This is mistake..

NSRangeException ', reason:' *** - [__ NSArrayM objectAtIndex:]: index 5 outside for an empty array '

Answer 1

Reason:. You are accessing an empty array that is trying to access the object in the index.

replace all places as in your code below

[arrMydata objectAtIndex:indexPath.row]; 

from

  //1. Positive index ([anArray objectAtIndex:-NUMBERS]) will crash //2. within the array boundary if([arrMydata count] > 0 && [arrMydata count] > indexPath.row){ shrObj=[arrMydata objectAtIndex:indexPath.row]; } else{ //Array is empty,handle as you needed } 

** Here you can see an example without software that will explain this problem. Good luck **

Answer 2

Your array is empty, but you are trying to access the object in it. This is problem.

Answer 3

Reason: According to your log, you are trying to access empty arrays. Just fix it below code

 if (arrMydata.count > inxexPath.row) sharObj = [arrMydata objectAtIndex:indexPath.row] 

Answer 4

In case this helps someone: in my case, the array was not in the code, but at the output of IB, which was an array of 5 UIImageViews in the storyboard.

@IBOutlet var upAndDownArrowImages: [UIImageView]!

The reason for the failure was that I mistakenly deleted 1 of these UIImageViews from the storyboard.
