Having this problem as well (Xcode 14.3 iOS 16.4). The problem only happens with MapAnnotation. Using MapMarker causes the purple warnings to go away. Another option to suppress the warnings is to use a constant value for the map's coordinateRegion binding. Not possible if you actually need the value but thought I'd post it here anyways. E.g., Use Map( coordinateRegion: .constant(mapRegion), // <-- use .constant(mapRegion) instead of $mapRegion annotationItems: items, ...

I'm having the same issue. It seems related to the same warning with the older API which is discussed here: https://developer.apple.com/forums/thread/718697 What is interesting is that if you use the old API on Xcode 15 beta 1 the warning goes away but if you use the new API it comes back :(
