On the crash reports, I am getting a lot of crashes with this crash report for two iOS 14 Widgets: Foundation&#9;&#9;_NSFileHandleRaiseOperationException .... SwiftUI&#9;&#9;&#9; FileArchiveWriter.AppendByes(_size:) .... My Widget&#9;&#9;&#9; closure #1 in MyTimelineProver.getTimeline(in:completion:) When checked within the project, this happens in: func getTimeline(in context: Self.Context, completion: @escaping (Timeline<Self.Entry>) -> Void) I have one timeline that asked to update every 5 mins.

New variants of SF Pro were introduced for iOS 16, but I do not see an update to UIFont API to use them. https://developer.apple.com/documentation/uikit/uifont Another thread on here specified that it could be done through UIFontDescriptor, but it doesn't seem like thee that is the official way. I really wish there is more information on this. I am wanting to use Expanded for my iOS update.

With AVFoundation, how do you set up the new 24MP capture on new iPhone 15 models? I strongly believed it was in videodevice.activeFormat.supportedMaxPhotoDimensions array, but not.

I already have an iOS 17 App Intent that works with a URL: @available(iOS 16, *) struct MyAppIntent: AppIntent { static let title : LocalizedStringResource = "My App Inent" static let openAppWhenRun : Bool = true @MainActor func perform() async throws -> some IntentResult{ await UIApplication.shared.open(URL(string: "myapp://myappintent")!) return .result() } } Now, with iOS 18 and Control Widgets, I want to create a Control Widget button that smply opens the app with the same URL. However UIApplication code is not allowed within extensions. For this, Apple says to use OpenIntent which is shown here: Link Apple Sample Code from the link: import AppIntents struct LaunchAppIntent: OpenIntent { static var title: LocalizedStringResource = "Launch App" @Parameter(title: "Target") var target: LaunchAppEnum } enum LaunchAppEnum: String, AppEnum { case timer case history static var typeDisplayRepresentation = TypeDisplayRepresentation("Productivity Timer's app screens") static var caseDisplayRepresentations = [ LaunchAppEnum.timer : DisplayRepresentation("Timer"), LaunchAppEnum.history : DisplayRepresentation("History") ] } WWDC session video about this does not cover this particular method in detail and also this sample code is a bit confusing. So how can I alter this code to just open the app with a URL?

Eventhough some apps out there figured out how to do proper burst capture that is equal to stock iOS Camera App, there is no official API to do so.Currently I have it where it wil call capturePhoto over and over, which is not fast enough. I've seen some hints floating around that the proper way to do this is using bracketed capture any input on this?Thanks in advance.

With the new camera privacy indicator, there is a new need to pause the session at certain times, ie when the full-screen view is presented over the camera preview. This was the only solution for me: func pauseSession () { self.sessionQueue.async { if self.session.isRunning { self.session.stopRunning() } } } func resumeSession () { self.sessionQueue.async { if !self.session.isRunning { self.session.startRunning() } } } This seems to be an expensive operation that takes time. The issue I seem to have is if pause and resume are called near each other in time, the whole app freezes for about 10 seconds, till going back to being responsive. This is mostly due to it still hasn't finished the last process (whether to stop or start). Is there a solution to this? The native camera app seems to do this fine. If you open it, open the last photo, you can see the green indicator on the top right going off (after becoming orange briefly), meaning the session has paused/stopped. If you swipe down on the photo, the session resumes. If you swipe and let it get canceled, quickly swipe again you can see the session pauses and resumes quickly over and over without any issues.

WWDC23 Platform State of the Union mentioned that Volume shutter buttons to trigger the camera shutter is coming later this year. This was mentioned at 0:30:15. Would anyone know when this will be available?

After the session video, "Build a great Lock Screen camera capture experience", was unclear about the UI. So do developers need to provide a whole new UI in the extension? The main UI cannot be repurposed?

I have the main app that saves preferences to UserDefaults.standard. So I have this one preference that the user is able to toggle - isRawOn UserDefaults.standard.set(self.isRawOn, forKey: "isRawOn") Now, I have LockedCameraCaptureExtension which is required know if that above setting on or off during launch. Also if it's toggled within the extension, the main app should know about it on the next launch. The main app and the extension runs on separate containers and the preferences are not shared due to privacy reasons. Apple mentions of using appContext of CameraCaptureIntent, but not sure how above scenario is possible through that....unless I am missing something. Apple Reference What I have for CameraCaptureIntent: @available(iOS 18, *) struct LaunchMyAppControlIntent: CameraCaptureIntent { typealias AppContext = MyAppContext static let title: LocalizedStringResource = "LaunchMyAppControlIntent" static let description = IntentDescription("Capture photos with MyApp.") @MainActor func perform() async throws -> some IntentResult { .result() } }

I've been using keywords separated by commas WITHOUT spaces.What is the recommended method? WITH or WITHOUT spaces? Or there is no difference?

Using Apple Pencil's Double Tap Gesture within your app, which is not a drawing app, allowed? For example, trigger an action within the app?After reading Apple's Human Interface Guidelines, it still seems to be somewhat ambiguous. Thanks in advance.

I have a child view controller added and its view gets viewSafeAreaInsetsDidChange() called every time a frame change happens. how do I avoid this? So far I am using these: self.viewRespectsSystemMinimumLayoutMargins = false self.view.insetsLayoutMarginsFromSafeArea = false self.view.preservesSuperviewLayoutMargins. = false However, viewSafeAreaInsetsDidChange() is till being called. Is there a way to stop that?

With iOS 18, when you tint Home Screen, the widgets also need to pick up the tint. How do you detect this within SwiftUI? I didn't see WWDC24 sessions addressing this.

Prior to iOS 26, this successfully gave me a modal view with a transparent background: let settingsVC = MySettingsViewController() settingsVC.modalPresentationStyle = .automatic //settingsVC.modalPresentationStyle = .overCurrentContext self.present(settingsVC, animated: true, completion: { } MySettingsViewController: self.view.backgroundColor = UIColor(white: 0, alpha: 0.5) Now in iOS 26, modal view is presented in a opaque grey background.

Is it possible for a widget to be reloaded when the photo library changes? Outside of Widgets, there is PHPhotoLibraryChangeObserver Is it possible to use something similar to update the timeline whenever there is a change in the photo library? TimelineProvider.getTimeline(in:completion:)
