Xcode and Reading documents from a URL connection.
I have an Xcode app where currently txt files in the project display text data as a list. I can search through the lists and have buttons that will swap between different lists of information that you can look through. The next task is I have URL connections to docx files on a SharePoint site. I am trying to use an URLsession function to connect to the URL links to download the documents to the document directory then have the application read the doc information to then be displayed as the txt info would. The idea is that the docx files are a type of online update version of the data. So when the app is used and on wifi, the app can update the list data with the docx files. I have code set up that should access the URL files but I am struggling to figure out how to read the data and access from this Documents directory. I have been looking online and so far I am at a loss on where to go here. If anyone can help or provide some insight I would greatly appreciate it. I can try and provide code samples

Unable to create SwiftUI previews in Xcode 26 for iOS 15.5

Tip always displayed with TipKit
Why a TipKit configured with a weekly frequency, on the following example, when the app is launched on the View1, the tip is displayed. I thought that going to View2 and come back to View1 should not redisplayed the tip (at least until one week). What do I miss? import SwiftUI import TipKit struct FavoriteLandmarkTip: Tip { var title: Text { Text(Save as a Favorite) } var message: Text? { Text(Your favorite landmarks always appear at the top of the list.) } var image: Image? { Image(systemName: star) } } @main struct LandmarkTips: App { var body: some Scene { WindowGroup { TabView { View1() .tabItem { Label(View1, systemImage: house) } View2() .tabItem { Label(View2, systemImage: house) } } .task { do { // uncomment to reset all tips status // try? Tips.resetDatastore() try Tips.configure([ .displayFrequency(.weekly), .datastoreLocation(.applicationDefault) ]) } catch { print(Error initializing TipKit (error.localizedDescription)) } } } } } struct View1: View { let favoriteLandmarkTip = FavoriteLandm

Malware warnings on properly notarized apps
Hello, I've been developing a mac app built with Electron Builder. In August, I was successfully notarizing my app and able to send it to testers without them receiving a malware warning. I took a two month break. When I came back in October, I am not able to distribute my app without the malware warning. I can't for the life of me figure out what I could be missing, unless my developer account was flagged by Apple for some reason. All the diagnostics I run on my app package show that it is properly signed, notarized, and stapled. Here are some diagnostics I have run on the app: Command: codesign -dv --verbose=4 /Volumes/Form Desktop 1/Form.app Output: Executable=/Volumes/Form Desktop 1/Form.app/Contents/MacOS/Form Identifier=co.Form.desktop Format=app bundle with Mach-O thin (arm64) CodeDirectory v=20500 size=763 flags=0x10000(runtime) hashes=13+7 location=embedded VersionPlatform=1 VersionMin=720896 VersionSDK=917504 Hash type=sha256 size=32 CandidateCDHash sha256=cedcaef933c003c01b4d9ef69

Reply to StoreKit Config file Options Grayed Out
It does seem buggy. In case you haven't found out already, for the grayed out failure options, it appears that the file may be missing entries in the _storeKitErrors array and the editor won't create them. Edit the config file JSON (Open As -> Source Code) and replace the empty _storeKitErrors array with the following. Seems to fix it for me. _storeKitErrors : [ { current : null, enabled : false, name : Load Products }, { current : null, enabled : false, name : Purchase }, { current : null, enabled : false, name : Verification }, { current : null, enabled : false, name : App Store Sync }, { current : null, enabled : false, name : Subscription Status }, { current : null, enabled : false, name : App Transaction }, { current : null, enabled : false, name : Manage Subscriptions Sheet }, { current : null, enabled : false, name : Refund Request Sheet }, { current : null, enabled : false, name : Offer Code Redeem Sheet } ]

Reply to Installer packages are failing to install on macOS26.1
[quote='866297022, premak, /thread/806222?answerId=866297022#866297022, /profile/premak'] Could you please help on how to call preinstall and postinstall scripts in the packages created using productbuild command? [/quote] I’m hardly an installer expert, but my understanding is that: You pass a components property list path to pkgbuild via the --component-plist argument. You reference your scripts from there via the BundlePreInstallScriptPath and BundlePostInstallScriptPath properties. See the Component Property List section within the pkgbuild man page. You then pass that package to productbuild to build the final signed flat package. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

Reply to Commands for MacOS which gives similar information as "lsappinfo" and "system_profiler SPApplicationsDataType" for other Mach-O binaries
From the perspective of a security product: You can’t trust lsappinfo or any API layered on top of Launch Services. It’s possible for apps to be on the system that are not known to LS. Given an app bundle, you can’t find all the Mach-O images within that bundle other than by walking the file system hierarchy. That second point warrants further explanation. While Apple has clear guidelines about where to put code within a bundle — see Placing content in a bundle — many (many many) third-party apps bend those guidelines. For example, it’s very common to see entire Java runtimes placed within Contents/Resources. APIs like NSBundle assume that the bundle is structured correctly, and thus won’t be useful in a security product that can’t trust the bundle’s structure. Finally, there’s your question about dynamic library versions. There are no good APIs for that, but the Mach-O on-disk image structure is reasonably well defined [1] and thus you can open the file and read the info you need: Identify

Occlusion issues in Immersive Space - Breaking User Input Interaction
I'm developing a custom gesture-based visionOS project that uses hand tracking with collision detection spheres on fingers to register user interactions through collision components. I'm experiencing a critical occlusion issue where collision detection spheres are intermittently occluded by the background/depth buffer, causing fingers to pass through the 3D model entities without registering interactions. Detailed Description: I have added 3D entities in an immersive scene with collision spheres attached to fingers for detecting user interactions. Each sphere has: CollisionComponent with sphere shape Proper collision masks and groups configured Real-time position updates from hand joint transforms Each entity has: InputTarget components to register collisions The Issue: When users move their fingers to the entity to interact, some collision spheres (particularly on the pinkie and ring fingers) become occluded and pass directly through the 3D model without triggering collision events. Meanwhile, other fingers

Reply to Wakes (CalendarDate), although related UI settings are off
Hi Quinn! Many thanks for your reply and sorry for the double thread. I hadn't realized that the first one was waiting for approval, so it wasn't showing up in my activity list. Anyway, I came here from Apple Support Community, where I had a pretty bad experience regarding inappropriate behavior of senior members on a similar, but already resolved issue (TravelEngine and OSAnalytics setting wake alarms, while relevant UI settings were off). Long story, but basically I got a last warning there because I kept addressing the fact that instead of receiving answers to my actual question, senior members were gaslighting me, insinuating that I had somehow altered system files and even straight out lied about what was written and then edited/removed posts in order to try and support the lies. I already reported the behavior to Apple, but I'd rather not post anything there anymore. To answer your question: no, I'm not building any product, I am simply trying to find a way to stop automatic dark wakes, if that

Reply to NEPacketTunnelProvider performance issues
Packet tunnel providers run in user space and that has some some unavoidable performance impact [1]. I don’t have solid number of that because it’s hard to isolate from the performance impact of the tunnel itself. However, bouncing over to another daemon is obvious not going to improve things, no matter how efficient your IPC is. Is there an overriding reason you don’t do this work in your sysex? It is more-or-less a launchd daemon in its own right. Even if you can’t make this change in your main product, it’d be worth trying to hack together a prototype, because it would allow you to rule out your IPC as a source of the performance loss. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com [1] At least until we get a direct path from the user-space networking stack to your packet tunnel provider, which isn’t currently a thing.

Are you build a product for macOS where this is relevant? If so, can you explain more about the background to that. If not, I suspect that the Apple Developer Forums aren’t the right place for you, and I encourage you to pop on over to Apple Support Community, run by Apple Support.

Reply to Performance degradation of HTTP/3 requests in iOS app under specific network conditions
Thanks for the detailed explanation! I tried your approach with the QUIC diagnostics, and while the container downloads successfully without the colon issue you mentioned, I encountered some inconsistencies with the logging itself. The logs didn't write immediately, and I only managed to get them working once—I'm still not entirely sure what I might have been doing wrong. The qlog revealed significant packet loss, which seems to be the direct cause of the issues. However, it's unclear why this specifically affects QUIC in our case, as other QUIC-based services work flawlessly from the same device (I've verified this with Wireshark profiling). Regarding the usesClassicLoadingMode property in iOS 26: I tested disabling it to switch to the modern HTTP engine but observed no improvement. Interestingly, while the spec mentions support starting from iOS 18.4+, enabling HTTP3 on iOS 18.7 resulted in requests hanging until timeout. Any additional insights would be greatly appreciated!
