We are implementing a feature that uses PKPassLibrary.requestAutomaticPassPresentationSuppression to prevent the Wallet from appearing when unlocking a lock. We have already completed the approval process for the entitlement to enable Pass Presentation Suppression. In most cases, our code snippet works as expected, and the result is .success. However, we are also encountering other results, such as .denied, .alreadyPresenting, and .cancelled or .notSupported, which cause the Wallet to appear for users. Here's the code snippet we're using: PKPassLibrary.requestAutomaticPassPresentationSuppression { result in logger.log( .info, "PKPassLibrary suppression result: \(result.description)", LogContext.homeFeature ) } I would appreciate clarification on the following points: What's the meaning of each result type (.denied, .alreadyPresenting, .cancelled, .notSupported) beyond what is mentioned in the documentation? The documentation here does not provide additional details. What is the recommended handling for these specific result states? Should we be taking different actions or retries based on each case? Thank you very much for your help. Best, Ramiro.

We are currently building an app in Swift, reusing an internal C++ backend used in other platforms ( Linux/Windows/Mac ). Current state of the project: App W - ( Swift App ) Package X - Swift Package Y.xcframework - Binary Target (ios-arm64 and ios-arm64-simulator) Z.framework Z - (C++ Backend as a library) Dynamic Library Headers - Library header files Frameworks (Folder) - Required .dylib’s for Z ( libA.dylib (Dependency of Z) [ 58 of them ] libB.dylib (Runtime dependency of python) [ 123 of them ] data - Supporting binary files for Z conf - Supporting configuration files, both text and binary. for Z python - Supporting .py scripts C.py D.py Z.framework ( C++ ) contains 182 Dynamic Libraries. Goal: Validate the app for distribution with the Apple Store validation tool. Learning when trying to solve the problem: A framework can contain only one dynamic library (e.g. .dylib ) A framework cannot have nested frameworks within a Frameworks folder Certain file types within a framework are not treated as resource files (e.g. .py files) Possible solutions Allow to have nested Frameworks in Z.framework. It’s currently not allowed Link 182 dynamic libraries into the project via SPM Problem: Some of the libraries need to dynamically loaded at runtime (related to the python runtime) Making the libraries static adds significantly technical challenges to the Z.framework. Other questions: What’s the best way to achieve this

Hello! I'd like to ask about the best way of getting a list of DNS servers from the system (iOS & macOS). Why? I am using NEPacketTunnelProvider to implement a VPN app. When a device joins a network with a Captive Portal and the VPN is on, the VPN should redirect DNS queries to the DNS servers that were received from the network's DHCP server. So that my VPN is able to correctly reroute the traffic which is not blocked by the network's gateway and the Captive Portal landing page is served. When I don't do anything, the traffic goes to the tunnel and the tunnel's encrypted traffic is then dropped by the gateway serving the Captive Portal. When I temporarily turn off the VPN, opt out of all the traffic or pass the traffic to the system resolver, the traffic gets affected by other network settings (like DNSSettings) which leads to the same situation - the user not being able to authenticate with the Captive Portal. So far, I have tried multiple ways, including res_9_getservers but unsuccessfully. As a part of my investigation, I have found out that the /etc/resolv.conf file is not populated with DNS servers until the Captive Portal is acknowledged by the user which makes getaddrinfo unusable to achieve my goal. But I am not sure if that's a bug or intended behavior. Thank you for your help!

If I have an XCode project that generates a framework when built, then I've noticed that its possible to add new additional targets to the project of type app extension. However if I add some source code to an app extension and regenerate the framework, then that source code is not accessable from the resulting framework (i.e. if the framework is included into an app, then the app code doesn't have visibility of the code that was added to the extension in the framework). Is this something which is possible to achieve? Ideally I would like to package the main source code that constitutes the framework content, along with the source code for a few extensions into a single framework, so that the app(s) that use the framework can include the framework into their main app target and also include it in the app extension target. I noticed that if the scheme of the framework is changed to the extension before building, then the result is not a .framework file but a .appex file. For client apps of the framework, can they directly include/use that .appex file? If so how can that be achieved? Does

I have a problem with rulers in an NSTextView. My code has worked fine from about Sierra (10.12), up to Ventura (13), it stopped working in Sonoma and continues to fail in the same way in Sequoia (14 - 15). When I display the ruler, the contents of the text area disappears leaving just a pale grey background. When I make the ruler invisible again the text reappears. No errors are reported (at compile or run time). I have tried adding refreshes of the text view in various places with no result. I have (for Sequoia) used Interface Builder to force the text view to use TextKit 1, also with no success. I’m at a loss as to how to proceed because I’m not getting any diagnostics, simply changed behaviour. My app provides a programming IDE. It includes a program editor that uses line numbering code for an NSTextView from WWDC/Noodlesoft. The line numbers are shown in the ruler which is sometimes visible and sometimes not. When I display the ruler, I also set the main text to not editable but removing this setting does not appear to make any difference.

I'm still discovering swift and the various frameworks. So I'm now trying to create scrolling composition with a grid - containing images - and an NSStackView at on top. However, I'm running into a problem that might seem stupid, but when I try to wrap my NSCollectionView in another NSView and pointing the scrollView.documentView to, I can't scroll anymore...

Hello Apple Developer Community, I am currently working on a macOS project where my primary goal is to intercept IP packets, modify them (specifically the TCP payload), and then forward them. My intended use case involves selectively intercepting outgoing packets based on their destination IP, altering their content, and sending them on their way to the original destination. What I’ve Tried: NEAppProxyProvider: • I explored using App Proxy Provider to handle new TCP and UDP flows. • While it allowed me to read the data, handling direct packet modification and forwarding without creating a new connection or proxy setup proved challenging, especially for maintaining TCP state and handling TLS traffic. System Extension with NEFilterPacketProvider: • I considered NEFilterPacketProvider for intercepting and modifying network packets. • However, the documentation implies that packet filtering only supports allow/block actions, not modification and reinjection of packets back into the system. I am planning to try NEPacketTunnelProvider: But the documentation states that this is not the right use case. Packets are expected to go into the tunnel. Since I don't have any requirement to create and maintain a tunnel, this doesn't look like an option for me. Transparent proxy setups like NETransparentProxyProvider do not appear to offer direct packet modification capabilities without involving a user-space proxy approach. Implementing packet-level interception outside of the Network Extension framework (e.g., Network Kernel Extension) seems unsupported in newer macOS versions (Sequoia and later). My Questions: Is there a recommended approach or combination of Network Extension capabilities that would allow intercepting and modifying IP packets directly? Can NEFilterPacketProvider or any other extension be utilized in a way to modify and reinject packets back into the system? Are there any examples or sample projects that achieve similar functionality, possibly using a blend of Network Extension and lower-level networking frameworks? I appreciate any insights or pointers to documentation or examples that could help achieve this. Thanks and Regards. Prasanna.

Hi Folks, do you know what happend with the "shape detection API" feature flag on Safari 18.X (IOs 18.X)?... in previous versions (17.X) i enabled the "shape detection API" feature flag and was able to detect codes like mentioned here... https://developer.mozilla.org/en-US/docs/Web/API/Barcode_Detection_API#browser_compatibility I built a PWA (Service Worker) with Angular 18 and facing this issue immediately after updating to IOS 18.0 (I enabled/disabled the flag, restartet the device several times... no success at all) Do you have an Idea what changed or how i can enable that feature again? Thx a lot in advance.. Cheers Martin

Hello everyone, I’m experiencing an issue with the Android Emulator in Android Studio (version Ladybug) on my Mac running macOS Monterey (12.7). The emulator frequently displays the message “System UI isn’t responding” and then crashes. I've tried a few troubleshooting steps, including: Restarting Android Studio and the emulator. wipe data on AVD. tried to change the emulator performance from automatic to hardware but this option isn't available to me. Despite these efforts, the problem persists. Has anyone else encountered this issue? Any suggestions or solutions would be greatly appreciated!

Hello, I`m working on an app that uses CloudKit and CKShare, but the app has 2 different targets, one for professional and one for patients, and theoretically the target of the professional sends the CKShare and the target of the patient should accept, but the ckshare tries to always open the target of the profissional, I would like to know if the are any way to configure the CKShare to oppen the target od the patients

Hi! My simulator will not build because there is essentially a package conflict. I am adding Firebase to a Flutter application. Simulator built before trying to add firebase but now I'm getting errors telling me a package can't be found even though it's installed Output Package Loading (Xcode): Missing package product 'FirebaseCore' .../ios/Runner.xcodeproj I added target 'Runner' do use_frameworks! use_modular_headers! pod 'FirebaseDatabase' pod 'FirebaseAnalytics' pod 'FirebaseMessaging' pod 'FirebaseCore' pod 'FirebaseFunctions' pod 'FirebaseAppCheck' pod 'FirebaseFirestore' pod 'FirebaseStorage' pod 'FirebaseDynamicLinks' pod 'FirebaseAuth' flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__)) target 'RunnerTests' do inherit! :search_paths end end and ran pod install with no errors. Opening the runnner.xcworkspace shows all of the named packages under "Frameworks, Libraries, and Embedded Content' I've tried manually adding through Xcode those packages but then get a conflict error, so I am out of ideas as to how to fix this. It appears to be something new with the latest MacOS update as I've seen another person with the same problem that started after he updated... I've also cleaned, re-installed, re-booted a few times because My Android emulator builds fine Any help would be appreciated! Thanks!

I want to release a Framework F, containing several other frameworks (such as Realm, Appetitive, Cocoalumberjack, PhoneNumberKit) for use by app A. According to this article: https://medium.com/@bittudavis/how-to-create-an-umbrella-framework-in-swift-ca964d0a2345 They write, without referencing a source: "Although Apple discourage creating umbrella framework". Is that true, do Apple discourage umbrella frameworks, if so why and is it a very strong discourage or a mild one? If not discouraged, then how can this be achieved with Xcode 16? I've been attempting to follow a few tutorial to achieve this, such as https://medium.com/john-lewis-software-engineering/adding-a-third-party-framework-inside-a-first-party-framework-in-xcode-3ba58cfd08da however so far without any success. This last article mentions the Link Binary With Libraries section, which doesn't exist in Xcode 16. There's the Frameworks, Libraries, and Embedded Content section where I have been attempting to add the frameworks into my Framework F (choosing Embed without Signing). I'm able to successfully build Framework F, but when app A attempts to use it (adding F to the Frameworks, Libraries, and Embedded Content section with option embed and sign, or embed and don't sign, makes no difference) then I get run time errors about the umbrellaed frameworks not being able to be found.

In iOS 17, the call to "UIApplication.shared.open("App-prefs:ACCESSIBILITY&path=HEARING_AID_TITLE")" was opening the device Settings and going to Accessibility and then Hearing Device which is very helpful. Now in iOS 18, this call only opens the device Settings at the root. I would like to know how to replace the URL so that it works like before. canOpenUrl does return true, so I'm wondering if something is broken, or if canOpenUrl is kind of lying a bit. I also tried other paths to go to other screens and they don't work either.

When converting some of our frameworks to universal frameworks (multiple target platforms), error messages appear in Xcode that we believe are incorrect: Something like this: Umbrella header for module ‘TestFramework’ does not include header ‘iOS.h’ This post links to an example project which shows the behaviour (UmbrellaHeadersTest.zip). See the included README.txt Any suggestions on how to reliably eliminate these warnings would be greatly appreciated! UmbrellaHeadersTest.zip

For a UIKit app based on scenes (UIScene), is it safe to reference UserDefaults in code that is executed from UIApplicationDelegate/application(_: didFinishLaunchingWithOptions:) ? I've read that in iOS 15, there were undocumented scenarios involving app prewarming that would cause UserDefaults reads to fail within a window of time after device reboots, as described at https://christianselig.com/2024/10/beware-userdefaults/ The failure mode is that an app would be released, and months later, a small fraction of users would report failures consistent with UserDefaults reads unexpectedly returning nil, causing a loss of data. The user experience is bad, and debugging this behavior is then challenging because of how rarely it occurs. Apple's https://developer.apple.com/documentation/uikit/app_and_environment/responding_to_the_launch_of_your_app/about_the_app_launch_sequence#3894431 seems to suggest that prewarming only executes an app "up until, but not including when main() calls UIApplicationMain(_:_:_:_:), but https://stackoverflow.com/questions/71025205/ios-15-prewarming-causing-appwilllaunch-method-when-prewarm-is-done documents that UIApplicationDelegate/application(_: didFinishLaunchingWithOptions:) has in fact been observed executing during app prewarming in scene-based apps. So, my question: In an app based on scenes, if I'd like to reference UserDefaults within UIApplicationDelegate/application(_: didFinishLaunchingWithOptions:), when is it safe to do this? I'm guessing the answer is one of these: Never. Only in apps that don't support scenes. Only in iOS 16 or later. Only in IOS 17 or later. Is it guaranteed safe to reference UserDefaults in UIWindowSceneDelegate/scene(_:willConnectTo:options:) or later? Is there documentation from Apple regarding this issue? Thank you.

Does Cocoa have documentation that describes why this functionality is not supported? To try it out is simple, create a default application that uses Objective C in XCode, add a button that toggles the window into fullscreen and opens a modal save-as dialog at the same time. The fullscreen transition will half-complete but kick the application out of fullscreen instantly. Is this expected behavior? The test application is attached below. The XCode test application
