I am creating a voip app, I am trying to use call kit to answer calls, however audio doesn't seem to work when using callKit when looking at the systems logs I see
no server connection when checking background audio state, won't allow background audio!
background audio processAllowed = 0 for displayID com.apple.TelephonyUtilities
no server connection when checking background audio state, won't allow background audio!
background audio processAllowed = 0 for displayID {my app id}
I have the plist entries for background ui modes for voip, audio, fetch and background notifications along with the backgrounds modes for Voip, Audio, AirPlay, and Picture in Picture, Background notifications. I am unsure what to do about this, like my reading of the error is I can't use audio cause I am not connected to a server, but like is it any server, Am I suppose to connect to the voip call before setting up audio, I am not sure how to do that.

My question is simple, I do not have much experience in writing swift code, I am only doing it to create a small executable that I can call from my python application which completes Subcription Management.
I was hoping someone with more experience could point out my flaws along with giving me tips on how to verify that the check is working for my applicaiton. Any inight is appreciated, thank you.

For a component operating as a peripheral in a BLE connection, is it possible to tell if the user taps "Cancel" in the system's pairing request dialog?
None of the methods in CBPeripheralManagerDelegate appear to apply.
Hello Apple Developer Team,
Based on the mandate to update the APNs certificate by February 24, 2025 for certificate-based authentication, a question from the team has been brought up that maybe Apple or the community can help answer. Since our implementation uses token-based authentication, I’m seeking clarification on a couple of points:
1. Does the certificate update affect token-based connections at all?
2. What is the rationale behind updating certificates for certificate-based authentication, and are there any implications or benefits for developers using token-based authentication?
Understanding these details will help us ensure our system remains compliant and optimally configured. Any guidance or further clarification you can provide would be greatly appreciated.
Thank you!
Hello,
I'm trying to display some Duration in a live activity using a custom format, with the goal of displaying a match time (only minutes) as, e.g. 33', 45' (+2), etc.
For that purpose, I'm using a TimeDataSource<Duration>, so that it also updates automatically given a starting point.
I've implemented my custom FormatStyle, trying to somehow mimic the existing UnitsFormatStyle (which perfectly works with live activities) but just changing the format.
I've added conformance to DiscreteFormatStyle, and code-wise everything seems to be ok (if I've understood things correctly). It compiles and it even works as expected in a playground.
However, when trying to use it within the live activity, I'm getting these cryptic errors in the Console.app, and the live activity just turns into a view with placeholders
Failed to fetch view from archive at index 12: SwiftUI.AnyCodable<SwiftUI.(unknown context at $1d47f6af0).SafelyCodableRequirement>.(unknown context at $1d47fe410).Errors.noType(mangledName: "7SwiftUI18TimeDataFormattingO10ResolvableVy_AA0cD6SourceVAAE15DurationStorageOys0H0V_GAK28BlickLiveActivitiesExtensionE16MatchFormatStyleVG")
[624AEC37-13D9-4927-9F41-C3092B61E214] Failed to return view entry from archive for view model with tag listItem with error: SwiftUI.AnyCodable<SwiftUI.(unknown context at $1d47f6af0).SafelyCodableRequirement>.(unknown context at $1d47fe410).Errors.noType(mangledName: "7SwiftUI18TimeDataFormattingO10ResolvableVy_AA0cD6SourceVAAE15DurationStorageOys0H0V_GAK28BlickLiveActivitiesExtensionE16MatchFormatStyleVG")
Are there any limitations when it comes to live activities and these custom formatters? This whole error doesn't make sense, since I'm only aiming to update every minute, which should just be fine, the same thing I get with the UnitsFormatStyle.
For reference, this is my playground, which just works as expected:
import Foundation
import SwiftUI
import PlaygroundSupport
extension Duration {
struct MatchFormatStyle: DiscreteFormatStyle, Sendable {
let periodLength: Int
let overtime: Int
func format(_ value: Duration) -> String {
let (seconds, _): (Int64, Int64) = value.components
let minutes: Int = Int(seconds) / 60
let current: Int = periodLength + minutes + overtime
if current > periodLength {
return "\(periodLength)' (+\(current - periodLength))"
} else {
return "\(current)'"
}
}
func discreteInput(before input: Duration) -> Duration? {
let (seconds, _): (Int64, Int64) = input.components
let minutes: Int64 = seconds / 60 - 1
return Duration(secondsComponent: minutes * 60, attosecondsComponent: .zero)
}
func discreteInput(after input: Duration) -> Duration? {
let (seconds, _): (Int64, Int64) = input.components
let minutes: Int64 = seconds / 60 + 1
return Duration(secondsComponent: minutes * 60, attosecondsComponent: .zero)
}
}
}
extension FormatStyle where Self == Duration.MatchFormatStyle {
static func matchTime(currentTime: Int, periodLength: Int) -> Duration.MatchFormatStyle {
return Duration.MatchFormatStyle(periodLength: periodLength, overtime: max(currentTime - periodLength, .zero))
}
}
extension TimeDataSource<Date> {
static func matchDuration(for currentTime: Int, periodLength: Int) -> TimeDataSource<Duration> {
let minutesAhead: Double = Double(max(periodLength - currentTime + 1, .zero))
return TimeDataSource<Date>.durationOffset(to: Date.now.addingTimeInterval(minutesAhead * 60))
}
}
struct FooView: View {
let currentTime: Int = 36
let periodLength: Int = 45
var body: some View {
Text(
TimeDataSource<Date>.matchDuration(for: currentTime, periodLength: periodLength),
format: .matchTime(currentTime: currentTime, periodLength: periodLength)
)
.frame(width: 400, height: 200)
.font(.system(size: 50))
}
}
// Present the view controller in the Live View window
PlaygroundPage.current.setLiveView(FooView())
Any hints or suggestions are welcome, many thanks in advance.
I have noticed that when I select the app token of the youtube app to be blocked via a ManagedSettingsStore, the youtube website is blocked as well (which is a good and intended behavior IMO).
But how do I know in the ShieldConfigurationDataSource’s override func configuration(shielding webDomain: WebDomain, in category: ActivityCategory) -> ShieldConfiguration to which ManagedSettingsStore the WebDomain’s token is related?
We use different ManagedSettingsStores for different block purposes, which differentiate in their ShieldConfiguration.
Thanks a lot and have a great day!
I'm currently developing an app with mapkit which I may submit to the Swift Student Challenge. So anyways, the app will be used completely offline. I was wondering if there was any way to include very low resolution map tiles with the app files. That way, the app never needs wifi. However, I'm not sure if this is possible, especially since the map would need to be under 20 mb. Thanks.

Hi there,
I am planning an app that requires use of the Family Controls Entitlement to access data on the user's screen time.
I understand that this has to be requested from Apple before it can be used in production.
I have found the following form to request approval, but it requires an App and bundle ID, which suggests that approval can only be requested after the app has been developed.
https://developer.apple.com/contact/request/family-controls-distribution
I'd like to avoid the situation where I spend a lot of time on developing the app, only to find out that the Family Controls Entitlement will not be granted for my use case.
Is there any way that I can request provisional pre-approval for my app? Perhaps based on an app description and some mockups? Or, at least some idea of whether my particular use case is likely to be approved?
Thanks.
I'm writing an LDAP Browser app using SwiftUI. I tested my LDAP code using a command line app that uses the exact same libraries and it successfully connects to my LDAP server over a TLS connection. I did need to install the CA cert into the system keychain.
The SwiftUI version, using the exact same code and parameters returns an "Unknown CA" error. It works fine without TLS. Can anyone explain why certificate validation is different for a GUI app?

When using ssidPrefix in the descriptor and completing the AccessorySetupKit setup, I attempt to connect to the accessory's Wi-Fi hotspot using NEHotspotConfigurationManager joinAccessoryHotspot.
The connection fails with the following error:
Error Domain=NEHotspotConfigurationErrorDomain Code=1 "invalid SSID." UserInfo={NSLocalizedDescription=invalid SSID.}
I'm using a prefix that is at least 3 characters.
If I provide ssid instead of ssidPrefix it connects successfully.

When I install my application, it installs fine and everything works alongwith all the system level daemons but when I reboot the system, none of my daemons are getting launched and this happens only on MacOS 15x, on older version it is working fine.
In the system logs, I see that my daemons have been detected as legacy daemons by backgroundtaskmanagementd with Disposition [enabled, allowed, visible, notified]

Is there anything changed in latest Mac OS which is causing this issue? Also what does this status 2 means. Can someone please help with this error?

I'm simply trying to use a proxy to route a http request in Swift to measure the average round trip time of a list of proxies. I've went through multiple Stack Overflow threads on this topic but they are all super old / outdated.
format:host:port:username:password
I also added the info.plist entry:
NSAllowsArbitraryLoads -> NSExceptionDomains
When I call the function below I am prompted with a menu that says
"Proxy authentication required. Enter the password for HTTP proxy ... in settings"
I closed this menu inside my app and tried the function below again and it worked without giving me the menu a second time. However even though the function works without throwing any errors, it does NOT use the proxies to route the request.
Why does the request work (throws no errors) but does not use the proxies? I'm assuming it's because the password isn't entered in the settings as the alert said. My users will want to test proxy speeds for many different Hosts/Ports, it doesn't make sense to enter the password in settings every time. How can I fix this issue?
func averageProxyGroupSpeed(proxies: [String], completion: @escaping (Int, String) -> Void) {
let numProxies = proxies.count
if numProxies == 0 {
completion(0, "No proxies")
return
}
var totalTime: Int64 = 0
var successCount = 0
let group = DispatchGroup()
let queue = DispatchQueue(label: "proxyQueue", attributes: .concurrent)
let lock = NSLock()
let shuffledProxies = proxies.shuffled()
let selectedProxies = Array(shuffledProxies.prefix(25))
for proxy in selectedProxies {
group.enter()
queue.async {
let proxyDetails = proxy.split(separator: ":").map(String.init)
guard proxyDetails.count == 4,
let port = Int(proxyDetails[1]),
let url = URL(string: "http://httpbin.org/get") else {
completion(0, "Invalid proxy format")
group.leave()
return
}
var request = URLRequest(url: url)
request.timeoutInterval = 15
let configuration = URLSessionConfiguration.default
configuration.connectionProxyDictionary = [
AnyHashable("HTTPEnable"): true,
AnyHashable("HTTPProxy"): proxyDetails[0],
AnyHashable("HTTPPort"): port,
AnyHashable("HTTPSEnable"): false,
AnyHashable("HTTPUser"): proxyDetails[2],
AnyHashable("HTTPPassword"): proxyDetails[3]
]
let session = URLSession(configuration: configuration)
let start = Date()
let task = session.dataTask(with: request) { _, _, error in
defer { group.leave() }
if let error = error {
print("Error: \(error.localizedDescription)")
} else {
let duration = Date().timeIntervalSince(start) * 1000
lock.lock()
totalTime += Int64(duration)
successCount += 1
lock.unlock()
}
}
task.resume()
}
}
group.notify(queue: DispatchQueue.main) {

completion(0, "Proxies Failed")
} else {

Is there a way to detect an incoming call with a React Native app? I have a fitness app and would like to pause the workout during the phone call.
My question is: Do I need two App IDs? One for my launch daemon in order to sign it properly, allowing it to use the Endpoint Security framework. One for the container app.
My understanding is that my existing launch daemon can perform the endpoint security requirements I need. So far, I have had just one App ID for my container app that lives in /Applications.
I have applied for the endpoint security restricted entitlement and have this for development now.
Do endpoint security items have go in Library/SystemExtension? Can my launch daemon live in Library/LaunchDaemons and still use the Endpoint Security framework?

Instead of a .sdef file (or older formats) made in advance and stored in an app’s bundle, I wonder if the script dictionary can be set soon after the app opens? I seen related API, with a note that the scripting file reader ultimately calls that API. I grok about 90% of that API, but I’m not sure it’s possible.

Apps made through .net maui don't work with local networks.
I'm using the .net 8 framework, and I followed the app to the ios system through .net Maui after connecting it to the computer through a data cable.
When I open the app, I get a request to access the local network and I agree to it. But still my app is not accessible.
I have asserted it correctly inside info.plist.
How can I fix this issue
Hello,
I'm creating an app that stores multiple Date objects: the users selects a date and a time and receives a notification at this time precisely.
The problem that happens is after saving a Date, if the device's timezone changes, the Date also changes - and that is not what's I'm expecting (just want the original time as is without depending on timezone).
I have inspected the TimeZone properties when I'm building the Date from DateComponents but nothing has worked.
Thank you for your answer.
