title: XCode - Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1
body: <p>Lately I've started to take up a course for learning swift to devolp iOS OS X and Watch OS apps. I'm taking this course on udacity. The first step is to download a project and put it in a folder on your desktop. I had to open the app and then run it, which should've worked. But not for me somehow. I hit run and the following error showed up (this is the complete error log):

  <p>Some poeple suggested that I should update my XCode but I already have. I currently have XCode 7.3! I'm quite new to this platform, that's also why I'm doing this course, so I don't really know what I have to do. Can someone please tell me what's going on here?</p>
