title: compilation error when porting AudioKit iOS app to Catalyst macOS app
body: <p>I have an iOS app that has been working fine with AudioKit's iOS build.  I wanted to try porting to macOS w Catalyst by dropping in AudioKit.xcframework.  Here is what I did</p>
  
  <ol>
  <li>compile AudioKit-4.9.5 from source to generate AudioKit.xcframework (I had previously been using a locally compiled AudioKit iOS framework from the same source release with no issues on the non-Catalyst version)</li>
  <li>in the "General" tab,
  
  <ul>
  <li>checked Mac as a deployment target</li>
  <li>removed the old AudioKit iOS framework</li>
  <li>added AudioKit.xcframework</li>
  </ul></li>
  <li>in "Build Settings" tab,
  
  <ul>
  <li>change "Framework Search Paths" from the parent directory of the AudioKit iOS framework to the parent directory of AudioKit.xcframework</li>
  </ul></li>
  <li>in the "Build Phases" tab,
  
  <ul>
  <li>AudioKit.xcframework appears in "Link Binary with Libraries"</li>
  <li>AudioKit.xcframework appears in "Embed Frameworks"</li>
  </ul></li>
  </ol>
  
  <p>I receive the following errors,</p>
