Compile with Xcode 12 Apple Swift version 5.3

[mattiriihimaki]

I'm getting an error while trying to compile my project.

Failed to build module 'PhraseSDK' from its module interface; the compiler that produced it, 'Apple Swift version 5.2.4 (swiftlang-1103.0.32.9 clang-1103.0.32.53)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3 (swiftlang-1200.0.29.2 clang-1200.0.30.1)'

Hello @mattiriihimaki,

I just re-verfied the SDK 2.3.1 pod to be working with Xcode 12 on iOS 13.5 and 14.0. Could you please provide more details about your setup? Are you using Carthage by any chance?

The above error should not happen, as the SDK is compiled with "Build library for distribution" (a.k.a. Module Stability). Iirc Carthage has known issues with Xcode 12 so that's probably something you are running into? Could you try using CocoaPods 1.9.3?

I'm using the CocoaPod 1.9.3 and 2.3.1 PhraseSDK

Build to a device or to "Any iOS Device" works but building for a simulator fails.

"unable to load standard library for target 'arm64-apple-ios9.0'"

@mattiriihimaki The error is very likely related to your project file and CocoaPods way of linking framework architectures. As to my knowledge Xcode never had any ARM64 simulator, but the simulator is always x86_64 (but there are Simulators with ARM64 for Apple Silicon now). So the reference to the standard library arm64-apple-ios9.0 is never right for the iOS 9.0 Simulator.

Please see https://stackoverflow.com/questions/63342162/cannot-build-project-with-xcode-12-0-beta-5 for the same error with the previous Xcode beta 5.

When I ran into this myself I had to remove the VALID_ARCHS from the project build settings, run pod deintegrate and pod install together with cleaning derived data afterwards and doing a clean build.

If this does not help: What macOS Version are you using? There are known issues with the current Big Sur Beta related to Xcode 12.

Yea, I was able to fix the problem with this https://stackoverflow.com/questions/63607158/xcode-12-building-for-ios-simulator-but-linking-in-object-file-built-for-ios. So, this had nothing to do with your SDK. Sorry and thank you for the help :)

@mattiriihimaki You're welcome and thank you for your feedback! I am glad to hear that I was able to point in the right direction. No problem, sometimes it' s difficult to find out where problems have their origins. Especially with Xcode 12 😅

👋 While the solution @mattiriihimaki linked gets things working, it doesn't seem like an ideal long term solution since it won't allow simulator builds to run on an M1 mac. Do you have ideas for a solution beside excluding arm_64 simulator archs from the podspec?

Hi @scannillo,

the mentioned workaround is not be necessary anymore, a fully M1/arm64 compatible release was published in January 2021. Just install the latest version e.g. via CocoaPods (please update CocoaPods itself too), SwiftPM or the see latest releases https://github.com/phrase/ios-sdk/releases when installing manually.

Feel free to open a new issue if you have any issues or troubles getting this working.

Hope that helps!
