Popping Sound

Hello @leizh007, First, a point of clarification: According to the Apple documentation https://developer.apple.com/documentation/avfoundation/avcapturesession/interruptionreason/videodevicenotavailablewithmultipleforegroundapps?language=objc , this interruption typically occurs when the app is running in a multi-app layout such as Slide Over, Split View, or Picture in Picture — all of which are iPad-only features. Picture in Picture is supported on iPhone as well (FaceTime for example). Now, back to your original question: Why Does AVCaptureSessionInterruptionReasonVideoDeviceNotAvailableWithMultipleForegroundApps Occur on iPhone? Based on what you've mentioned, it sounds like you are receiving this interruption when there are not multiple foreground apps. That should not happen, and so my recommendation is that you file a bug report for this issue using Feedback Assistant if you haven't already. And users have reported that when the above error occurs and causes the camera to go black, restarting th

While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) This sounds like a bug, if shouldFailClosed is false, when the feature fails to come up, all URLs should be allowed. Please file a feedback with repro steps and sysdiagnose.

This tutorial covers essential technologies for implementing games on Apple platforms, including Metal rendering, audio, input, and display APIs. See Port advanced games to Apple platforms See Design advanced games for Apple platforms Inspired by Liquid Glass, I want to add shader effects to my app in SwiftUI, but I'm concerned about performance. How do Metal shaders fit in to the SwiftUI layout/drawing system, and are there any performance pitfalls to watch out for? SwiftUI invokes your shaders during rendering. We recommend Optimize SwiftUI performance with Instruments to understand the performance impact of Metal shaders executed during a SwiftUI rendering pass.

Hello, I have been working on an audio module that plays a specific sound at regular intervals -- similar to a workout timer that alerts the user to switching exercises every few minutes. I'm configuring my audio session like this: let session = AVAudioSession.sharedlnstance() try session.setCategory( .playback, mode: default, options: [.interruptSpokenAudioAndMixWithOthers, duckOthers] ) self.engine.attach(self.player) self.engine.connect(self.player, to: self.engine.outputNode, format: self.audioFormat) try session. setActive(true) I schedule playback using a DispatchQueue (that's what scheduleAudio does): self.scheduleAudio(at: interval.start) { do { try audio.engine.start() audio.node.play() for kue in interval.cues { audio.node.scheduleBuffer(kue.buffer, at: AVAudioTime(hostTime: kue.hostTime)) } } catch { print (Audio activation failed: (error)) } } This works perfectly in the foreground. But once the app goes into the background, the scheduled callback runs, yet the

self.scheduleAudio(at: interval.start) { do { } catch { print (Audio activation failed: (error)) } }

This works perfectly in the foreground. But once the app goes into the background, the scheduled callback runs, yet the audio engine does not start, resulting in 'AVAudioSession.ErrorCode.cannotStartPlaying'. Interestingly, if the app is already playing audio before going to the background, the scheduled sounds continue to play as expected. I have added the required background audio mode to my Info plist file by including the key UlBackgroundModes with the value audio. Is there anything else I should configure? What is the best practice to play periodic audio cues when the app runs in the background? How do apps that do turn-by-turn navigation handle continuous audio playback in the background? Any advice or pointers would be greatly appreciated!

That sounds like a massive problem. Have you raised a Feedback report? If not, please do so at https://feedbackassistant.apple.com/ then post the FB number here. The exact model numbers might be important, so be sure to add specific details.

Hello, This sounds like a Simulator bug and we'd greatly appreciate a bug report. Please send one with the Feedback Assistant.

In iOS 26, UINavigationController has a new property called interactiveContentPopGestureRecognizer and is described as this: The interactive content pop gesture recognizes on the entire content area of the navigation controller in cases that are not covered by the interactive pop gesture recognizer and initiates an interactive pop. This property should only be used to set up failure requirements with it. So I believe now the pop gesture properties are defined as so: interactivePopGestureRecognizer is the swipe from the edge gesture interactiveContentPopGestureRecognizer is the swipe anywhere in the main content gesture So by disabling both gesture recognisers, you should be good to implement your custom swipe gestures. navigationController?.interactivePopGestureRecognizer?.isEnabled = false navigationController?.interactiveContentPopGestureRecognizer?.isEnabled = false
