title: Handling private frameworks in Xcode ≥ 7.3
body: <p><a href="https://developer.apple.com/library/ios/releasenotes/DeveloperTools/RN-Xcode/Chapters/Introduction.html">With Xcode 7.3 / iOS 9.3 Apple removed all private frameworks</a> from the iOS SDKs. For research purposes (not App Store!) I need to work with a private framework (namely <code>BluetoothManager.framework</code>, but this is also an issue for any other <strong>private</strong> frameworks). </p>
  
  <p>Because these frameworks are no longer delivered in the iOS SDKs, I get a build (linker) error if my project attempts to link to this framework explicitly.</p>
  
  <p>Any ideas for a long(er)-term solution?</p>
