title: Xcode- 7: No such file or directory
body: <p>I keep trying to run my Xcode project (titled "YidKit") and it keeps giving me the following error: 
  <code>error: /Users/Dani/Library/Developer/Xcode/DerivedData/YidKit-exnbjyxkgkbeaedoznkmtoenfijq/Build/Products/Debug-iphoneos/YidKitTests.xctest: No such file or directory</code>. I spent several hours online, trying different solutions that I've seen, and nothing has worked. This is driving me crazy, because it is the only error left and I just finished getting rid of about 80 that were caused by Swift 2.0. I appreciate all of the help I can get!</p>
  
  <p><strong>UPDATE</strong>
  Here is an image of the file in the explorer. The red one is the file that is giving me the error.</p>
