title: Xcode doesn’t support iOS 15.0
body: <p>I updated my iPhone to iOS 15.0 yesterday and I wanted to build in Xcode (version 12.5.1).
  But in Xcode it is showing 'iPhone (unsupported OS version)' and when I try to build (command + R) then I get the error:</p>
  <blockquote>
  <p>Xcode doesn’t support iPhone’s iOS 15.0 (19A346).</p>
  </blockquote>
  <p>Is there a way to use it without downgrading iOS?</p>
