iOS 14 users can change the default email app. What effect, if any, does this have on MFMailComposeViewController? Currently if canSendMail() returns false I instruct the user to set up an account in the Mail app. Maybe the wording needs to be different?

Given an Apple Music trackId is it possible to query the user’s media library to see if they’ve added it to their library? Something like: let predicate = MPMediaPropertyPredicate(value: "1440818675", forProperty: MPMediaItemPropertyPersistentID) let query = MPMediaQuery(filterPredicates: Set([predicate])) let songs = query.items let isInLibrary = !songs.isEmpty

In iOS 17 when you search Spotlight for Notes you can see it has an App Shortcut titled New Note that simply opens the Notes app and starts composing a new note. When you open the Shortcuts app, create a new shortcut, search for and tap Notes, notice the New Note action is ONLY included at the top - it's not in the list of actions underneath. There is another intent in the list titled Create Note which will create a new note using the content you specify without opening the Notes app. I want to achieve this same thing in my app - an App Shortcut to open the app and start creating a new item, and a shortcut action to create a new item without opening the app. How can this be done? So far I have created two AppIntents, NewItem and CreateItem. My AppShortcutsProvider only includes NewItem. This works great when searching for my app in Spotlight. But when I open Shortcuts and go to add an action from my app to a shortcut, it includes Add Item at the top as an App Shortcut but also in the actions list underneath. Create Item is included in the list as well which is confusing. I don't want Add Item to be an available action because it's fairly useless to open the app and start creating an item, instead they should use Create Item to create an item in the background. Do I need to instead create a single shortcut that behaves differently in Spotlight vs Shortcuts, is that possible?

I have an app that edits photos in your library. When I call try CIContext().writeHEIFRepresentation(of: editedImage, to: fileURL, format: .RGBA8, colorSpace: originalImage.colorSpace!) The following is logged to the console: writeImageAtIndex:1012: ⭕️ ERROR: 'App' is trying to save an opaque image (5712x4284) with 'AlphaLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. What does that mean and how can I resolve it? Xcode Version 16.0 (16A242d) iOS 18.1 (22B82)

We are creating a watch party app that allows you to video chat with your friends and play a YouTube video at the same time. The video is played using Google's youtube-ios-player-helperlibrary which uses a WKWebView with their iframe API, as that's the only way to play it without violating the Terms of Service. We need the ability to change the volume of the YouTube video separately from the video chat, so you can hear your friends over the video for example. Unfortunately it's not possible to directly change the volume because iOS does not support changing the volume via JavaScript - https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Device-SpecificConsiderations/Device-SpecificConsiderations.html#//apple_ref/doc/uid/TP40009523-CH5-SW10, unlike macOS. Setting volume doesn't do anything and getting it always returns 1. Users can change the volume with the hardware buttons but this applies to all audio including the video chat, not just the YouTube video. Someone found a workaround - https://stackoverflow.com/a/37315071/1795356 to get the underlying AVPlayer and change its volume natively. This worked with UIWebView but does not work now that it uses WKWebView. What can be done to change the volume of the YouTube video?

I have shipped an app that utilizes Core Data in CloudKit viaNSPersistentCloudKitContainer. I now want to add a widget that can query for the current data to display. It's my understanding you need to migrate this to a new location available to a shared App Group. How do you do this? container = NSPersistentCloudKitContainer(name: "AppName") container.loadPersistentStores { description, error in //handle error } container.viewContext.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy container.viewContext.automaticallyMergesChangesFromParent = true

I have a UIViewController that initially does not display any scrollable content, but later on I add a child view controller that does scroll - a UIHostingController whose rootView is a GeometryReader containing a ScrollView. The problem is when you scroll the UINavigationBar remains transparent I’m sure because it couldn’t find a scroll view in the view hierarchy. There is an API to specify which scroll view to use but that’s a UIScrollView. How can I tell it about my SwiftUI scroll view? viewController.setContentScrollView(scrollView, for: .bottom)

I set iOS 26 to install overnight, put my iPhone 16 Pro on the MagSafe charger, watched it charge just fine, and went to sleep. When I woke up the iPhone showed the “plug into power” dead battery screen. I took it off MagSafe and put it back on. A half hour later the phone was warm but still wouldn’t power on, just showed the battery screen with a little red in it. I took it off MagSafe and plugged it into my iPad charging brick with USB cable to give it more power, still it did not turn on. I tried holding all the buttons to try to force a restart but didn’t work. For anyone else encountering this, do this to enter DFU mode and restore it. I had to do it a few times before I got the timing right. Plug into your Mac and open Finder (or apparently a PC with Apple Devices or iTunes) Press and quickly release volume up Press and quickly release volume down Press and hold right side button When the battery disappears and screen goes black, hold volume down and continue holding side button After a couple seconds release the side button and continue holding volume down A prompt to allow connecting to the iPhone should appear after a couple seconds, click Allow, and it’ll say the iPhone entered DFU mode - proceed to restore the firmware

I have an accessoryCircular Lock Screen widget built for iOS 16: ZStack { AccessoryWidgetBackground() VStack { Text("MON") .font(.caption) Text("6") .font(.title) } } When run on iOS 17 it renders an error “Please adopt containerBackground API”. So I changed it to: VStack { Text("MON") .font(.caption) Text("6") .font(.title) } .containerBackground(for: .widget) { AccessoryWidgetBackground() } This causes the error to go away but the circular background is no longer visible (tested with iPadOS 17b2). What’s the right way to implement this?

I have an app that uses NSPersistentCloudKitContainer and a widget that displays a record. I want to add a button with interactive widgets in iOS 17 to modify the visible record via an AppIntent. When I do this the app logs: CoreData: debug: CoreData+CloudKit: -[NSCloudKitMirroringDelegate managedObjectContextSaved:](2945): <NSCloudKitMirroringDelegate: 0x2818002a0>: Observed context save: <NSPersistentStoreCoordinator: 0x280a05180> - <NSManagedObjectContext: 0x281a00410> It does not automatically sync this change to iCloud, not until I manually return the app to the foreground, even if I delay returning from the perform() function. Is there a way to sync NSPersistentCloudKitContainer while the app is in the background as a result of this change triggered in the widget? Thanks!

In my app I get a UIImage for a PHAsset via PHImageManager.requestImage(for:targetSize:contentMode:options:resultHandler:). I directly display that image in a UIImageView that has preferredImageDynamicRange set to .high. The problem is I do not see the high dynamic range. I see the HDRDemo23 sample code uses PhotosPicker to get a UIImage from Data through UIImageReader whose config enables prefersHighDynamicRange. Is there a way to support HDR when using the Photos APIs to request display images? And is there support for PHLivePhoto displayed in PHLivePhotoView retrieved via PHImageManager.requestLivePhoto?

With UIKit you can open a window via drag and drop by creating a UIDragItem with an NSItemProvider and NSUserActivity object in a collection view. Is there a similar SwiftUI API to open a window by dragging out a view from a grid? Or can we only manually invoke openWindow from a button?

Is it possible to sort the user library assets by date captured? The Photos app in iOS 18 lets you choose between Date Captured and Recently Added and I want to offer that same choice in my app. This seems to always sort them by creation date (which I believe is the same as recently added): let assetCollection = PHAssetCollection.fetchAssetCollections(with: .smartAlbum, subtype: .smartAlbumUserLibrary, options: nil).firstObject! let fetchResult = PHAsset.fetchAssets(in: assetCollection, options: PHFetchOptions.imageMediaType())

I’m looking into building a closed source XCFramework from a local Swift package that has dependencies on other packages, which can later be distributed via Swift Package Manager. In initial discussions, we thought xcodebuild does not support linking the dependencies externally, it always includes them statically in the built framework. It's my understanding this is because we're asking xcodebuild to build a framework from a local Swift Package. Is there another way this can be achieved? To explain in more detail: I have built a closed source SDK for other developers to integrate in their apps, currently distributed as an XCFramework. The interesting thing about the SDK is it has dependencies on other libraries, which need to be resolved when adding this SDK as a dependency to an app. The SDK’s dependencies should not be baked into our XCFramework. CocoaPods has worked well for that but we want to instead use SPM. The current project setup is an iOS framework Xcode project and an app Xcode workspace. The framework project is included in the app workspace and is in the same repo as the app, which allows me to modify the framework source code then run the app to test it. The framework project can also be opened independently and built to verify it doesn’t have any errors, but to verify it’s working I run it with the app. To distribute a new release I use xcodebuild to create an XCFramework and then deploy that. For this to work with CocoaPods I had to add a Podfile to the app directly as well as the framework directory so both have the dependencies available. This means I have an xcworkspace for the framework and not just a xcodeproj. I specify the framework workspace file in the xcodebuild command. To switch to a setup that utilizes Swift Package Manager, I created a Package.swift in the iOS framework project’s directory that specifies its dependencies, removed CocoaPods integration including deleting the workspace file, removed the framework project from the app’s workspace, added the Package as a local package to the app project, and added the framework directory via + > Add Files to “App” which adds the package to the top of the sidebar, making its source code available to edit within the app workspace. Everything is working when I run the app. Xcode properly resolves the dependencies for the local package and I can run the app to develop it. Now to create an XCFramework I run the following command in the framework directory (which contains the Package.swift): xcodebuild archive -workspace . -scheme FrameworkName -configuration Release -destination 'generic/platform=iOS' -archivePath './build/FrameworkName.framework-iphoneos.xcarchive' SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES ENABLE_USER_SCRIPT_SANDBOXING=NO This succeeds however the dependencies have been linked statically thus included in our SDK. We need to only include the code from our framework and link to external dependencies, like it does with our current CocoaPods setup. I'm wondering what options there are to achieve this. Even if I need to change the project setup locally, for example to continue using a framework project/workspace instead of a local Swift package. It seems I just need xcodebuild to be able to create an XCFramework which can then be distributed with its own Package.swift file that specifies its dependencies. If it's not possible to link the dependencies externally, could you help me to understand the implications of including them statically? I don't know what problems could arise as a result of that or other concerns this would bring. Thanks!

I've created a closed source iOS SDK from a local Swift package, which has dependencies on other Swift packages, and successfully created a binary XCFramework following the solution from my previous post. I would now like to create a Package.swift to vend this XCFramework and test it in an example app to verify it works as expected before I upload it to a public repo for distribution. I understand that binaryTarget does not support dependencies so we need to use a wrapper. I created a directory containing the following: Package.swift MyFramework.xcframework/ MyFrameworkWrapper/ ├─ dummy.swift Package.swift contains: // swift-tools-version: 5.10 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "MyFramework", platforms: [ .iOS(.v14) ], products: [ .library( name: "MyFramework", targets: ["MyFramework", "MyFrameworkWrapper"] ) ], dependencies: [ .package(url: "https://github.com/gordontucker/FittedSheets.git", from: "2.6.1") ], targets: [ .target( name: "MyFrameworkWrapper", dependencies: [ "FittedSheets" ], path: "MyFrameworkWrapper" ), .binaryTarget( name: "MyFramework", path: "MyFramework.xcframework" ) ] ) I created a new iOS app, selected the project, Package Dependencies > + > Add Local, and added the directory containing this Package.swift. Xcode resolves the dependencies and lists them in the sidebar. I added code to import and use the framework. It builds successfully but the app crashes when run: dyld[63959]: Library not loaded: @rpath/FittedSheets.framework/FittedSheets Referenced from: <7DE247FC-DAFF-3946-AD21-E80F5AF841C9> /Users/Jordan/Library/Developer/Xcode/DerivedData/MyFramework-Example-gaeeymnqzenzrbbmhuebpodqctsz/Build/Products/Debug-iphonesimulator/MyFramework.framework/MyFramework How do I get this working? I'm wondering is my package set up properly to vend the framework specifying its dependencies, and is my XCFramework created correctly? The Package.swift for the framework's source code contains: // swift-tools-version: 5.10 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "MyFramework", platforms: [ .iOS(.v14) ], products: [ .library( name: "MyFramework", type: .dynamic, targets: ["MyFramework"] ) ], dependencies: [ .package(url: "https://github.com/gordontucker/FittedSheets.git", from: "2.6.1") ], targets: [ .target( name: "MyFramework", dependencies: [ "FittedSheets" ], path: "Sources" ) ] ) And I created the XCFramework following the steps in that previous thread: Create archive from package via xcodebuild archive -workspace "$PACKAGE_PATH" -scheme "$FRAMEWORK_NAME" -destination 'generic/platform=iOS' -archivePath "$ARCHIVE_PATH/iOS" SKIP_INSTALL=NO BUILD_LIBRARY_FOR_DISTRIBUTION=YES ENABLE_USER_SCRIPT_SANDBOXING=NO ENABLE_MODULE_VERIFIER=NO OTHER_SWIFT_FLAGS=-no-verify-emitted-module-interface Create the Modules directory in the framework via mkdir -p "$ARCHIVE_PATH/iOS.xcarchive/Products/usr/local/lib/$FRAMEWORK_NAME.framework/Modules" Copy the Swift interface files into the framework from the build in DerivedData via cp -a "$BUILD_PRODUCTS_PATH/Build/Intermediates.noindex/ArchiveIntermediates/$FRAMEWORK_NAME/BuildProductsPath/Release-iphoneos/$FRAMEWORK_NAME.swiftmodule" "$ARCHIVE_PATH/iOS.xcarchive/Products/usr/local/lib/$FRAMEWORK_NAME.framework/Modules" Repeat 1-3 for iOS Simulator Create an XCFramework via xcodebuild -create-xcframework -framework "$ARCHIVE_PATH/iOS.xcarchive/Products/usr/local/lib/$FRAMEWORK_NAME.framework" -framework "$ARCHIVE_PATH/iOS_Simulator.xcarchive/Products/usr/local/lib/$FRAMEWORK_NAME.framework" -output "$ARCHIVE_PATH/$FRAMEWORK_NAME.xcframework"
