I have a UITableViewController with a set of static UITableViewCells with some dynamic content, but after upgrading to XCode 7, the cells are not resizing anymore, and the content overlaps the cells below. I noticed the following 'rect' tags are added to the storyboard.
<rect key="frame" x="8" y="8" width="584" height="584"/>
The content inside the cell, is a UIImageView with a 1:1 ratio constraints, so that it always stick to the sides and is resized in height.
Constraints for the UITableViewCell.
<tableViewCell userInteractionEnabled="NO" contentMode="scaleToFill" selectionStyle="none" indentationWidth="10" id="TeM-3R-AKy">
                                    <rect key="frame" x="0.0" y="124" width="600" height="44"/>
                                    <autoresizingMask key="autoresizingMask"/>
                                    <tableViewCellContentView key="contentView" opaque="NO" clipsSubviews="YES" multipleTouchEnabled="YES" contentMode="center" tableViewCell="TeM-3R-AKy" id="Ul9-Ad-TSI">
