CI Build Error: ld: symbol(s) not found for architecture arm64

[cjam]

I'm building my app using Azure Devops and upgraded to 0.1.1 which subsequently broke the build with the following error:

❌  ld: symbol(s) not found for architecture arm64

❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

I think it might be related to me moving around some of the files within the Spotify.framework folder. Not sure how to test locally at this point, so I may have to push a new version.

Seems I'm not the only one seeing this.

spotify/ios-sdk#179

Oddly, it only seems to be on the CI build which is happening in azure devops. I can't reproduce it on my own machine.

This error is a result of using a framework that has been built in XCode 11 with the ___isPlatformVersionAtLeast check within a build running in XCode 10. According to this thread https://forums.developer.apple.com/thread/123003 XCode 11 injects some symbols that aren't available in XCode 10 and therefore breaks things.

Switched my CI environment to XCode 11 and it fixed the problem.
