Currently (at least for a few days, maybe longer), when trying to create an Apple Maps Web Snapshot according to https://developer.apple.com/documentation/snapshots/generating_a_url_and_signature_to_create_a_maps_web_snapshot with a custom image marker (passed as Base64 PNG), the Apple server responds with a 500 Internal Server Error. Using the default balloon marker works, but a custom Base64 image marker used to work in the past (and still should according to the documentation).

Hello all,
I have a food delivery app that I am beginning to implement CarPlay support in. Route picking, navigation, turn-by-turn guidance features all work perfectly on iPhone, and on CarPlay while the iPhone is unlocked, or locked but screen on.
However, when the iPhone is locked and the screen is off, the CarPlay map view stops following the user's location and appears to be frozen. When this happens, the other "map buttons" that are part of the CPMapTemplate continue to accept user input (I can enter and exit the map panning mode for example), the user's location continues to update, and the turn-by-turn guidance continues as normal. It appears to be just the map view (which is drawn on the window and is not part of the CPMapTemplate) that stops updating in this state.
I've been through every page of Apple documentation on CarPlay but nothing references or addresses how to keep the CarPlay session active while the iPhone is locked. I'm not sure where else to look for answers and I'm out of theories as to why this might happen.
Any guidance around this would be greatly appreciated.
Dear Apple Developer Support,
I am reaching out for guidance on implementing continuous directional and location updates in a watchOS app designed as part of a mapping/navigation solution.
Current Scenario:
We send continuous location and direction updates from our iOS app to the watchOS companion app.
When viewing directions on the Apple Watch, the screen dims after a short period, and the live data stops updating consistently, even though the user is actively looking at the screen.
This negatively impacts the usability of real-time navigation on watchOS.
Our Objective:
Prevent screen dimming (or extend screen-on time) while the user is viewing navigation directions.
Ensure reliable, continuous data updates on the watch screen during active navigation sessions.
Request:
We would appreciate your guidance on:
The recommended method to keep the watchOS screen active while displaying real-time navigation data.
Proper use of APIs such as WKExtendedRuntimeSession, WorkoutSession, or any other mechanism suitable for this use case.
Any best practices or App Store review considerations for apps that require extended screen time and continuous updates.
How such use cases were traditionally handled on watchOS and what has or hasn’t worked.
We want to ensure we're implementing this in a battery-efficient, user-respectful, and Apple-compliant manner.
Thank you for your assistance and guidance.
I have an error issue that I haven’t been able to solve despite doing extensive research. In fact the similar examples I have found so far have been educational but I have not been able to make work.

Hello,
Is it possible to retrieve URLs (the URL associated for the specified location) for the Place object when you query the Apple Maps Server APIs? They are available when you make a MKLocalSearch.Request() directly in Swift. We have both iOS and Android apps, and it's not currently possible to get the URLs on Android.
Thanks!
Hi everyone!
I’m a new developer diving into my first Apple Watch project, and I’m really excited to get started! This app relies heavily on using the most precise location data possible.
Could anyone point me to some official documentation or helpful resources on how to achieve high-accuracy location tracking specifically for watchOS? Any tips or best practices would also be greatly appreciated!
Thanks in advance for your help!
Description of the Bug:
Core Location intermittently reports inaccurate location updates, albeit with a high accuracy value. This problem occurs almost exclusively while travelling in metros underground affecting the ability to rely on the framework effectively.
Steps to Reproduce:
The user starts travelling on ground level at point A
The user continues travelling and, after some time, is now underground at point B. A stationary beacon scanned at point B confirms this.
Core Location is observed to deliver a location update with a high-accuracy value but with the coordinates around point A when the user is actually around point B.
Expected Behaviour:
Accurate locations should be delivered at all times. In other words, Core Location should not report location updates with high accuracy when its certainty is low.
Hello everyone,
I'm doing some work on validating some data to do with the zpseed functionality around corelocations, i've read up on the speedaccuracy field but the wording doesn't make sense to me. It says if its a positive number it is plus or minus the value in the zspeed column so would this be for example zspeed of 35 mps with an accuracy of 3 mps would it be 32 mps 38 mps or is it a range? so would it be anywhere between 32-38 mps. Or is it just plus or minus the 3mps and if this is the case how would it be worked out if its plus or minus when all the numbers will be a positive numbers as any negative numbers are deemed inaccurate ?

I have a marine navigation app which displays GPS quality information when receiving NMEA message from an external GPS. These include the number of satellites and Horizontal Dilution of Precision (HDOP).
As far as I can see, the only additional information available through location services (for devices with built in GPS) is horizontal and vertical accuracy.
Am I missing anything? Also does anyone know how horizontal accuracy is derived from HDOP?

Hello, I have noticed that some users have modified their real location through an app called "MGU" to bypass my app's security checks. I want to know how to protect my app and detect users using virtual location. I have reproduced the process of virtual positioning here:
Insert a plug-in through the interface at the bottom of the phone and connect it via Bluetooth on the phone
Set the desired positioning target on the "MGU" app
Turn off your phone's WiFi, network, and location for 10 seconds, then turn it back on
At this point, virtual positioning is successful.
Please assist me in troubleshooting this issue and inform me of the principle of implementing virtual positioning in this app and how to prevent it.
The following is the screen recording of virtual positioning operation:
https://flowus.cn/share/145b3232-26c3-4ea3-b3ff-4aad1495eb4d
We have a setup that's really close to the one used in the example project - Monitoring location changes with Core Location.
In short, we have a flag that indicates whether or not we should start background location monitoring. If the flag is on, after the app starts, we
Create a CLServiceSession with authorization: .always
Create a CLBackgroundActivitySession
The user can perform an action (press a button) to toggle the flag off, in which case we invalidate and dispose of the CLServiceSession and CLBackgroundActivitySession instances and cancel any liveUpdates observation.
So far, so good, everything works as expected.
However, we're experiencing a weird behavior on iPhones with Dynamic Island after there's an app update.
When the user is on the same app version, the behavior is correct.
have the flag on,
background location monitoring works fine,
when the app is in the the background, there's correctly a location indicator in Dynamic Island
the user can go back to the app and turn the flag off (disposing of instances, cancelling location observation), and when the app is in the background, there is no location indicator in Dynamic Island
The problem arises when the user updates the app
open version 1.0 of the app
have the flag on,
background location monitoring works fine,
when the app is in the the background, there's correctly a location indicator in Dynamic Island
download an app update - version 2.0
the app restarts, didFinishLaunchingWithOptions gets called again and we start the background services
dynamic island indicator is correctly showing a location indicator
the user goes into the app, toggles the flag off - turning location observation off, we dispose of everything
now, when the app is moved to the background, there's still a location indicator in the Dynamic Island, even though we're no longer observing location
The indicator is hard to get rid of, there are only 2 ways we've found
restart the device, or
uninstall the app
The question is - is this a bug in the system? Or is there anything we should be doing actively after an app update?
Thank you!
Hello,
I'm experiencing an issue with the Apple Maps URL scheme when using raw latitude and longitude coordinates in the daddr parameter.
Until recently, using a URL like this worked reliably:
https://maps.apple.com/?daddr=37.7749,-122.4194
This would open Apple Maps and show directions from the current location to the specified coordinates.
However, on recent iOS versions, this URL no longer behaves as expected.
I’ve just updated to Simulator 16.0 (104.1)
I’m currently developing my first app, which relies heavily on location data. It was simulating correctly before I updated Simulator. Since the update it is no longer receiving location data.
Is anyone else experiencing this problem?
Hello,
I’ve done a lot of testing of location services running in background with various settings, but in all scenarios location updates pause after a couple of hours, especially overnight In sleep mode.
My app, for personal safety, requires regular location updates to 5m accuracy every minute. The only solution I have found is to keep the app in foreground.
Location always stops updating. Background mode stops updating. Live location services stops updating.
Is there a solution I may have missed other than keeping app in foreground?
thank you,
Brendan
Hi,
I'm using MapKit's MKDirections.calculate, calculateETA, and reverse geocoding (via CLGeocoder.reverseGeocodeLocation) in my iOS app.
I understand that there are undocumented rate limits for these services to prevent abuse, but I couldn't find official details.
I would like to know:
Are the rate limits applied per device, per app installation, or are they shared across all users of the same app bundle ID?
Is there any guidance on how to design these features to avoid hitting rate limits in a production environment?
What is the best practice if a user repeatedly triggers routing or reverse geocoding (e.g., typing or moving the map)?
Any clarification or official documentation would be greatly appreciated. Thank you!
The other day I was playing with iBeacon and found out that CLBeaconIdentityConstraint will be deprecated after iOS 18.5. So I've written code with BeaconIdentityCondition in reference to this Apple's sample project.
import Foundation
import CoreLocation
let monitorName = "BeaconMonitor"
@MainActor
public class BeaconViewModel: ObservableObject {
private let manager: CLLocationManager
static let shared = BeaconViewModel()
public var monitor: CLMonitor?
@Published var UIRows: [String: [CLMonitor.Event]] = [:]
init() {
self.manager = CLLocationManager()
self.manager.requestWhenInUseAuthorization()
}
func startMonitoringConditions() {
Task {
print("Set up monitor")
monitor = await CLMonitor(monitorName)
await monitor!.add(getBeaconIdentityCondition(), identifier: "TestBeacon")
for identifier in await monitor!.identifiers {
guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
UIRows[identifier] = [lastEvent]
}
for try await event in await monitor!.events {
guard let lastEvent = await monitor!.record(for: event.identifier)?.lastEvent else { continue }
if event.state == lastEvent.state {
continue
}
UIRows[event.identifier] = [event]
UIRows[event.identifier]?.append(lastEvent)
}
}
}
func updateRecords() async {
UIRows = [:]
for identifier in await monitor?.identifiers ?? [] {
guard let lastEvent = await monitor!.record(for: identifier)?.lastEvent else { continue }
UIRows[identifier] = [lastEvent]
}
}
func getBeaconIdentityCondition() -> CLMonitor.BeaconIdentityCondition {
CLMonitor.BeaconIdentityCondition(uuid: UUID(uuidString: "abc")!, major: 123, minor: 789)
}
}
It works except that my sample app can take as long as 90 seconds to see event changes. You would get an instant update with an fashion (CLBeacon and CLBeaconIdentityConstraint). Is there anything that I can do to see changes faster? Thanks.
Hi all,
We’re running into a challenge with our iOS app DriveSmarter, which uses background location updates when connected to a physical Bluetooth device (e.g., dash cam, radar detector). For battery efficiency, we disable location services in the background when no device is connected. The problem we’re now facing is:
How can we programmatically re-enable location services when a Bluetooth device reconnects while the app is still in the background?
From what I understand, Core Location doesn’t allow re-enabling background location updates unless the app returns to the foreground. But our core use case requires this to happen seamlessly in the background when the user starts driving and the device connects again.
To clarify:
We stop location updates when the device disconnects.
We want to resume location updates only when the device reconnects, even if the app is still in the background.
Manually bringing the app to the foreground is not a reliable or user-friendly option.
So my questions:
Is it possible to programmatically restart background location services upon a Bluetooth connection event while staying in the background?
If not, are there any best practices or Apple-recommended alternatives to achieve a similar result?
Any guidance, patterns, or creative solutions would be greatly appreciated!
Thanks in advance
