Losing my mind over "ITMS-90426: Invalid Swift Support"

Hey There,
I'm trying to build a project on github, so I can get it working in testflight.
The project can be found here:
https://github.com/coderjoris/StructureScannerSwift

I've downloaded it, added icons and all that good stuff and now I'm trying to archive and upload it.

I can't seem to find out how to modify the project so it will submit successfully, I keep getting an email follow up with:

ITMS-90426: Invalid Swift Support - The SwiftSupport folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.

My submission steps are as follows:
  • clean the build folder

  • Product > Archive

  • Then I follow the prompts to upload to the app store.

Trying to fix the issue, I've tried every single recommendation I can find on the internet, and nothing seems to fix it. Some examples:
  • updated OS and Xcode to their most recent versions

  • toggled "Always Embed Swift Standard Libraries" between Yes/No for both project and target

  • tried using the deprecated build system to build

  • etc..

Does anyone have any ideas about what might be causing this? I feel like I'm going crazy and I've run out of google search results to provide leads.



I ended up giving up on this completely for a while and just working on some features in the mean time.

I took a chance and just tried the submission process again though. This time it worked with no SwiftSupport error.

During the development I added a SwiftUI component and had to add some swift files in the process. I wonder if doing this flipped a switch somewhere and fixed the issue.

I don't have time to research this now but before I merge my branch I'll try to determine what ended up fixing the issue.
