Description

Install Qt6.1.0 iOS binaries on macOS11.2(.3), open Creator and one of the examples, quickcontrols2/gallery used in test. Select iOS hw target (not the simulator) and compile.

Compile fails on linker error:

Full log attached.

I did another clean install, having 6.1.0, 6.0.4 and 5.15.4 iOS binaries installed. I compiled for reference also with 6.0.4 and 5.15.4 iOS binaries. Creator build failed in some cases, but when opening the xcodeproject file (created by Creator) in Xcode and compiled there, fails disappeared and when trying again with 6.1.0, it was able to build example as well as deploy and run on device also, with both Creator and Xcode. I don't know what I did to get it working, I was compiling different examples with one of the three Qt version.

But, after that, on same machine, I did again a fresh install only with 6.1.0 iOS, and again either Creator or Xcode was able to compile any of the examples I tried.

Simulator build works with 6.1.0. Also, RTA smoke tests run on 10.14, 10.15 and 11.0 on virtual machines work, but the use iOS Simulator mode.

I don't have macOS with older os to verify is this on 11.2 or others also.
