title: './build_frameworks.sh' fails with `xcodebuild: error: '../AudioKit.xcodeproj' does not exist.`
body: <p>First time installation of AudioKit with:</p>
  <p>-OS X 10.15.5 (19F101)
  -XCode Version 12.0.1 (12A7300)</p>
  <p>For other people's benefit: running ./build_frameworks.sh initially complained with:</p>
  <pre><code>xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
  </code></pre>
  <p>This seemed to be resolved after running:</p>
  <pre><code>sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
  </code></pre>
  <p>Running it again gave a slew of complains like this:</p>
  <pre><code>/Users/ali/Documents/Development/AudioKit: error: manifest parse error(s):

  <p>I see that the author addressed a similar question in <a href="https://stackoverflow.com/questions/46921133/why-does-running-build-frameworks-sh-fail">this Stack Overflow thread</a> but I am running the script from within the Frameworks folder so I don't think this is my issue....</p>
