I am trying to derive the Apple Place ID from a CLPlacemark (or via a MKMapItem derived from it) created via either CLGeocoder().reverseGeocodeLocation() or CLGeocoder().geocodeAddressString(). In many cases, the placemark returned from these functions contains detailed information (name, address, coordinates, etc), implying that the Apple Place ID is known, but the identifier is not present. The only way I have found to get a Place ID is via MKLocalSearch. Wondering if I am missing something here.

Am displaying a number of annotations on a map which vary their location over time and can inherently cluster together. I'd like to be able to set the Z order on the annotations as I have simple logic how to order them in the Z direction. I see the ZPriority property on UIKit Annotation view, but unclear how I can do that in SwiftUI. Is this exposed in any manner? I thought I could create a viewModifier and using the content parameter I'd be able to drop down into the UIKIt view to apply the value to the property, but alas I'm not seeing a clear way to do so. Is this at all possible without dropping down entirely to creating a NSViewRepresentable/UIViewRepresentable implementation of Map?

I have noticed a discrepancy between behavior on physical devices and simulators in iOS 18. I am using the latest MapKit APIs to fetch MKMapItems using the following MKLocalSearch: private func performLocalSearch(_ query: String) async throws -> [MKMapItem] { let request = MKLocalSearch.Request() request.naturalLanguageQuery = query let search = MKLocalSearch(request: request) return try await search.start().mapItems } This returns an array of MKMapItem on both the simulator and physical device. The key difference is my physical device (iOS 18.1.1) is missing the MKMapItem's identifier value. On the simulator, identifier is always populated in addition to my search. Any ideas on how to resolve this? The new MapKit API for those curious: @available(iOS 6.0, *) open class MKMapItem : NSObject { @available(iOS 18.0, *) open var identifier: MKMapItem.Identifier? { get }

I want to use a Map to show current location and heading, but the map first show, it just wont work. And when I switch off and switch on again, it works. codes below: BackgroundMapView.swift import SwiftUI import MapKit struct BackgroundMapView: View { var scope: Namespace.ID? private var cameraPosition: MapCameraPosition = .userLocation( followsHeading: true, fallback: .automatic ) private var locations: [Location] init(_ scope: Namespace.ID? = nil, locations: [Location]) { self.scope = scope self.locations = locations } var body: some View { Map( initialPosition: cameraPosition, scope: scope ) { MapPolyline(coordinates: locations.map({ $0.coordinate.toGCJ02 })) .stroke( .red, lineWidth: 3 ) } .mapControlVisibility(.hidden) } } #Preview { MainView() } HomeVIew.swift import SwiftUI struct HomeView: View { @StateObject private var locationManager = LocationManager() @State private var isMapEnabled = UserDefaults.isHomeMapEnabled { didSet { UserDefaults.isHomeMapEnabled = isMapEnabled } } @Namespace private var mapScope var body: some View { if isMapEnabled { BackgroundMapView(mapScope, locations: locationManager.locations) .mapScope(mapScope) } } }

Hi, would anyone be so kind and try to guide me, which technologies, Kits, APIs, approaches etc. are useful for creating a horizontal window with map (preferrably MapKit) on visionOS using SwiftUI? I was hoping to achieve scenario: User can walk around and interact with horizontal map window and also interact with (3D) pins on the map. Similar thing was done by SAP in their "SAP Analytics Cloud" app (second image from top). Since I am complete beginner in this area, I was looking for a clean, simple solution. I need to know, if AR/RealityKit is necessary or is this achievable only using native SwiftUI? I tried using just Map() with .rotation3DEffect() which actually makes the map horizontal, but gestures on the map are out of sync and I really dont know, if this approach is valid or complete rubbish. Any feedback appreciated.

I have a map application that needs to show a line (representing a direct route) that is above everything, including annotations. This is important because the map has lots of annotations (possibly hundreds) and the line is representing a route from point to another. With that many annotations being on top the line / route is basically useless because you can't see it. I've looked at things like MKOverlayLevel but it only supports .aboveRoads or .aboveLabels. Is there a way to set the z-axis of a map overlay so that it truly is on top of everything else on the map, including annotations? And if not directly in MapKit, what other options might I have? Worth noting that I'm targeting 16.4 and above, so that's my limitation on this

I have ran into an issue that is illustrated by the code in the following GitHub repository. https://github.com/dougholland/ColorTest When a SwiftUI color originates from the ColorPicker it can be persisted correctly and renders the same as the original color. When the color originates from the MapFeature.backgroundColor, it is always rendered with the light appearance version of the color and not the dark appearance version. The readme in the GitHub repo has screenshots that show this. Any assistance would be greatly appreciated as this is affecting an app that is in development and I'd like to resolve this before the app is released. If this is caused by a framework bug, any possible workaround would be greatly appreciated also. I suspect it maybe a framework issue, possibly with some code related to the MapFeature.backgroundColor, because the issue does not occur when the color originates from the ColorPicker.

https://developer.apple.com/documentation/applemapsserverapi/creating-and-using-tokens-with-maps-server-api This doesn't really say what to do with .p8 private key. I know I am a noob but I really don't understand Apple Doc at all. There is no example or anything like that. const appleMapKit = await fetch("https://maps-api.apple.com/v1/token", { headers: { Authorization: `Bearer ${server_api_token}`, }, }); This is what I did but because I created the token on website, server_api_token only lasts 7 days. So, I tried to use Profile - Key to replace that. I have .p8 file and how can I use this to create the token for the server api?

I have a Map within a SwiftUI. I initialize a variable like this: var cameraPosition: MapCameraPosition = .userLocation(followsHeading: true, fallback: .automatic) and then I want to zoom map, code like this: let userRegion = MKCoordinateRegion( center: userLocation.coordinate, span: MKCoordinateSpan( latitudeDelta: 0.01, longitudeDelta: 0.01 ) ) cameraPosition = .region(userRegion) But it does't work. How can I solve this problem?

I have a Map within a SwiftUI app that has the selection parameter set to an optional MapSelection. I need to be able to select MapFeatures which works as expected as well as MKMapItems which are added to the map. The MKMapItems are not selectable. Is it possible to make it such that the Map allows the user to select MKMapItems as well as MapFeatures?

Is it possible to get a MapFeature from an MKMapItem?

Hello, I've created an app that follows the user as they navigate through public transport. I want the camera to follow the user and at the same time I want the camera distance (elevation) to change dynamically depending on speed and other factors. I've tried a first approach using camera keyframes, but I've noticed a lot of crashes when the app comes back to the foreground. .mapCameraKeyframeAnimator(trigger: cameraFrame) { camera in KeyframeTrack(\MapCamera.centerCoordinate) { LinearKeyframe(cameraFrame.center, duration: cameraFrame.duration, timingCurve: cameraFrame.curve) } KeyframeTrack(\MapCamera.distance) { LinearKeyframe(cameraFrame.distance, duration: cameraFrame.duration, timingCurve: cameraFrame.curve) } } Some logs mention wrong center coordinates (nan, nan) but when I print them, it's show me valid coordinates. I've also tried manually setting the camera for each position update, but the result is not smooth. position = .camera( .init(.init( lookingAtCenter: newPosition, fromDistance: cameraElevation, pitch: .zero, heading: .zero) ) ) What's the best way to achieve this?

I have a Map in SwiftUI using MapKit and the map has several annotations and MapCircles added to it. I need to have the ability to center the map on a specific latitude and longitude. The issue is that the map instead is centering so that all annotations and MapCircles etc. are visible. How can I have it disregard items added to the map and center the map at a specific latitude and longitude and ideally, control the zoom level of the map also?

Hi, Have been trying to work with MapkitJS for a website, but I'm stumped on once basic capability: I want to be able to click on a point of interest, and perform some actions such as: Get its coordinates Attach an annotation to it (e.g. a callout) In my code, PointOfInterest's are selectable: map.selectableMapFeatures = [ mapkit.MapFeatureType.PointOfInterest, ]; But when I click on one, I do see the marker pop up but nothing else (which is not much help since there is no additional information in the marker itself). I see no event getting triggered that I can do something with. I am using an event listener as follows: map.addEventListener('single-tap', (event) => { const coordinate = map.convertPointOnPageToCoordinate(event.pointOnPage); console.log('Map tapped at:', coordinate); console.log('Map tapped event:', event); ... I guess I have to grab the Place ID somehow but I don't know how to. Thanks for any help.

We have to draw polygons inside a MKMapView based on coordinates retrieved from external source. It seems that MapKit does not behave correctly where polygons have single-vertex self-intersection. Here it's a simple point list example (every element is a pair of latitude and longitude values): [(0, 0), (20, 0), (10, 10), (20, 20), (0, 20), (10, 10), (0, 0)] The next image shows the rendering issue. But if the list is slightly changed in this way [(0, 0), (20, 0), (10, 10), (20, 20), (0, 20), (15, 10), (0, 0)] the issue disappears. The next image shows it. So it's not a self-intersection and self-tangency problem, but we think single-vertex self-intersection is a buggy edge case for MapKit. Right now we fixed this problem by finding the duplicated coordinates and applying a small offset (1e-8) to one of them, but it's a temporary solution and adds rendering delay. The problem is not due to iOS versions, since iOS 17 and 18 have the same issue. Also it happens on simulators and real devices. Here is the playground example, based mostly on the "Map Playground" template Xcode offers. If you run it without modifying it, the playground shows the "bugged" polygon. If you use notBugPoints instead of the default bugPoints for the polygon, the playground shows the "not-bugged" polygon. import MapKit import PlaygroundSupport // Create an MKMapViewDelegate to provide a renderer for our overlay class MapViewDelegate: NSObject, MKMapViewDelegate { func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer { if let overlay = overlay as? MKPolygon { let polygonRenderer = MKPolygonRenderer(overlay: overlay) polygonRenderer.fillColor = .red return polygonRenderer } return MKOverlayRenderer(overlay: overlay) } } // Create a strong reference to a delegate let delegate = MapViewDelegate() // Create an MKMapView let mapView = MKMapView(frame: CGRect(x: 0, y: 0, width: 800, height: 800)) mapView.delegate = delegate // Configure The Map elevation and emphasis style let configuration = MKStandardMapConfiguration(elevationStyle: .realistic, emphasisStyle: .default) mapView.preferredConfiguration = configuration // Create an overlay let bugPoints = [ MKMapPoint(CLLocationCoordinate2DMake(0, 0)), MKMapPoint(CLLocationCoordinate2DMake(20, 0)), MKMapPoint(CLLocationCoordinate2DMake(10, 10)), MKMapPoint(CLLocationCoordinate2DMake(20, 20)), MKMapPoint(CLLocationCoordinate2DMake(0, 20)), MKMapPoint(CLLocationCoordinate2DMake(10, 10)), MKMapPoint(CLLocationCoordinate2DMake(0, 0)) ] let notBugPoints = [ MKMapPoint(CLLocationCoordinate2DMake(0, 0)), MKMapPoint(CLLocationCoordinate2DMake(20, 0)), MKMapPoint(CLLocationCoordinate2DMake(10, 10)), MKMapPoint(CLLocationCoordinate2DMake(20, 20)), MKMapPoint(CLLocationCoordinate2DMake(0, 20)), MKMapPoint(CLLocationCoordinate2DMake(15, 10)), MKMapPoint(CLLocationCoordinate2DMake(0, 0)) ] let polygon = MKPolygon(points: bugPoints, count: notBugPoints.count) mapView.addOverlay(polygon) // Frame our annotation and overlay mapView.camera = MKMapCamera(lookingAtCenter: CLLocationCoordinate2DMake(10, 10), fromDistance: 5000000, pitch: 0, heading: 0) // Add the created mapView to our Playground Live View PlaygroundPage.current.liveView = mapView

I have been using the following python library to generate apple map snapshots. has worked fine until about ~12 hours ago - now all I'm getting is "bad request" for any snapshot with overlays. if it's just a snapshot with a defined center and no polyline overlays, it still works. perhaps something has changed with the api's way of parsing percent encoded parameters? it's super irritating that there's no changelog or source code to view. what the heck??? https://pypi.org/project/mapsnap/

Is it possible to let the user select points of interest on the Map, such as restaurants, grocery stores, gas stations etc. I want the user to be able to select these points of interest that are already on the map, not those that I add to the map. Is this possible with the SwiftUI version of the MapKit Map?

I'm using apple maps to build a feature so users can create and save running/cycling/hiking routes. Currently the map only shows trails and similar local paths after zooming in to what is basically an extreme level. I want the trails and local paths to be more visible on a further, broader level of zoom. APPLE MAPS JS EX: https://trkbucket.s3.amazonaws.com/media/shoe_images/Screenshot_2024-10-23_at_10.52.17AM.png https://trkbucket.s3.amazonaws.com/media/shoe_images/Screenshot_2024-10-23_at_10.52.04AM.png APPLE MAPS iOS EX: https://trkbucket.s3.amazonaws.com/media/shoe_images/IMG_9DDF5C9A320D-1.jpeg Also strange that on iOS the path is visible while more zoomed out whereas JS does not. Please advise how to show these map items at a broader zoom.

mapView.showsTraffic=true mapView.showsScale=true mapView.showsCompass=true mapView.showsUserLocation=true mapView.showsBuildings=true mapView.showsLargeContentViewer=true hi，guy，please help to see this problem，thankyou，the mapkit api support some showsfunction，but I can not find how to show the exit of subway in my own app，but the map app of appple shows the exit of the subway，so how can I show the exit of the subway stations by using mapkit
