My company has been developing a DriverKit Extension for our ThunderBolt attached devices. Our testing has gone well on Intel based machines but it seems to be able to cause kernel panics on my M1/M2 Mac when click "Allow" in Privacy & Security. It always crash immediately. Unfortunately it is " ApplePPMCPMS: Could not register client id 5. Error code 0xe00002bc " and I have no way to debug it. Has anyone deal with something like this? panic(cpu 5 caller 0xfffffe002fd92b7c): "ApplePPM: virtual IOReturn ApplePPMCPMS::callPlatformFunction(const OSSymbol *, bool, void *, void *, void *, void *):2003 " "ApplePPMCPMS: Could not register client id 5.

I have a host application and I've added an extension to it. The bundle IDs of the two are different. Do I need to apply for a separate Provisioning Profile for the extension?

Hello, While developing an extension for Safari using Manifest V3, I encountered an issue where my service worker stops functioning; it simply disappears, and I'm unable to revive it in any way. I've attempted to send messages from popup.js and content.js, and even tried setting an alarm with a 20-second interval. However, the worker remains unresponsive until the browser or the extension is reloaded. The logic of my extension operates through background.js (worker). What steps should I take to restore the functionality of the worker? Thank you for your assistance.

I have a NotificationContentExtension, to create a custom view for a notification. This view contains several links (crucially, these are not defined as . The desired behavior is to open the url in a webview in my main app. However, using self.extensionContext.open opens the url in safari. Given that UIApplication.shared is not available in an extension, how should I go about opening a url in my main app from a notification?

We use a local swift package in 6 of our app extensions. The product from the local package that we link to each app extension is a dynamic framework. And while the dynamic framework is copied into the final app bundle once, the resource bundles of each target that comprise the dynamic framework is copied into each app extension. I'd much rather have the bundles be copied into the dynamic framework once to prevent app bloat. Here is a visualization of the issue: . └── MyApp.ipa/ ├── MyApp (executable) ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle ├── MyDynamicFramework_TargetC.bundle ├── Frameworks/ │ └── MyDynamicFramework.framework/ │ ├── TargetA │ ├── TargetB │ └── TargetC └── PlugIns/ ├── Widgets.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── Intents.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── IntentsUI.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── NotificationContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle ├── RichPushContent.appex/ │ ├── MyDynamicFramework_TargetA.bundle │ ├── MyDynamicFramework_TargetB.bundle │ └── MyDynamicFramework_TargetC.bundle └── NotificationService.appex/ ├── MyDynamicFramework_TargetA.bundle ├── MyDynamicFramework_TargetB.bundle └── MyDynamicFramework_TargetC.bundle Notice that the resource bundles of Target A, B, and C are copied multiple times causing an unhealthy app size. I'd either like the resource bundles to be copied into MyDynamicFramework or copied once into the app bundle and let the app extensions reference them. Given the SPM + Xcode linking is a black box for the most part, how would I accomplish this?

I have some visualisation-heavy AUv3's, and the goal is not to perform graphics-intensive tasks if the plugin window is not opened inside the host app (such as Logic Pro). On iOS, this is easily accomplished by the viewWillAppear, etc overrides. But on macOS, it seems these overrides are not called every time the user opens / closes the plugin windows in the host application. I did try some alternate methods, like trying to traverse the view / controller hierarchy, or make use of the window property, to no avail. What substitute mechanism could I use to determine visibility status of an AUv3 on macOS? Thanks in advance, Zoltan

Hi, I run the converter my chrome exrension to a safari extension. I'm trying to pass the device data like the MacAddress of the device and IP address of my device to background.js in my chrome extension. How do I do that? I've tried several ways but I can't get it to work. Please help me,

Every time I try to update my newest sticker pack in Xcode, It gives me this error "warning: The CFBundleShortVersionString of an app extension ('1.2') must match that of its containing parent app ('1.0')."

Our app has a share extension. And we recently noticed something with iOS 17.3.1. From Safari, when we receive the plist and try to load it, we are seeing exceptions for classes not allowed to be unarchived. [itemProvider loadItemForTypeIdentifier:[UTTypePropertyList identifier] options:nil completionHandler:^(NSDictionary *jsDict, NSError *error) { } We see these exceptions: value for key 'NS.keys' was of unexpected class 'NSString' (0x1ee7d2970) [/System/Library/Frameworks/Foundation.framework]. Allowed classes are: {( "'NSDictionary' (0x1ee7cad38) [/System/Library/Frameworks/CoreFoundation.framework]" )} (null) Our preprocessing javascript file is basic, and only passes a title and URL as part of the payload. arguments.completionFunction({ "URL": document.URL "title": document.title, });

Several of our users are having an issue where they cannot make or receive Teams calls from their iPhones. I believe this is an issue that began with IOS 17.2 and which Apple has acknowledged and committed to fixing. may I know what is the status of this fix? or if there is a solution?

Any extension views called from ASCredentialProviderViewController -> open func prepareInterface(forPasskeyRegistration registrationRequest: ASCredentialRequest) cannot be accessed through Keyboard (Setting->Accessibility->Keyboards->Full Keyboard Access enabled). I have to manually type the prompted screen once to be able to get focused and continue to use Keyboard. Is it a known issue or I am missing anything? Please suggest. Thanks!

I am trying to add an extension, that adds two functions to an array of FloatingPoint types. I added to and extension to get a myDesibe var: extension FloatingPoint { public var myDescribe:String { return String(format:"%.3f",self as! CVarArg) } } This works fine (or seems to) On the collection, I want to add two methods/vars. One method returns a string with command delimited values: public extension Array where Element: FloatingPoint { var myDescribe:String { var rvalue = "" for (index,entry) in self.enumerated() { var format = ",%@" if (index == 0) { format = "%@" } rvalue += String(format: format, entry.myDescribe) } return rvalue } } That seems to be working fine. The other I wan to pass the command delimited string in, and get an array of the type of elements of the Array. This does not work: public extension Array where Element: FloatingPoint { var myDescribe:String { func fromDescription(desribe:String) -> [Element] { var rvalue = [Element]() for entry in desribe.components(separatedBy: ",") { let trimmed = entry.trimmingCharacters(in: .whitespaces) let temp = FloatLiteralType(trimmed) ?? FloatLiteralType.zero // Now, how to convert this so I can append this in the array? This is the issue!! rvalue.append(temp) // << THIS FAILS, as it wants an Int which I don't `understand` } return rvalue } } All help is appreciated Charles

I have an iOS app with widgetkit extension, and the widgets stopped updating. I attached the console, and saw these lines for widgets of my app: com.apple.widget.myApp::myWidgetKind::-6207022974507159915:417E34:[ {name: Widget Refresh Policy, policyWeight: 0.010, response: {Decision: Must Not Proceed, Score: 0.00, Rationale: [{onOverrideList == 1 AND IndividualBalance == -1}]}} ], FinalDecision: Must Not Proceed} The IndividualBalance == -1 apparently means that the app was updating widgets too often, but what about onOverrideList == 1? There seems to be no info online about this flag, and LLMs seem to suggest that the app got onto some kind of Apple's blacklist for updating too often, is that right?

I have a text based action for iPhone and Mac Catalyst I am developing in Xcode 14.3.1 on macOS 13.4.1. I have the container app, an action and an AppGroup defined. I have confirmed that I can read the necessary shared defaults when the action launches. At this point the UI for the action is a simple textview in which I hope to display a modified version of the text passed to the action in the NSExtensionItems. I am not using a simulator. I am running the action directly using Xcode. What is happening is that the ActionViewController viewDidLoad runs but no visible window opens. In the console I see this as the action launches: 2023-07-05 18:27:23.692277-0700 XYZ[4634:279295] [ViewBridge] ViewBridge attempted to look up a hosted window with identifier 8E816BD5-67D3-402D-ADEB-AC59EDFA1F3B, but it was never registered. 2023-07-05 18:27:23.692408-0700 XYZ[4634:279295] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set. .... The last line above is repeated 12 times.... Any helpful ideas would be deeply appreciated! Steve

I wanted to implement a feature that allows the sharing of multiple files simultaneously to my app from an external app like Files. In my ApplicationDelegate file, I provided the following method, which currently only retrieves a single file URL from the share sheet, even when multiple files were selected in the Files app: - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options { return [self handleSharedURL:url options:options]; } I'm curious to know if there is a way to obtain multiple file URLs without relying on a share extension. Any advice would be greatly appreciated.

I am trying to run a simple bash script from within swift. Eventually it should call a python script, but for now, I am just trying to get it to echo hello. The script is included in the bundle and also included in the targets. The script is called from the QLExtension. The script is correctly found, but I get an error: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted" let scriptPath = Bundle.main.path(forResource: "run_local", ofType: "sh") if scriptPath == nil { print("script not found or other error") return nil } let process = Process() process.executableURL = URL(fileURLWithPath: "/bin/bash") process.arguments = [scriptPath!] do { try process.run() process.waitUntilExit() } catch { print("Failed to run the script: \(error)") } The script, run_local.sh is included in the bundle and is just #!/bin/bash echo "hi" > /dev/null Is this possible? Are there any particular entitlements that I need in order for this to work? Everything else works with this app; this is the only error. -- The reason I am building this: I use google drive to synchronize files locally. A number of those files do not have a local representation. Google "stores" those files locally using a text file with a document ID (one would open something like docs.google.com/docs/) I want to be able to preview the google drive files using quicklook One very simple way to do this is to fetch the google drive files (using google drive API) at preview time. I have a python script that can do this and wanted to hook it up to the QLExtension for preview Another option is to keep a separate service running (I would use python) that keeps a local copy of all the synchronized google files. (But then I'll probably need to connect to a local sql database or similar that tells the swift extension the local file math: i.e., effectively a mapping from ID => local_file_path. But perhaps access of this kind to a SQL database is allowed?)
