});
} error:nil];when the third line is run i get error

  • Terminating app due to uncaught exception ‘NSRangeException’, reason: ‘* -[__NSArray0 objectAtIndex:]: index 3 beyond bounds for empty NSArray’ *** First throw call stack: (0x181245900 0x1808b3f80 0x1811c1478 0x10034d250 0x100318f24 0x1000ea9b0 0x101859bf0 0x101859bb0 0x10185f658 0x1811fcbb0 0x1811faa18 0x181129680 0x182638088 0x185fa0d90 0x10017d650 0x180cca8b8) libc++abi.dylib: terminating with uncaught exception of type NSException

Could you try adding the error block and see if you get a fault object in there? If you do, check the error message in the fault.

Do you have Backendless.initApp anywhere in your app?

No, i run this code in application: didFinishLaunchingWithOptions:, so before this method i didn’t have any lines of code.

I see. Please see the “Application Setup” section on this page:
