Map Drag, Zoom, Rotate Freezes Map

[mkaulfers]

Describe the bug It seems that updating the map with any gesture causes the map to simply freeze, rather than panning and zooming. The same thing happens whenever I tap on an Annotation

To Reproduce Steps to reproduce the behavior:

1. Launch on Previews or Simulator at Map
2. Attempt to interact

Expected behavior It should allow gestures

Versions (please complete the following information):

• Running OS: iOS 16
• Xcode: 14.3
• Development OS: Ventura 13.4

Screenshots Shows loading the map, using the code below, and that I can't interact with it.

    @EnvironmentObject var appConfig: AppConfig

    @State var zoom: Double = 1.0
    @State var coordinates: LocationCoordinate
    @State var points: [Annotations]
    @State var isUserLocationVisible = false

    var body: some View {
        AnnotationMapView(
            zoom: $zoom, // Starting Zoom of Map (Range: 0-1, Lower is closer in)
            coordinates: $coordinates, // Starting address in the Center of the Map (use this or coordinates)
            points: $points,
            isUserLocationVisible: $isUserLocationVisible, // Binding for if isUserLocationVisible
            selected: { Title, Subtitle, Address, isCluster in // Action When Marker is Selected (Returns title, subtitle, and address in annotation along with if it's in a cluster)
                print("tapped \(Address)")
            }, deselected: { // Action When Marker is Deselceted
                print("deselected annotation")

        var totalLat = 0.0
        var totalLong = 0.0

        for poi in pois {
            totalLat += poi.coordinate.latitude
            totalLong += poi.coordinate.longitude
        }

        let avgLat = totalLat / Double(pois.count)
        let avgLong = totalLong / Double(pois.count)

        return MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: avgLat, longitude: avgLong), span: MKCoordinateSpan(latitudeDelta: 0.5, longitudeDelta: 0.5))
    }

Request

It's entirely possible that I have miffed the implementation completely, if so please let me know and I'll attempt to correct it. Also, is it possible to utilize a custom SwiftUI view in place of the Annotation?

Can you please provide a small sample project for me to debug and play around with?

@mkaulfers ?

[mkaulfers]

I'm trying to see if I can come up with something. It was a blocker for me so I ended up pulling the package from my project. In theory you should be able to reproduce by just passing in your own locations that have a coordinate property.

I think that it may have to do with the overlays

[mkaulfers]

Can you explain a bit more what you think it might be? I'll fork and take a gander. I've been trying to implement my own maps and yeh, it's a heavy lift, so having a working package would be better xD. Does this package also support routes and such.

@mkaulfers Sorry for not responding until now. I believe I found the issue and fixed it a couple months ago, but did you find resolution?
