I am using the new multi-column UISplitViewController. I have a tab bar controller set as the view controller when in compact mode. I have a view in compact mode which displays a UIDatePicker in the new .inline style. Two tableview cells segue to that date picker view. I go into the date picker view and get a date. The problem seems to happen when I change the month of the date picker. When I return from the date picker view and then go back in for another date, I get the following in my console.

[CompositionalLayout] Invalid absolute dimension, must be > 0.0. NOTE: This will be a hard-assert soon, please update your call site.

I have no idea what this is. My layout is good.

I have uploaded my project. The title of the report is 'CompositionalLayout] Invalid absolute dimension, must be > 0.0. (Xcode 12)'.

It doesn't happen when the .wheels style is used. But it does in .automatic and .inline.

It looks like this issue has gone away with the new beta version of Xcode 12. Thanks for looking into this.
