I have a sample that stop working on IOS 26, using the latest XCode and IOS sdk, the onTapGesture event is no longer happening. Maybe this is no longer the way to drop pins on the map. Also not working on the iPhone 17 sim or iPhone 16 max pro device upgrading to IOS 26 Thanks, any help Sample: import SwiftUI import MapKit import CoreLocation import Foundation struct Pin: Identifiable { let id = UUID() let coordinate: CLLocationCoordinate2D } struct ContentTestPinDropView: View { @State private var pins: [Pin] = [] var body: some View { MapReader { reader in Map(selection: .constant(nil)) { ForEach(pins) { pin in Marker("Pin", coordinate: pin.coordinate) } } .onTapGesture { screenPoint in if let coordinate = reader.convert(screenPoint, from: .local) { pins.append(Pin(coordinate: coordinate)) } } } } }

I am encountering a coordinate rendering issue using MKMapView in my iOS app. I have a GPS coordinate in WGS84 format, which corresponds to a location in Hong Kong. When my device is physically located in Hong Kong, MKMapView displays the map with the "Apple Maps" label, and the WGS84 coordinate is rendered at the correct position. However, when the device is in Mainland China, MKMapView switches to display "Amap" (Gaode Maps) branding, and the same WGS84 coordinate is rendered at an incorrect position. I understand that Amap in Mainland China uses the GCJ-02 coordinate system, while Apple Maps typically uses WGS84. This discrepancy suggests a potential coordinate system mismatch, but I cannot definitively confirm which map type (and corresponding coordinate system) MKMapView is actually using in different regions. My key questions are: How can I programmatically or visually confirm the underlying map type (Apple Maps vs. Amap) and its coordinate system within MKMapView? Is there a way to simulate the Apple Maps environment for testing when physically located in Mainland China?

When building with iOS 26 SDK beta 5 (23A5308f), onTapGesture is no longer being triggered on Map views. This appears to be a regression in beta 5 specifically, as this issue was not present in beta 4. How to reproduce Code The following code demonstrates the issue, as seen in the videos below. import MapKit import SwiftUI struct ContentView: View { @State private var location = CGPoint.zero var body: some View { Map() .onTapGesture { location in self.location = location } .safeAreaInset(edge: .bottom) { VStack(alignment: .center) { Text("iOS \(UIDevice.current.systemVersion)") .font(.largeTitle) Text("Tapped Location") Text("\(location.x), \(location.y)") } .frame(maxWidth: .infinity, alignment: .center) .background(.background) } } } Demo The gifs below show the behavior in iOS 18.5 (in which the tap gestures are recognized and tapped coordinate is displayed in the safe area inset) and iOS 26 beta 5 (in which the tap gestures have no effect): iOS 18 iOS 26 Next steps? Is there a recommended workaround for this issue?

Reported as FB20357097 In SwiftUI, an empty .safeAreaInset modifier attached to a Map causes the map to become zoomed out to planet level. Minimal reproduction: import SwiftUI import MapKit @main struct map_region_safe_area_inset_bugApp: App { var body: some Scene { WindowGroup { Map { // Any Map content MapCircle(center: .init(latitude: 35.6895, longitude: 139.6917), radius: 1000) } .safeAreaInset(edge: .top) { // No content, `EmptyView()`, `Color.clear` } } } } Note: ZStack { } inside the safeAreaInset prevents the bug. Empty safeAreaInset (bug) Non-empty

I am having a problem with the following scenario. The user opens the Maps app, then selects a location like a store or restaurant, then tap on share and then on my app. On iOS 26, my app stopped showing altogether. After changing the NSExtensionActivationRule to TRUEPREDICATE to accept all, I see this difference between the OS versions. iOS 18.5 (lldb) po extensionContext?.inputItems ▿ Optional<Array<Any>> ▿ some : 1 element - 0 : <NSExtensionItem: 0x60000000c5d0> - userInfo: { NSExtensionItemAttachmentsKey = ( "<NSItemProvider: 0x600002930d20> {types = (\n \"public.plain-text\"\n)}", "<NSItemProvider: 0x600002930c40> {types = (\n \"com.apple.mapkit.map-item\"\n)}", "<NSItemProvider: 0x600002930bd0> {types = (\n \"public.url\"\n)}" ); NSExtensionItemAttributedContentTextKey = {length = 329, bytes = 0x7b5c7274 66315c61 6e73695c 616e7369 ... 656e7472 61616c7d }; "com.apple.UIKit.NSExtensionItemUserInfoIsContentManagedKey" = 0; } iOS 26 (lldb) po extensionContext?.inputItems ▿ Optional<Array<Any>> ▿ some : 1 element - 0 : <NSExtensionItem: 0x60000000cbd0> - userInfo: { NSExtensionItemAttachmentsKey = ( "<NSItemProvider: 0x60000293afb0> {types = (\n \"public.url\"\n)}", "<NSItemProvider: 0x60000293bf70> {types = (\n \"public.plain-text\"\n)}" ); "com.apple.UIKit.NSExtensionItemUserInfoIsContentManagedKey" = 0; } Please notice how iOS 26 is no longer sending com.apple.mapkit.map-item. Is there an alternative way to read the info from the map location shared to my app?

As GeoCoder is now deprecated I am struggling to get the country only information from the new MKReverseGeocoding. Maybe someone can guide me or give me direction? Or is this just not possible anymore? let request = MKReverseGeocodingRequest(location: self.lastLocation ?? fallbackLocation) request?.getMapItems { items, error in guard let items = items else { return } self.cityName = items.first?.addressRepresentations?.cityWithContext ?? "" self.countryName = items.first?.addressRepresentations?.regionName ?? "" } I couldn't find anything here, sure you can get the full Address but I need single values to store so the user can search for (example City, Country) In case the structure is always the same, let us say the country is always third part, sure I could split the string but it is not a reliable way to do this, at least for me. Any help would be much appreciated.

I have the following code snippet with a simple map and map reader that shows a pin on the map when the user selects a location struct MapReaderTest: View { @State private var loc: CLLocationCoordinate2D? = nil var body: some View { MapReader { proxy in Map { UserAnnotation() if let loc { Marker(coordinate: loc, label: { Text("Marker") }) } } .onTapGesture { position in let position = proxy.convert(position, from: .local) loc = position } } } } This snippet compiles and works perfectly fine using Xcode version 16.4 building for iOS 18.0 and running on a device. This snippet also works for me when I build using Xcode 26 Beta and run in the canvas or simulator, however it does not work when I compile using Xcode 26 and run it on a physical device(I built and tested for both iOS 18.6 and iOS 26 Beta) Has anyone else had a similar issue / have any ideas for work arounds?

Hi everyone, I’m building an iOS 18+ app in Xcode where Apple Maps is central. My goal is to start with the default Apple Maps experience (map view, search bar, pins, directions sheet, etc.) and then customize it for my project. I tried coding it from scratch using MapKit and SwiftUI, but I wasn’t able to get full parity with the basic features of the Maps app. My questions: Is there any sample project, template, or reference that provides the default Apple Maps functionality (views + interactions) as a baseline? Can I copy these into my Xcode project and then extend/customize them? If not, what’s the recommended best practice to get as close as possible to the native Maps app before adding my own features? Any guidance, sample code, or documentation links would be greatly appreciated.

The following code causes an error in Xcode 26.0 beta3 in iOS Simulator with iOS 26.0. After starting the App, scroll to the end of the grid and the app will break. Testet with Xcode Playground with platforms: [ .iOS("17.0")], Simplest possible variant: import SwiftUI import MapKit struct ContentView: View { var body: some View { NavigationStack { ScrollView { LazyVGrid(columns: [GridItem()]) { ForEach(1...12, id:\.self) { i in Text("Hello \(i)") .frame(height: 150) } Map { } .frame(height: 150) } } } } } Thrown error: Observation tracking feedback loop detected!

Hello Apple support, I have this following code Map(position: $mCam, selection: $lastSelection) { // Display content conditionally based on camera scope. // ^^^ works with user gesture, does not work with mapCameraKeyframeAnimator } .onMapCameraChange(frequency: .continuous , { context in // save the camera scope }) .mapCameraKeyframeAnimator(trigger: self.trigger, keyframes: { camera in // frames }) Context: when logging, the .onMapCameraChange is updating. The content mapContentBuilder is running. But the content is NOT showing up on the map. MapCircle, MapPolyline does not show! however, Marker works just fine Question: Anyone know How to indicate to MapKit Map view to draw the content? Or how to have a slight "break" between animation keyframes, so map can catch up.

Project minimum iOS deployment is set to 16.4. When running this simple code in console we receive "Observation tracking feedback loop detected!" and map is unusable.

Hi, I’m using SwiftUI’s Map with custom Annotation content and trying to make the annotation view ignore touch interactions—similar to applying .allowsHitTesting(false) on regular views. The goal is to ensure that map gestures such as long press and drag are not blocked by annotation content. However, setting .allowsHitTesting(false) on the annotation content doesn’t seem to have any effect. Is there any workaround or supported approach to allow the map to receive gestures even when they originate from annotation views? Thanks in advance for any guidance!

When navigated to another view with a NavigationStack or NavigationView, the .navigationTitle modifying a List or Form containing a Map() gets quirky when trying to show the title. The back button is displayed correctly, but the title does not follow the same color scheme as the List of Form, rather it is white with a divider underneath it. It's like it is confusing the .inline with the .large navigation display modes. This doesn't just show up in the simulator, but on actual devices too. This is a test main view... import SwiftUI struct ContentView: View { var body: some View { NavigationStack { NavigationLink(destination: MapErrorView()) { Text("Map View") } } } } This is a test navigated view... import SwiftUI import MapKit struct MapErrorView: View { var body: some View { NavigationStack { Form { Section(header: Text("Map of the US States")) { Text("Map Error") Map() .frame(height: 220) } } .navigationTitle("Map Error") .navigationBarTitleDisplayMode(.large) } } } Attached is an image showing this error occurring. Does anyone know how I can get around this without using Text() to mock it? That might be the only way to get around this error.

I have a map view that is presented as a modal in a navigation bar with a title view. The navigation bar is completely transparent in iOS 26 and the bar button items are displayed with a glassy effect. Since there is no soft edge effect, like we have on scroll views, it can be hard to read the text in the title view. Is there a way to get the soft edge effect on a map view that has a navigation bar? Not sure if I'm missing something obvious.

Hello everyone, I have just started coding using swift and I´m currently building an app that ist using MapKit. It is required to run on iOS 14 and newer and I want to add a Map switcher to switch between the Map Views Standard, Satellite, Hybrid and eventually also OSM. However this apparently is not as straight forward as it seems and I just don't get it to work. I had multiple attempts such as these two, each interface with a separate MapSwitcherView that open on the press of a button: var body: some View { ZStack(alignment: .bottomTrailing) { Group { if selectedMapStyle == .openStreetMap { openStreetMapView() } else { MapContainer(region: $locationManager.region, tracking: $tracking, style: selectedMapStyle) } } .id(selectedMapStyle) .onChange(of: selectedMapStyle) { newStyle in print("Style changed to: (newStyle)") } and Group { switch selectedMapStyle { case .standard: Map(coordinateRegion: $locationManager.region, interactionModes: .all, showsUserLocation: true, userTrackingMode: $tracking) .id("standard") case .satellite: Map(coordinateRegion: $locationManager.region, interactionModes: .all, showsUserLocation: true, userTrackingMode: $tracking) .id("satellite") case .hybrid: Map(coordinateRegion: $locationManager.region, interactionModes: .all, showsUserLocation: true, userTrackingMode: $tracking) .id("hybrid") case .openStreetMap: openStreetMapView() } } Unfortunately the map just doesn't switch. Do you have any suggestions? Should I post some more code of the MapSwitcher or something? Thanks and best regards

Hi, has anyone noticed that when using SwiftUI the MapKit Marker created with Marker(item: MKMapItem) .tint(.red) //solid flat color ignores the default marker styling (the nice gradient and shadow) and shows only a flat solid fill? The shadow/gradient appears correctly with some colors like .blue or .orange, but disappears with others such as .red, .purple, etc. What’s odd is that this happens only with the init(item: MKMapItem) initializer. A marker created with, for example, following init works just fine. Marker("hello", coordinate: CLLocationCoordinate2D) .tint(.red) //nice shadow/gradient Is this a bug, or does a marker backed by an MKMapItem support only a limited color range? (If so, exposing .tint there seems inconsistent—either all colors should work or none.) Has anyone else run into this problem? .orange with shadow/gradient: .red solid without shadow/gradient:

In my app, I want to launch Apple Maps and start turn-by-turn navigation when the user taps a button. I referred to Apple’s documentation and sample projects and implemented the following code: if let url = URL(string: "maps://?t=m&amp;amp;amp;daddr=(addr)") { self.carplayScene?.open(url, options: nil, completionHandler: nil) } This works only if Apple Maps has been launched at least once on the iPhone or in the CarPlay environment. If Apple Maps has never been opened before, it launches the app but does not automatically start navigation. However, once the user has opened Apple Maps at least once — either on the phone or through CarPlay — then navigation starts as expected from that point on. Is this behavior expected? Or is it a bug?

I'm building a weather map that shows the rain on the map. I'm able to retrieve PNG images that are used as tiles to put onto the map. I then reload all the tiles on the map with each timeframe (tile set for every 10 minutes). I'm able to get the map loaded up and I'm able to place the tiles and reload the data for each time slot. I preload all the PNG data needed for the tiles and store that NSData for them in memory so that they are quick for loading and showing on the map. I have timer's set to reload the overlay with the next set of tiles for each time slot. Giving the view of a moving precipitation map over time (just like you'd see on any weather map.) I have 12 time slots (timestamps) showing every 10 minutes for the past 2 hours. I have it showing each in sequence and then repeating. Over time I get a crash with this error as a Thread 1: signal SIGABRT. Failed to acquire drawable, rendering to temporary texture validateRenderPassDescriptor:782: failed assertion `RenderPass Descriptor Validation MTLRenderPassAttachmentDescriptor MTLStoreActionMultisampleResolve store action at attachment 0 requires resolve texture ' validateRenderPassDescriptor:782: failed assertion `RenderPass Descriptor Validation MTLRenderPassAttachmentDescriptor MTLStoreActionMultisampleResolve store action at attachment 0 requires resolve texture ' Through some searching I've discovered that this seems to be console output from Metal. I assume Metal is used for MapKit to render the overlay tiles? I'm using the same custom overlay where I set the timestamp on it and then tell it to reload. I also reuse the same MKOverlayRenderer as shown here... - (MKOverlayRenderer*)mapView:(MKMapView*)mapView rendererForOverlay:(id<MKOverlay>)overlay { if ([overlay isKindOfClass:[MKTileOverlay class]]) { if (!self.rainRenderer) { self.rainRenderer = [[MKTileOverlayRenderer alloc] initWithTileOverlay:overlay]; self.rainRenderer.alpha = 0.5; } return self.rainRenderer; } return nil; } And here's the function that reloads the overlay... - (void) updateRainFrame { self.currentFrameIndex = (self.currentFrameIndex + 1) % self.timestamps.count; if ((self.currentFrameIndex >= 0) && (self.timestamps.count > self.currentFrameIndex)) { NSLog (@"self.currentFrameIndex = %lu", self.currentFrameIndex); NSString *timestamp = self.timestamps[self.currentFrameIndex]; [self.overlay setTimestamp:timestamp]; [self.rainRenderer reloadData]; } } The time it takes to crash seems arbitrary. Sometimes it's very quick. Less than a minute. But usually it's several minutes. 10 or 20 minutes or more. Feels like some sort of race condition that's occurring. Perhaps ARC is not able to release the images for the tiles quick enough for each overlay reload? That's a wild guess but I think it's something more deeper in Metal as I feel I would see other errors related to memory availability. Some of my searches point to something about MSAA needing to be turned off in Metal to resolve this. However I have no idea how I would do that through MapKit. Any suggestions? Let me know if there is somehow a way to capture more from the crash to give more insight.

Hello! Since iOS 26, MKMapView annotations are unable to render P3 color in the marker style. Regular colorscontinue to work fine, but we make extensive use of this annotation style in our app. Filed as FB17910834

Our backend management system uses Google for Location, and Apple Maps is just one of the solutions in our map component. When should I convert coordinates to GCJ02? Maybe you would say that when you are in mainland China？ BUT NOT AT ALL! What if the user does not enable location permission? What if the user has not inserted a SIM card? Or not Chinese SIM card but location in China? OR the user location in China, But use VPN with en overseas IP? All solutions are not perfect, unless you open the API to developers and tell us whether Apple Maps currently uses the wgs84 coordinate system or gcj02, which is the most reliable.
