Swift Fatal Error

I keep getting this error code.

fatal error: Cannot index empty buffer

and Xcode says that the problem is here,

cell.textLabel?.text = self.taskMgr.completedTasks[indexPath.row].taskName

I check the docs and I didn't get anything useful out of it, I also checked in the dark bowls of the internet and I couldn't find anything.

Thank You.

Have you checked if the "completedTask" array/list is empty? From what i can se from the web the error message: "fatal error: Cannot index empty buffer" is described as if you where to fetch a item from an empty array/list

This can be easily fixed with (if of type array):

if (self.taskMgr.completedTasks.count > 0) {
      cell.textLabel?.text = self.taskMgr.completedTasks[indexPath.row].taskName
}
