I changed Base SDK from 10.9 to 10.10 in my app and it solved the problem. As I see crash occurs only on 10.10.3 and higher system version. If you want to crash TextEdit just change Base SDK to 10.9 or open TextEdit 1.9 or earlier version. Also someone already wrote radar http://openradar.appspot.com/20991953
