Answer 1

All you need is implement UITableView Delegate this way:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

override func tableView(tableView: UITableView, estimatedHeightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

By default, estimatedHeight is CGRectZero, when you set some value for it, it enables autoresizing (the same situation with UICollectionView), you can do even also so:

tableView?.estimatedRowHeight = CGSizeMake(50.f, 50.f); 

Then you need to setup you constraints inside your cell.
