title: XCode code siging error XCTest
body: <p>When I try to run my application on a simulator, everything works fine. But when I try to build it to test it on a real device, I get the following error:</p>
  
  <pre><code>CodeSign /Users/fvoordeckers/Library/Developer/Xcode/DerivedData/MyProject-##########/Build/Products/Debug-iphoneos/MyProject.xctest

  <p>I've changed IDs with <code>#</code>. I created a provisioning profile that includes the device I'm using and al the required certificates. It doesn't seem to have a problem with the app but with the xctest... I also tried adding the '--deep' flag to the signing configuration but it didn't help...</p>
