title: Xcode 13 iOS 15 Programmatic Obj-C Constraints translatesAutoresizingMaskIntoConstraints
body: <p>I use 100% programmatic constraints in my interface code.  Upgraded to Xcode 13 and iOS 15.  Got tons of NEW execution warnings about constraints, all saying that the system had to break some constraints to comply with others.  I had not seen such warnings for several years, and have not touched my constraint code in all that time.  Yet thorough testing shows my code continues to run correctly.  What's up?</p>
