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) } } }

Hi, I have a SwiftUI Map with a set of three annotations. These annotations move around, and I would like to animate their movement from one coordinate to another, but I'm not finding a way to do that. I've tried using withAnimation { } when setting my array of Identifiable models that back the Annotations, and I've tried adding the .animation(.default, annotationModels) modifier to my Map object (where annotationModels is the array that backs my Annotations). The animation modifier doesn't work on Annotation structs, and it doesn't work if I add the animation modifier within the Annotation's view either. Does anyone have any suggestions on how I might be able to animate the coordinates of annotations using a SwiftUI Map? Does the problem have to do with the fact that I have an array of these annotations?

when I click on a mapview pin, a PopupView comes up with some text and a button.

Hey, I have a problem. I was using MKMapView in my app, and in the view where I had a background at the top of the screen, in the example it was Color.red, it extended all the way to the top of the screen. Now, I wanted to switch to the newer Map and I'm seeing an issue because I'm getting a navigation bar that cuts off my color as I indicated in the picture. Does anyone know why this is happening and if there's another way to achieve this?

Hello, There are some countries, with political conflicts on borders, does MapKit JS support displaying the map depending on the point of view of the region ? if yes, how technically is done (like adding an attribute region on request params or something else) ? Thanks

Hi all, It wasn't extensively covered in the "Unlock the power of places with MapKit" at WWDC, but is it possible to add your own views to the mapItemDetailAccessory? The default view is great, but I would like to add a button for opening a new window showing another view. The documentation is rather limited at the moment so I thought I would ask here. Thanks in advance.

I'm creating an app where I'm recreating how Apple Maps shows the user location button - i.e, in a stack with a background. I'd like the MapUserLocationButton to follow the styling that it does in Apple Maps (i.e., when locked to the user location, it switches to a filled icon, instead of colouring the background. Is there a way to do this?

I'm on MacOS 15 Beta and Xcode 16 Beta. Running iOS 18 Beta on a 15 Pro Max. I'm leveraging the .mapItemDetailSheet(item: input) option to pull up a sheet that displays the Place Card for a selection made from a List of places. This is working great on my iPhone 15 Pro Max and my iPad Pro 13. I also have the Mac Catalyst option added under: Project \ General \ Supported Destinations If I launch the app from Xcode via the play button, the app functions fine on my MacBook Pro and I get logs in Xcode, etc. However, if stop the session in Xcode and attempt to run the same app on its own on my MacBook Pro, the mapItemDetailSheet does not populate with any information. Anyone have ideas on where the disconnect could be? Why would the sheet populate with data when ran from Xcode but not when ran on its own? Again, it runs fine on the iPhone and iPad. Any ideas would be helpful and appreciated.

I have been developing an app that includes some pinned locations. These are displayed on a map, and currently have the standard pins and SF Symbol pins. A few of the locations have a special symbol on Apple Maps, but the same symbol is not avalable in SF Symbols. I was wondering if it is possible to use the pins, other than the standard red, from Apple Maps.
