Thanks Ashley I downloaded Xcode v.12 and the simulator is working fine!
However now I have a new problem with the v.12, I can't open a new project exported from Construct. I still can open the previous ones that were already open with the previous version but when I click on "Open" and choose the a decompressed exported zip file, Xcode close (or freeze)..
How can I fix that?
My export routine is:
Project export>IOS(Cordova)>Mini simple>Version 12.0+ / Construction IOS Xcode Project / hide status bar>Export>Decompression of the zip file>Open Xcode>On the popup window, choose "Open a project or file">Select the decompressed file>Crash..
