I'm working on an API client for a REST service that uses a custom token-based authentiation scheme. The app hits a specificed authentication endpoint with a username and password, said endpoint returns a token that's good for X amount of time, and the app passes that token along with every subsequent request. When that token expires, we start over.Most literature out there tells me to manually set the Authorization header on my request, but official Apple documentation discourages this, as that header is meant to be 'owned' by the built-in HTTP loading system. That said, official documentation on the 'correct' way to do this is shockingly lacking, and the standard didReceiveChallenge callbacks seem better suited for non-custom Basic/Digest/etc authentication schemes. One thought I had was registering my own URLProtocol subclass to handle our custom flow. However, while I haven't had a chance to sit down and take a crack at that yet, my understanding from skimming these forums is that it's suffering from some bit-rot right now, so it 'might' (?) not be the best choice. That, and it's also not clear to me whether the rules around the Authorization header change when a custom URLProtocol is in play.So, community (paging eskimo in particular!), what's the correct way for me to go about this?

On iOS:When one receives a file of type .pages by email, Mail displays a large Pages icon and tapping on it opens Pages. (A long-press brings up the more complicated Actions screen).When one receives a file of type .vcf by email, Mail displays a large Contacts icon and tapping on it opens Contacts. (A long-press brings up the more complicated Actions screen).I have my own custom file type, .ripf, and I want to have the same behaviour because that is what my users will expect. Accordingly, in my app's Info.plist I have a CFBundleDocumentTypes dictionary providing a one-element LSItemContentTypes array referring to the name 'com.universalis.ripcard', and a UTExportedTypeDeclarations dictionary associating the UTTypeIdentifier 'com.universalis.ripcard' with a public.filename-extension 'ripf' and a public.mime-type 'text/vnd.universalis.ripcard'. All the other entries in those two dictionaries are present and correct as far as I can tell. Both CFBundleDocumentTypes[0].CFBundleTypeIconFiles and UTExportedTypeDeclarations[0].UTTypeIconFiles contain a list of icon files for the file type.(That rather long paragraph is to avoid boring people by including the entire Info.plist!)Some things do work..ripf files received via AirDrop bring up a suitable "Open with..." message which mentions my app, and tapping the message opens the app..ripf files received as an email attachment display as an icon. But it is the app's icon and not the icon of the file type.BUTTapping on a received file's icon does not open the app, but only opens the generic Actions screen, offering Message, Mail, WhatsApp, Notes, and only then (after the user has scrolled sideways) "Copy to..." my app.Now, the whole apparatus of CFBundleDocumentTypes and UTExportedTypeDeclarations is obscure and under-documented, and indeed the main documenation for the latter has a big warning at the top saying that it is obsolete and not being updated. That doesn't matter so much. What I need to know is:(Less important): How do I get the right file icon?(More important): How do I get my app to open when the icon is tapped, as Pages and Contacts do? There must be a way – unless special cases for those two apps are wired into iOS itself.

Has anyone had success attempting to place a PKCanvasView in front of an image / UIImageView ?Setting the canvas backgroundColor to clear appears to work correctly, however when finger/pencil touches down the background of the PKCanvasView reverts to black 100% alpha.ThanksBen

When selecting a stroke path for object on PKCanvas, the option "Snap to Shape" appears. I understand this function is still in beta and has not made available natively to other PencilKit app. Is there a way using Stroke API to call this function directly after the user hold pencil for half a second when stroke is done drawing, just like how it behaves in native apps?

i thought it is impossible to have CallKit show system UI for outgoing calls. but then i saw this: "For incoming and outgoing calls, CallKit displays the same interfaces as the Phone app..." https://developer.apple.com/documentation/callkit how do i present it though? or is this a documentation error?

I have an app developed by using the Callkit/Call-Blocking and received feedback from individual users, when using [cxcalldirectorymanager reloadextensionwithidentifier] to write call blocking data, it returned error code 11 with the following contents: errorCode: 11 errorDomain: com.apple.callkit.database.sqlite errorDescription: sqlite3_step for query 'DELETE FROM PhoneNumberBlockingEntry WHERE extension_id =?' returned 11 (11) errorMessage 'database disk image is malformed' I want to know the reasons for this error and how to solve it，Thanks!

Is there any resource which describes this type of errors? I was integrating SKADNetwork view through Ad attribution and everything from the source app side is done and this error appears after the target app is installed and opened.

If anyone can help, you would be doing me a solid, Thanks in advance.

IMPORTANT Rather than use the code below, I recommend that you adopt Swift’s shiny-new Subprocess package. That’s what I’m doing! (-: Running a child process using Process (or NSTask in Objective-C) is easy, but piping data to and from the child’s stdin and stdout is surprisingly tricky. I regularly see folks confused by this. Moreover, it’s easy to come up with a solution that works most of the time, but suffers from weird problems that only show up in the field [1]. I recently had a couple of DTS incidents from folks struggling with this, so I sat down and worked through the details. Pasted below is the results of that effort, namely, a single function that will start a child process, pass it some data on stdin, read the data from the child’s stdout, and call a completion handler when everything is done. There are some things to note here, some obvious, some not so much: I’ve included Swift and Objective-C versions of the code. Both versions work the same way. The Swift version has all the comments. If you decide to base your code on the Objective-C version, copy the comments from there. I didn’t bother collecting stderr. That’s not necessary in many cases and, if you need it, it’s not hard to extend the code to handle that case. I use Dispatch I/O rather than FileHandle to manage the I/O channels. Dispatch I/O is well suited to this task. In contrast, FileHandle has numerous problems working with pipes. For the details, see Whither FileHandle?. This single function is way longer than I’d normally tolerate. This is partly due to the extensive comments and party due to my desire to maintain focus. When wrapping Process it’s very easy to run afoul of architecture astronaut-ism. Indeed, I have a much more full-featured Process wrapper sitting on my hard disk, but that’s going to stay there in favour of this approach (-: Handling a child process correctly involves some gnarly race conditions. The code has extensive comments explaining how I deal with those. If you have any questions or comments about this, put them in a new thread. Make sure to tag that thread with Foundation and Inter-process communication so that I see it.

I am wanting to not only surface my content in the system-level Spotlight search results but also to utilize the same index for my in-app search screen. The very few examples or tutorials I could find all craft a CSSearchQuery string using just the "title" attribute. I can't figure out where to look to understand how to search across other attributes. My most pressing need is to be able to perform a CSSearchQuery looking for a search term in the .htmlContentData attribute. If I search for this term in the system search field it returns results, so I know it's being indexed. However when I use a search query (in my app) like htmlContentData == "someSearchTerm" I get zero results. This frustration has led to some more general questions like: How do you know what attribute names are available to use in the search query? Is it just a string literal that's exactly the same as the CSSearchableItemAttributeSet property in Swift? e.g. property .htmlContentData is referred to as "htmlContentData" in the query string? Also, is there any way to just search across all attributes with CSSearchQuery? Obviously using the system Spotlight search (from Home Screen) you don't have to specify if you're searching the title or htmlContentData, it just finds it in either. Yet for CSSearchQuery I have to know up-front which fields I want to look in?

I have two call directory extensions, each with InfoPlist.strings in en.lproj and nb.lproj directories. In these files I've defined CFBundleDisplayName for both locales. These names are displayed under Settings -> Phone -> Call Blocking & Identification. On iOS 12.2 the names are displayed correctly in both Norwegian and English. Testing on iOS 15.3 the English names are displayed even when device language is set to Norwegian. Worth noting: When updating the English versions of CFBundleDisplayName this is immediately reflected in Call Blocking & Identification page with Norwegian device language. As this feature requires a real device, I'm unable to test on iOS 13 and 14.

I'm trying to use ScreenCaptureKit on a Mac Catalyst app, on macOS 12.5.1. I'm not sure if I'm doing something wrong, but it crashes as soon as I try to request SCShareableContent. It crashes on internal code, calling a method it can't find, which makes me think this is a bug in the framework rather than incorrect configuration. Any hints on how to work around this problem? The crash is: ** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[RPDaemonProxy fetchShareableContentWithOption:windowID:withCompletionHandler:]: unrecognized selector sent to instance 0x6000037d5dc0' terminating with uncaught exception of type NSException ScreenCaptureKit-Crash.txt

I've been trying to add a CoreSpotlight indexer to my macOS application. The new template for the indexer uses the new appex CSImportExtension style importer. I've been following this -> https://developer.apple.com/documentation/corespotlight/csimportextension I changed the CSSupportedContentTypes in the Info.plist file to the correct file type uti. I added a dummy value into the attributes (see code below) - just setting contentDescription to 'noodle' (easy to search for) class ImportExtension: CSImportExtension {   override func update(_ attributes: CSSearchableItemAttributeSet, forFileAt: URL) throws {     // Add a dummy value, and see whether spotlight finds it     attributes.contentDescription = "noodle" } } I have a number of files on disk that match the uti (and can be found when I search by the file name) Yet, when I build and run my app, the a spotlight search for 'noodle' finds no results. Can anyone give me any advice? I cannot find any indication that the ImportExtension is called (although when I put a log message at the start of the update() call there's no message in the console which seems to suggest it's not being called). Is there any way of debugging this? Cheers and thanks -- Darren.

Hello, The purpose of "Screen Time Passcode" under Settings/Screen Time is to protect Screen Time preferences and it is asked every time the user updates Downtime, App Limits, Content & Privacy Restrictions and so on. But the private passcode is not requested if the user disables Screen Time for a particular app (only Face ID or phone passcode is requested, but not the private Screen Time passcode). I think this is a mistake, I think the purpose of a private Screen Time passcode is to protect all settings, including apps that use this API, right? Is there any solution to this? Thank you.

When I tap on one of the buttons in the ShieldAction extension I want to close the shield and open the parent app instead of the shielded app. Is there any way of doing this using the Screen Time API? class ShieldActionExtension: ShieldActionDelegate {      override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {     // Handle the action as needed.           let store = ManagedSettingsStore()               switch action {     case .primaryButtonPressed:       //TODO - open parent app       completionHandler(.defer)     case .secondaryButtonPressed:       //remove shield       store.shield.applications?.remove(application)       completionHandler(.defer)         @unknown default:       fatalError()     }   }   }

Hello, I want to echo the DeviceActivityReport "concurrency" problems flagged in https://developer.apple.com/forums/thread/720549, and ask a related question. (Thanks to Kmart and other Apple dev support folks who have been monitoring these forums and responding diligently.) I would like to display daily and weekly stats in the same view, broken down by specific apps (as in the native Screen Time). However, instantiating multiple DeviceActivityReport objects with different filters and/or different contexts leads to confusion, where the two views will incorrectly and intermittently swap data or duplicate data where it shouldn't (seemingly upon some interval when the extension provides fresh data). There isn't documentation on how to display multiple reports at once. Is the idea that logic for multiple reports should be embedded within the extension itself in the makeConfiguration() function and there should only be a single DeviceActivityReport in the main App, or is this a bug? Even with a single DeviceActivityReport, I run into inconsistencies where the View provided by the extension takes multiple seconds to load or fails to load altogether. The behavior seems random...I will build the application with the same code multiple times and see different behavior each time. Finally, a plug for better support in the Simulator for the entire set of Screen Time APIs. Thanks!
