Thanks for reply. After I setup here and there I found out that a class to auto height the table view header to fit a label was the problem. Next step is to find out what's wrong there but for now it's working. override func viewDidLayoutSubviews(){         super.viewDidLayoutSubviews()         sizeHeaderToFit()     }     func sizeHeaderToFit(){         guard let headerView = tableView.tableHeaderView else { return }         headerView.setNeedsLayout()         headerView.layoutIfNeeded()         let height = headerView.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize).height         var frame = headerView.frame         frame.size.height = height - 412         headerView.frame = frame         tableView.tableHeaderView = headerView     } Here the 412 stands for all items (height) in the header together except the textfield. The header was assigned to class "TableViewHeaderSinglePost" wich contains: class TableViewHeaderSinglePost: UIView {     @IBOutlet var postTextLabel:UILabel!     override func layoutSubviews() {         super.layoutSubviews()         postTextLabel.preferredMaxLayoutWidth = postTextLabel.bounds.width     } } If someone sees the problem please let me know ;-) Thanks so far for helping me! Kind regards
