I don't believe it's possible today to access the icon and tint color of a MapFeature although this would be incredibly helpful in the app that I'm building presently as I'm storing places in SwiftData and would like to use the same icon and tint color when listing places in the app.
It would be awesome if this were possible in the next version of iOS, iPadOS visionOS etc., if not presently possible.
This is possible! MapFeature
has properties backgroundColor and image that you can use.
