UITableViewCell auto height based on amount of UILabel text

Use UITableViewAutomaticDimension

tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 300

To go a little further on Dao's answer..

He is correct, you need to use UITableViewAutomaticDimension

Also, you need to ensure that you setup your constraints in a way that all of the content in the cell is constrained to the cells contentView. So your label will likely need constraints such as

• Leading constraint to ImageView
• Top constraint to contentView
• Bottom constraint to contentView
• Trailing constraint to contentView

Make sure that you set the UILabel to multiline (or lines = 0) and it should work.

If you are using the heightForRowAt delegate functions ensure you return UITableViewAutomaticDimension
