Removing the default ***.skybox file fixed the issue for me.

The minimal reproducible example:
import SwiftUI
import MapKit
extension CLLocationCoordinate2D: Identifiable, Hashable {
public static func == (lhs: CLLocationCoordinate2D, rhs: CLLocationCoordinate2D) -> Bool {
lhs.latitude == rhs.latitude && lhs.longitude == rhs.longitude
}
public func hash(into hasher: inout Hasher) {
hasher.combine(self.id)
}
public var id: String {
String(self.latitude) + " " + String(self.longitude)
}
}
struct MapKitIssuesView: View {
@State var coordinates: [CLLocationCoordinate2D] = []
@State var selectedCoord: CLLocationCoordinate2D?
var body: some View {
ZStack {
Map {
ForEach(coordinates, id: \.self) { coord in
let _ = print("reloaded \(coord) at \(Date())")
Annotation("", coordinate: coord) {
Circle()
.fill(.black)
.frame(width: 4, height: 4)
}
}
if let selectedCoord {
Annotation("", coordinate: selectedCoord) {
Circle()
.stroke(.orange, lineWidth: 4)
.fill(.white)
.frame(width: 16, height: 16)
}
} else {
EmptyMapContent()
}
}
.mapStyle(.standard(pointsOfInterest: .excludingAll))
.onAppear {
for lat in 30 ... 45 {
for lon in -137 ... -79 {
coordinates.append(.init(latitude: Double(lat), longitude: Double(lon)))
}
}
}
.onDisappear {
coordinates.removeAll()
}
VStack {
Spacer()
Button(action: {
selectedCoord = .init(latitude: .random(in: 30 ..< 45), longitude: .random(in: -137 ..< -79))
}, label: {
Text("Change Selection")
})
.tint(.white)
}
}
}
}
