Hi, I want to work with some of the new iOS16 APIs while maintaining backward compatibility with iOS15 as well as Xcode 13. I'm running into a problem here that I can't seem to store the new iOS16 API as a property of an existing class. For e.g. I'm interested in using the new DataScannerViewController and want to store it as a property so I can reference it when scanning. If I declare it in my ViewController: var dataScanner: DataScannerViewController? it won't compile with Xcode13. I can't seem to also mark this with @available or #available(iOS 16) either: if #available(iOS 16, *) {         var dataScanner: DataScannerViewController? } What's the best way to handle this? In Objective-C, we could use __IPHONE_OS_VERSION_MIN_REQUIRED or something to that effect to avoid this problem, but I'm not sure what the best Swift solution is.

Hi, Is DataScannerViewController available to be called directly from Objective-C? I see the header file has an "objc" attribute on it, but trying to initialize it from an Objective-C file doesn't seem to be working for me. Maybe it's something I'm doing wrong, but I wanted to first clarify and confirm that if it indeed possible to use it directly in Objective-C, or not?

Hi, With StoreKit2 giving us the up-to-date subscription status using Transaction.currentEntitlements, is there any value in storing the status separately in keychain as well? Or will that just add an unnecessary layer to manage (and possibly mess up)? I just want to subscription status to know if I need to unlock certain features in the app or not, and wondering if just looking at currentEntitlements and saving that in my Store object is enough. Thanks.

I recently had to make a change to my Mac app where I need to add a special "Contact Notes" entitlement, so that means that I can't rely on "Automatic Code Signing" anymore. So here are the steps I took to build and distribute the app with manual code signing: from "Certificates, Identifiers & Profiles" from the Developer, I added entitlement to my app identifier, and then created new manual provisioning profiles (one for "macOS App Development" under Development, and one for "Mac App Store" under Distribution) in Xcode, added the entitlement to the Entitlements files in Xcode, in Signing & Capabilities, unselected the checkbox for "Automatically manage signing", and under "Provisioning Profile", for both Debug and Release builds, I chose to import the new provisioning profiles that were created I can build and run in debug mode, and it works fine. I then created an 'archive' of the app, which also built fine, and opened up Organizer. In Organizer, I choose the "Distribute" button, select "App Store Connect" as the distribution method, and choose "Upload" as the destination. After it prepares the archive, it shows the usual two checkboxes for "upload app symbols" and "manage version and build number", and I select Next. Till now, everything works as expected. Now I get the "Select certificates and Mac App Store profiles" page ... here, for the dropdowns for my app's targets, I select the correct provisioning profiles. BUT .. the "Next" button never next gets enabled, so I can't move forward! There's no error message, or anything in Console that makes sense to me. But I just can't seem to be able to select "Next" to the final step before uploading the build to App Store Connect. When I went back and selected "Automatically manage signing" again, and build and archive, the new archive doesn't have this step again, so it works fine and goes to the final upload page. What can I do to find out the issue that's causing this page to not validate? Can I upload the archive build through some other way (like from Terminal) that might give more information? NEVERMIND: turns out, I needed to "Mac Installer Distribution" Certificate, which I generated from the dropbox.

I want to test my UNUserNotificationCenter authorization workflow for my MacOS app. I can't seem to find a way to reset the authorization status to notDetermined again. tccutil doesn't seem to contain any options for this. Any suggestions?

Hi, I plan to use the new AppTransaction.shared API in StoreKit2 to find the user's original purchase date and version for my macOS app. However, when testing this running in the debugger, the app shows up with an App Store login prompt, asking for my login and password, which is undesirable. I wanted to know if this is just a sandbox quirk, or is the "AppTransaction.shared" API supposed to trigger this prompt for all users, even in production? In that case, is it like the old "Refresh receipt" API where we shouldn't trigger this automatically when a user opens the app, and instead have a button somewhere that triggers the call? 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, Is there a way to take a screenshot of just your widget, in code or even some user action? 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 am testing out an update for my app in macOS Sonoma. I first installed the App Store version of my app on the device running macOS Sonoma, and it ran fine. I then installed an updated version of my app through TestFlight (built with macOS Ventura SDK), but when I run this updated version, I get prompted ”MyApp differs from previously opened versions. Are you sure you want to open it?". Why is this happening? Is this warning only because the app is updated through TestFlight, or do I need to do something to prevent this warning from happening when I update my app through the App Store? I see this mentioned in an Apple security update:: App Sandbox now associates your macOS app with its sandbox container using its code signature. The operating system asks the person using your app to grant permission if it tries to access a sandbox container associated with a different app. For more information, see Accessing files from the macOS App Sandbox. My app is already sandboxed, and I'm not trying to access a different app's sandbox container, just my own. For the TestFlight build, it probably also uses the same Release configuration that the App Store build uses. I might have changed my provisioning profiles recently because they expired. Would that affect this and cause a prompt to be showed? Would love to know more about this prompt and how to avoid it. Thanks.

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?

Hi, I have a CloudKit based app in production on the App Store for the past 5 years. One feature in the app downloads a lot of records, over a few different recordTypes, from a user's private database using an array of CKQueryOperations (using an NSOperationQueue). This has been working fine for the past few years, and even now works fine for most users, but an increasing number of users are seeing one of the operations in the array fail for CKErrorServerRejectedRequest. This has been happening over a few weeks now, and the customer support is getting burdensome. Asking the user to repeat the feature sometimes fails, and sometimes succeeds, with no obvious reason. This is also happening for operations for recordTypes where there aren't any records in the private database, as well as for recordTypes where there are hundreds of records. I haven't made any changes over the past year that directly impacts this process. Why would this sudden increase be happening and how do I go about analyzing and fixing it? Also, my current code handles this by cancelling all the operations in the operation queue, because the comment I saw in CKError.h for this error says "This is a non-recoverable error". I'm not sure I completely understand what that means ... is the operation non-recoverable (and hence I should retry by creating a new operation), or is the user's private database corrupted, or what? Would be great if I could get some insight / suggestions.

I am running into an exception whenever I try to open the app's window in visionOS simulator. The exception error message says: "Thread 1: "Error in UIKit client: window visibility must match its layer visibility!"" This is the same code that runs just fine on iOS where I setup the app's window and tab bar controller in code: - (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Setup the UI - Override point for customization after app launch UIWindowScene *firstScene = (UIWindowScene *) [[[[UIApplication sharedApplication] connectedScenes] allObjects] firstObject]; self.mainWindow = [[UIWindow alloc] initWithWindowScene:firstScene]; self.mainWindow.backgroundColor = [UIColor systemBackgroundColor]; self.tabController = [[UITabBarController alloc] init]; [self.tabController definesPresentationContext]; self.mainWindow.rootViewController = self.tabController; [self.mainWindow makeKeyAndVisible]; // setup the tab bar later The exception comes from the makeKeyAndVisible line. I'm not sure what I need to do differently for a visionOS app to make it work. I'm using Xcode 15.1 Beta 2.

Hi, My app has been receiving a huge increase in the number of CKHTTPStatus=503 errors over the past couple of months. I created a thread before, and also a Feedback (FB13300807) over a month ago, but I haven't gotten any assistance on this, and am wondering if there is any better way to get the attention of a CloudKit engineer who might be able to help. From my users, I was able to print out the error code and error userInfo in the console: error.code == 15 (the same as CKErrorServerRejectedRequest), UserInfo={ContainerID=, CKHTTPStatus=503, RequestUUID=17C6B9B9-35DD-411B-8AED-7A497075D228, OperationID=5285362CCD2DDB32}}, CKHTTPStatus=503} How can I get this issue addressed? A lot of users are reporting this issue and it's creating a big support burden.
