I am trying to figure out how to programatically install a per-user launchd agent - I have an executable Swift script I wrote and I need macOS to enforce it always be running. I found the SMJobBless sample code which I could play with to see how this works, but it hasn't been updated since it was last built with Xcode 4.6. As you can imagine it doesn't compile in Xcode 10. I was able to get it to build by upgrading to the recommended project settings, increasing the deployment target, and selecting my team for the two targets. Following the ReadMe I need to run ./SMJobBlessUtil.py setreq to configure the Info.plists appropriately. These instructions are out of date but eskimo was kind enough to provide updated instructions here to find the .app url. But when I do this and run the command I receive the following output:MacBook:SMJobBless Jordan$ ./SMJobBlessUtil.py setreq /Users/Jordan/Library/Developer/Xcode/DerivedData/SMJobBless-dffakkidazmiowcishyrborysygm/Build/Products/Debug/SMJobBlessApp.app SMJobBlessApp/SMJobBlessApp-Info.plist SMJobBlessHelper/SMJobBlessHelper-Info.plist Traceback (most recent call last): File "./SMJobBlessUtil.py", line 424, in main() File "./SMJobBlessUtil.py", line 418, in main setreq(appArgs[1], appArgs[2], appArgs[3:]) File "./SMJobBlessUtil.py", line 360, in setreq appToolDict[bundleID] = toolNameToReqMap[bundleID] KeyError: '$(PRODUCT_BUNDLE_IDENTIFIER)'It would seem this python script isn't able to work with the newer project structures, not surprisingly. I wasn't able to find any other information on how to accomplish this task in the modern days. So could you please explain how to go about this? 🙂I have an executable .swift file and a .plist that works when loaded from ~/Library/LaunchAgents/ ready to be added to an existing Xcode project. Thanks!

It was discussed in What's New in Photos APIs at WWDC that we should avoid using NSPredicate for custom fetch options if at all possible for performance purposes. In my app, I'm using NSPredicate to get only images from the user's library. I'm not seeing an API that would allow me to get assets from a specific collection filtered to just images without the use of NSPredicate though. Is there a more efficient way to perform this query that I'm not seeing?let photoLibraryFetchResult = PHAssetCollection.fetchAssetCollections(with: .smartAlbum, subtype: .smartAlbumUserLibrary, options: nil) let assetCollection = photoLibraryFetchResult.firstObject! let fetchOptions = PHFetchOptions() fetchOptions.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.image.rawValue) let fetchResults = PHAsset.fetchAssets(in: assetCollection, options: fetchOptions)

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

Given an MPMediaItem the user selected from MPMediaPickerController or from MPMusicPlayerController.systemMusicPlayer.nowPlayingItem, is it possible to find out if this song is lossless and if it supports Spatial Audio? Thanks!

Our app is not localized but we want to begin the localization process starting with push notifications we are going to integrate. The documentation notes: you can store your message strings in the Localizable.strings file of your app bundle and use the title-loc-key, subtitle-loc-key, and loc-key payload keys to specify which strings you want to display String Catalogs in Xcode 15 supersedes Localizable.strings. How do you support this when using String Catalogs? Do you just manually add a Localizable.xcstrings file to your project then manually add a new entry for your loc-key, and the system will find this string without issue? Or will we need to have a Localizable.strings file too?

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

In order to create a UITextView like that of the Messages app whose height grows to fits its contents (number of lines), I subclassed UITextView and customized the intrinsicContentSize like so: override var intrinsicContentSize: CGSize { var size = super.intrinsicContentSize if size.height == UIView.noIntrinsicMetric { layoutManager.glyphRange(for: textContainer) size.height = layoutManager.usedRect(for: textContainer).height + textContainerInset.top + textContainerInset.bottom } return size } As noted at WWDC, accessing layoutManager will force TextKit 1, we should instead use textLayoutManager. How can this code be migrated to support TextKit 2?

On iPhone, I would like to have a more button at the top right of the navigation bar, a search field in the bottom toolbar, and a plus button to the right of the search field. I've achieved this via the code below. But on iPad they should be in the navigation bar at the trailing edge from left to right: plus, more, search field. Just like the Shortcuts app, if there's not enough horizontal space, the search field should collapse into a button, and with even smaller space the search bar should become full-width under the navigation bar. Right now on iPad the search bar is full width under the navigation bar, more at top right, plus at bottom middle, no matter how big the window is. How can I achieve that? Any way to specify them for the system to more automatically do the right thing, or would I need to check specifically for iPhone vs iPad UIDevice to change the code? struct ContentView: View { @State private var searchText = "" var body: some View { NavigationStack { VStack { Text("Hello, world!") } .navigationTitle("Test App") .searchable(text: $searchText) .toolbar { ToolbarItem { Menu { //... } label: { Label("More", systemImage: "ellipsis") } } DefaultToolbarItem(kind: .search, placement: .bottomBar) ToolbarSpacer(.fixed, placement: .bottomBar) ToolbarItem(placement: .bottomBar) { Button { print("Add tapped") } label: { Label("Add", systemImage: "plus") } } } } } }

Hello! What UIKit API enables you to add a view below the navigation bar and extend the scroll edge effect below it in iOS 26? safeAreaBar is how you do it in SwiftUI but I need to achieve this design in my UIKit app (which has a collection view in a view controller in a navigation controller). struct ContentView: View { let segments = ["First", "Second", "Third"] @State private var selectedSegment = "First" var body: some View { NavigationStack { List(0..<50, id: \.self) { i in Text("Row \(i + 1)") } .safeAreaBar(edge: .top) { Picker("Segment", selection: $selectedSegment) { ForEach(segments, id: \.self) { Text($0) } } .pickerStyle(.segmented) .padding(.horizontal) .padding(.bottom, 8) } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline) } } }

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?

The default cell height is 44pt in iOS 18 and 52pt in iOS 26. I'm trying to reduce the height back to 44pt in one screen that needs to fit as much content on screen as possible. How do you do that when using UIListContentConfiguration? I expected this would do the trick but alas it doesn't reduce the cell height. let cellRegistration = UICollectionView.CellRegistration<UICollectionViewListCell, Item> { cell, indexPath, item in cell.contentConfiguration = { var config = UIListContentConfiguration.valueCell() config.text = "Title" config.secondaryText = "Value" // This only removes horizontal margins, does not change vertical margins config.axesPreservingSuperviewLayoutMargins = [] config.directionalLayoutMargins = .zero return config }() }

How can you distribute an XCFramework via Swift Package Manager when it has dependencies on other Swift packages? We accomplished this with CocoaPods in order to distribute our closed source SDK that has dependencies, but need to migrate to SPM. Note none of the types from the dependencies are used as part of our module’s public interface - usage is purely internal. I’ve made a lot of progress following these steps for a simple example: Create Framework Project Create a new iOS Framework project in Xcode and name it WallpaperKit In the project settings select the target and verify in Build Settings that Build Libraries for Distribution is Yes then set Skip Install to No Create a new UIViewController subclass, name it WallpaperPreviewViewController, make it public, and add some functionality to it to show a UIImageView Add a new Package Dependency in the project settings, for this example we’ll use https://github.com/onevcat/Kingfisher, and specify exact version 8.5.0 Add internal import Kingfisher and use it in WallpaperPreviewViewController to download and show an image from the web Close the WallpaperKit project Create Hosting App Project (this makes it easier to develop the framework functionality and test it in an app with Xcode building both in the same workspace) Create a new iOS app project and name it WallpaperApp Create a new workspace named WallpaperApp Close the WallpaperApp project Drag and drop WallpaperApp.xcodeproj into the workspace’s sidebar Drag and drop WallpaperKit.xcodeproj into the workspace’s sidebar Switch the scheme to WallpaperKit and build Select WallpaperApp project, then with WallpaperApp target selected, in the General tab under Frameworks, Libraries, and Embedded Content, click + and add WallpaperKit.framework In ViewController.swift, import WallpaperKit and add functionality to present an instance of WallpaperPreviewViewController Run the app and verify it works Create XCFramework In Terminal, cd into WallpaperKit and run xcodebuild archive -scheme WallpaperKit -configuration Release -destination 'generic/platform=iOS' -archivePath './build/WallpaperKit.framework-iphoneos.xcarchive' SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES DEFINES_MODULE=YES Run xcodebuild archive -scheme WallpaperKit -configuration Release -destination 'generic/platform=iOS Simulator' -archivePath './build/WallpaperKit.framework-iphonesimulator.xcarchive' SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES DEFINES_MODULE=YES Run xcodebuild -create-xcframework -framework './build/WallpaperKit.framework-iphonesimulator.xcarchive/Products/Library/Frameworks/WallpaperKit.framework' -framework './build/WallpaperKit.framework-iphoneos.xcarchive/Products/Library/Frameworks/WallpaperKit.framework' -output './build/WallpaperKit.xcframework' Open the build folder and retrieve the XCFramework Create Swift Package Create a new package in Xcode, select Library, and name it WallpaperKitDist Drag and drop WallpaperKit.xcframework into Sources Create a new directory in Sources called WallpaperKitDependencies Create a new Swift file in WallpaperKitDependencies called WallpaperKitDependencies (SPM requires a Swift file to recognize WallpaperKitDependencies as a valid target and fetch dependencies) Open Package.swift and change it to import PackageDescription let package = Package( name: "WallpaperKit", platforms: [ .iOS(.v18) ], products: [ .library( name: "WallpaperKit", targets: ["WallpaperKit", "WallpaperKitDependencies"] ), ], dependencies: [ .package( url: "https://github.com/onevcat/Kingfisher.git", exact: "8.5.0" ) ], targets: [ .binaryTarget( name: "WallpaperKit", path: "./Sources/WallpaperKit.xcframework" ), .target( name: "WallpaperKitDependencies", dependencies: [ "Kingfisher" ], path: "./Sources/WallpaperKitDependencies" ) ] ) Create Test App (to simulate a third-party app using the package) Create a new iOS app project and name it TestApp Add a new Local package selecting the WallpaperKitDist directory that contains Package.swift Import WallpaperKit and use it to present a WallpaperPreviewViewController This works! Though the console logs objc[39953]: Class _TtC10KingfisherP33_6AA794C9C370CDB07604B4D8B99AEAA312BundleFinder is implemented in both /Users/Name/Library/Developer/Xcode/DerivedData/TestApp-capvhjiqxrdgdnbevpkajicnjpcs/Build/Products/Debug-iphonesimulator/WallpaperKit.framework/WallpaperKit (0x100e8bbf8) and /Users/Name/Library/Developer/CoreSimulator/Devices/E0AF13C2-874C-47B9-B864-72AF3E4D5D4B/data/Containers/Bundle/Application/AF32011A-92E7-4E26-9A97-9F0C25C07863/TestApp.app/TestApp.debug.dylib (0x101a543b0). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. I thought using internal import Kingfisher (or @_implementationOnly import Kingfisher) would have resolved this, but seems to make no difference compared to just import Kingfisher. I suspect it might not be an issue as long as the Kingfisher version number specified in the distribution Package.swift matches the version used in the framework project (and the app does not add a different version as a dependency), but not positive. Can these warnings be resolved, or is it not a concern in this setup? Is this the best solution to distribute an XCFramework via Swift Package Manager that has dependencies on other Swift packages for now or is there a better approach? Thanks!

I want to keep an eye on the App Store Connect release notes to find out when builds created with Xcode 26.2 RC will be accepted. I tried to add https://developer.apple.com/help/app-store-connect/release-notes/ to my RSS reeder but the items listed are not the same, it’s the items from the latest news from Apple Developer instead. Can we get an RSS feed please? Seems will be useful to monitor these release notes over time.

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?

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)
