React-native-track-player: [ios] Swift is not supported for static libraries

[anderslemke]

After linking, I get this error when trying to build in XCode:

Can I fix this somehow?

[jasongrishkoff]

Hey @anderslemke -- it actually requires Xcode beta for Swift right now. Are you able to install that?

[anderslemke]

Oh! I will try... :)

[dcvz]

@anderslemke as Jason said, you'll need the latest Xcode 9 beta for this to work :)

[anderslemke]

Now I've updated, and that first error went away.
I have new one now, though... :)

ld: library not found for -lswiftCoreAudio for architecture x86_64

I will investigate.

I tried this: https://stackoverflow.com/a/39630099/923539

But it doesn't work...

[dcvz]

Hey @anderslemke are you working with a default xcode project? The ones generated by the react-native cli?

[anderslemke]

I would say so. It was, however, not generated with the latest version of React Native.

[dcvz]

Can you try adding a swift file to your project? You can call it dummy.swift then you will be prompted if you want to generate a bridging header. Say yes, and then try building again :)

We've yet to formalize the documentation for this.

[anderslemke]

Yes! I created the dummy.swift.
XCode failed, and gave me the path to the header file it was missing. So I created that file:

touch /Users/anders/Projects/zetland/lyd-react-native/ios/LydReactNative-Bridging-Header.h

Now it works! 🎉
