Onesignal-ios-sdk: Mac Catalyst - Swift Project - Unable to load standard library for target 'x86_64h-apple-ios13.1-macabi'

[robertveringa89]

Description:

(your description here)

Environment

1. What version of the iOS SDK are you using?

• 2.12.6

1. How did you add the SDK to your project (eg. cocoapods)

• CocoaPods

Steps to Reproduce Issue:

Added Mac Catalyst support with checking the checkbox for the Target

Followed instructions of adding 'x86_64h' as discussed here: https://onesignal.com/blog/onesignal-supports-mac-catalyst-build/

When setting the build target to my MacBook Pro I get the follow error: Unable to load standard library for target 'x86_64h-apple-ios13.1-macabi'

Anything else:
If I set the build target to my iPad or to a simulator everything works fine.

Same problem for us. @robertveringa89 which version of Xcode are you using? I'm trying 11.2.1

[robertveringa89]

I'm at Version 11.3.1 (11C504). Build target is iOS 11.0

[exevil]

Same here.

[jkasten2]

Can you make sure you only have x86_64h without x86_64 for both "Valid Architectures" and "Architectures"?

More details in https://github.com/OneSignal/OneSignal-iOS-SDK/issues/534#issuecomment-563431891

[robertveringa89]

Yes, I did that for both

[exevil]

I tried multiple times with different configurations as well.

[marvin-yorke]

I've even tried leaving x86_64h the only architecture

ARCHS=x86_64h
VALID_ARCHS=x86_64h

[jkasten2]

I was able to reproduce the issue with Xcode 11.3.1 on a Swift project.
Objective-C projects build without this error.

I believe the x86_64h-apple-ios13.1-macabi standard library is referring to the Swift standard library. I tried to search if there is a x86_64h build of the swift standard library for Mac Catalyst but wasn't able to find anything. It is possible there is only a x86_64 build of this.

For reference here is the details of the exact error and the command it is running:
Error: <unknown>:0: error: unable to load standard library for target 'x86_64h-apple-ios13.1-macabi'

Workaround

Option 1 - Use Swift x86_64 for x86_64h builds

It might be possible to use the x86_64 build of Swift libraries for x86_64h, however we don't have the details on how or if this could be done. However it might be worth exploring.

Option 2 - Build OneSignal-iOS-SDK locally with x86_64

Currently the x86_64 archeature is being used for the iOS simulator, the simulator could be switch to use Mac Catalyst instead. To do this the ARCHS and VALID_ARCHS can be set to x86_64 on this line
https://github.com/OneSignal/OneSignal-iOS-SDK/blob/2.12.6/iOS_SDK/OneSignalSDK/build_fat_framework.sh#L19
To build on your machine you will also need to update these 2 lines to /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild
https://github.com/OneSignal/OneSignal-iOS-SDK/blob/2.12.6/iOS_SDK/OneSignalSDK/build_fat_framework.sh#L12-L13
Lastly delete simulator references from this line
https://github.com/OneSignal/OneSignal-iOS-SDK/blob/2.12.6/iOS_SDK/OneSignalSDK/build_fat_framework.sh#L40
Then you can run this script to create the OneSignal.framework file.

Fix

The long term fix will be for OneSignal to migrate from a static framework to an XCFramework.
https://developer.apple.com/videos/play/wwdc2019/416/
These should be able to support the same CPU architecture for multiple targets.

[SwiftiSwift]

How can I build the OneSignal-iOS-SDK locally ? I'm using Cocoapods currently

[emawby]

This issue is fixed by using the XCFramework version of the SDK (currently only supported via Cocoapods). Instructions for use are here

[SwiftiSwift]

@emawby It doesn't work. If i use the XCFramework of the SDK i get this error:

Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_OneSignal", referenced from: objc-class-ref in NotificationService.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is my Podfile:

target 'MY_PROJECT_NAME' do

  pod 'FSPagerView'
  pod 'Firebase/Analytics'
  pod 'Firebase/Crashlytics'
  pod 'Firebase/Performance'
  pod 'OneSignalXCFramework', :git => 'https://github.com/OneSignal/OneSignal-iOS-SDK.git', :tag => '2.15.1'

end

target 'OneSignalNotificationServiceExtension' do
  #only copy below line
  pod 'OneSignalXCFramework', :git => 'https://github.com/OneSignal/OneSignal-iOS-SDK.git', :tag => '2.15.1'
end

These are my Architectures for my_project target:

I get the SAME error when i use x86_64h for both 'Valid Architectures' and 'Architectures'

[emawby]

@SwiftiSwift Hello, this is a known Cocoapods bug that is fixed in their upcoming release (Cocoapods is only using one of the slices in the XCFramework). To get the fix now run sudo gem install cocoapods --pre and reinstall the XCFramework

[SwiftiSwift]

@emawby Then i get this error for 'MY_PROJECT Workspace':

Multiple commands produce '/Users/USER_NAME/Library/Developer/Xcode/DerivedData/PROJECT_NAME-aeazewmhqxgqogghbnuwewuaajan/Build/Products/Debug-iphonesimulator/XCFrameworkIntermediates/OneSignal':
1) That command depends on command in Target 'OneSignalXCFramework-iOS10.0' (project 'Pods'): script phase “[CP] Copy XCFrameworks”
2) That command depends on command in Target 'OneSignalXCFramework-iOS9.0' (project 'Pods'): script phase “[CP] Copy XCFrameworks”

pod deintegrate and pod install doesn't work either

@SwiftiSwift are you still encountering this error with the latest version of Cocoapods? I am not able to reproduce this issue.

[SwiftiSwift]

@emawby I still encounter this issue with the latest version 2.15.4!

[emawby]

@SwiftiSwift but are you on the latest version of cocoapods itself not the OneSignal pod?

[SwiftiSwift]

Yes I ran sudo gem install cocoapods --pre

[emawby]

What is your minimum deployment target? When I do this I do not have 2 targets in the Pod project I only have 1. Are you deploying to iOS 9?

[SwiftiSwift]

@emawby (Please @ me if you answer to me so i get an email notification.) My Minimum deployment target is iOS 9 for my project yes. For OneSignal it is iOS 10. These are my pods:

[SwiftiSwift]

@emawby any update?
