I\'ve recently started getting this error:
2015-03-23 11:35:48.902 run[60036:1047011] Crashlytics.framework/run 1.3.14
2015-03-23 11:35:48.911 run[60036:1047
The below solution worked for me ,i hope it will help you.
Goto build setting of your project then Search for debug information format in build setting and search for "Debug information format" then set "Debug information format" to "DWARF with dSYM file"

and make sure Generate debug symbol in build setting is set to Yes.
