I'm sitting at my house and trying to sign my test device out of my apple ID so I can sign into a Sandbox user, but now I have an hour to kill because of this terribly broken "security" feature that thinks it's in an unfamiliar location, despite being at the only location it's ever known. Looks like I'll just be disabling this feature all together. Especially as a device with Developer Mode enabled, which gets reset regularly, there should be additional options here. Come on!

Hey there! I faced issue in iOS 18 and newer when Spotlight search doesn't show my App in results. In older versions it works. Here is my code: func configureUserActivitity(with id: String, keywords: [String]) { let activity = NSUserActivity(activityType: id) activity.contentAttributeSet = self.defaultAttributeSet activity.isEligibleForSearch = true activity.keywords = Set(keywords) activity.becomeCurrent() self.userActivity = activity } I didn't find any reasons why it doesn't work now. Maybe I should report a bug?

I am looking to set environment variables for the use of some applications that are launched by icon or from the dock. I am aware of launchctl setenv for setting environment variables, but I am also aware that the effects of that last only until the next reboot. I find various people posting hacks that come down to configuring some .zsh* initialization files, but those fines are not used until an interactive login session is started, and so are not of value for the case where the user does not happen to launch terminal The particular environment variable of interest at the moment is JAVA_HOME for use by MATLAB . MATLAB is started by the shell script /Applications/MATLAB_R20xxx.app/bin/matlab and does not appear to have a .plist file associated with it . Editing the shell script would not be ideal.

I use WeatherKit with Swift to get multiple cities weather by longitude and latitude. But I use this API in WeatherService for daily forecast: final public func weather<T>(for location: CLLocation, including dataSet: WeatherQuery<T>) async throws -> T And I found there is something wired: The date of WeatherKit::DayWeather is based on my device's timezone settings. Tokyo's Day Weather is start at UTC+8, New York' Day Weather is start UTC+8. Is there any way to set timezone correctly?

Hello! I’m trying to handle custom URLs (e.g., customurl://open?param=value) that open the app. However, while the app launches via the custom URL as expected, the parameters are not being passed to or are accessible from the iOS-specific implementation. Currently, if I open a custom URL via Safari, the app gets launched but the custom URL and parameters are not accessible. customurl://open?hello=test According to the iOS Docs ( https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Handle-incoming-URLs ) any URLs should be passed to: func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:] ) -&gt; Bool I do not register the above application function to be called but instead this one is executed during app start with launchOptions always being nil: func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -&gt; Bool This is the case regardless of if the App is started fresh or was already running in the background. My pInfo entry for the custom URL: &lt;key&gt;CFBundleURLTypes&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;CFBundleTypeRole&lt;/key&gt; &lt;string&gt;Viewer&lt;/string&gt; &lt;key&gt;CFBundleURLName&lt;/key&gt; &lt;string&gt;dev.customurl.project&lt;/string&gt; &lt;key&gt;CFBundleURLSchemes&lt;/key&gt; &lt;array&gt; &lt;string&gt;customurl&lt;/string&gt; &lt;/array&gt; &lt;/dict&gt; &lt;dict/&gt; &lt;/array&gt; TLDR: How can I access the parameters, passed with the URL? Any thoughts on what I am doing wrong?

Hi everyone, I'm working on an app for parents and kids where parents can define screen time goals or restrict usage of certain app categories (like social media or games). If the kid follows those rules—for example, by using their device less or avoiding restricted categories—they would earn points or rewards in the app. I’ve been exploring if the Apple Screen Time API allows developers to access this kind of data (like total screen time, app usage by category, etc.) so that I can track the kid’s behavior and reward them accordingly. Is it possible to programmatically access this data and implement such a reward system within my app? If so, what’s the best way to get started or which APIs should I look into? Thanks in advance for your help!

Hi! We are having a hard time with the universal link, help is appreciated! Thanks in advance! The universal link doesn't work after installation for some time. A user has to wait for from 5 to a couple of hours after the app is installed on the device. This has also affected App reviewers since we need the universal link to work for successful login. Each submission will receive a rejection of we cannot login and it will be approved until we kindly ask them to try again. I believe the JSON is delivered to devices by Apple's CDN system and the fact that it works on most devices most of the time should imply that we have a valid apple-app-site-association setup. So I am really confused about the wait time, which is giving us trouble with app review and a bad user experience

In Core Spotlight, one can only index content by using title or displayName, and it requires four consecutive characters for indexing. These situations occurred in iOS 17 and 18. In iOS 16, I could not only index content by title or displayName, but also by keyword. Moreover, there was no restriction of requiring four consecutive characters. I could index my app content by simply inputting one character. Here is my code.https://github.com/kritto1/corespotlight-bug-test/tree/main @available(iOS 14, *) func addItemToIndex(_ item: QSpotlightItem) { let attributeSet = CSSearchableItemAttributeSet(contentType: .item) attributeSet.title = item.title attributeSet.displayName = item.title attributeSet.contentDescription = item.contentDescription attributeSet.keywords = item.keywords attributeSet.thumbnailData = item.thumbnailImage attributeSet.contactKeywords = item.keywords attributeSet.supportsNavigation = true let searchableItem = CSSearchableItem(uniqueIdentifier: item.id, domainIdentifier: "com.qunar.iphone.spotlight", attributeSet: attributeSet) searchableItem.expirationDate = .distantFuture CSSearchableIndex.default().indexSearchableItems([searchableItem]) { error in if let error = error { } else { } } } @available(iOS 14, *) func addToSpotlightIndex() { let spotlightHotel = QSpotlightItem( id: "corespotlight_1", title: "查询酒店住宿", contentDescription: "", thumbnailImage: UIImage(named: "img2")?.pngData(), keywords: ["酒店", "住宿"] ) addItemToIndex(spotlightHotel) let spotlightFlight = QSpotlightItem( id: "corespotlight_2", title: "查询和预订机票", contentDescription: "", thumbnailImage: UIImage(named: "img2")?.pngData(), keywords: ["查询", "预订", "机票"] ) addItemToIndex(spotlightFlight) let spotlightSight = QSpotlightItem( id: "corespotlight_3", title: "查询预订门票", contentDescription: "", thumbnailImage: UIImage(named: "img2")?.pngData(), keywords: ["查询", "预订", "门票"] ) addItemToIndex(spotlightSight) }

I've been working a lot with the FamilyControls API and App Shield recently but have encountered a problem with no documentation. I used the FamilyActivitySelection to select the app store to shield(This is just for testing), and then printed out the application token: 1wfY¸êB ò S« öi #×(É?âðw ù/jQ ¿ J ïE¢? ·¿ º<Òd?ý r7¥Ãn N átJ¹ÿ85B_{VAF fC8. ,,¸¯3 T7F ±õü; ¹?v@¯ô Ä \-õ# Ò I know the application token is a Codable object so I was wondering, How do I create an application token using the Token<Application> initializer init(from: any Decoder) throws Creates a new instance by decoding from the given decoder. Using the above data? Do I have to encode first in order to decode it? For reference, the code I tried to use is: newValue.applicationTokens.encode(to: JSONEncoder) if let encoded = try? JSONEncoder().encode(newValue.applicationTokens) { data = encoded print(String(data: data, encoding: .utf8)!) } if let app = try? JSONDecoder().decode(Token<Application>.self, from: data) { let token = Application(token: app) print(token) } else { print("didn't work") } But it prints didn't work every time. What should I do differently?

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.

My iOS app uses a Message Filter extension (via ILMessageFilterQueryHandling) and works only when run directly as the extension target. When installed normally (via TestFlight), the filter does not trigger at all — which I now believe is because iOS enforces the com.apple.developer.identitylookup entitlement at runtime. Anyone know anything about this? I put in a request for the entitlement last week but heard nothing back. Called Apple "technical" support and they had no idea what I was talking about. The documentation around this is EXTREMELY lacking in my opinion...

Hello there! So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash. So I know the "it works on my computer" sounds bad but....works on my computer and my test system. Dont know what to do since I dont know how to replicate the error. This is the rely they sent me: Issue Description The app exhibited one or more bugs that would negatively impact users. Bug description: at time of review the app’s interface went blank at launch. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.4.1 Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.

Recovery operations for signals SIGBUS/SIGSEGV fail when the process intercepts Mach exceptions.

I'm working with the FamilyControls and DeviceActivity frameworks in iOS (Swift). In my app, I collect selected apps using a FamilyActivitySelection, and I access the selected apps via selection.applicationTokens, which gives me a Set. I would like to get either the bundle identifier or the display name of the selected apps from these ApplicationTokens. I tried creating an Application instance using: let app = Application(token: token) print(app.bundleIdentifier) print(app.localizedDisplayName) However, both bundleIdentifier and localizedDisplayName are always nil. My questions are: Outside the extension (in the main app), how can I get the bundleIdentifier or display name from an ApplicationToken? Is there an Apple-recommended way to resolve a Token into something human-readable or usable? If not, what is the best practice to store or identify user-selected apps for later use? Environment: iOS 17, Swift 5, Using FamilyControls and DeviceActivity APIs. Thank you for any help!

This is a bit of a headscratcher. Xcode 16 fyi. I've written a standalone watchos app (with a stub ios app). Distributes and works perfectly over Testflight. I've submitted for app store and it passed the checks an I've released it for sale. Told my brother to use a promo code to download it and show me how it looks and report me any nuisances. He tells me there's no app neither on phone (expected) nor in watch. And he checked both the Watch ios app list and the watch. I've gone through various GPTs and they've all told me the basic troubleshooting. That his watch might not be supported (wrong, it's a watch 10 ultra with latest updates and my min supported versions are hilariously low). They've suggested that I might not have the right keys for making it standalone set, also no. They suggested that skip_install shouldn't be set to no; also wrong I think they're thinking xcode 13 and below. The stub ios app has a dependency on watchos app and also has an embed directive. I also checked the archive and saw the watchos app embedded indeed. Again, the app works perfectly fine when distributed over testflight. And AFAIK that's a release build which I know for a fact because I had a problem with not giving healthkit entitlements to release (that was another but minor headscratcher at the time, when it was working over direct xcode upload). Minor detail, I've written, test(flight)ed the app in UK and in English, my brother is in Turkey. Of course now I immediately pulled the app out of sale because I don't want people paying and getting nothing, that's gonna cause a lot of trouble. So I need any help I can get to How to debug this without exposing the app and myself: is it possible to limit the release? Obviously: what could be going wrong? How the hell did I even pass app review? Is this maybe isolated to my brother's watch? I'm more than happy to share project files and/or info.plist files(end products of them, because my plists are generated from project file).

On a device with approx 800 contacts, the sheet presented when tapping ContactAccessButton with multiple matches briefly appears (.25 seconds) before disappearing, leaving the view below in a dimmed, slightly zoomed out, non-interactive state as if a sheet were being presented. Swiping down dismisses the invisible sheet returns the underlying view to a normal state. Is there a way to avoid this? It appears possibly similar to https://developer.apple.com/forums/thread/762077 Logs (exact duplicates removed) #ContactsButton response after touch -- Should show UI LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied.

Sto cercando di creare un PDF che, a seconda del sistema operativo, utilizzi un font diverso. Visto che mi è capitato di scaricare da Internet un PDF che veniva visualizzato con con Arial su Windows e con Helvetica su iOS/macOS (anche su siti di drive, OneDrive ) vorrei creare un PDF che venga visualizzato con Arial su Windows e con Helvetica su iOS/macOS, sfruttando i meccanismi di fallback dei font di sistema (senza incorporare i font nel PDF). Ho provato a: • Scrivere il documento in Arial da Word su Windows; • Scrivere il documento in Helvetica da Word su Windows; • Disattivare l’incorporamento dei font nel salvataggio PDF su “Word”; Tuttavia, su iOS , in app come Onedrive, il PDF continua a visualizzarsi in Arial C’è un modo per: Evitare che iOS usi Arial se presente? Far sì che venga usato Helvetica come fallback? mi interessa anche capire se si può impedire ad iOS di usare Arial in lettura PDF. Qualcuno ha affrontato un caso simile o conosce un modo affidabile per ottenere questo comportamento cross-platform?
