Overview

Is there a way to create a 3D animation that occurs in the same exact locations each time it runs. From what i understand from the anchors that when the app launches it detects a flat surface and plays the animation there. I’m looking mg for it to occur in the same position each time.

Hey I wanted to ask you how I can implement the Swipe back Gesture in Swift. So I want that the user start at the Home View Controller and then he can tap on the "happy number Rechner"-Button and then the calculator View Controller appears. Like the same way with the transitions in the Settings App of iOS. And if you swipe left the Home View should appear again.

Hi, quartz debug 4.2 (from the "Additional Tools for Xcode 14.2") doesn't show most tracking rectangles on macOS Ventura. I tested this on two Macs. Any solution to debug tracking areas on this OS? Thanks.

Trying to locate the sample code from the WWDC video on the updated PDKKit for iOS 16+ with overlay functionality. Looks like the only references are pointing to an older 2017 project. Is this sample code available anywhere? Here is the link to the announcement video: https://developer.apple.com/videos/play/wwdc2022/10089/

an AVDepthData class method converting(toDepthDataType: kCVPixelFormatType_DepthFloat16) does not work. let depthData = photo.depthData depthData.converting(toDepthDataType: kCVPixelFormatType_DepthFloat16) let ddType = depthData.depthDataType ddType value is 1751411059 which means kCVPixelFormatType_DisparityFloat16. How do I get the DepthFloat16 format data?

When altool notarizes my apps, I get an email confirmation to my Apple ID email address. This does not happen with notarytool. Is this expected behavior?

Hi community, I'm a new iOS developer and I'd like to develop application using Room Plan API/UIKit/ARKit. Currently I'm able to : Scan room Detect room objects (in console logs) Export data file (.usdz) from scanned room using the default UIViewController from UIKit. But now I would like to add my custom display when objects are detected. I google it but don't found anything around it. I think I have to use this method from RoomPlan API to display category of detected objects. func captureSession(_ session: RoomCaptureSession, didUpdate room: CapturedRoom) { RoomPlan can't display custom data right ? If yes, I have to use ARKit or UIKit in this method to add custom text to the frame of the detected object ? I can share code if necessary. Thanks in advance, Goat.

Hello Guys, I am writing a program using PencilKit. Yesterday, everything worked fine with this line: @State var pencilStyle: PKInkingTool.InkType = .monoline But today, i am getting this Error: Type 'PKInkingTool.InkType' has no member 'monoline'" When I started Xcode Today, it downloaded a new Simulator for iOS 16.2. How can I fix this issue? I can't use my Projekt without fixing this... Thanks in advance <3

Hello, I am new to Swift and have a specific requirement needing to be implemented through the VideoToolbox API. I am using MethodChannel() from Flutter SDK to invoke Swift functions. I need access to the HW video decoder and the plan is to receive encoded frames from flutter application, decode with VideoToolbox API, then return the decoded image back through the MethodChannel(). I am having trouble checking if the session succeeds in decoding a frame. The callback given to VTDecompressionSessionDecodeFrame() via the VTDecompressionOutputCallbackRecord class may only return a void. However, this callback recieves as argument the decoded image buffer and status, which I have no way of accessing at the moment; this is essentially my problem. I tried some method such as creating a variable at a higher level scope but I get compiler error A C function pointer cannot be formed from a closure that captures context. It was also quite frustrating that I simply cannot get the base address of a variable like in C/C++ so I can perform memcpy(), but that is another topic. So my question is, how may I return/access data within a closure that may only return void? Are there any helpful classes to facilitate communication between the closure and function calling VTDecompressionSessionDecodeFrame(). My idea would be to have the calling function wait until the value of the image buffer or status changes. This doesn't sound like a good implementation but it's only what I can think of at the moment. Any help would be appreciated. Thank you.

Anyone else have this problem where the DeviceActivityCenter is silently failing/hanging on startMonitoring? No error caught but the code won't progress, and the intervalDidStart never runs.

How to hide keyboard on tap outside of TextField in SwiftUI? SwiftUI on iOS 16 Within a List a Section with a TextField I want to dismiss the keyboard if I tap outside the focused TextField. I thought, searched and found no solution the does this correctly. Either it does not dismiss in all cases or it does dismiss while clicking into the TextField, too. What is the best or a good solution for this problem?

I've been working on the open source code of the Signal-iOS project recently. I want to add some functionality to Signal. But I found that I can't add "com.apple.developer.pushkit.unrestricted-voip" in entitlements. How can I solve this problem please.

Hello, I am getting reports from some users that one of my apps is behaving weirdly when: Stage Manager is enabled with an external display connected (presumably with app windows on the external display). I would like to debug this issue. However, I do not have an iPad compatible with Stage Manager. On the Simulator in Xcode, I can run an iPad with Stage Manager (good) and pretend to connect an external display (good), but I cannot move windows to the external display, so I cannot reproduce the issue. What can I do? (the app uses SwiftUI and UIScene. It does work with multiple windows on standard iPads, it does work with StageManager on the iPad simulator).

Greetings, I'm discovering Xcode program for the first time and found on YT one training video how to create logging screen which I could try to code. But in 3/4 of the video I had met with a problem 🙈 while writing NavigationLink command. The command was written same way as was in tutorial video, but in this version of Xcode popped up attention message : " 'init(destination:isActive:label:)' was deprecated in iOS 16.0: use NavigationLink(value:label:) inside a NavigationStack or NavigationSplitView". Have you any idea how to correctly write for actual version of IOS? I'll look 4wrd for your suggestions. 🙂 Sincerly, Jim

When I delete a tester from the TestFlight panel, he is not actually deleted, just marked as deleted. As a result, people who have already exited the test cannot be truly deleted, and new testers cannot join. All testers is 8056. Tester deleted is 1944. After I delete 2 testers，all testers is 8054, tester deleted is 1946. When new testers try to join, they get error：This beta is fully booked.
