Can't submit apps to AppStore: ERROR ITMS-90534: "Invalid Toolchain
If you're looking at this in November 2019, there's an obscure error in Xcode 11.2, which prevents uploading from that version to the App Store. You'll have to upgrade to Xcode 11.2.1, which is currently not available on the Mac App Store yet, but must be downloaded from the Developer Portal here: https://developer.apple.com/download/
The Xcode 11.2 Archive error log even states:
Edit:
Xcode 11.2.1 is now available on the AppStore:
I was having the same issue with Xcode 8.3 public version. I reinstall the Xcode and check it, but didn't work ...
Finally I found the issue , I have mistakenly selected Xcode 3.2-compatible in project format under project document. I changed it to Xcode 8.0-compatible and build & archived it. I could upload it without any errors. Check the screen shot attached ..
Xcode 11.2 is deprecated by Apple on November 5, 2019
