Hi -
I'm blocked by a spurious error in XCode I can't shake, in an iOS/Catalyst app project in swift with swift packages.
The target has an iOS deployment version of 14.1, but XCode UI behaves like the target is set to 13.0:
The package product 'LIB' requires minimum platform version 14.0 for the iOS platform, but this target supports 13.0
The command line builds fine:
xcodebuild -configuration Release -scheme 'Study (iOS)' # (also Debug config)
I'm sure I must be missing some configuration, but I have set the iOS/catalyst deployment version > 14 in project and target.
To confirm:
- I'm using the same target scheme in XCode UI as the command-line build
- I fail in the UI using any relevant target devices (i.e., over iOS 14, mac catalyst or ipad)
- The project selector clearly shows target 14.1 (project/Deployment target/iOS deployment target)
- The project/target UI clearly shows deployment target 14.1 (project view, 'Study (iOS)' target, iOS Deployment Target)
- Same result when using version 15.0 instead of 14.1
- Same result when disabling catalyst support and targeting iPad
- Same result with or without a derived mac catalyst product bundle identifier
- Same result for macOS targets 11..12.4
- 14.0 = macOS 11.0
- 15.0 = 12.0
- Same result after creating a new run scheme.
- Scanning all files in the project confirms these settings and does not show a relevant 13
- e.g., in "IPHONEOS_DEPLOYMENT_TARGET[sdk=macosx*]" and
IPHONEOS_DEPLOYMENT_TARGET
- e.g., in "IPHONEOS_DEPLOYMENT_TARGET[sdk=macosx*]" and
- I'm running macOS 12.4, XCode 13.4 (13F17a), default 5.6 toolchain, with packages declaring 5.6 toolchain
- No external xcconfig files
- In the XCode UI, I've done clean builds and reset the package cache
- I've deleted XCode's Derived Data and restarted mac
- I'm also developing packages (and have cleaned .build and .swiftpm directories) but app package dependencies are pulling from remote repository (i.e., not using local packages)
So:
Any clue as to why XCode believes the target is 13 and not 14.1?
How I can debug this?
Is there some way XCode can indicate the target triplet and SDK and how it is derived?
Is the next step to recreate the project?
Thanks!
Oy! Just as I was giving up, I solved it. In case it helps others...
The problem was an intermediate library targeting iOS 13. The XCode error was confusing.
Scenario:
- MyCoreLib swift package targeted iOS 14
- MyUILib swift package targeted iOS 13 (and used MyCoreLib)
- MyApp targeted iOS 14, and used both MyCoreLib and MyUILib
When building MyApp, the error said:
The package product 'MyCoreLib' requires minimum platform version 14.0 for the iOS platform, but this target supports 13.0
I could not find iOS-13 referenced anywhere in MyApp or MyCoreLib.
So I guess I should make a feedback assistant feature request to clarify that error message.
It should indicate the target triplet/SDK and how it was derived. (In this case it took the minimum of the imported packages).
