I am trying to communicate with the backend of my project. So I need to install the certificate into the simulator. I have the .pem file but when I drag-dropped it into the simulator, I got the error "Simulator device failed to complete the requested operation.". The simulator is an iPhone 16 Pro running iOS 18.5. Is there any way to install the cert to my simulator? PS: I can't use Apple Configurator or MDM because I am using the office's Mac. And I can't install anything there. So I can only do it manually.

Hi, anyone managed to make this work? https://developer.apple.com/documentation/backgroundassets Trying for past few days and can't make it work. Following their official documentation, also this video https://www.youtube.com/watch?v=M3jpgZrB1uo, but it seems I am stuck at: try await AssetPackManager.shared.ensureLocalAvailability(of: assetPack) What I did: Manifest files created, info.plist configured, asset pack created and uploaded to appstoreconnect via transporter, successfully assigned to app and ready for internal testing. Added to my code: let assetPack = try await AssetPackManager.shared.assetPack(withID: "Tutorial") try await AssetPackManager.shared.ensureLocalAvailability(of: assetPack) let videoData = try AssetPackManager.shared.contents(at: "Videos/Introduction.m4v") but no luck at all.... is anywhere any demo project available to download to compare with my project?

If I build an x64 binary on my M4 Mini, when I try to debug it using Visual Studio remote debugging the connection is closed, which means I cannot debug my code in x64 mode. I need to be able to do this as I have architecture specific code. I have Rosetta installed. FWIW I have the same issue with lldb-mi :( David

Hello, There seems to be a regression with macOS SDK 15 and dynamically loading libraries if Address Sanitizer is turned on. Seems to only affect Debug builds, and .frameworks. I've also reported this via the Feedback Assistant: FB16513866 Here's a minimal repro, if anyone is interested: https://gist.github.com/peter-esik/6b00432e411be85333e14ae7d953966e I thought I'd post this here, as according to my web searches, this isn't a very well-known bug at this point.

I'm on Mac Studio with Apple M1 Max and I recently upgrated to Sequoia 15.4. After that, Docker won't run anymore. I tried almost all proposed solutions on the web to make Docker to work with Sequoia 15.4 (e.g. workaround at GitHub), without success. Because of this, now I'm stuck in all of my development activities. For example, I cannot develop and deploy anymore my projects and applications. What can I make to solve that?

Based on the stack trace, the issue was likely detected while layout was in progress. Our analytics show this happens generally on app launch and occasionally during normal use. Unfortunately, I couldn't gather additional diagnostic data. I tried to reproduce the issue using the Leaks tool and enabled runtime diagnostics (Address Sanitizer, Malloc Scribble, Zombies), but without success. I may be overlooking something — any suggestions would be greatly appreciated. Thank you in advance

My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

When you have a mac, creating xcprivacy is pretty straightforward for your app, you simply use xcode, then select the sdks and target them and your privacy manifest is ready. In the other hand, when you are using CI/CD solutions you might not use xcode direclty. In that instance and if you are coding in flutter, you need to create your privacy manifest by hand. I would like guidance how to write that file, I would it for a given third party SDK and where to put that file in the flutter project (just to be sure) For example we choose the most important third party SDK manifest: FUTTER framework. I keep getting errors about it for my app, got alot of builds get the INVALID BINARY error because of that, and my mails indicating me a problem with the manifest. Please show me the source code of the manifest privacy for a project where a third party SDK is present (in particular: flutter sdk) Thanks

We are looking for a platform or portal provided by Apple that allows us to track crashes, hangs, or other runtime issues faced by users while using our iOS/macOS application. This is similar to how we currently use Windows Error Reporting (WER) for our Windows application. Important note: Our application is not distributed via the Apple App Store — it is delivered through enterprise distribution or ad-hoc provisioning.

Hello.

On my app I have the necessity to use mergeable libraries, in my context my libraries are indirect dependency, in other words the dependency isn’t target in my project, and they are XCFramework where they are imported on Framework, Libraries, and Embedded Content session on my app target. Following the documentation on Configuring your project to use mergeable libraries it said. 
  But on Manually configure merging don’t said how to configure to indirect dependencies. 
  So I have tried configure use the linker flag -merge_framework for each XCFramework using -Wl, -merge_framework, {XCFramework_Name}, but I am receiving the following error unknown argument: -merge_framework’ when build the release. 

In app target is set build settings MERGED_BINARY_TYPE = manual; The question is: 
 Is possible using mergeable libraries in XCFramework dependencies ? How I do this? Because on the doc is not clear how to use in indirect dependency like XCFramework.

Michel Carvalho

We are experiencing an issue where our app gets stuck during launch. The splash screen appears for some time, and then the app either becomes unresponsive or closes unexpectedly. However, there are no crash logs captured in Xcode or Firebase Crashlytics, indicating that the app is not crashing but rather being terminated. This issue is preventing affected users from properly launching the app. Additionally, some users have reported occasional lag and slow performance when using the app. The issue occurs only for a specific subset of users and appears to be related to other Electronic Logging Device (ELD) apps running in the background. When these apps are active, our app struggles to launch and sometimes becomes unresponsive. We suspect that this behavior could be related to system resource allocation, such as high memory consumption by background apps, which might be affecting our app's ability to launch correctly. However, we have been unable to reproduce the issue on our end despite multiple attempts. Actions Performed During App Launch: Firebase configuration API requests, including: Fetching account details Registering the FCM token with the server Asynchronous background requests to fetch POI details Creating a local database and storing POI data in local storage We would like guidance from Apple regarding potential causes and debugging strategies, especially in scenarios where the app does not produce crash logs but still fails to launch properly. Any insights into memory management, conflicts with background applications, or system resource constraints would be highly appreciated. Steps to Reproduce: Install and launch the app on an affected device. Observe that the app gets stuck on the launch screen. After some time, the app terminates unexpectedly. Issue is inconsistent and occurs only for certain users. Presence of other ELD apps running in the background appears to influence the issue.

I am trying to fix a bug in my iOS app that is dependent upon date and time. Is there any way to set the actual time on the iOS Simulator to a specific date and time? I know that you can set one for the status bar, but that doesn't affect the actual date and time that is reported by the system to apps.

Hello, I'm not a developer. I have an app in the App Store and an Apple Developer account. I have two questions: 1. I'm trying to find out exactly where the source code of my app is located - I can't. It should be in Xcode. There is only Xcode cloud in my account, which is inactive. 2. I want to find out what programming language my app is written in. How do I do this?

I developed (with AI help) using Xcode an app for myself. It logged certain places visited on a list, with photos and notes. It worked, but after a few days my iPhone can't launch it. What do I have to do to get this to last? I didn't think I needed to pay as this is purely for me.

Hi, my server in Melbourne Australia is getting weather forecasts from a few places around Australia. When I look at the daily timesteps that I get back, they might be something like this: "days": [ { "forecastStart": "2025-06-25T00:00:00Z", "forecastEnd": "2025-06-26T00:00:00Z", "daytimeForecast": { "forecastStart": "2025-06-25T07:00:00Z", "forecastEnd": "2025-06-25T19:00:00Z", "overnightForecast": { "forecastStart": "2025-06-25T19:00:00Z", "forecastEnd": "2025-06-26T07:00:00Z",} It doesn't matter where I ask for - Melbourne, Darwin, Perth, it always comes back the same. The documentation says that daytimeForecast is 7 am to 7 pm local and overnightForecast is 7pm to 7 am local. However, in a place like Perth 7-19Z is 3 pm to 3 am, not 7 pm to 7 am like advertised. I can see that for any given date, there are 3 maximum temperature forecasts, a 24 hour max, a daytime max and an overnight max and they differ from each other. Can anyone help me understand what's happening here? And furthermore in the example above, the 24 hour forecasts that have, for example this: "forecastStart": "2025-06-25T00:00:00Z" ... Can the 00:00:00Z be trusted literally? Or is it more the case that it's "2025-06-25" but the HMS got tacked on in a conversion?

Hi Guys, I want to support my client for enable the developer mode, But they not accept to connect with any other devices(Mac Xcode) to enable developer mode. They are nearly 10 people to enable developer mode. But I think without mac we can't enable developer mode in some of devices. So I need a clarification with IOS versions. That's only we are excepting to list out which IOS versions don't have developer mode option default. Please list out that IOS versions Like below: default developer mode available IOS 17.4.1 default developer mode not available IOS 17.5.1
