title: This Code Signature is no longer supported when building app on iPhone 12
body: <p>The solution on the other post with a similar title: <a href="https://stackoverflow.com/questions/68467306/the-code-signature-version-is-no-longer-supported">The code signature version is no longer supported</a> DOES NOT WORK.</p>
  <p>I used to be able to install my app onto my phone. I have updated my phone and then I updated xCode so that I could install it to IOS 14.6, and now I get this code signature version is no longer supported error. It runs fine on the simulator but not on my phone.</p>
  <p>I get this error output:</p>
