WKWebView Crashes on iOS During YouTube Playlist Playback
I’m encountering a consistent crash in WebKit when using WKWebView to play a YouTube playlist in my iOS app. Playback starts successfully, but the web process terminates during the second video in the playlist. This only occurs on physical devices, not in the simulator. Here’s a simplified Swift example of my setup: import SwiftUI import WebKit struct ContentView: View { private let playlistID = "PLig2mjpwQBZnghraUKGhCqc9eAy0UbpDN" var body: some View { YouTubeWebView(playlistID: playlistID) .edgesIgnoringSafeArea(.all) } } struct YouTubeWebView: UIViewRepresentable { let playlistID: String func makeUIView(context: Context) -> WKWebView { let config = WKWebViewConfiguration() config.allowsInlineMediaPlayback = true let webView = WKWebView(frame: .zero, configuration: config) webView.scrollView.isScrollEnabled = true let html = """ <!doctype html> <html> <head> <meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0"> <style>body,html{height:100%;margin:0;background:#000}iframe{width:100%;height:100%;border:0}</style> </head> <body> <iframe src="https://www.youtube-nocookie.com/embed/videoseries?list=\(playlistID)&controls=1&rel=0&playsinline=1&iv_load_policy=3" frameborder="0" allow="encrypted-media; picture-in-picture; fullscreen" webkit-playsinline allowfullscreen ></iframe> </body> </html> """ webView.loadHTMLString(html, baseURL: nil) return webView } func updateUIView(_ uiView: WKWebView, context: Context) {} } #Preview { ContentView() } Observed behavior: First video plays without issue. Web process crashes when the second video in the playlist starts. Console logs show WebProcessProxy::didClose and repeated memory status messages. Using ProcessAssertion or background activity does not prevent the crash. Only occurs on physical devices; simulators do not reproduce the issue. Questions: Is there something I should change or add in my WKWebView setup or HTML/iframe to prevent the crash when playing the second video in a playlist on physical iOS devices? Is there an officially supported way to limit memory or prevent WebKit from terminating the web process during multi-video playback? Are there recommended patterns for playing YouTube playlists in a WKWebView on iOS without risking crashes? Any tips for debugging or configuring WKWebView to make it more stable for continuous playlist playback? Thanks in advance for any guidance!

Help! Green Video stream from iPhone 17 Pro/Pro Max with WebRTC
I'm at my wit's end with a problem I'm facing while developing an app. The app is designed to send video captured on an iPhone to a browser application for real-time display. While it works on many older iPhone models, whenever I test it on an iPhone 17 Pro or 17 Pro Max, the video displayed in the browser becomes a solid green screen, or a colorful, garbled image that's mostly green. I've been digging into this, and my main suspicion is an encoding failure. It seems the resolution of the ultra-wide and telephoto cameras was significantly increased on the 17 Pro and Pro Max (from 12MP to 48MP), and I think this might be overwhelming the encoder. I'm really hoping someone here has encountered a similar issue or has any suggestions. I'm open to any information or ideas you might have. Please help! Environment Information: WebRTC Library: GoogleWebRTC Version 1.1 (via CocoaPods) Signaling Server: AWS Kinesis Video Streams Problem Occurs on: Model: iPhone18,1, OS: 26.0 Model: iPhone18,1, OS: 26.1 Works Fine on: Many models before iPhone17,5 Model: iPhone18,1, OS: 26.0 Model: iPhone18,3, OS: 26.0

Displaying multiple immersive movies in spheres in an immersive environment
In visionOS, I'm trying to create an immersive environment which would feature several spheres in which immersive movies are visible. I'm starting from a sample code which creates a sphere, sets an immersive movie as its material, and opens it as an immersive environment. This works fine. But if I create a sphere in an open immersive environment using Reality Composer Pro and sets its material to an immersive movie, I can see the movie on the sphere while I move outside of it but if I try to get inside the sphere, it disappears. What would be the right way of doing this ?

On iOS26, in our video playback app(use AVPlayer), the sound and video are out of sync when playing after seeking.
Our app plays TS files on an iPhone. The app fragments the TS files, creates an M3U8 playlist, converts them to HLS(HTTP Live Streaming), and then uses AVPlayer to play the video content. On a device running iOS 26, after starting playback and seeking, restarting playback causes the video and audio to be out of sync (by about 2-3 seconds depending on the situation). This also occurs on iPadOS/macOS 26. This issue was not observed prior to iOS 18. We are trying to fix this issue on the app side, but we have the following questions: The behavior of AVPlayer is different between iOS 26 and previous versions. Has there been any change that could be considered? Or is it a bug? We tried pausing before seeking, but it didn’t seem to have any effect. Are there any APIs or workarounds that can improve this? We would appreciate it if you could tell us any other helpful documents or URLs.

play videos in webM format on iOS Deveices
I would like to play videos in webM format on my iPhone. I understand that it is basically impossible to play videos in webM format on an iPhone, but is there any way to display videos in webM format? I would like to know if there is an official Swift SDK or development kit released by Apple. Or if there are any third-party products, please let me know.

Is it possible to query the TV's current refresh rate?
I'm working on a media app that would like to be able to tell if the TV connected to tvOS is running at 59.94hz or 60.00hz, so it can optimize a video stream. It looks like the best I can currently do is to check if the user has Match Content Rate enabled, and based on that, when calling displayManager.preferredDisplayCriteria to change video modes, I could guess which rate their TV might be in. It's not very ideal, because not all TVs support both of these rates, and my request for 59.94 might end up as 60 and vice versa. I dug around and can't find any available method in UIScreen to get this info. The odd thing is, the data is right there in currentMode when I look in the debugger, but it seems to be in a private or undocumented class. Is there any way to get at it?

WideFOV - APMP - Stereo
Does anyone have a template of an Apple Projected Media Profile Format Description or a File of a Stereo wideFOV video? Use case I have 2 compatible cameras that I stereo sync and I want to move the projection information from the compatible video to the Spatial video that combines them. Every version I can come up with crashes the AVP and when viewing as Spatial in Tahoe I just get a black screen.

Core Transferable Error
I'm developing an app that uses the SwiftUI .photosPicker modifier to allow the user to open videos from their photos. While many videos successfully load, one video results in the following errors occurring: Error loading com.apple.quicktime-movie: <decode: bad range for [%@] got [offs:100 len:1229 within:0]> Error loading public.movie: <decode: bad range for [%@] got [offs:87 len:1229 within:0]> "The operation couldn’t be completed. (CoreTransferable.TransferableSupportError error 0.)" I was able to isolate the line of code within the Transferable where this occurs to be the following: try FileManager.default.copyItem(at: received.file, to: destination) Is there something that I can do to ensure the app can reliably open any video? The entire transferable struct is as follows: import Foundation import CoreTransferable import UniformTypeIdentifiers struct Video: Transferable { let url: URL let filename: String static var transferRepresentation: some TransferRepresentation { FileRepresentation(contentType: .mpeg4Movie) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } FileRepresentation(contentType: .quickTimeMovie) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } FileRepresentation(contentType: .avi) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } FileRepresentation(contentType: .mpeg) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } FileRepresentation(contentType: .mpeg2Video) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } FileRepresentation(contentType: .video) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } FileRepresentation(contentType: .movie) { video in SentTransferredFile(video.url) } importing: { received in try Video.transfer(from: received) } } static func transfer(from received: ReceivedTransferredFile) throws -> Video { let destination = FileManager.default.temporaryDirectory.appendingPathComponent(received.file.lastPathComponent) if FileManager.default.fileExists(atPath: destination.path) { try FileManager.default.removeItem(at: destination) } try FileManager.default.copyItem(at: received.file, to: destination) return Video(url: destination, filename: received.file.lastPathComponent) } }

RealityKit VideoMaterial renders pink on iOS 18
our app is live, and it appears that since the ios 18 update - the VideoMaterial renders pink / purple color instead of the video (picture attached). the audio is rendered properly. we found that it occurs on old devices: iPhone 11 & iPhone SE 2020. I've found this thread of Andy Jazz on stackoverflow: Steps to Reproduce: Create a plane for the video screen. Apply a VideoMaterial using AVPlayerItem. Anchor the model entity to an ARImageAnchor. Expected Outcome: The video should play as a material on the plane in RealityKit. Actual Outcome: On iOS 18, the plane appears pink, indicating the VideoMaterial isn’t applied. What I’ve Tried: -Verified the video URL is correct. -Checked that the AVPlayerItem and VideoMaterial are initialised correctly. -Ensured the AVPlayer is playing the video. I also tried different formats (mov / mp4 / m4v), and verifying that the video's status is readyToPlay. any suggestions?
