I am having the same issues, the Migrator seemingly isn't being called. Single app WatchKit that I just ported from WatchKit to widgetKit, running under watchOS 10

I am migrating a WatchKit complication that I support back to WatchOS 6.0 to WidgetKit. How do I support ClockKit in WatchOS prior to 9.0 and WidgetKit in 9.0 and newer? I can't seem to get my WidgetKit Extension to compile is I have WatchOS support earlier than 9.0. The compiler complains that things like "Timeline" doesn't exist prior to WatchOS 9.0, and I don't know how to conditional that since it is a runtime decision. (can't if #available around a class definition.) I'm sure it is something simple I am missing.

An no sooner did I type the question did I find the answer. I need to set BaseSDK and supportedPlatforms to WatchOS under BuildSettings which allowed me to set Deployment Target to 9.0 under General.

It seems to be related to .buttonStyle() Basically, there is a light gray overlay in the button style, if you are darker than that, you can see it bleed through. My solution was to creat a new buttonStyle, but that seems like an awfully obtuse approach just to change a color or corner radius. What am I missing?
