Could not located developer disk image for this device
I just downloaded xCode 26.0.1 and installed it overtop of my previous version of xCode (I don't know the version, but it was less than a year old). Everything was working fine with the previous version of xCode, but with v 26.0.1, I am getting the following popup error message when trying to install my app to some of my tethered devices: Could not located developer disk image for this device This occurs with an iPhone 7 with iOS 14.8 and an iPad Pro (1st gen) with iOS 13.5.1. Again, these devices had no problem launching an app from xCode while tethered prior to the v 26.0.1 install. I do have the following folders in the UsersMyNameLibraryDeveloperxCodeiOS DeviceSupport folder: 12.4.1 (16G102) 12.4.1 (16...2) arm64e 13.5.1 (17F80) 14.4.2 (18D70) 14.6 (18F72) 14.7.1 (18G82) 14.8 (18H17) 15.0.2 (19A404) 15.1 (19B74) arm64e 15.3.1 (19D52) 15.3.1 (19...2) arm64e 16.1 (20B82) arm64e 16.3.1 (20...7) arm64e

SwiftUI animation is laggy in NSStatusItem since macOS 26 Tahoe
My app is a bit of a special case and relies on a custom view in a NSStatusItem. I use a NSHostingView and add it as a subview to my NSStatusItem's .button property. Since macOS 26 Tahoe, even simple animations like a .frame change of a Circle won't animate smoothly even though the same SwiftUI animates normally in a WindowGroup. class AppDelegate: NSObject, NSApplicationDelegate { private let statusItem: NSStatusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength) func applicationDidFinishLaunching(_ aNotification: Notification) { let subview = NSHostingView(rootView: AnimationView()) let view = self.statusItem.button view?.addSubview(subview) subview.translatesAutoresizingMaskIntoConstraints = false guard let view = view else { return } NSLayoutConstraint.activate([ subview.centerXAnchor.constraint(equalTo: view.centerXAnchor), subview.centerYAnchor.constraint(equalTo: view.centerYAnchor), subview.widthAnchor.constraint(equalToConstant: 22), subview.heightAnchor.constraint(equalToCo

Reply to Question about PT Framework channel tone behaviour
And yes; there seems to be quite a conflict with using the term channel, especially combined with PTT. Yep. We used the name because the term channel is in such common use across PTT apps, but with the benefit of hindsight, the problem is that that channel SPECIFICALLY means varies enough between PTT apps that it ends up tripping developers up. API naming is hard, and this was a misstep. However, the good news is that the API itself has worked out very well, so I'll take that win! *For comparison, CallKit uses the term call for the same reasons the PTT uses channel, but I've never had ANYONE get confused about how calls work in CallKit. The difference is that every knows exactly how phone calls work in a way that isn't actually true of channels. __ Kevin Elliott DTS Engineer, CoreOS/Hardware

Unknown APNs ERROR: BadEnvironmentKeyInToken when sending Push To Talk notifications
We’re sending PTT notifications from our server and are receiving HTTP 403 from APNs for certain phones with the reason field BadEnvironmentKeyInToken. I can’t find this reason documented in Apple’s public error list. I’d like to confirm what this error specifically means and how to resolve it. Any guidance or clarification would be greatly appreciated. Thank you. Here is the document I was referring to. https://developer.apple.com/library/archive/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingwithAPNs.html

SwiftUI macOS Preview Crash When Using Custom Row Directly Inside List
I’ve hit a strange SwiftUI preview crash that happens on macOS previews when using a view inside a List’s ForEach, resulting in the error Fatal Error in TableViewListCore_Mac2.swift. Only crashes macOS preview - iPhone/iPad preview doesn't crash. Doesn't crash when actually running the app. Here’s a minimal reproducible example, causing the preview to crash. XCode: Version 26.0.1 (17A400) MacOS: 26.0.1 (25A362) import SwiftUI struct Item: Identifiable { let id = UUID() let name: String } struct ItemRow: View { let item: Item var body: some View { HStack { Button(action: {}) { Image(systemName: play) } Text(item.name) Spacer() ProgressView() } } } struct ContentView: View { @State private var items = [ Item(name: Item A), Item(name: Item B), ] var body: some View { List { ForEach(items) { item in ItemRow(item: item) } } } } #Preview(Content view) { ContentView() } #Preview(Item row) { ItemRow(item: Item(name: Item A)) } If I wrap the row in a container, like this: ForEach(items) { item in ZStack { Ite

Cluster not displaying in CarPlay POI template on iPhone 14 with iOS 26.0.1
I am experiencing an issue with the CarPlay POI template in my CarPlay application. On my iPhone 14 running iOS 26.0.1, the clustering of POIs on the CarPlay map is not displaying at all. However, this issue only affects this specific model and OS version. The same app works correctly on an iPhone 14 with iOS 18.5 and on an iPhone 16 Pro Max with iOS 26.0.1. There are no code changes between builds for each device.

App Switcher briefly flashes or disappears on iPadOS 26.0.1
I’m experiencing a strange issue with the App Switcher on my iPad. When I swipe up from the bottom to open the App Switcher, the apps that should be running sometimes don’t appear — they briefly flash for a split second and then disappear. The App Switcher itself stays open, but it shows no app cards. Here are some details: Device: iPad Pro (11-inch, 2nd generation) iPadOS version: 26.0.1 Reproducibility: Happens intermittently Steps to reproduce: Open several apps. Swipe up from the bottom and pause to show the App Switcher. Sometimes, the app cards flash for a moment and then disappear, leaving the App Switcher empty. Expected behavior: The App Switcher should display all running apps consistently. Actual behavior: The App Switcher appears, but the app cards briefly flash and disappear, leaving a blank screen. I’ve seen a few similar reports on the Apple Support Community, but I’m not sure if this is a known issue in iPadOS 26.0.1. Has anyone else encountered this problem? Any confirmations or work

Problem with Private Access Token (PAT)
Since October 3rd, I've stopped receiving responses to the Private Access Tokens challenge. I'm using this link: https://demo-issuer.private-access-tokens.fastly.com/.well-known/token-issuer-directory. I receive tokens from Fastly and return a header to the iOS app, but then I don't receive another authentication request from iOS. The user has automatic verification enabled on their phone. The problem is global and affects all my mobile app users. Has anyone encountered a similar problem and found a solution?

Reply to HoverEffectStyle in visionOS 26.0
hi @Vision Pro Engineer I have submitted FB20587228 (HoverEffectStyle in visionOS 26.0). I included a quick sample project. Upon further testing, it seems that the hover effect is not working in 26 if the entity is in front of the window (from the user's perspective). If I reposition the user's view so that the window is no longer behind the entity, the hover effect works. Thanks

iOS - record audio fails to record
Hi, I try to record audio on the iPhone with the AVAudioRecorder and Xcode 26.0.1. Maybe the problem is that I can not record audio with the simulator. But there's a menu for audio. In the plist I added 'Privacy - Microphone Usage Description' and I ask for permission before recording. if await AVAudioApplication.requestRecordPermission() { print(permission granted) recordPermission = true } else { print(permission denied) } Permission is granted. let settings: [String : Any] = [ AVFormatIDKey: kAudioFormatMPEG4AAC, AVSampleRateKey: 12000, AVNumberOfChannelsKey: 1, AVEncoderAudioQualityKey: AVAudioQuality.high.rawValue ] recorder = try AVAudioRecorder(url: filename, settings: settings) let prepared = recorder.prepareToRecord() print(prepared started: (prepared)) let started = recorder.record() print(recording started: (started)) started is always false and I tried many settings. Error messages AddInstanceForFactory: No factory registered for id F8BB1C28-BAE8-11D6-9C31-00039315CD46 AudioConverter.cpp
