Not sure how to delete this post, but I have it fixed... Still is an Apple issue, but I don't care like explaining since nobody will understand. Has to do with synchronous/asynchronous nature of multi-threading... The fact that there is a difference between Xcode and TestFlight (presumably App Store Apps are using the same binaries as TestFlight), that really says something... There is something causing the code to be interpreted differently, and executed at different intervals (discrepancies between Xcode and TestFlight). That should never happen... I had to post like 10 versions to TestFlight to test, since the Xcode version was working for me each time... The TestFlight interpreter/compiler/builder/whatever it is needs the patch... the Xcode version is working as expected when it comes to order of execution (in my opinion).

Apple should really fix this... I think it has to do with the device files in this new version of Xcode... I'm so sick of having to delete the app and re-download all its data manually, and then having to reserve 5 times as much storage on my MacBook Pro as the 15GB size of Xcode. Look at all these recent comments of people who are just trying to develop something... PS - I'm developing on an XR right now...
