I've noticed issues with logging in the Mac's console app for a very long time now (from Xcode 15?) but have just spent several hours trying to objectively observe and monitor what's going on and try to set up reliable logging. But I've totally been unable to and my conclusion is that logging just absolutely cannot be relied upon at all, its so chronically bad as to be unusable. If I for example add some logging lines right at the start of didFinishLaunchingWithOptions() and use a variety of logging mechanisms NSLog(), print(),os_log_with_type(), OSLog() (AppDelegate is in Obj-C and calls Obj-C logging, then calls a swift function for Swift logging), then none of them are reliable. If the app is build/installed via Xcode then logging is reliable within Xcode's console and also within the Mac's console app. But then if the app is uploaded/installed via Testflight it's a very different matter. Sometimes, but not very often, the logging is as expected, but more often than not, some of it is missing. How much is missing seems totally random, sometimes its a little, sometimes its a lot, and something else that very very often happens is there's lots of duplicate logging, each logging line will appear 2 or three times. Here's a very simple example to illustrate what happens (in this example for simplicity I'm just showing using NSLog, don't focus on that as I know NSLog is "old", its the exact same result regardless of how the logging is actually performed). - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { appDelegate = self; NSLog(@"Log line 1"); NSLog(@"Log line 2"); NSLog(@"Log line 3"); NSLog(@"Log line 4"); NSLog(@"Log line 5"); When the app is downloaded from Testflight then only very rarely will I see 5 lines of logging, sometimes it'll be 4, sometimes 2, sometimes none. And quite often the logging is duplicated i.e. I might see for example in the Console app: Log line 1 Log line 1 Log line 2 Log line 2 Log line 3 Log line 3 In general it's just totally unusable and unreliable. It just cannot be be used at all. Why is it this bad? What can be done to make logging reliable and useful? I've spent days and days reading the recommended approaches, trying things out, including the new stuff like OSLog etc. But it remains dreadful. What is the recommended approach to make logging 100% reliable? There's never any problem with Xcode's console, it's only with the Mac's console app. However, when an app is being tested which has been installed from Testflight then using Xcode's console can't be used. So If a QA team find problems with a Testflight build and attach the Console log its utterly useless as its contents are effectively random.

We use network extension for the VPN connection implementation. In the network extension, we need to call a third-party library to do some check. Before the macOS is upgraded to 15.2, everything is fine. It just stop working after macOS is upgraded to 15.2. I did some debugging, and looks like the api provided by the dylibs is blocked. One system log is shown suspiciously Unable to create bundle at URL (<private>): unable to create file system representation of URL (13) The background is that we did embed the third-party dylibs in the app resources folder and the app extension tries to dlopen the dylibs and call the functions. And actually we do not know how the dylibs are implemented. Since it was working with older macOS, we would like to see if there is any related change on os itself. I have tried to change the places of dylibs, moving them from container app bundle resource folder to app extension resources folder, even the app group folder. Unfortunately it does not work either. Do you guys have any opinions?

I have shortcuts up and running and I have my custom response added to my completion handler since day1. Recently I upgraded to iOS18, and found out the app I develop can not display the custom response. I test the app on iOS17.6, the display of custom response is no problem. The situation is exactly like the problem posted on 2018: https://forums.developer.apple.com/forums/thread/109324 Can anyone help me or have the same bugs? Thank you so much! Happy 2025

Hello I'd like to be able to rotate an mapkit.ImageAnnotation. From this post on Stack Overflow https://stackoverflow.com/questions/78686475/need-to-style-a-mapkit-js-marker-annotation/78702266#78702266 I understand that it's possible, for example, to the following: map.annotations[0].element.style.cursor = "pointer"; and this works for me. However, I need to do something like the following, but it doesn't work: map.annotations[0].element.style.transform = "rotate(90deg) "; Any ideas how a mapkit.ImageAnnotation and mapkit.MarkerAnnotation can be rotated? Thanks in advance Sam

First of all : Thanks for the great presentation (wwdc2023-10180), Siraj ! This new, simple API looks like what we've been looking for for easy manageable background location updates with 'automatic battery drain minimization' :-) There were two questions that came to my mind. As far as I understood, the CLLocationUpdate.LiveConfiguration is used to help the location services to improve the location fixes. Are there other options planned to specify the granularity of delivered locations e.g., how accurate the locations need to be (as the desiredAccuracy and distanceFilter settings for the olden CLLocationManager)? Does the Implementation switch between significant location changes and regular, more expensive ways (like GPS hardware) or just deliver the most feasible accuracy available at the time of notification? I'm just curious - if I get the most feasible granularity, everything is fine for me anyway :-) Thanks again, Michael

We’ve set up an advanced App Clip experience that successfully launches when a user scans our QR code. However, the same App Clip invocation URL does not launch when tapping the associated Action Link on our Apple Place Card in Apple Maps. Instead of opening the App Clip, the link falls back to the website. What We Have Done So Far: App Clip Launched in App Store Connect: Our App Clip is approved and live on the App Store. Here is the invocation URL: https://appclip.parkzenapp.com/park?q=oJrbSIgx Below is the QR code for our Advanced App Clip experience we are attempting to open in our Apple Maps Place card When scanning the QR code that uses the same App Clip invocation URL, the App Clip reliably launches as expected. Here is our apple-app-site-association file, thats correctly served from the associated domain: https://appclip.parkzenapp.com/.well-known/apple-app-site-association Add here is a screenshot showing how the appclip.parkzenapp.com domain is correctly validated. Advanced App Clip Experience: We created and submitted an advanced App Clip Experience specifically tied to our location on Apple Maps. This App Clip Experience is approved and live. Below is an image of our set up of this Advanced App Clip Experience Business Connect: We've created the Apple Maps Location in business connect and added the advanced App Clip experience invocation URL as an Action Link in the place card. See screenshot below. Apple Maps Place: https://maps.apple.com/place?auid=906421750045811407 Despite meeting these conditions, when a user taps the Action Link (the "Reserve" button in the Apple Maps Place Card), the fallback website opens rather than the App Clip. Question: What additional step or configuration might we be missing to ensure the Action Link on our Apple Maps place card triggers the App Clip instead of the website? Thank you

I'm writing a SwiftUI LDAP Browser. I built a command line swift app to do some testing and it works fine. I had to add the certificates from the LDAP server to the system keychain before it would work with TLS/SSL. Then I ported the same code into a SwiftUI app but I cannot get it to connect via TLS/SSL. On the same machine with the same certs it errors with: An unexpected error occurred: message("Can't contact LDAP server") It connect fine with our TLS/SSL. I suspect this may have to do with App Transport Security. Can anyone point me in the right direction to resolve this? App is MacOS only.

Stripe offers variable payment structures, also known as "irregular recurring payments," which include: Usage-based billing: Charges amounts based on usage during the billing cycle (e.g., minutes used or energy consumed). Quantity-based billing: Charges a pre-agreed amount based on quantity (e.g., number of users in a subscription). Is it possible to implement this type of billing in the Apple Store for apps? How would variations in amounts be handled?

In the sandbox environment, when I quickly and repeatedly purchase an item, Transaction.id will be repeated. Will there be duplication in the production environment? func pay(productId: String, orderId: String) async { guard !productId.isEmpty, !orderId.isEmpty else { return } let orderObj = ApplePayOrderModel.init(orderId: orderId, productId: productId) do { let result = try await Product.products(for: [productId]) guard let product = result.first else { return } let purchaseResult = try await product.purchase() switch purchaseResult { case .success(let verification): switch verification { case .verified(let transaction): orderObj.transactionId = String(transaction.id) await transaction.finish() case .unverified(let transaction, let error): await transaction.finish() } case .userCancelled: break case .pending: break @unknown default: break } } catch { print("error \(error.localizedDescription)") } }

​ I developed a Content Filter using the Network Extension, and when deployed to a batch of hosts (50 +), the installation worked for most of them, but there were six exceptions: five of them were macOS 10.15 and one of them was macOS 12.5. ​ The phenomenon of these 6 hosts is: in the System Settings->Network, two content filters with the same name appear. When one of the content filters with the same name is clicked, shows "Please use 'X Agent Extension' to control this content filter configuration" ('X Agent Extension' is the program I developed, this content filter can be deleted by clicking the minus sign in the lower left corner). Click on another content filter with the same name, shows 'Please use 'null' to control this content filter configuration', (but this content filter can't be removed by clicking the minus sign in the bottom left corner). ​ These systems are clean, use CLI 'systemextensionsctl list', and have only one systemextension in the output (this systemextension is my content filter). Online reference "https://forums.macrumors.com/threads/how-to-delete-custom-dns-profile-from-network-preference.2293322/" this paper, by closing the SIP, and delete file '/Library/Preferences/com.apple.networkextension.plist', then restart the system can remove the abnormal content filters with the same name. After restarting the system and reinstalling my content filter, the two content filters with the same name disappear (only the Content Filter I reinstalled) and the exception scenario cannot be repeated. ​ I would like to know, why do I have two content filters with the same name, how can I avoid this phenomenon, is there a way to remove the wrong content filter without closing SIP.

I am trying to get universal links to work in our app Firefox iOS The Problem: I am not able to get universal links to work for our release app or beta app scheme locally or with a TestFlight build. I am able to get it working on our development scheme with a locally hosted app site association file. I also was able to get it working using our development scheme but setting the bundle id to the release app bundle id. I also built a demo app with the release app id and the release app development certificate. It succeeded there as well. Implementation Steps: Added associated domains entitlement to the production and beta schemes for our main app target (No associated domains entitlements or capabilities added for any extensions) Confirmed that the bundle ids associated with these schemes have the associated domains capability Added applinks:blog.mozilla.org to associated domains list Confirmed in code that user activities are being handled via SceneDelegate.swift Steps to Debug: I have gone through and validated every step in the provided Universal Link Debugging. All were successful: Associated Domains Development -> Diagnostics: Opens Installed App Validate AASA host and applinks match curl -v https://blog.mozilla.org/.well-known/apple-app-site-association returns the expected json file swcutil dl correctly downloads the AASA blob swcutil verify succeeds I have inspected the IPA of our beta build and confirmed the App ID and the associated domains is an entitlement. I have looked at the console logs filtering by swcd. I am not seeing any errors and I see the download for the AASA file kick off: Beginning data task AASA-4BABF039-3C69-4E36-AA4E-ECCDF3D14878 { domain: bl….mo….org, bytes: 0, route: cdn } There is only one error that appears in the console but our app is not enterprise-managed so I assume this is normal. Error getting enterprise-managed associated domains data. If this device is not enterprise-managed, this is normal: Error Domain=SWCErrorDomain Code=1701 "Failed to get associated domain data from ManagedConfiguration framework." UserInfo={NSDebugDescription=Failed to get associated domain data from ManagedConfiguration framework., Line=298, Function=<private>} I have run Sysdiagnos and identified for our App ID: Site/Fmwk Approval: approved I am at a loss as to what is preventing universal links from working even though all validation steps pass.

Hi, We use the (now deprecated) server-side receipt verification API (*1) with the app we are maintaining and there are some points I would like confirm on how its response changes based on whether the purchase being processed was a subscription that used an offer code or not. I am particularly concerned about the following: Are there any properties of the response that are added or missing? Is there any property indicating that an offer code was used? If there is, which field is that and what values does it take? Are there any special steps or options required when processing the receipt which used an offer code on the server side? *1 https://developer.apple.com/documentation/appstorereceipts/verifyreceipt

Hello, I am currently optimizing the performance of my application. I would like to obtain information about users being killed after leaving the application in the background, in order to evaluate whether the application is running normally in the background. I noticed that there is a Background Termination information in Xcode ->Organizer that records background exits. I would like to know the rules for obtaining this information and what is the health standard for this indicator on the Apple side?

I have my phone set to small icons on home screen, but it sill doesn't show the name of the app like when it is on large icons, please fix or just add names to large icons too so i stop running into this glitch.

We updated the apple-app-site-association file two weeks ago and we are only seeing the new content from Apple's CDN serving certain regions such as Texas and Canada. Regions such as Colorado intermittently sees the old content and California has been receiving the old content all the time. Is this a known issue? If yes, when can we expect this to be fixed and where to check the status? If not, can someone in charge of CDN please look into this? Let me know if there is a better place to report this issue and get the support ASAP though. Thank you in advance and happy new year!

We integrated App Store Server notification, to get notified about CONSUMPTION_REQUESTS and REFUND notifications. In the data, we noticed same transactionId have multiple REFUND decisions, usually REFUND_DECLINED and then REFUND. Why is that? Did user contact customer support ? For the second (or later) REFUND decision, CONSUMPTION_REQUEST notifications are usually not sent, but thats not always the case. Sometimes, REFUND decision are the same. Sometimes, we get even 3 or more REFUND related notifications for same transactionId, e.g: 2024-12-02: REFUND_DECLINED 2024-12-05: REFUND_DECLINED 2024-12-12: REFUND Do user request refund again ? Do they contact customer support ? But I can not explain why sometimes status it REFUND at first, but then later REFUND_DECLINED. Thank you already in advance:)
