updated.
To updated version:
Xcode > Preferences > Components > Toolchains > and then select your
version

So I got an demo ios project from different company but I can't launch it
Basically i get two errors:
Sometimes I also go an unsupported swift architecure error
I work on M2 processor and use XCode 14.2
Project does not have pods, all packages are managed via spm (that's what I was told)
For now i tried:
opening xcode via rosetta (nothing changed)
changing version of xcode to 14.0 (nothing changed)
using other swift version via toolchain (Swift 5.7), screen below ( get different erorrs but i dont think its a good way)
UPDATE
I downloaded version 14.0 of xcode and toolchain 5.7.2
When i use that version of xcode i get an error about missing classes from that sdk in scope and also some weird error from SentrySamplingProvider ( screens below)
I'm using xCode 13.1 with macOS 12.0.1 Monterey. I added KingFisher and removed it from my pod. but my project is not built anymore. I got this error for one of my local SDKs:
Failed to build module 'CbSdk';
this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.4
(swiftlang-1205.0.26.9 clang-1205.0.19.55)', while this compiler is 'Apple Swift version 5.5.1
(swiftlang-1300.0.31.4 clang-1300.0.29.6)'). Please select a toolchain which matches the SDK.
What I've done but didn't work:
pod deintegrate and pod install.
restart xCode with clearing cache and DerivedData.
checkout old branch and commit that worked before.
moving code to another macBook that worked before.
download, install and select toolchain 5.4 (odd errors appeared -> )
changing swift compiler language of my target and project to swift 4 (It says you are using swift 5.5.1 again!)
note that I didn't update xcode or swift!

You need to set the BUILD_LIBRARY_FOR_DISTRIBUTION build setting on the framework target

I fetch the same problem when I try to update a library. My Xcode version was 13.2 with the swift version5.5.2. But the library I want to update required a swift version of 5.7.0. Using toolchains in Xcode might be the solution but I decided to update the Xcode version with the latest.
I update my Xcode to the latest version 14.1 and the issue is resolved. Automatically the swift version is found on the latest Xcode.
I upgraded to Flutter 2.5.0 and now I cannot run on an IOS simulator, from either Android Studio or the command line.
It fails with the error
Runner.xcodeproj: error: The linked framework 'Pods_Runner.framework' is missing one or more architectures
required by this target: arm64. (in target 'Runner' from project 'Runner')
I can manage to run on the Simulator from XCode without an issue
I can run on a device from Android Studio or command line
I have tried
restarting the simulator.
cleaning the build folder
upgrading Cocoapods to 1.11.1
Flutter Doctor says that everything is fine.
----------------- Edit ------------------
The situation Eventually Resolved Itself.
This is a problem because of ARM64 for me. This helped for me.
Be sure to open .xcworkspace.
Adding "arm64" to Project -> Build Settings -> Excluded Architecture
The reason why this might have been happened is because Xcode has been updated to a newer version. You gotta love Xcode..
Some time after upgrading to Xcode 9, I discovered that I was no longer able to build a Kitura-based project with the Swift 3.1.1 snapshot (which I have installed via swiftenv).
When I ran swift build, some time into the build I would get:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.apinotes:8:28: error: unknown key 'SwiftImportAsNonGeneric'
SwiftImportAsNonGeneric: true
^
<unknown>:0: error: could not build Objective-C module 'Foundation'
It seems that there is a dependency between Swift and Xcode, and Xcode 9 is no longer fully compatible with Swift 3.1.1 (or earlier) snapshots. I believe it may be because my project uses Foundation, and Foundation on Mac is provided as part of Xcode, whereas on Linux it is part of the Swift snapshot (via swift-corelibs-foundation).
I did find a solution to this problem: If I keep a copy of Xcode 8.3.3 around (eg. in /Applications/Xcode8.3.3.app) then I can use sudo xcode-select -s /Applications/Xcode<version>.app/Contents/Developer to select the appropriate one prior to building with SPM, and I can then build both Swift 3.1.1 and 4.0 projects on the same system.
However, this feels a bit clunky. Each time I build a project with the 'other' Swift version, I have to make sure I run xcode-select, or the build will fail. Is having multiple versions of Xcode the right solution in this case, or am I missing a trick with Xcode 9?
note that if, like me, you upgraded Xcode via the App Store, previous versions of Xcode are still available from https://developer.apple.com/download/more/
I'm running macOS 10.12.3 with Xcode 8.3.
I cannot build any macOS Swift projects with it.
If I create a new Cocoa application Xcode project and set it to use Swift, when I try to compile it, I immediately get the following error in the "check dependencies" phase:
error: There is no SDK with the name or path '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk'
I have no idea what's going wrong!
The only clue I have is that earlier I created a symlink with the path /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk that pointed to MacOSX.sdk in order to fix an issue where an older build of Qt that required an SDK with that path. However, deleting the symlink has no effect.
I can build Swift projects that targeting other platforms like iOS. Just not macOS.
Help!
try running this command then reopening the project
(Xcode uses xtools in the command line to build its projects)
sudo xcode-select -switch /path/to/file/
(by default the path is)/Applications/Xcode.app/
look at this pic
saw it here yesterday
