Interesting! I've recently plumped for UIKit (with bits of SwiftUI dropped in) for a new mapping app because, as you say, SwiftUI map support is virtually non-existent. Have you thought about adding Maplibre support as an alternative to MapKit?
replyI try to use MapKit, when possible, as it is unencumbered by licensing and support issues (and works pretty well), but I have considered MapBox. It’s commercial, but pretty straightforward, with licensing and support. I have heard good things about it.
replyI don’t really know about Maplibre (but I’ll check it out).
Had a friend create an app, based on Google Maps (if you remember, in Ye Days of Yore, GM was the mapping engine for iOS), but Google did the licensing rug-pull thing, and he had to do an emergency open-heart surgery to his app.
That was a sobering lesson about relying on third-party dependencies.
[EDIT] Looking at your app, I’ll not be surprised, if you’re familiar with my friend’s app: EasyRoute
