What is the recommended FFMPEG settings for encoding a video which can play on all apple devices, old and new. I would like the format to be in mp4 so that the video file is also compatible to android, windows (phone / pc) and linux. These are the current settings I have used and they do not work on iOS, These settings work great on Windows and Android but not on iOS. ffmpeg -i input_video.mp4 -c:v libx264 -crf 23 -profile:v baseline -level 3.0 -pix_fmt yuv420p -c:a aac -ac 2 -b:a 128k -movflags faststart -o output_video.mp4 I'm new to developing for iPhone/iOS. so thanks in advance.

Dear, I have a question regarding the approval of the app in the store. I upload the app and right after that it was put under review, but it's been 3 weeks and still under review. Is this time normal? Note: I have other apps and on average it took 4 days to get an answer. Thanks.

Hi, I was on my iPad but I turned it off by accident. I used a Touch ID to get back in but it kept failing, so then it told me to enter my passcode. Funny thing is the keyboard didn't show up at all! I tried turning it on and off, trying to get in with different ways, but those didn't work. I would send an image but it won't allow me.. Can someone please help and tell me what is happening here?

Years ago I used to use the Apple Pencil to play pubg. I used to move with my left hand and use the pencil in my right to control the view and shoot. I played today for the first time in a while and the pencil no longer works if my hand is already using the left side. Please tell me there’s a fix for this!!

When triggering a webkitRequestFullscreen event in response to a pointerdown event, the result is a fullscreen error. Using a pointerup event instead of pointerdown works fine. I'm using a <button> element to receive the event and in the event listener callback I'm attempting to call webkitRequestFullscreen() on a div. Is this expected behavior? note: this was observed using MacOS Simulator: iPad 9th Generation - iOS 15.4

Howdy from Germany. I try to add a local httpServer with swift-http-server (https://github.com/bjtj/swift-http-server). import SwiftUI import SwiftHttpServer @main struct MyApp: App {   init() {     print("init")     let server = HttpServer(port: 9090)           class GetHandler: HttpRequestHandler {               var dumpBody: Bool = true               func onHeaderCompleted(header: HttpHeader, request: HttpRequest, response: HttpResponse) throws {       }               func onBodyCompleted(body: Data?, request: HttpRequest, response: HttpResponse) throws {         response.status = .ok         response.data = "Hello".data(using: .utf8)       }     }           do {       try server.route(pattern: "/", handler: GetHandler())     } catch let serverError {       print(serverError)     }           let queue = DispatchQueue.global(qos: .default)     queue.async {       do {         try server.run()       } catch let error {         print(error)       }     }   }   var body: some Scene {     WindowGroup {       ContentView() // Standard ContentView     }   } } When I try to add the local network rights on macOS (Montery 12.4 21F79) in the Playgrounds.app (Version 4.1 (1676.15)) it crashes everytime I hit the (+) button. On iPad (Air 4th gen) with latest ipadOS it works fine. I can add the network rights and can serve the little hello page, by entering :9090/ As mentioned on macOS not possible. Of couse if I reload the Playgrounds project on the Mac, the local network rights are now included, but still on the mac the "Hello" page is not served. Any hints/tips how to solve this problem? Need I to add more rights? Do I have to report the crash somewhere? I have the crashlog. Thanks in advance. Alex PS: Background: I try to write a Playgrounds App which generates some output on a webpage, which then is served via the in-app webserver, which then is integrated on Obs via web page plugin...

Hi folks, I have an enterprise app which can be downloaded from safari. When I download the app from iOS 14.0 device it is throwing 'Unable to install Myapp, Please try again later' error. Whereas, the same build if I install through diawi link. It is working fine. Any help would be really appreciated. P.S: I have cleared safari history and website data.

Does anyone else have this problem/know a solution to fix this? Using a Logitech Smart keyboard/iPad Pro 12.9 1st gen/iOS 16 Developer beta.

I am trying out Stage Manager with iPad OS 16 and the recent M1 iPad Pro with 2TB space. I had hoped I could connect it via a USB-C cable but the iPad is detecting the LG monitor and it works fine when I select Mirror Screen in Arrangement but when I stop mirroring the screen I am getting a black screen. I am using the port of the iPad Pro to connect it to the display and no luck. Even if try it by connecting to the USB port on the Magic Keyboard itself it acts the same.

Hi - on iPadOS16 beta1, we have been experimenting with connecting to external 1080p and 4k monitors using TypeC on latest M1 iPads. It appears to only display full-screen (non-mirrored) when there is a HID device such as mouse connected. This makes sense as you need to be able to control the screen independently. However for a touch screen external display (e.g. INNOCN) that supports multi-touch, it does not work. iPadOS (and macOS) do not have any multi-touch drivers. Is there plans for iPadOS (and indeed eventually macOS) to support external multi-touch screens?

In iOS16, will there be an open dialog that combines Photos and Files? For any creative app, this seems like a common scenario…I want to open a photo from either the Camera Roll or Files to edit in my cool app. I would envision the left toolbar showing sources, such as: On My iPad, iCoud Drive, and Camera Roll. Currently, it’s a bit clunky and confusing for users to have two different choices just to open a photo for editing. Thanks! James

I am investigating an issue where the main thread appears to be hung. It believe I have reproduced it locally a couple times, but it is not very repeatable. Attached are 2 of the backtraces I generated after pausing the application. I see a dispatch_barrier_sync_f call which “submits a barrier function for execution and waits until that function completes”. This is happening on a number of threads which are all waiting on a ulock_wait. In both of the deadlocks, there is one thread that has a dispatch_barrier_sync_f which appears to be active. From what we could tell, it is stuck in the function pthread_from_mach_thread_np. I only have assembly code here, but here is some source. It appears to be converting from a mach_thread to a pthread. When I step through the assembly it appears to be stuck in the loop portion of iterating over the pthread list. It is not clear to me how this fixed loop could hang. Perhaps the memory is corrupted and it is not looping over a valid pthread list? This may be related to the issue posted here. Any help would be greatly appreciated, thank you StackTrace.txt StackTrace4.txt

When I connect the iPad with my MacBook pro the iPad is not visible on the device and simulator option in Xcode. When I connect the device it just blinks and disappeared from the device and simulator option. I check the photos apps there I am able to see the device but in the Xcode, the device is not showing. Can anyone suggest to me how to fix this? Thanks in advance.

I am developing an app for iphone only, including a monthly subscription. Receipt validation is done on the server side and using the framework's swiftystorekit. In the actual machine test, the receipt verification succeeds on the iphone, but it not succeed when on the iPad. The error code is as follows. —- 21002(The data in the receipt-data property was malformed or missing) —- In the review, it was rejected because it must be possible to display even apps that are not compatible with iPad. In the early stages of development, we planed to support iPad as well, and set xcode. While preparing to submit to the review, I deselected the app for iPad in the xcode settings. Is this affecting? It's as if the build is in store kit test mode only on the iPad. I can't find a reason why iphone can successfully perform receipt verification in a sandbox environment but iPad can't. I tried the following: · Clean the build and restart xcode · Try switching between the store kit test and the sandbox test alternately. · Check iPad support on xcode setting · Try installing the app on your iPad from a test flight But none of them changed the result. Can you give me an idea of ​​what fixes and changes I can try? I would appreciate it if you could teach me.

Hello, iOS dev noob here. I am working on the following: Unity 2019.4.34f1 WIndows 10 Build to iOS and transfer to macBook air on Monterey XCode 13.3 Crash Detail: App is crashing on one of our test devices an iPad Air Model MD785LL/B The Unity Logo Splash works fine. Then it loads my scene 1, which is just a splash page with a canvas and a single image, that loads fine. After 1 second it calls SceneManager.LoadScene and opens up scene #1, main menu, and this is where it crashes. Main menu never loads, and app moves to background with a black screen. I have eliminated anything on the Main Menu, by having my splash call another scene. No matter which scene it calls, the app crashes on this device after the basic splash ( our splash) Previous versions of same app built with xcode worked fine, but that was xcode 11, 2 years ago. Nothing new has been added to the app since. Xcode reports no errors, and pushing to app store has no issues. My app builds with no exceptions or errors for Android, PC, or iPhones, and iPads pro. It builds fine in Xcode and also in Unity. I have published several apps on IOS with no issues, with xcode 13 or previous version going back to xc10. What I have tried: I have tried all Unity forum, stack exchange, apple developer solutions for "Xcode ipad black screen crash" and "ios crash suggestd" and "libsystem_kernal.dylib" and many others to no avail. Based on posts from @eskimo, it seems that this looks like an Objective C that was trapped, possible similar to his posts about calling UIKit on a second thread. But my log shows this: Thread 1 crashed with ARM Thread State (64-bit) But my app and C# code doesnt pick threads, so I have no clue how to resolve this. Any previous iOS crashes or bugs that I had affected all iOS builds equally, or would not build at all. Last time, I had seen crashes after splash, it was usually due to some XCODE linked library needing to be added to Linked Binary with Libraries section on Build Phases. Or some asset plugin causing a library failures, but this app has no 3rd party assets. Any help would be greatly appreciated. CrashLog copy.txt

So i have been looking at the playground on iPad. You can change functions and so on but not all is clear. In the Sensor Arcade project where do the mushrooms come from and how can I change the images of mushrooms and the player? Also I want to make the project my own so to speak so I can continue to work on it. How do I do that?
