Added Fabric/Crashlytics to new project but doesn't upload dSYM
Go to Build settings and choose Dwarf with dSym File option for both debug and release builds.
You haven't uploaded dsym ..You can get dsym file from:
Goto https://itunesconnect.apple.com> SignUp> MyApps> Activity> Then select the version of App for which the Missing dsym error is showing and download the dsym file from there...
upload it to fabric
Hope so your issue is resolved..
