Invalid Swift Support / invalid implementation of swift

ios xcode swift app-store-connect

I'd like to upload an app written in swift. Application loader delivers the app successfully, but after a few minutes I get a reply by apple telling:

Invalid Swift Support - The bundle contains an invalid implementation of Swift. The app may have been built or signed with non-compliant or pre-release tools. Visit developer.apple.com for more information.

I use xCode Version 6.0.1 (6A317), Swift iOS SDK 8.0 and just build the app with xcode.

Where can I find any information on how to get a valid implementation of swift? Apple does not say anything concrete.

Thx

I had a similar problem. To fix it and be able to push a build to iTunesConnect I had to do the following:

  • Set the flag EMBEDDED_CONTENT_CONTAINS_SWIFT to YES in the target settings
  • Be sure that Build Phases did not include any other weird targets
  • Logout all Apple Developper accounts from Xcode and login with just the one you want to push the app with.
  • Archive and submit the app with Xcode and NOT with Application Loader.

Why did I need to logout from all of my Apple Developper accounts?

Because Xcode does not know which account to use to upload the binary. Application Loader ask you in the beginning but then, the uploaded build isn't valid...

UPDATE:

Since Xcode 7.1 and the new versions of Swift I got the error again. The current workaround is to do the following:

  • Create an archive locally on Xcode (does not work on my CI)
  • On Organizer, export it as an AppStore build.
  • Use Application Loader to upload the binary.

After few minutes (~10) the build should be available on iTunesConnect.
