Video freezing with FairPlay streaming on iOS 18
Since iOS/iPadOs/tvOS 18 then we have run into a new problem with streaming of FairPlay encrypted video. On the affected streams then the audio plays perfectly but the video freezes for periods of a few seconds, so it will freeze for 5s or so, then be OK for a few seconds then freeze again. It is entirely reproducible when all the following are true the video streams were produced by a particular encoder (or particular settings, not sure on that) the video must be encrypted device is running some variety of iOS 18 (or iPadOS or tvOS) the device is an affected device Known devices are AppleTV 4K 2nd Gen iPad Pro 11 1st and 2nd gen Devices known not to show the problem are all other AppleTV models iPhone 13 Pro and 16 Pro If we stream the same content, but unencrypted, then it plays perfectly, or if you play the encrypted stream on, say, tvOS 17. When the freezing occurs then we can see in the console logs repeating blocks of lines like the following default 18:08:46.578582+0000 videocodecd Ap

peer-to-peer networking for iOS, iPadOS, watchOS, tvOS
Our product (rockhawk.ca) uses the Multipeer Connectivity framework for peer-to-peer communication between multiple iOS/iPadOS devices. My understanding is that MC framework communicates via three methods: 1) infrastructure wifi (i.e. multiple iOS/iPadOS devices are connected to the same wifi network), 2) peer-to-peer wifi, or 3) Bluetooth. In my experience, I don't believe I've seen MC use Bluetooth. With wifi turned off on the devices, and Bluetooth turned on, no connection is established. With wifi on and Bluetooth off, MC works and I presume either infrastructure wifi (if available) or peer-to-peer wifi are used. I'm trying to overcome two issues: Over time (since iOS 9.x), the radio transmit strength for MC over peer-to-peer wifi has decreased to the point that range is unacceptable for our use case. We need at least 150 feet range. We would like to extend this support to watchOS and the MC framework is not available. Regarding #1, I'd like to confirm that if infrastructure wifi is avai

Are iPad apps that are closed with the red traffic light prevented from running background tasks?
In iOS Background Execution limits, I see this: When the user ‘force quits’ an app by swiping up in the multitasking UI, iOS interprets that to mean that the user doesn’t want the app running at all. iOS also sets a flag that prevents the app from being launched in the background. That flag gets cleared when the user next launches the app manually. However, I see that when I close an app on iPadOS 26 with the red X, the app doesn't appear in the multitasking UI. So are they treated as force closes and prevented from running background tasks?

[quote='801686021, rmahmud28, /thread/801686, /profile/rmahmud28'] So are they treated as force closes and prevented from running background tasks? [/quote] No. The close button is not equivalent to the ‘force quit’ gesture. Rather, it’s roughly equivalent to a feature you’ve been living with on previous iPadOS releases, namely choosing Close from the menu brought up by the three dot button at the top of the window.

iPad: How to prevent the new floating decimalPad when using a keyboard toolbar (iPadOS 26)
On iPad running iOS 26, UIKeyboardType.decimalPad sometimes appears as a floating keypad (compact panel) instead of the docked, full-width keyboard. Our app attaches a custom toolbar via inputAccessoryView, so the floating keypad hides the toolbar and breaks the flow. We’d like to opt out of the floating keypad or force the keyboard to remain docked when a toolbar is present. Environment Device: iPad (multiple models) OS: iPadOS 26.0 App type: UIKit Field: UITextField with keyboardType = .decimalPad We present a custom toolbar via inputAccessoryView Expected Docked (full-width) keyboard so the inputAccessoryView toolbar is visible and sized correctly. Actual A floating decimal keypad appears and covers content; our accessory toolbar isn’t visible/attached to it. Why this matters Our toolbar contains required domain actions (Done/Next, Previous). When the keypad floats, the user loses these controls. Questions Is there a supported way to opt out of the floating numeric keypad on iPad when using decima

Swift iOS iPadOS app for Smartcard Token PIV using CryptoTokenKit
Please excuse my lack of understanding of what are probably fundamental concepts in iOS/iPadOS development but I have searched far and wide for documentation and haven't had much luck so far. I am not sure that what I want to do is even possible with an iPad iPadOS app. Goals: Develop a Swift iPadOS app that can digitally sign a file using a PIV SmartCard/Token (Personal Identity Verification Card): Insert a PIV SmartCard/Token (such as a Yubikey 5Ci) into the lightning port of an iPadOS device iPad (NOT MacOS) Interface with the SmartCard/Token to access the user's PIV certificate/signature and use it to sign a file Question 1: How to get the PIV Certificate from SmartCard/Token/Yubikey into iPadOS keychain? * Do we need to get the PIV certificate into the iOS keychain? Is there another way to interact with a SmartCard directly? * This should prompt the user for their PIN? Question 2: How to get our Swift app to hook into the event that the SmartCard/Token is inse

Reply to Assistance Needed: Accessing Smartcard Certificates for Document Signing on iOS
[quote='801476021, nagarajan031, /thread/801476, /profile/nagarajan031'] CryptoKit / Security Framework [/quote] Security framework is the right approach here. You can use TKTokenWatcher to learn about tokens coming and going, but to actually sign data with a digital identity on a token you need to use Security framework. This is not super complex code, but there are some traps for the unwary. And, annoyingly, those traps are subtly different on iOS and macOS. I have a bunch of hints and tips in these threads: Swift iOS iPadOS app for Smartcard Token PIV using CryptoTokenKit Using CryptoTokenKit on iOS to read SmartCard certificates Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Foundation Models not working: "Model is unavailable" error on iPad Pro M4
I am excited to try Foundation Models during WWDC, but it doesn't work at all for me. When running on my iPad Pro M4 with iPadOS 26 seed 1, I get the following error even when running the simplest query: let prompt = How are you? let stream = session.streamResponse(to: prompt) for try await partial in stream { self.answer = partial self.resultString = partial } In the Xcode console, I see the following error: assetsUnavailable(FoundationModels.LanguageModelSession.GenerationError.Context(debugDescription: Model is unavailable, underlyingErrors: [])) I have verified that Apple Intelligence is enabled on my iPad. Any tips on how can I get it working? I have also submitted this feedback: FB17896752

Reply to IOS alternatives to DriverKit
Hi, We were planning on using DriverKit to develop a USB Driver on iOS for iPhone. Within the DriverKit website, it says ‘iOS16.0+' which led us to believe it was compatible with iPhones running iOS16.0+. Unfortunately, the API overlap between iOS and iPadOS means that our website doesn't do a very good job handling edge cases like an iPadOS-only API. However, this page describes exactly what parts of DriverKit are supported on iPadOS. However, it appears DriverKit is only available for iPads running iPadOS, and computers running macOS. Correct. DriverKit is not supported on iOS. Are there any alternatives that would allow us to create a device-specific USB driver for an iPhone running iOS? Not for general USB communication. MFi-licensed accessories can communicate with applications on iOS; however, that communication is through an MFi-licensed protocol (iAP2). General USB communication is not possible, even through the MFi program. __ Kevin Elliott DTS Engineer, CoreOS/Har

Reply to Tahoe Launchpad
The removal of Launchpad from macOS has cost me a huge amount of wasted time. It is quite baffling why Apple's engineering team thought this was necessary. There is no scenario in which Apple's few predefined categories could possibly ever address the long tail of real world application categories and user workflows. This is a point I make in depth below. Also, I am now encountering a bug preventing me from searching for apps by name, even if I could remember the name of my 250+ native and web apps, so I have no other choice but to scroll through over 250 icons to find the app I'm looking for. I honestly do not understand what the rationale was for this change by Apple. Vital functionality that I relied on with minute-to-minute frequency was replaced with a fundamentally broken one that costs me minutes where it previously took seconds to find apps. In fact it should be obvious that predefined app categories could not possibly address real world use cases and and that forcing users into them would break more

iOS 26 RC: Scope buttons never appear for integrated UISearchBar
When trying to use a UISearchController setup with a UISearchBar that has scope buttons, the search controller's scopeBarActivation property is set to .onSearchActivation, the navigation item's preferredSearchBarPlacement property is set to .integrated. or .integratedButton, and the search bar/button appears in the navigation bar, then the scope buttons never appear. But space is made for where they should appear. Some relevant code in a UIViewController shown as the root view controller of a UINavigationController: private func setupSearch() { let sc = UISearchController(searchResultsController: UIViewController()) sc.delegate = self sc.obscuresBackgroundDuringPresentation = true // Setup search bar with scope buttons let bar = sc.searchBar bar.scopeButtonTitles = [ One, Two, Three, Four ] bar.selectedScopeButtonIndex = 0 bar.delegate = self // Apply the search controller to the nav bar navigationItem.searchController = sc // BUG - Under iOS/iPadOS 26 RC, using .onSearchActivation results in the sco
