iOS8 - constraints ambiguously suggest a height of zero

Question

Has anyone got any idea how to debug this?

Warning once only: Detected a case where constraints ambiguously suggest a height of zero for a tableview c

Answer 1

In Swift forcing a return height fixed my problem:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    if(indexPath.row == 0){
       return CGFloat(131.0)
    }else if(indexPath.row == 8){
       return CGFloat(97.0)
    }else{
       return CGFloat(44.0)
    }
}
