I'm trying to create a UIImage from a MKLookAroundScene, after the user has moved the scene, by looking (and moving) around. Is this possible? When I use MKLookAroundSnapshotter with the modified scene, I always get an image of the original (starting) scene. STEPS TO REPRODUCE Create a scene using MKLookAroundSceneRequest with coordinates. Use LookAroundPreview with a binding to MKLookAroundScene to get changes to the scene (based on looking around). User begins LookAround, moving the scene location and view. User ends LookAround The preview displays the updated scene properly. The scene's cameraFrameOverride values reflect the pitch, roll, yaw, and location changes. Pass the updated scene to MKLookAroundSnapshotter to get an image. Display the Image. The Image is the original scene (not what is displayed in the preview).

I am trying to use MapKit JS in Tauri and Flutter desktop apps but I can‘t because if I want the key not to expire I have to whitelist a domain but my apps don't run on the web and therefore don't have a valid domain.

I have a MKMapView with a MKScaleView. If I visualise a generic map I have the scale in km. When I change the MKMapRect using visibleMapRect, the scale doesn't change. If I use setVisibleMapRect(_ mapRect: MKMapRect, animated animate: Bool), the scale change but not to the correct one. For example, it shows a scale saying one inch corresponds to 250 m while it is 150 m. The same issue of I use MKCoordinateRegion. Instead, if I zoom in or zoom out pinching on the map, the scale updates correctly. Am I doing something wrong? How can I fix this? Sample code: import UIKit import MapKit let CORNER_RADIUS: CGFloat = 8.0 let METERS_PER_MILE: Double = 1609.344 class PIAnnotation: NSObject, MKAnnotation { var coordinate: CLLocationCoordinate2D private(set) var title: String? private(set) var subtitle: String? init(location: CLLocationCoordinate2D, title: String? = nil, subtitle: String? = nil) { coordinate = location self.title = title self.subtitle = subtitle } } class PISimpleMapView: MKMapView { private let HALF_MAP_SIDE_MULTIPLIER: Double = 1.4 private let pinIdentifier = "pinIdentifier" private var scaleView: MKScaleView? typealias PinAnnotationView = MKMarkerAnnotationView // MKPinAnnotationView required init?(coder: NSCoder) { super.init(coder: coder) inizialize() } override init(frame: CGRect) { super.init(frame: frame) inizialize() } func inizialize() { layer.cornerRadius = CORNER_RADIUS register(PinAnnotationView.self, forAnnotationViewWithReuseIdentifier: pinIdentifier) addScale() } private func addScale() { let scale = MKScaleView(mapView: self) scale.translatesAutoresizingMaskIntoConstraints = false scale.scaleVisibility = .visible // always visible addSubview(scale) let guide = safeAreaLayoutGuide NSLayoutConstraint.activate([ scale.leftAnchor.constraint(equalTo: guide.leftAnchor, constant: 16.0), scale.rightAnchor.constraint(equalTo: guide.centerXAnchor), scale.topAnchor.constraint(equalTo: guide.topAnchor), scale.heightAnchor.constraint(equalToConstant: 20.0) ]) scaleView?.removeFromSuperview() scaleView = scale } func displayPinOnMap(location: CLLocation) { let annotation = PIAnnotation(location: location.coordinate, title: "Sample", subtitle: nil) addAnnotation(annotation) // Position the map so that all overlays and annotations are visible on screen. visibleMapRect = visibleArea(from: annotation) // setVisibleMapRect(visibleArea(from: annotation), animated: true) // region = MKCoordinateRegion(visibleArea(from: annotation)) } private func visibleArea(from annotation: PIAnnotation) -> MKMapRect { let annotationPoint = MKMapPoint(annotation.coordinate) return MKMapRect(x: annotationPoint.x - HALF_MAP_SIDE_MULTIPLIER * METERS_PER_MILE, y: annotationPoint.y - HALF_MAP_SIDE_MULTIPLIER * METERS_PER_MILE, width: HALF_MAP_SIDE_MULTIPLIER * 2.0 * METERS_PER_MILE, height: HALF_MAP_SIDE_MULTIPLIER * 2.0 * METERS_PER_MILE) } }

How to change the Type of Map to be Public Transport? I want to see a public transport map. Thanks

I've seen a lot of posts around the internet about getting coordinates from an address, but none about how to do the opposite. What I would like to do is allow a person to drop a pin and then programmatically look up the address closest to the pin. Like if I drop a pin inside a mall on the map I would like to capture the address to the mall. Does anyone know how this could be done?

Hi there! I am tying to add and select a map pin using view long press when the gesture is begin. However after adding and selecting the pin it got deselected immediately, my assumption that it's conflicting when the original map gesture and it's deselecting the pin on the map (like if a pin was selected and you click anywhere on the map to deselect it). Note that if I increase minimumPressDuration for the UILongPressGestureRecognizer it works fine, but I want the value at 0.5 so the pin is quickly added. here is the full code: import SwiftUI import MapKit struct ContentView: View { @State var selection: CustomMapSelection? @State private var longPressPosition: CGPoint = .zero @State private var pinCoordinate: CLLocationCoordinate2D? var body: some View { MapReader { proxy in Map(selection: $selection) { if let pinCoordinate { Marker("Custom Location", coordinate: pinCoordinate) .tag(CustomMapSelection(coordinate: pinCoordinate)) } } .gesture(LongPressGestureRecognizer(position: $longPressPosition)) .onChange(of: longPressPosition) { if let coordinate = proxy.convert(longPressPosition, from: .global) { pinCoordinate = coordinate selection = CustomMapSelection(coordinate: coordinate) } } } } } struct CustomMapSelection: Hashable { let latitude: Double let longitude: Double init(coordinate: CLLocationCoordinate2D) { latitude = coordinate.latitude longitude = coordinate.longitude } } struct LongPressGestureRecognizer: UIGestureRecognizerRepresentable { @Binding var position: CGPoint func makeCoordinator(converter: CoordinateSpaceConverter) -> Coordinator { Coordinator() } func makeUIGestureRecognizer(context: Context) -> UILongPressGestureRecognizer { let recognizer = UILongPressGestureRecognizer() recognizer.delegate = context.coordinator // if you make the minimumPressDuration above 2, it works fine and the selection doesn't cancel recognizer.minimumPressDuration = 0.5 return recognizer } func handleUIGestureRecognizerAction(_ recognizer: UILongPressGestureRecognizer, context: Context) { if recognizer.state == .began { let position = recognizer.location(in: recognizer.view) self.position = position } } class Coordinator: NSObject, UIGestureRecognizerDelegate { func gestureRecognizer( _ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer ) -> Bool { return true } } } #Preview { ContentView() }

My query might return 20,000 coordinates. Does MapKit JS try to load all the coordinates at once into the map or does it only load what’s in the viewport of the map if we were to load 20,000 annotations into the say something like “landmark data” const? We have 900,000 coordinates to load into Los Angeles and are planning how we will do this. Obviously we can’t load 900,000 coordinates at once without performance issues, but some query’s return 20,000 results. Can someone point me to some information about large datasets and MapKit js or let me know if it’s handled and already built in to not try to load that many locations at once?

Hi everyone, I’m exploring the idea of displaying a live 3D view of Google Maps in a Vision Pro app using SwiftUI and RealityKit. I want users to be able to interact with the map, including panning, zooming in and out, and exploring different areas in a fully immersive environment. Is this technically possible within the Vision Pro ecosystem? If so, what would be the recommended approach to implement this? If not, are there any alternative methods or platforms that could provide a similar experience? Thanks in advance for your insights! Best, Siddharth

On iOS 16 and below, the Apple logo is not displayed (Leagal labe is displayed). On iOS 17, both logo and legal are displayed. I have not specified layoutMergin for MKMapView. Map View attribute inspector has specified standard settings Why is only Apple Logo is not displayed ? Thank you

Has anyone found a thread-safe pattern that can extract results from completerDidUpdateResults(MKLocalSearchCompleter) in the MKLocalSearchCompleterDelegate ? I've downloaded the code sample from Interacting with nearby points of interest and notice the conformance throws multiple errors in Xcode 16 Beta 5 with Swift 6: extension SearchDataSource: MKLocalSearchCompleterDelegate { nonisolated func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) { Task { let suggestedCompletions = completer.results await resultStreamContinuation?.yield(suggestedCompletions) } } Error: Task-isolated value of type '() async -> ()' passed as a strongly transferred parameter; later accesses could race and Error: Sending 'suggestedCompletions' risks causing data races Is there another technique I can use to share state of suggestedCompletions outside of the delegate in the code sample?

I would like to be able to use AsyncImage inside of a SwiftUI Map Marker like this: Map(position: $cameraPosition) { Marker(coordinate: coord) { AsyncImage(url: url) } } But when I try to do this I get one of two outcomes. The first outcome I've seen is a crash like this: Thread 1: EXC_BAD_ACCESS (code=1, address=0x20) The second possible outcome I've seen is that the image doesn't load but just has a blank placeholder like this: I also tried creating a custom View that takes the url, downloads the data asynchronously, converts the data to a UIImage, sets the UIImage to a @State variable and then uses the Image(uiimage:) SwiftUI view but I got the same results. Has anyone else gotten something like this working?

I have a UIKit app with an MKMapview. In that mapview, I show icons on the location of Airfields. When zooming out to Europe (or USA for that matter), the whole map is covered with the annotations, so I want to only show these annotations when zoomed in beyond some level. How can that be achieved? I did find a way like this: class MapViewController: UIViewController { var isAtBigZoom = true { didSet { guard oldValue != isAtBigZoom else { return } for case let annot in mapView.annotations { mapView.view(for: annot)?.alpha = isAtBigZoom ? 1 : 0 } } } } extension MapViewController: MKMapViewDelegate { func mapView(_ mapView: MKMapView, regionWillChangeAnimated animated: Bool) { isAtBigZoom = mapView.region.span.latitudeDelta < self.airportThreshold } } But I have 2 problems with that: Seems like a lot of processing power It only takes effect after a pan. So I zoom beyond the limit, alpha has the 'old' value. Only after I pan, the alpha is suddenly represented in the MapView. Does anybody know a better solution?

I'm a bit unsure about whether there’s a limit on the number of requests when using MKLocalSearch from MapKit. For example, if I have a large user base and need to make 200 requests per minute at peak times, will MapKit be able to handle this? Will the user be throttled after a number of requests? If there is a limit, is it based on the user or developer account? Additionally, if there is a limit, is it per day? Can you clarify? Just to give you an idea, here is an example of the request we make: let searchRequest = MKLocalSearch.Request() searchRequest.naturalLanguageQuery = myQueryStringHere localSearch?.cancel() // cancel the previous call if it exists localSearch = MKLocalSearch(request: searchRequest) localSearch?.start { (response, error) in guard error == nil else { completion(.failure(.myError)) return } let mapSearchLocations = response?.mapItems completion(.success(mapSearchLocations)) } } I appreciate your help in advance.

Hello, It’s unclear to me if there is a limit of requests when using MKLocalSearch from MapKit. Let’s say I have a very large user base and will use 1000 requests per minute at peak times. Will MapKit support this? But if there is a limit, is it by user or by developer account? Also, if there is a limit, is it per day? Here is an example of the request we use. let searchRequest = MKLocalSearch.Request() searchRequest.naturalLanguageQuery = myQueryStringHere localSearch?.cancel() // cancel the previous call if it exists localSearch = MKLocalSearch(request: searchRequest) localSearch?.start { (response, error) in guard error == nil else { completion(.failure(.myError)) return } let mapSearchLocations = response?.mapItems completion(.success(mapSearchLocations)) } }

Hi, I'm writing because I've been trying to set the .standard map style to render as a globe on an iPhone 15 running iOS 17 when zoomed out similar to how it works in Apple Maps but can't find any resources on how to make that happen as every time it appears as a flat 2D map, much unlike the .hybrid and .satellite types. I found another thread on this forum a year ago where someone said .standard was bugged and couldn't become a globe, but I'm honestly quite surprised this issue hasn't been brought up more often.

Hi I save a track and I get an error the last point isn't the user location by adding the point to core data. Is core data to slow? can you help me? greeting Fabain

In the apple map of some areas, there will be a very realistic real-life 3D map. And now I want to call it through 3d in visionOS (like model3d). How can I call it? Note: What I ask for is not to have an effect similar to 3d on a flat screen like in iOS, but to display the USDZ model in visionOS.

Unrelated from this topic but coming from mapbox where everything had a mapbox_id i feel like some things like localities like "columbus, Ohio" should still have a place id but maybe the muid serves that purpose idk and just something i should account for. Lastly on my mind is how to manage rate limiting since im just giving the same mapbox js token to all the clients. Of course for server api I can manage my own system for rate limiting logged in users a bit easier but not sure about mapkit js though I can only dream my project is big enough i need to even worry about that lol.

Hi , I have following scenario where I feel performance issue. Use-case: I have multiple Overlays(MKOverlay) rendered on MapView, and overlay needs to refresh on point Drag(MKPinAnnotation). I have custom logic to handle drag behaviour of annotation, on annotation drag I do update the overlay. As point update, I create new overlay with updated coordinate and re-render it. iT slow down the performance after few overlay added. Additional Notes: Performance was quite good on iOS16 but on iOS17, it lags the perforce on point drag. When I say it the performance, it point drag lags so it slow the overlay rendering. I am using MKMapView inside SwiftUI. I am sharing code-snippet where it re-render the overlay. Please help with issue in my code implementation. func renderSegments(mapView: MKMapView, segmentPoint: FencePointAnnotation, renderNeeded: Bool = true) { mapViewModel.updateFencePointOrder() guard let activeLayer = mapViewModel.activeLayer else { debugPrint("Invalid active layer.") return } let segments = mapViewModel.activeFence.connectedSegmentsOf(vertex: segmentPoint) // Remove existing overlay. for overlay in mapView.overlays { if let overlay = overlay as? FenceOverlay { if overlay.layerId == activeLayer.layerId { mapView.removeOverlay(overlay) } } else if let overlay = overlay as? FenceSegmentPolyline { if overlay.layerId == activeLayer.layerId { for segment in segments.values where segment.identifier == overlay.identifier { mapView.removeOverlay(overlay) } } } } // When vertex removed the no need to add segment if renderNeeded { if let segments = mapViewModel.updatedSegements(segment: segments.map({$0.key})) { let updatedSegments = mapView.updatedSegmentsWithOffset(segments: segments, layer: activeLayer) mapView.addOverlays(updatedSegments) } } }
