Reply to CoreMediaErrorDomain Code=-12884
Hello. I am having the same problem with the same symptoms with an application I am releasing. Does anyone know the cause or solution? The situation is as follows. It occurs when I try to play a FairPlay video. Error Domain=NSURLErrorDomain Code=-1008 See -[AVPlayerItem errorLog] for 2 events UserInfo={NSDebugDescription=See -[AVPlayerItem errorLog] for 2 events, NSLocalizedDescription=リソースは利用できません, NSUnderlyingError=0x303fe8630 {Error Domain=CoreMediaErrorDomain Code=-12884 (null)}} This error does not occur for all users, only for some. The device used by the user that is experiencing this is an iPhone 16 Pro (18.2.1). The error seems to occur before accessing the license server. Thank you in advance for your support!

Reply to Microsoft Edge & Authenticator account login
Thanks for the reply. While that may be true, for you. I cannot login to outlook.com on Edge, Safari or Chrome. All those browsers want me to login to my Microsoft account or sync my setting. Upon clicking on and trying to login to my account on Safari or Chrome the screen goes blank, never to recover. When I try on Edge, it want me to use the Authenticator, which of course I cannot do either because it wants me to setup my account, which I cannot do because it will not log me in due to too many attempts. I cannot login to outlook.com nor any Microsoft address without first logging in to my account. It's a vicious loop of going no where. Anything associated with Microsoft on my phone is fubar'd. No Word, no Excel, no Outlook or anything associated with my account/syncs are possible. This issue is only on my iPhone 16 Pro! My iPad running 17.7 has no issues! Something must have gotten glitched with my Microsoft account when transferring my data for 13 Pro to 16 Pro

Reply to IOS 26 - Lock Iphone during install on "low battery" page
I was just in the same boat but was able to boot into DFU mode to resolve it. I was running the latest 18.5 beta on my iPhone 16 Pro Max. Decided to try the iOS 26 dev beta (like I do every year) and encountered my first soft brick situation...got stuck on the battery splash as described here. Putting the device in DFU mode (direct firmware update) allowed me to restore using my Mac. Keep in mind this will wipe your device, but I'm an iCloud user so not worried about that, and using my phone in general was most important to me. 9to5 Mac has a pretty good article on using DFU mode. Keep in mind when done right, you will not see an Apple logo or any splash, you'll see a black screen. Then when plugging into your Mac it will be recognized (unlike with the battery splash). Good Luck.

Reply to NSCocoaErrorDomain Code=513 after user delete's
I've reproduced this on these 2 setups using the same iCloud account: Xcode 26.0 beta 4 (17A5285i) & iPhone 12 running iOS 26.0 (23A5326a) Xcode 16.4 (16F6) & iPhone 16 Pro running iOS 18.6.1 (22G90) Deleting the iCloud data for the app from one device also allows me to reproduce the issue on the other device. The error printed in the sample project by the console is: You don’t have permission to save the file “Documents” in the folder “iCloud~com~hfriia~SimpleiCloudDocument1”. Failed to save a document! I just tested on this setup using another iCloud account and it functions as expected - I can immediately recreate the documents folder and save a document: Xcode 26.0 beta 4 (17A5285i) & iPhone 7 running iOS 15.8.4 (19H390) Xcode 26.0 beta 4 (17A5285i) & iPhone XR running iOS 18.6.1 (22G90) Maybe there's something wrong with the first iCloud account?

Reply to Local Push Connectivity - Unreliable Connection
Hi @DTS Engineer ! As we've taken some time to deep-dive into this, we're running into a dead-end here and are hoping to seek further guidance. To clarify, when our test iPhones (iPhone 15 on iOS 18.5, and iPhone 16 Pro on iOS 18.4) are locked and the app is backgrounded, the app extension will stop receiving the keep-alive messages over the SSE connection. Given our solution supports first responders, it is critical that the connection is stable to allow critical notifications to arrive as quick as possible. If the app does not receive the keep-alives from our local server within 5s, it tears down the connection and establishes a new one. While testing at home on an Eero router and TP Link Deco XE75 Pro, I have been unable to reproduce any issues with it. I will leave the phone, unplugged, with the app running in the background and it works as expected. Given this, we determined our issue was likely with the vendor who supplies our customer routers, which

ESP32 USB-C to iPhone 16 USB-C communication
Hi everyone, I am seeking clarification regarding the communication capabilities between an ESP32 microcontroller and Apple's latest devices, specifically the iPhone 16 Pro Max and iPad Pro, both equipped with USB-C ports. Background: MFi Certification: Historically, establishing communication between external devices and iOS devices required MFi (Made for iPhone/iPad) certification. But I remember this being necessary in the Lightning Cable to USB era. With the introduction of USB-C ports in recent iPhone and iPad models, there is an indication that MFi certification may no longer be necessary for certain peripherals. Perhaps I'm not confident on the terminology here: https://mfi.apple.com/en/who-should-join Project Requirements: I am working on a sensor research project that necessitates the collection of low-latency time-series data from an ESP32 microcontroller, which features a USB-C port. The data needs to be transmitted to an iPhone 16 Pro

Reply to UITextField Input Issue While Using Bilingual Keyboard in iOS 18
The issue you described is interesting to me, yet I failed to reproduce the issue by running your project. Here is what I tried: Download your project, build it with Xcode 16.0 (16A242d), and run it on my iPhone 16 Pro Max simulator + iOS 18.0 (22A3351). Type 123456 in the text field (with black background) in your app. At step 2, I observe that the output is 1-2-3-4-5-6-. I also switched the system language to Korea, and made sure the Korea & English (US) keyboard was in the keyboard list in Settings, but the result was the same. Do I need to do anything to be able to reproduce the issue. Secondly, did you try to use textField(_:shouldChangeCharactersIn:replacementString:), instead of .editingChanged? The delegate method is designed for confirming or replacing an input, which I think fits your use case. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Reply to Delay in notifications iPhone 16 Pro iOS 18.3
I’ve been experiencing the exact same issue since I purchased my iPhone 16 Pro on launch day in September, and it has not been fixed despite all the iOS updates I’ve installed. I have an open case with Apple Support, but every time I call for an update, a new supervisor takes over and tells me the same thing: that this is a software issue. We’ve tried everything—factory resets (twice), network and general settings resets multiple times, collecting logs, sending screenshots and videos, verifying all app settings, making sure DND isn’t interfering, and countless other troubleshooting steps. Nothing has worked. I’ve asked for a replacement, but they refuse, claiming it’s not a hardware issue. However, given how many people are reporting this, I can’t help but feel that this is an inherent hardware flaw in some iPhone 16 models. The fact that Apple keeps pushing updates without fixing it is frustrating. I just wanted to share my experience in case a developer sees this and can

Reply to Crashing when going from Compact to Two Over Secondary in UISplitViewController on iPadOS 17
We are seeing the same error when trying to hide toolbar in a view inside NavigationSplitView on iPhone 16 Pro Max simulator running iOS 18. This crashes when rotating the phone to landscape when the view is open and toolbar hidden. We would sometimes want to hide the toolbar in compact mode, but haven't found a good solution yet. import SwiftUI enum NavigationDestination: Hashable, Codable { case home } struct ContentView: View { @State var columnVisibility: NavigationSplitViewVisibility = .all @State var navigationPath: [NavigationDestination] = [] @ViewBuilder var sidePanel: some View { VStack { Button(Home) { navigationPath.append(.home) } } } var body: some View { ZStack { NavigationSplitView( columnVisibility: $columnVisibility, sidebar: { sidePanel }, detail: { NavigationStack(path: $navigationPath) { ZStack {} .navigationDestination(for: NavigationDestination.self) { d in switch d { case .home: HomeView() } } } } ) } } } struct HomeView: View { var body: some View { VStack {

Reply to ESP32 USB-C to iPhone 16 USB-C communication
[quote='772812021, maxwendysh, /thread/772812, /profile/maxwendysh'] Is MFi certification still required for an ESP32 microcontroller to communicate with iPhone 16 Pro Max or iPad Pro via USB-C? [/quote] This is one of those places where iOS and iPadOS differ. On iPadOS you can use DriverKit to communicate with a custom USB device. That’s not an option on iOS. Both iOS and iPadOS support MFi, so you could build it that way. [quote='772812021, maxwendysh, /thread/772812, /profile/maxwendysh'] Do the iPhone 16 Pro Max and iPad Pro natively support serial communication over USB-C with microcontrollers like the ESP32? [/quote] Not in the way you’re looking for. Both iOS and iPadOS have built-in support for a wide range of USB classes, and device in that class appear are accessible via higher-level APIs: a PIV device is visible to the system via CryptoTokenKit, an audio device via our extensive audio API, and so on. However, the list of supported classes doesn’

Reply to Apple Carplay iOS 18 and Toyota
This started happening to me 1 week ago. 2022 Toyota Rav4 XSE Hybrid, wired CarPlay, though I was using a bluetooth adapter for wireless CarPlay at the time. iPhone 16 Pro, iOS 18.2.1, though I was already running this when CarPlay went kaput. I drove the car to a store using CarPlay and Google Maps just fine, turned off the car for about 5 minutes, and ever since then, no CarPlay. I've removed the bluetooth adapter, tried many different USB cables directly, and nothing. My phone charges over USB no problem. I've tried all of the troubleshooting tips I can find, both on the iPhone and Toyota's infotainment system. Yes, I have turned it off an on again. My system is up to date according to the firmware page @GreenEagle posted, if you can call 2021 up to date. It's driving me bonkers, especially since I don't believe I've seen a single actual solution on the web. I didn't realize how much I rely on CarPlay until it stopped working.

Screen stays on after notification iOS 18 - 16 pro max
after my phone receives a notification, the screen stays on. i Waited 15 minutes and did not go off (fully lid) battery drained 5%. Always on display was set to OFF. Restarting the phone solved the issue, but home & loch screen has been my No..1 battery use since I have the iPhone 16 (2 weeks). never saw that app using battery in the previous 10 year of iPhone use. My new iphone 16 pro max does not appear to have much more battery life than my previous 12 pro max with battery cap at 83%

Reply to Can't change iPhone watch app complication picker app name
The name should be the bundle display name of the watchOS app, and I just confirmed that with the Transferring data with Watch Connectivity sample and the following steps: Download the sample and manage to run the app on my iPhone and paired Apple Watch. In the iOS Watch app, find the section name shown in the first screenshot in the original post, and confirm it is SimpleWatchConnectivity Watch App. In the Xcode project, find the Bundle display name entry in the Info.plist of the watchOS app, confirm that the value is SimpleWatchConnectivity Watch App as well. Change the value of the entry to SimpleWatchConnectivity, then run the app again. In the iOS Watch app, confirm that the section name is now SimpleWatchConnectivity, consistent with the new bundle display name. I tested with iPhone 16 Pro + iOS 18.4.1 and Apple Watch Serial 10 + watchOS 11.4(22T251). The project was built with Xcode 16.2 (16C5032a) on macOS 15.4.1 (24E263). If you see a different result with the same test, I'
