HiI'm trying to use Xcode's "Build With Timing Summary" feature. It kicks off a build, and I can see the new build in the Build Reports navigator, but when I look through All Messages in the build results, there is "Timing Summary" information. It just says "Build Success - <date> - 75 seconds", but there isn't a breakdown of the timing results.My target builds an iOS app with many extensions, so I can't post the whole logs here. But is there any reason why I can't find the timing results? I do have that older Xcode flag 'ShowBuildOperationDuration' which still works, but only gives the same overall build summary time, not a breakdown.

Hi, I've been working with Core Data for a number of years, and I remember that when I needed to add attributes or entities to the data model, I had to first create a new model version, then add the new attributes/entities, and then use the "lightweight migration' flag when adding the NSPersistentStore to the NSPersistentStoreCoordinator. If it didn't add the new model version, the app would crash. I've tried adding something to my data model now after a few years, without adding a new model version in Xcode. And right now, it seems to work fine. I can read/write to the new attribute that I added to an entity, and nothing crashed. I tried this on the simulator, as well as on my device. Did something change at some point, where adding a new model version isn't a requirement for using lightweight migration? Or am I missing something? Why isn't it crashing anymore (and will it crash if I change my model without adding a new model version and ship it to production)? Thanks.

Hi, I am developing a 'framework' for a client so they can embed some of my code into their own custom app. I'm confused a bit about the best option to distribute this. I have created an iOS 'framework' within my Xcode project and added all the necessary files there. Can I just build the framework and send them the build folder for the framework? Or is it better to generate an .xcframework that I read about somewhere? I'm just not completely sure about the benefits for distributing an .xcframework file (which there doesn't seem to be an option to generate from Xcode) over just the .framework folder from the built products? Thanks.

Hi, I am working on distributing a 'framework' I made to a client. The framework itself has a couple of dependencies on a couple of 3rd-party frameworks. Also, I don't want to disclose my source code to the client. So after doing some research, it seems like the best way to do this would be to use Swift Packages, and make it a binary distribution, which would basically wrap a .xcframework (which I would generate with my source code). But I'm confused about the next steps ... how would I go about sharing the 'package' with the client? Would I just zip up the 'package' folder and email it to them, and they can unzip it on their end, and add it to their project by using "Add local package"? Or is there a more elegant way to do this, which doesn't require publishing a package publicly?

I am trying to create a Swift Package for a custom framework I'm building for a client. The framework has a dependency on a couple of 3rd party frameworks. I've read about how even though binary frameworks don't support dependencies directly, there is way to do this with a 'wrapper' target, so this is what I came up with for Package.swift: let package = Package( name: "SBCardScannerFramework", platforms: [ .iOS(.v16) ], products: [ // Products define the executables and libraries a package produces, and make them visible to other packages. .library( name: "SBCardScannerFramework", targets: ["SBCardScannerFramework-Target"]), ], dependencies: [ // Dependencies declare other packages that this package depends on. .package(url: "https://github.com/apple/swift-algorithms.git", from: "1.0.0"), .package(url: "https://github.com/marmelroy/PhoneNumberKit.git", from: "3.3.3") ], targets: [ .target(name: "SBCardScannerFramework-Target", dependencies: [ .target(name: "SBCardScannerFramework", condition: .when(platforms: [.iOS])), .product(name: "Algorithms", package: "swift-algorithms"), .product(name: "PhoneNumberKit", package: "PhoneNumberKit") ] ), .binaryTarget(name: "SBCardScannerFramework", path: "SBCardScannerFramework.xcframework") ] ) This works, and I can add the package to my test project and import the framework and it links against the dependancies as well, and works correctly. The problem is that every time I run the app, it also shows these messages in the Xcode console: objc[845]: Class _TtC14PhoneNumberKitP33_0FE53357E470A64027C8F0CAF7B114C812BundleFinder is implemented in both /private/var/containers/Bundle/Application/EEE0C0A6-4FF5-44BC-B81A-F95401219D32/TestSBCardScannerFrameworkImport.app/Frameworks/SBCardScannerFramework.framework/SBCardScannerFramework (0x100f4aaf0) and /private/var/containers/Bundle/Application/EEE0C0A6-4FF5-44BC-B81A-F95401219D32/TestSBCardScannerFrameworkImport.app/TestSBCardScannerFrameworkImport (0x10069b778). One of the two will be used. Which one is undefined. There's multiple lines for different classes that show the "Class X is implemented in both [.../MyApp.app/Frameworks/MyFramework.frameworkMyFramework/] and [.../MyApp.app/MyApp]". I'm not sure how to avoid this problem, and whether this could cause a problem down the line. The framework that is the basis for this Swift Package is linked against the two dependencies, because I wouldn't be able to build the framework without them. But they also need to be added to the app target (at least, and if I don't, I get a run-time crash when using the PhoneNumberKit initializer. PhoneNumberKit/resource_bundle_accessor.swift:40: Fatal error: unable to find bundle named PhoneNumberKit_PhoneNumberKit Is there a good way to resolve this issue? I'm worried this will could be a problem for the client when they integrate it into their app, and the app is deployed to 1000s of devices.

Hi,My app supports 2 different share extensions, and before iOS13, it was easy to tell them apart, because I would specify this in the Bundle Display Name (CFBundleDisplayName in info.plist). With iOS13, it seems to only show the name of the app for both share extensions, and not the Display Name specified, which will make it confusing to users if they see the same app icon + name in the share sheet.I filed a Radar for this, but it was returned with "Resolution:Investigation complete - Change required from 3rd party" ... but it didn't specify what kind of change to make.Anyone know how to customize the name of the share extension going forward?Thanks.

Hi, Is there a way to take a screenshot of just your widget, in code or even some user action? Thanks.

Hi, My iOS app includes 4 dependencies added through SPM, and a xcframework file from an external source. When I build the iOS app for the visionOS simulator, it works fine, and it runs in the compatibility mode. When I try to build for the new visionOS SDK, I get build errors related to these external dependencies, like "When building for visionOS Simulator, no library for this platform was found ..." How do I remove these dependencies for just the visionOS SDK? Any help would be appreciated. Thanks.

The [[UIScreen mainScreen] scale] API is unavailable for visionOS, but I use it in various places to pass into Apple's drawing APIs ... for e.g.: UIGraphicsBeginImageContextWithOptions(self.size, NO, [[UIScreen mainScreen] scale]); and for generating thumbnails: QLThumbnailGenerationRequest *request = [[QLThumbnailGenerationRequest alloc] initWithFileAtURL:fileURL size:size scale:screenScale representationTypes:QLThumbnailGenerationRequestRepresentationTypeThumbnail]; What would be the best way to get the 'scale' factor in this case, when building for visionOS?

Hi,I saw the WWDC talk on the new Contacts framework, and I had a couple of questions about the identifier property:When users upgrade from iOS8 to iOS9, will their old AddressBook recordIDs still work if we are using the AddressBook framework in the app (i.e. haven't upgraded to using Contacts framework)?Are the new CNContact identifiers consistent across iOS and Mac devices? i.e. if we have the identifier on one device, we can lookup the contact on another device with the same identifier?Can these identifiers change in the lifetime of that contact? This was a problem with AddressBook recordIDs ... if you removed the account and then synced it back again, all the contacts would get a different identifier. Same with restoring the device. Will the CNGroup and CNContainer identifiers also be consistent across devices?Hope someone in the Apple Contacts frameworks team can answer. Thanks.

When I build my iOS app for the visionOS simulator, it works fine, and it runs in the compatibility mode. When I try to build against the new visionOS SDK, I get build errors related to the bridging header: SimpleList-Bridging-Header.h:5:9: error: 'MyFramework/MyFramework.h' file not found #import <MyFramework/MyFramework.h> ^ 1 error generated. :0: error: failed to emit precompiled header '...DerivedData/CJ-bkylkdabwgxlstdympoknglfewum/Build/Intermediates.noindex/PrecompiledHeaders/SimpleList-Bridging-Header-swift_3HAL1I7NW16O7-clang_3RN0BYG6SZHIS.pch' for bridging header '.../SimpleList/Classes/SimpleList-Bridging-Header.h' 2 errors generated. I don't know why it's not finding my framework for the visionOS SDK, while it works fine for the iOS SDK. The framework is included in the project itself (i.e. it's not an external dependency). Any tips?

Hi, I have an existing Mac app that stores some important values in the keychain. I am working on an update for the app, which was working fine while I was testing with debug builds. But when I build the app for Release and test the update using TestFlight, on trying to access the keychain item, I get prompted by the system: "MyApp wants to use your confidential information stored in "SyncSettingsValue" in your keychain" And the user now has to enter their password and click on "Allow", "Always Allow" or Deny. Obviously this is a really bad experience, and clicking on Deny will stop many features for the user. Why is this happening? I've updated the app 100s of times before and I've never had this problem. I don't believe I'm messing around with any certificate or provisioning profile since the last update, which was only a few weeks ago. How do I find out what is causing the problem here? Or is this a TestFlight issue that won't happen to users when they update through the App Store?

I am having some problem with accessing the CLLLocationManager location from my widget. It works fine with Xcode 15 running on a iOS17 simulator. But running it on a iOS17 device gives me an error in the delegate: To access the location manager, I have this class: class WidgetLocationManager: NSObject, CLLocationManagerDelegate { var locationManager: CLLocationManager? private var handler: ((CLLocation?) -> Void)? override init() { super.init() DispatchQueue.main.async { print("WidgetLocationManager: init") self.locationManager = CLLocationManager() if self.locationManager!.authorizationStatus == .notDetermined { print("WidgetLocationManager: init - auth status is Undetermined") } else { print("WidgetLocationManager: init - auth status = \(self.locationManager!.authorizationStatus)") } } } func fetchLocation(handler: @escaping (CLLocation?) -> Void) { self.handler = handler self.locationManager = CLLocationManager() self.locationManager!.delegate = self self.locationManager!.requestLocation() } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { if let lastLocation = locations.last { if (CLLocationCoordinate2DIsValid(lastLocation.coordinate) == true && abs(lastLocation.timestamp.timeIntervalSinceNow) < 60 && lastLocation.horizontalAccuracy < 200.0 && lastLocation.horizontalAccuracy > 0.0) { self.handler!(locations.last!) } } } func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) { print("WidgetLocationManager: locationManager didFailWithError = \(error)") self.handler!(nil) } } When run on device, I get an error: WidgetLocationManager: locationManager didFailWithError = Error Domain=kCLErrorDomain Code=1 "(null)" Code = 1 in CLError is kCLErrorDenied ("Access to location or ranging has been denied by the user") This is despite getting the following output in the init method: WidgetLocationManager: init - auth status = CLAuthorizationStatus(rawValue: 4) The weird thing is that it works fine in the simulator. On device, I've tried deleting and reinstalling the app a couple of times, restarting the device, making sure the privacy setting is correct etc. Also, on the iOS17 device, when I am in the "Add Widget" page, the location manager runs fine in the preview screen, and shows the 'current location' to the user. But as soon as I add the widget to the home screen, it starts giving me this problem where the location can't be found, and I have to display an error message in the widget. I have the following keys in the Info.plist for the widget: NSLocationAlwaysAndWhenInUseUsageDescription NSLocationWhenInUseUsageDescription NSWidgetWantsLocation The app target also has the following keys in the Info.plist: NSLocationWhenInUseUsageDescription NSLocationAlwaysAndWhenInUseUsageDescription Any idea for what I can try to fix this problem? Thanks.

Hi, I need to keep supporting iOS16 for my widgets. I'm having a problem using the iOS17 'containerBackground' API. Ideally I would use a view extension: extension View { func adoptableWidgetBackground(_ color: Color) -> some View { if #available(iOS 17.0, *) { containerBackground(for: .widget) { color } } else { background(color) } } } But this gives an error: Branches have mismatching types 'some View' (result of 'Self.containerBackground(for:alignment:content:)') and 'some View' (result of 'Self.background(_:alignment:)') If I try to use this directly on the 'body' view modifier like this: if #available(iOS 17.0, *) { .containerBackground(for: .widget) { ContainerRelativeShape().fill(Color.init(UIColor.quaternarySystemFill)) } } else { .background(ContainerRelativeShape().fill(Color.init(UIColor.quaternarySystemFill))) } This doesn't work either. Instance member 'containerBackground' cannot be used on type 'View' How do I use this correctly?

Hi, I am getting a linking error when building my app to run against an iOS17 device, using Xcode15. Same project builds and runs fine with Xcode 14 and iOS16. The linking error just says: clang: error: unable to execute command: Segmentation fault: 11 clang: error: linker command failed due to signal (use -v to see invocation) Not sure what I should try to overcome this. I can't run my app on an iOS17 device. It builds, links and runs just fine on a simulator.
