This is such a bad bug that is still not fixed as of Xcode 12.0.1!

Update: Also completely busted for Xcode 12.2 (Beta 2). This is such a ridiculous issue! This on top of the code signing and copying issues with binary targets make them completely unusable for production. Such a shame.

Same issue here! Quite a ridiculous bug. The very silly, no-good fix is to uncheck "Upload debug symbols..." when going through the upload flow, but no one really wants to do that!!!

Came here with the same question 😂

This is an embarrassing missing feature in SwiftUI.

Absolutely nuts that these have been buried in "Build Settings"

Yea, it's truly insane I can't download my own app from the Mac App Store so I can test it properly!
