OSX - QtCreator ignoring kit compiler

[Luca_nam]

Hi,
I have an old application that need to be compiled with an old XCode.app version.
I installed xcode on path /applications/xcode_12_5_1.app

Then I created a kit on Qt Creator config to use the old compiler as you can see on the image:

The problem is that when building it always use default /applications/xcode.app completely ignoring the kit config.

Where do I wrong ?

Thanks
Luca

@Luca_nam And you did set this compiler in the Kit you're using?

@jsulm

yes, the compiler is set in the Kit.

The only way to use my xcode_12_5_1.app is to change default system xcode by executing

xcode-select -s /Applications/Xcode_12_5_1.app/Contents/Developer
