Overview

Recently we have started refactoring some code to use Swift concurrency in Xcode 15.3. As we have added some new async methods and Tasks, new runtime warnings have emerged titled "Known Hang" and several are listed. None of the stack traces listed with these warnings are in areas directly modified but some of the same types/methods called are also called from the modified areas. So I can sort of understand why they are coming up...but they had to have been there before we added the Swift concurrency. Example of a tooltip with the warnings: My first query is: Are these warnings only issued when Swift concurrency is added/applied (as they were not there when using closures and mostly just off the main thread to network calls)? The documentation indicates these can all be suppressed by turning off the Thread Performance Checker BUT I would rather just suppress the few places as we refactor our codebase (as it is quite large). In that way, any new ones may be documented and we can decide to fix them now or later. I have tried to follow the instructions and added an environment variable PERFC_SUPPRESSION_FILE (in the Scheme) with a full path to a file formatted similarly to the example in the documentation. class:NSManagedObjectContext method:-[NSManagedObjectContext save:] My second query is: I have verified that the variable is set by reading it from the ProcessInfo. However, regardless of my settings, the runtime warnings are still presented. I could not find any examples or even any mention of others using this environment variable. I am reaching out with any advice or ideas to try. Has anyone successfully tried this or found an issue/alternative? Help me Mr. Wizard!

I have an app with which users take photos and upload them in batches. It's used often on older devices, in areas with less than ideal network, and for durations of a full workday - so often the device has low power. The current implementation of uploads uses an NSURLSession configured for the foreground, and as a result my users are used to having to keep the app in the foreground while an upload completes. However, these uploads are big and connectivity is often low, so this takes a long time - often users are stuck waiting with the app foregrounded for 15 minutes or so while the upload completes. So, I created a build which uses an NSURLSession configured for the background. In the ideal case, users could start the upload, put the device in their pocket and continue their workday, and the next time they open their device it will be complete. For some users this ideal case has come true. However, for others, the uploads sit in progress for an indeterminate amount of time, making no progress. My suspicion is that this is because the OS is deferring them until a time when network and power is more available. However, my users are using work devices at a work location - reliable power and network might never be available. Being able to background the app and continue working is valuable for these users, but having the upload complete promptly is essential for them. My questions are: Is it true that background configured NSURLSessions will defer network requests when connectivity or power is low, even if discretionary = NO? Is the exact behavior for when requests will be attempted in the background documented? Is there a way to reliably test background configured NSURLSessions in XCode? I've attempted throttling my connection with Charles Proxy, and using my device in Low Power Mode, but I'm unable to reproduce the request stalling behavior my users are experiencing in the wild. Is there a way to create an NSURLSession that will muscle through difficult or inefficient uploads in the background, with the same reliability as a foreground session? If not, what is Apple's recommended approach to situations like mine? I've considered queueing both a background and foreground upload, and cancelling the other once one completes, but this seems disrespectful to the user's resources. Will setting timeoutIntervalForResource to a lower value cause the OS to more aggressively attempt uploads? Or simply to throw an error sooner? I want the OS to give the upload a long time to complete, but I also want it to attempt it right away. Thanks for any information!

Hello, I've upgraded Xcode to newest 15.4 and now I cannot edit text in the output console (debugger). The Xcode console (output) does not allow editing text and does not allow any text input anymore. I've seen that this may be related to structured logging. I used to mark things in console output by typing some notes for me when debugging. How to do that? How to make Xcode console allow input like add line break to mark items in my log, or add notes?

I've implemented Apple Archive in the app I'm working on and have implemented lzfse algorithm. The framework is extremely impressive in terms of the speed and compression ratios. I'm using the closure in ArchiveStream.writeDirectoryContents to indicate what the current file is being processed, but there doesn't seem to be a way to pull out progress % on each file. I've seen examples here [Accelerate].(https://developer.apple.com/documentation/accelerate/compressing_and_decompressing_files_with_stream_compression) but these aren't using the Apple Archive Framework... I'd really like to stick with the Apple Archive Framework if possible as it's simple and very fast.

inapp purchase product has been in review for more than 24 hours, although we have another product that was submited for review after the first one and it has been approved already

Hi, I am developing Cordova apps/games with in-app purchase products as well as an initial product as non-paid (Free) tier: New users will be able to play freely for a set of games as default at the beginning. Then, if they would like to have more games with different set of attributes or themes, they can add more games with in-app purchases. It is similar to a game called Subway Surfers in App Store I would play in the past. A new player initiates games as Free Tier. After, let us say 3 games, the user is asked if he/she would like to have more games to play with different scenes/themes in different Tiers, in addition to their disposal: Tier 1, Tier 2 and Tier 3. For example Tier 1 adds 3 more games into the Free Tier games so they can play 6 games in the set;Tier 2 add 6 more games and so 9 games they can play and so on. Each individual game in their set is a variant of others in differing Tiers. If they don't wish and play Free Tier games, they may play them too, with limited set of themes but infinite times. If a user chooses a tier, let us say Tier 1, and when they play 6 games, they are asked if they would like advance to Tier 2 or Tier 3. If they choose Tier 2, as they complete the respective games they will be asked for Tier 3. However, if they don't wish to advance, again they can play current Tier games as many times as they wish. It is like non-subscription apps then converted to subscription-based ones. In App Store Connect, I created a number of products for in-app purchases for an app. How I can deliver this Free Tier games in the app and let users try it and allow them to choose in-app purchase products available in AppStore Connect. I would appreciate response and support. Best Lexxyacc

Hi there -- I'm cleaning up the accessibility in our app and making sure it adheres to Apple's suggested guidelines. For accessibilityHint, apple lists a couple of suggestions in the doc here: https://developer.apple.com/documentation/objectivec/nsobject/1615093-accessibilityhint Notably this one is one that I'm having to change a lot in our app: Don’t include the action type in the hint. For example, don't create hints like “Tap to play the song” or “Tapping plays the song.” However, we have some buttons that do different actions based on a double or triple tap in VoiceOver, so our hint looks something like: "Double tap to do X, Triple Tap to do Y" This violates the accessibilityHint guidelines, but I feel like changing this would mean the customer loses out on valuable information. What does apple suggest we do in this case? Thanks in advance!

hello, has anyone seen a feature in the Callkit SDK where one can add an audio input (such as from an MP3 file) into an ongoing voice call? e.g. mix a playing audio file into the microphone audio (or, possibly, mix it to one channel like MP3 file gain = 1 (max), mic = 0) so the audio only comes from the MP3 file?

I'm trying to get the same path you'd get by running getconf DARWIN_USER_CACHE_DIR in the terminal, but via FileManager.default.urls(for: , in:) , but can't really find out how is there a way to do that other than running the shell script via swift?

This issue is a bit strange. On one machine at work, attempting to use the Xcode 15.0 CarPlay simulator results in devices saying "Accessory Not Supported". The redesigned 15.3 simulator crashes on launch. We have tried 5 different phones with USB C, Lightning to USB C, Lighting to USB A, etc and the same result occurs on all of the above. Taking the same phones and cables to 4 other laptops works fine. The non functioning machine connects to any other USB device just fine. We even tried different partitions, installing Xcode, different macOS versions, etc. There are some suspicious parts of the log on the non working machine: default 09:18:10.075726-0400 mobileactivationd Client certification requested by CarPlay Simulator error 09:18:10.088862-0400 CarPlay Simulator Failed to obtain valid certificates from server: <private> error 09:18:10.103753-0400 CarPlay Simulator Incoming message ID 0xaa04 AuthenticationFailed and error 09:18:09.452387-0400 CarPlaySimulatorDeviceLink RemotePairing.framework is not available. default 09:18:09.452419-0400 CarPlaySimulatorDeviceLink RemotePairing.framework not found. Meanwhile the working machines according to Activity Monitor is loading /Library/Apple/System/Library/PrivateFrameworks/RemotePairing.framework/Versions/A/RemotePairing just fine. The non working machine does have that file on disk, so that's not the issue. The non working machine is a 2019 i9 16" MBP. Working machines include a 2018 i7 13" MBP, 2021 M1 Max 16" MBP, and 2020 M1 13" MBP.

Gents, dev(il)s, I am looking for a piece of code or principal explanation to realise following: I have a array of struct Item{} Each item has child [Item] in the content view I would like to have a hierarchical displayed tree of my Items and for each Item line I would like to have a button to remove it or add a child item for a selected one I tired List entity, navigation and have no real success. Is anybody there to give me a small guide? Thank you M

I am attempting to use UITextSelectionDisplayInteraction. It basically works, but I'm unsure how the selection handles are supposed to work. The documentation is minimal and the WWDC video (2023 session 10058) doesn't say much either. As the name suggests, it seems that this interaction only displays the cursor, selection background, and handles. As I change the selection, it updates these views. So if I want the user to be able to drag the selection handles I need to implement that, right? OK, so I add a gesture recognizer to each selection handle. But this doesn't seem to do anything, i.e. the gesture recognizer action never seems to be invoked. Maybe I'm doing something wrong - but I'd like to understand what is supposed to happen. Is adding a pan gesture recognizer to each selection handle the right approach? P.S. I wanted to tag this "WWDC2023-10058", but the per-session tags seem to have disappeared. Is this a forum bug, or deliberate?

Hi, I am using macOS Sonoma 14.5 and the latest version of Xcode (15.4). Every time I open Xcode, it asks me to install additional components. I accept, but when it finishes, the same dialog appears again. I've done this multiple times. I also uninstalled and reinstalled Xcode, but no luck. Can you please help me?

Hello fellow developers, We are trying to develop a chatbot application for ios devices using the powers of Oracle Digital Assistant. Main Documentation :- https://docs.oracle.com/en/cloud/paas/digital-assistant/use-chatbot/oracle-ios.html Implementation instructions :- https://blogs.oracle.com/digitalassistant/post/oracle-techexchange-using-the-oracle-ios-sdk-to-integrate-oracle-digital-assistant-in-mobile-applications The point is when we are trying to run the app, we are facing tons of warnings as in below screenshot. Here is the code for the ViewController.swift as below: // // ViewController.swift // ODA_Configure // // Created by Macbook on 15/05/24. // //import UIKit // //class ViewController: UIViewController { // // override func viewDidLoad() { // super.viewDidLoad() // // Do any additional setup after loading the view. // } // // //} // Import the SDK import UIKit import BotClientUISDK public class ViewController: UIViewController { // Declare a global BotsViewController variable in your app view controller class public var chatViewController: BotsViewController? public override func viewDidLoad() { super.viewDidLoad() // Obtain a shared instance of BotsViewController from BotsUIManager chatViewController = BotsUIManager.shared().viewControllerInstance() // Specify the color changes if any in a particular component. Make sure you set all the required colors in BotsProperties before adding the chat view to the view controller. // Add the chatViewController to your navigationController self.navigationController?.pushViewController(chatViewController!, animated: false) // Obtain a shared instance of BotsManager let botsManager = BotsManager.shared() // If you require access to callback methods provided in AuthenticationProvider.

Make sure you set all the feature flag values before passing the botsConfiguration to initConfiguration. chatViewController?.initConfiguration(botsConfiguration: botsConfiguration) // If you require access to callback methods provided in BotsMessageServiceDelegate. Make sure your class conforms to BotsMessageServiceDelegate //botsManager.delegate = self // If you require access to callback methods provided in BotsEventListener. Make sure your class conforms to BotsEventListener //botsManager.botsEventListener = self // Initialize and establish connection to the chat server BotsManager.shared().initialize(botsConfiguration: botsConfiguration, completionHandler: { (connectionStatus, error) in if error != nil { print ("Error: \(String(describing: error?.localizedDescription))") } else { print ("Connection Status: \(connectionStatus)") } }) } } After executing this code, we are getting the message as build succeeded , and this is the emulator, which happens to be blank white all the time. Possibly due the warning which I have posted above this seems to be the showstopper in the development. We are developing this for a prestigious client and would request an assistance as soon as possible. P.S :- We are using Xcode 15 with Simulator of version 17.0.

We have an iOS app built using Capacitor. We are seeing a large increase in app crashes on iOS 17.4 (iPhone). Other OS versions seem to be showing significantly fewer crash numbers. We are unsure what is causing this, as our app did not go through any major releases. I have attached the crash log below. Thanks Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: RUNNINGBOARD 0xd00d2bad

How long does it take to change the entity type of the account from Individual to Organization? I changed my account entity from individual to organization two weeks ago, but it still hasn't changed. How long does it take?

We are requesting some information on what should be done in the following case: We have an application that has a privacy manifest, where tracking domains are listed. When the user does not give his/her consent to be tracked, non tracking domains are being used for requests to bring ads. The application in question has a webview where content (ads) are loaded. When a user clicks on an ad, another webview is opened, and this webview does not know that it is in a non tracking flow. Therefore, tracking domains are being used instead of non tracking domains. Since multiple redirections might be in play, there is no way to pass data from the original webview to the one that is opened once the ad is clicked. Would the tracking domains being used in the second webview be blocked? If so, what can we do to circumvent this scenario? Is this even a use case considering privacy manifest? Thanks

I am trying to bring my iOS App to native macOS. I am using exactly the same TimelineProvider and widgets (the ones not supported on macOS surrounded by #if(os)). Running the whole app or just the WidgetExtension on iOS works perfectly fine. Running the mac app works perfectly fine apart from missing Widgets. When running the WidgetExtension on My Mac, the WidgetKit Simulator opens and only presents Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 4.) The code compiles fine without any warnings, only a file path is printed into the console. file:///Users/myName/Library/Developer/Xcode/DerivedData/MyAppName-dfsiuexplidieybwvbkqofchxirp/Build/Products/Debug/MyApp.app/Contents/PlugIns/MyAppNameWidgetExtensionExtension.appex/ Shortly after I get a log entry Logging Error: Failed to initialize logging system. Log messages may be missing. If this issue persists, try setting IDEPreferLogStreaming=YES in the active scheme actions environment variables. I am not sure which further Informationen I can give to solve my problem. Destinations on main App and Widget Extension is both set to Mac (no suffix). The mac is running 14.4.1 and Xcode 15.3. I am really thankful for any assistance you can give me to fix this problem. Thanks
