Xcode does not install the apps on the device

Dear: Since I updated the iPad operating system to the iPadOS 15.3.1 version that I use for development, when I try to load the applications, to test them, a message appears from Xcode saying:

“Unable to install…(+ the name of the application)

and the app won’t load.

I’m using a MacMini late 2012. 16 Gb of Ram
You have MacOS Catalina version 10.15.7

I can’t update the operating system with this hardware.
And I can’t install a newer version of Xcode either.

Xcode version 12.4
Corona Simulator Version 2022.3665 (2022.2.23)

If understand your problem correctly you have a few options:

  1. Buy a machine that can run at least 11.6. You can easily buy or swap the mac mini for one. I am currently using a late 2013 MacBook Pro. These can easily be had for under $200 on Ebay.
  2. Buy an iPhone or iPad with a lower version of iOS.
  3. Send the build to TestFlight and test that way.

These are the only options I can think of.
