Audiokit: Module compiled with Swift 5.0.1 cannot be imported by the Swift 5.1 compiler

[DaveWoodCom]

Unable to import AudioKit into an Xcode 11 project when using the vendored_frameworks in CocoaPods.

Xcode 11 gives the following error:

Module compiled with Swift 5.0.1 cannot be imported by the Swift 5.1 compiler: /Users/<snipped>/Pods/AudioKit/iOS/AudioKit.framework/Modules/AudioKit.swiftmodule/x86_64.swiftmodule

I assume the supplied framework needs to be rebuilt using the Xcode 11 GM?

Xcode Version: Xcode 11 (11A419c)

Correct. As a temporary workaround I'd remove the static Frameworks and just drop in the AudioKit for iOS xcodeproj into your project (make sure to set it as a dependency / "link with binaries" in your app)

[megastep]

It's weird that I've had no issues linking with the 4.8 pod in Xcode 11 GM. In any case, we should probably push out 4.8.1 built with Xcode 11 at some point soon...

[sieren]

Oh yeah, might be different when working with the Pods.. In that case xcode-select -s /Applications/Xcode.app may do the trick (in case you run multiple Xcode versions @DaveWoodCom )

[megastep]

I don't think it really matters because the root of this issue is our pod uses pre-built binaries (still on Xcode 10 at this point). The Swift ABI was supposed to be stable finally so in theory you'd think they would link with any subsequent version of Xcode, but it was definitely broken during the beta period.

[DaveWoodCom]

Yes, this is just because of the pre-built binaries built with Xcode 10.

Swift ABI stability only applies to run-time, doesn't apply to compile time. See the blog post about it here: https://swift.org/blog/abi-stability-and-more/#module-stability

I'm seeing this issue, too. I can't build AudioKit under Xcode 11 GM due to this error, when installed using Cocoapods.

[smarchant-owlet]

@aure @DaveWoodCom Do you know what the timeline is for issuing a release that fixes this issue? This will probably become a bigger issue next week, once Xcode 11 rolls out as the final public version.

[aure]

As soon as possible!

[benpackard]

Would be great to know if anyone has a workaround for Cocoapods users in the meantime. We have a non-AudioKit iOS 13 bug that we are blocked from working on at the moment since we can't compile on Xcode ~13~ 11.

[aure]

Man, we have our hands full just with Xcode11, never mind 13. ;)

[benpackard]

Lol oops.

[megastep]

Version 4.9 was just pushed out, including a pod built with Xcode 11 GM 2.

[aboelbisher]

Hi
did any one found a fix (workaround) for this ?

[sieren]

Did you update your Podfile to 4.9?

[markjeschke]

@aboelbisher, the mistake that I made, was having Xcode's command line tools _pointing to the Xcode 10.3 version, instead of Xcode 11._ After updating its path with sudo xcode-select -switch /Applications/Xcode.app, I was finally able to pod update to AudioKit 4.9. Prior to that change, I was only able to install AudioKit 4.7.1, which isn't compatible with Xcode 11 (hence the "Module compiled with Swift 5.0.1 cannot be imported by the Swift 5.1 compiler" error).

Don't forget to run pod update. Please let us know if this helps.

@DaveWoodCom I was facing the same issue for that I have updated my local copy of Swift as well you can do that in XCode's Preferences under Location ->

[markjeschke]

Ah, nice shortcut, @DaveWoodCom!

[jeremycochoy]

Could we have a 4.8 (.1) build compatible with XCode 11?

[aure]

You can make one if you want.

[jeremycochoy]

Thanks for the offer. Since I do not have enough time to look at the whole packaging process I simply used directly the 4.8 iOS project file as documented in the readme and mentioned by @sieren .

[coreyackland]

Anyone have an update for this? I've tried using the latest release of AudioKit and also tried implementing it via Cocoa pods, nothing works for me. Xcode Version 11.2 (11B52)

Downloading and embedded an older version of AudioKit works, however the latest doesn't. Just wondering if there is an update or if a fix is coming soon?

[aure]

@coreyackland Works for me, possible that you have a cached copy of AudioKit somewhere. Its really weird that an old version of AUdioKit would work. Which one? how old? like v2? :)

[coreyackland]

Ok so downloading directly from the website, AudioKit 4.9 is pulled (which is where I was having issues). Downloading from https://github.com/audiokit/AudioKit/releases, with version 4.9.2 works.

[aure]

Oh thank you, I forgot to update the web site. Fixed now.
