I try to integrate Fabric/Crashlytics via CocoaPods, my Podfile looks like this:
pod \'Fabric/Core\', \'1.2\'
pod \'Fabric/Crashlytics\', \'1.2\'
I have meet this issue before. Here is my solution. to add the execution mode for the run file automatically before your run the script.
In the Build Phase -> Run Script
add following line:
chmod +x ./Pods/CrashlyticsFramework/Crashlytics.framework/run
./Pods/CrashlyticsFramework/Crashlytics.framework/run YOUR_API_KEY YOUR_BUILD_SECRET
