column

I am exploring ARKit and SceneKit, but I am not sure if what I want to do is possible. In App1: Run an ARKit session using configuration.sceneReconstruction = .mesh I am rending the mesh in func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) and func renderer(_ renderer: SCNSceneRenderer, didUpdate node: SCNNode, for anchor: ARAnchor) and the mesh appears correct I have set up a button that does the following: Capture the mesh to an .obj file (based off the excellent answer in here) Capture a snapshot (SCNView snapshot) Store the AR Camera Transform Store the AR SCN View Point Of View Projection Transform Storing the transforms in a CSV, and taking care to ensure I restore them in column major order. In App2: Load the geometry from the .obj file into SCNNode, do not apply any transform to it, apply a wireframe to it so I can visualise it Add a camera and apply the 2 saved transforms (AR Camera Transform and then AR SCN View Point Of View Projection Transform Set th

Hi, I'm trying to change the behaviour of Command-click on Code under Xcode > Settings > Navigation to display the Action menu to use features such as Add Column Breakpoint. But unfortunately the option Selects Code Structure is not visible when unfolding for different options, the only choices are Jumps To Definition and Multi Cursor. I have seen other users having Selects Code Structure instead of Multi Cursor, I really wonder how Multi Cursor got there 😅 . Is there a way to make Selects Code Structure visible and selectable? Any help would be appreciated. I'm running Xcode 15 on macOS Sonoma.

I recently switched from Windows to a macbook air m2 with 16gbs ram. It was all great in the beginning and now after a week it when using devtools in Chrome, Brave, Firefox.. the helper (renderer) process goes up to 150% in the cpu (%) column and there's 2 of these at 100%+ each. I tried running the same thing on my Windows machine and it runs normally. On the mac it doesnt even load the autofill for css properties, it lags way too much, makes the whole system unusable and hot. My windows machine is not even close to match the performance of the m2. I am not sure what's wrong, any suggestions? I disabled hardware acceleration, I have no extensions (even disabled the google docs offline extension), system is up to date, chrome is up to date, cleared storage and cache. I feel like I am out of options.

I'm trying to use the new (announced at WWDC 2023 and available in iOS 17 and macOS 14) API to observe scroll position of SwiftUI ScrollView. I have the following view, but I can't make it work correctly. That is, using the scrollPosition(id:anchor) view modifier makes the scroll view go nuts. At some point, and in some cases even at the very beginning, the scroll view just starts jumping and is stuttering when trying to scroll. See the screen recording here: https://mastodon.social/@tomkraina/111249340792812592 The code: struct ContentView: View { private var itemSize: CGSize = .init(width: 50.0, height: 50.0) // Annotated as @State to create the sections only once @State private var sectionData = makeSections() // Tracking scroll position @State private var currentItemID: MyIdentifier? var currentItemDescription: String { self.currentItemID?.stringId ?? nil } var body: some View { VStack { // 1. Scroll View ScrollView(.vertical) { LazyVGrid( columns: [.init(.adaptive(minimum: self.itemSize.width),

This may be trivial to some but I just would like to know if you can copy an array to a new array and change the type of the data for each column of elements? I have loaded a file into an array as String data as I can't seem to do it any other way (i.e. as another type) I now want to convert some of the columns to a different type in possibly a new array. I have an array full of string data and I would like to convert it to Double, or some Int, data so that I can easily do my calculations. I would appreciate as much info as possible as I am relatively new to SwiftUI and Xcode. Many thanks, D Norris

Hello everyone, I am experiencing a very weird issue. I have a simple relationship between 2 models, that occasionally starts crashing the app, with the following error: error: : Attempting recovery from error encountered during addPersistentStore: 0x282523c60 Error Domain=NSCocoaErrorDomain Code=134110 An error occurred during persistent store migration.

I'm confused by the stats on the TestFlight builds screen. See below. There are more crashes than sessions. So the definition of session can't quite be what I thought. Does a session have to last more than a certain amount of time to be included? Do sessions that end in a crash not count as sessions? Do multiple invocations within a short period of time count as a single session? The number of sessions falls over time. I.e. once I have released a new version, the reported Sessions numbers for older versions slowly fall. Maybe as soon as a user has used version N+1, all their sessions for version N are removed from the stats? The invites column is clearly the same for every version, while it should have been slowly increasing. Is there any value in these numbers?

I have a two column LazyVGrid inside a ScrollView and want to animate the removal of an item when the user taps on it. This seems to work fine when either the top or the bottom of the grid is visible (i.e. scrolled all the way up or down) and when removing an item doesn't change the number of rows. But when you scroll down a bit and remove an item when it results in the number of rows changing, it flashes as it's rendering. Minimally Reproducible Example import SwiftUI extension Color { static var random: Color { let red = Double.random(in: 0...1) let green = Double.random(in: 0...1) let blue = Double.random(in: 0...1) return Color(red: red, green: green, blue: blue) } } struct ContentView: View { @State private var items: [Int] = Array(1...50) let columns = [GridItem(.flexible(), spacing: 2), GridItem(.flexible(), spacing: 2)] var colorDictionary: [Int: Color] = [:] init() { for i in 1...50 { colorDictionary[i] = Color.random } } var body: some View { ScrollView { LazyVGrid(columns
