quaternaryLabel is a property defined on UIColor not Color, so you must have an extension linking the two together.

This no longer works in iOS 16. From the iOS & iPadOS 16 Beta Release Notes: The implementation of list no longer uses UITableView . (81571203)

For me, this is also fixed. Let's just hope this is true for everyone.

Having just watched the video, Jacob does add the property called room. You just have to continue watching after the bit where your screenshot was taken (up to around 11:53).

I submitted a new report (FB9469285) with an attached previews diagnostics report.

Download Xcode 13 beta 4 from the downloads page, or wait until the official release some time in September.

Thank you for the help. I will definitely have a go at aligning the labels as you described. I did also submit a feedback report: FB9352737.
