Hi, I want to install macOS Catalina on a partition on my computer's hard drive to test and fix some bugs for my Mac app. I can't seem to find a simple way to download the installer. I found a link to the Catalina page on the Mac App Store through some other website, but when I try to download it, I get an error saying "This copy of the macOS Catalina installer application is too old to be opened on this version of macOS". I've checked the Downloads page from the developer page, and it's not listed there either. What gives? Shouldn't be easier to test Mac apps on older versions? FWIW I'm trying this on a MacBook Pro 2016.

Hi, I haven't been able to add some basic SiriKit actions to my macOS app in macOS Monterey. To test this out, I created a new project, made it a macOS app with Storyboard. Then I added an intents definition file, and added a basic intent, with no inputs/outputs. I added the intent name to "Supported Intents" in the target "General" configuration. Now when I build and run the app, the shortcut doesn't show up in the Apple Shortcuts app. I've tried looking for the "Siri" capability in "Signing & Capabilities" and it's not listed there (compared to a new iOS app where it would be). I'm not sure what I'm missing here. Would love some help. I'm using Xcode 13.1 on macOS Monterey RC.

Hi, My Mac app saves it's local database and other important information in the Application Support directory. I want to now create an Intents extension for the app so I can create shortcut actions. When I currently run this, the Application Support directory for the extension is different than for the main application. Is there any way on macOS for the extension to access it's parent applications App Support directory? I know it's not possible in iOS, and you have to use App Groups for this, but I'm wondering about the Mac. BTW, the app is a sandboxed app for the Mac App Store.

I am building a widget for my (AppKit) Mac app, and one thing I can't figure out is how to detect when a Link is pressed in the widget to open the parent app. It just opens the parent app but I can't get any information about the URL that was passed in. With iOS, it's easy to detect, from the AppDelegate method: - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation I can't find anything equivalent on macOS. Can someone point me to the right place?

Hi, When I login to App Store connect, I get a banner message saying "Review the updated Paid Applications Schedule": In order to update your existing apps, create new in-app purchases, and submit new apps to the App Store, the user with the Legal role (Account Holder) must review and accept the Paid Applications Schedule (Schedule 2 to the Apple Developer Program License Agreement) in the Agreements, Tax, and Banking module. When I click the link, select "View and Agree Terms", and select the checkbox and select the "Agree" button to accept the terms, I get an error message: We are currently unable to process your request. Please try again later. This has been happening for the past 2 days now. What should I try to do to overcome this problem? I'll file a bug with Apple, but it takes them many days to respond to these issues usually.

I want to use the "SF Pro Text" font in my app. It works fine when I build my app on my main computer running macOS11 Big Sur, but I have a 2nd partition to run macOS Monterey, and it doesn't seem to be available there at all, whether through Interface Builder or through code (using NSFontManager). Using this returns nil on my Monterey partition: NSFont* regularFont = [[NSFontManager sharedFontManager] fontWithFamily:@"SF Pro Text" traits:NSFontWeightRegular weight:5 size: 16.0]; Maybe I'm missing something here ... should I have to install the font manually? I thought the SF Font is a 'system font', so it would be available on all Macs?

Hi, I have a paid app in the Mac App Store, and I want to verify that the user purchased the app legitimately. Does the StoreKit2 framework have an easy way to determine this? From the documentation I've seen, I believe the 'Transaction.currentEntitlements' call will only return transactions for IAP and subscriptions. I would assume that 'Transaction.all' would work, but when I run the app (with Xcode debugger attached) I get no results. What's the best way to test this out for an app that's going to be paid-up-front?

Hi, I am working on a widget for my existing Mac app. The problem I am running into is that when I add a Link from the widget to the main app, the method 'openURLs' isn't called at all: - (void) application: (NSApplication *)application openURLs:(NSArray<NSURL *> *)urls  So I'm not able to direct the app on how to best handle the widget tap. I'm trying to work around that by trying to detect if a Link was selected. Something like this could work Link("Test", destination: URL(string: "https://duckduckgo.com")!) .environment(\.openURL, OpenURLAction { url in print("---> testing link actioned") return .systemAction }) When I add this to the main app, it works fine. But when I add something like this to the widget, the completion handler isn't called (supposedly). Can someone confirm if this was supposed to work inside a widget? Or is it only something that works from the main app?

Hi, I am trying to invoke this NSApplicationDelegate callback from my Mac app, but it's not getting called: - (void)application:(NSApplication *)application openURLs:(NSArray<NSURL *> *)urls I have registered the URL scheme in my Info.plist: <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleTypeRole</key> <string>Editor</string> <key>CFBundleURLName</key> <string>com.my.testapp</string> <key>CFBundleURLSchemes</key> <array> <string>mytestapp</string> </array> </dict> </array> Now I use a 2nd Mac app to test this out, by invoking the following code: if let url = URL(string: "mytestapp://") {             NSWorkspace.shared.open(url)         } This causes my first app to come to the foreground, and the "applicationDidBecomeActive:(NSNotification *)notification" method gets called, but the "application:(NSApplication *)application openURLs:(NSArray<NSURL *> *)urls" method mentioned above doesn't get invoked, which is what I want. Any ideas about why that might be the case?

Hi, I have a paid app available through the Mac App Store, and when the user opens the app, I want to verify that the transaction of the payment is valid. I would have assumed that in StoreKit2, the 'Transaction.all' would work, but when I tested this, it shows 0 transactions for all users. This is what I'm testing: for await result in Transaction.all { guard case .verified(let transaction) = result else { continue } print("verified product = \(transaction.productID)") // send to analytics } But nothing gets observed in the analytics. Does the StoreKit2 framework have an easy way to determine transactions that are made for paid-up-front apps?

Hi, I am trying to build a Mail 'action' extension, and want to access the email body and parse it for specific content. Not sure how to go about converting the 'rawData' that comes in the MEMessage into something that I can read. Here's how I access the rawData property: func decideAction(for message: MEMessage, completionHandler: @escaping (MEMessageActionDecision?) -> Void) { var action: MEMessageActionDecision? = nil      if let messageData =  message.rawData {          print("messageData = \(messageData)") // what to do here??      } else {          action = MEMessageActionDecision.invokeAgainWithBody      } return action } The documentation just says this is 'unprocessed data': The content is available after MailKit downloads the message. MailKit provides the content as unprocessed data. For details about the format of the data, see RFC 2822. But I'm not sure what I'm supposed to do to go about converting the unprocessed 'data' into something that is accessible and useful to my app. Let me know if you have any thoughts or recommendations

Hi, My app is free-to-download but with an in-app purchase to unlock all the features. A user wants to buy 15 copies of the "unlock" IAP and distribute it to his team, using MDM to distribute it easily. I don't believe there is a way to do this through business purchases, is that right? You can only download apps through MDM but not in-app purchases. So what's the best way to do this? Are there any standard solutions? Can I upload a new version of the app that's "paid up-front" but not available through the regular App Store, but only through MDM?

I'm confused about this ... the MailKit headers files seem to suggest that MailKit APIs are available for iOS16 now. But I haven't seen any documentation mention it, and you can't create a MailKit extension for iOS (using Xcode 14) like you can with macOS. So is it available to use in iOS or not? If so, how do we create an iOS target for the MailKit extension?

Hi, I am getting a crash report from a user, where they get an application crash when they open a CSV file on their device. I use the standard DataFrame(contentsOfCSVFile: fileURL, options: options) initializer to create a DataFrame, but that's where it's crashing, even though it's inside a try-catch block: public func loadInitialCSVData(withURL fileURL: URL) throws -> DataFrame {      let options = CSVReadingOptions(hasHeaderRow: true, delimiter: ",")       do {          let dataFrame = try DataFrame(contentsOfCSVFile: fileURL, options: options) } catch { // log error here - doesn't get here } This is from the crash report: Exception Type: SIGTRAP Exception Codes: TRAP_BRKPT at 0x21e02be38 Crashed Thread: 0 Thread 0 Crashed: 0 TabularData 0x000000021e02be38 __swift_project_boxed_opaque_existential_1 + 9488 1 TabularData 0x000000021e099d64 __swift_memcpy17_8 + 4612 2 TabularData 0x000000021e099958 __swift_memcpy17_8 + 3576 3 TabularData 0x000000021e09935c __swift_memcpy17_8 + 2044 4 Contacts Journal CRM 0x000000010433f614 Contacts_Journal_CRM.CJCSVHeaderMapper.loadInitialCSVData(withURL: Foundation.URL) throws -> TabularData.DataFrame (CJCSVHeaderMapper.swift:26) 5 Contacts Journal CRM 0x00000001043009d8 (extension in Contacts_Journal_CRM):__C.MacContactsViewController.handleSelectedCSVFileForURL(selectedURL: Foundation.URL) -> () (MacContactsViewControllerExtension.swift:28) 6 Contacts Journal CRM 0x0000000104301e64 @objc (extension in Contacts_Journal_CRM):__C.MacContactsViewController.handleSelectedCSVFileForURL(selectedURL: Foundation.URL) -> () (<compiler-generated>:0) 7 Contacts Journal CRM 0x0000000104222c94 __51-[MacContactsViewController importCSVFileSelected:]_block_invoke (MacContactsViewController.m:954) 8 AppKit 0x00000001bbe8f294 -[NSSavePanel didEndPanelWithReturnCode:] + 84` I can't diagnose the crash, because it doesn't have more information. I don't have access to the CSV file currently either, so I don't know what else I can do to prevent it. What could possibly be causing this crash? Does it not matter that I am also trying to catch the errors it's throwing, or can the app crash because of some internal reasons with the framework?

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.
