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.
Check for true "run script only when installing" on Run Script
Elaborating Bruno's response, if you already have a script phase that you need to run all the time, create a new dedicated phase in order to avoid conflicts.
I removed Fabric and Crashlytics and added them back again from the beginning just like I were to install it the first time around. It worked.
