macOS Ventura 13 beta 2 I'm coming over with a really strange issue with my cursor. It'd move toward the right-down by itself one pixel a time: right down right down It really freaked me out *laugh* I'll try attaching a video. FB submitted.

My code: struct PopoverMessage: View {     var body: some View {         VStack(alignment: .leading) {             Text("You need to launch this game at Teminal.")                 .font(.title)                 .fontWeight(.light)             Divider()             HStack {                 Text("Help me generate launch command ")                     .fontWeight(.thin)                 Image(systemName: "rectangle.portrait.and.arrow.right.fill")                     .resizable()                     .foregroundColor(.gray)                     .frame(width: 10, height: 10)             }.padding(10)         }     } } works while struct PopoverMessage: View {     var body: some View {         VStack(alignment: .leading) {             Text("You need to launch this game at Teminal.")                 .font(.title)                 .fontWeight(.light)             Divider()             HStack {                 Text("Help me generate launch command ")                     .fontWeight(.thin)                 Image(systemName: "rectangle.portrait.and.arrow.right.fill") .weigh                     .resizable()                     .foregroundColor(.gray)                     .frame(width: 10, height: 10)             }.padding(10)         }     } } don't and displays a error message Trailing closure passed to parameter of type 'CGFloat?' that does not accept a closure Here's the text in the diagnostics sheet: trailing closure passed to parameter of type 'CGFloat?' that does not accept a closure ---------------------------------------- CompileDylibError: Failed to build ContentView.swift Compiling failed: trailing closure passed to parameter of type 'CGFloat?' that does not accept a closure /Users/wangkeshijian/Documents/.myFolder/.system/TerminalAdventure/TerminalAdventure/ContentView.swift:12:37: error: trailing closure passed to parameter of type 'CGFloat?' that does not accept a closure         VStack(alignment: .leading) {                                     ^ SwiftUI.VStack:4:12: note: 'init(alignment:spacing:)' declared here     public init(alignment: HorizontalAlignment = .center, spacing: CGFloat?

I have a structure TodoItem struct TodoItem: Codable, Hashable, Identifiable {     var id: UUID = UUID()     var item: String     var done: Bool = false } And I have an array of them, and I’d like to find out a way to calculate(in a array) how many are done; that is, myArray.count / itemsDone .count is easy, itemsDone can be achieved like this: extension Array where Element == TodoItem {     var itemsDone: Double {         var done: Double = 0         for i in self {             if i.done { done += 1 }         }         return done     } } but it didn’t. struct ContentView: View { @State var todos: [TodoItem] … ProgressView(value: todos.itemsDone / todos.count) // Error My Playground won’t let me copy the error(no idea why) and my family’s iPad is in Chinese so one is Chinese. I’ll try it on Xcode and see if I can find out more. will update with the error. EDiT nor will this work: ProgressView(value: todos.itemsDone, total: todos.count)

Because of some problems I turn again to Monterey in this thread, @ekimo says that to use ad hoc you need to archive a iOS App however: what did I did wrong?

I've just bought a M2 MacBook Pro, and my Timer app is giving me strange crash logs. Here's my code: struct ContentView: View {     @State var process: Any? = nil     @AppStorage("time") var time = 0     @State var timePassed = 0     @State var timer: Timer.TimerPublisher = Timer.publish(every: 1, on: .main, in: .common)     @State var cacheSecondsString: String  = String(UserDefaults.standard.integer(forKey: "time"))     @State var startTheTimer: Bool = false     var body: some View {         ZStack {             TimerView(time: $timePassed, total: $time).padding()             VStack {                 TextField("Time...", text: $cacheSecondsString)                     .font(.system(size: 35, weight: .light, design: .rounded))                     .multilineTextAlignment(.center)                     .onSubmit {                         time = Int(cacheSecondsString) ?? time                         cacheSecondsString = String(time)                     }                     .textFieldStyle(.plain)                     .padding()                     .fixedSize()                 Button {                     withAnimation {                         startTheTimer.toggle()                     }                 } label: {                     Label(startTheTimer ? "Stop" : "Start", systemImage: startTheTimer "stop.fill" : "clock").foregroundColor(.accentColor)                 }.buttonStyle(.plain).padding()             }         }.onChange(of: startTheTimer) { start in             if start {                 process = timer.connect()             } else {                 (process! as! Cancellable).cancel()             }         }     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView()             .previewDevice("iPad Air (5th generation)")     } } When I sort of "run" the preview (pressing on the play.circle button on top of my preview and press the button the second to deactivate my timer, a crash dialog appear, the standard one macOS uses when any process crashed, but the preview didn't crash.

I tried to implement ExpressibleByIntegerLiteral to my code and it has been terrible. At last, it asked me to implement this init // Cannot find type 'Builtin' in scope init(_builtinIntegerLiteral value: Builtin.IntLiteral) { }

I had registered a seat in the online Shanghai App Accelerator lecture about Swift Charts, tomorrow in the morning I just found out that I had a class at the same time... Can I cancel my registration?

I've restarted my ColorProposer app and renamed it Chroma and the app suggests a color for a string. My main function is here: import Foundation import NaturalLanguage import CoreML func predict(for string: String) -> SingleColor? {     var model: MLModel     var predictor: NLModel     do {         model = try ChromaClassifier(configuration: .init()).model     } catch {         print("NIL MDL")         return ni     }     do {         predictor = try NLModel(mlModel: model)     } catch {         print("NIL PREDICT")         return nil     }     let colorKeys = predictor.predictedLabelHypotheses(for: string, maximumCount: 1) // set the maximumCount to 1...7     print(colorKeys)     var color: SingleColor = .init(red: 0, green: 0, blue: 0)     for i in colorKeys {         coor.morphing((ColorKeys.init(rawValue: i.key) ?? .white).toColor().percentage(of: i.value))         print(color)     }     return color } extension SingleColor {     mutating func morphing(_ color: SingleColor) {         self.blue += color.blue         self.green += color.green         self.red += color.red     }     func percentage(of percentage: Double) -> SingleColor {         return .init(red: slf.red * percentage, green: self.green * percentage, blue: self.blue * percentage)     } } struct SingleColor: Codable, Hashable, Identifiable {     var id: UUID {         get {             return .init()         }     }     var red: Double     var green: Double     var blue: Double     var color: Color {         get {             return Color(red: red / 255, green: green / 255, blue: blue / 255)         }     } } enum ColorKeys: String, CaseIterable {     case red = "RED"     case orange = "ORG"     case yellow = "YLW"     case green = "GRN"     case mint = "MNT"     case blue = "BLU"     case violet = "VLT"     case white = "WHT" } extension ColorKeys {     func toColor() -> SingleColor {         print(self)         switch self {         case .red:             return .init(red: 255, green: 0, blue: 0)         case .orange:             return .init(red: 255, green: 125, blue: 0)         case .yellow:             return .init(red: 255, green: 255, blue: 0)         case .green:             return .init(red: 0, green: 255, blue: 0)         case .mint:             return .init(red: 0, green: 255, blue: 255)         case .blue:             return .init(red: 0, green: 0, blue: 255)         case .violet:             return .init(red: 255, green: 0, blue: 255)         case .white:             return .init(red: 255, green: 255, blue: 255)         }     } } here's my view, quite simple: import SwiftUI import Combine struct ContentView: View {     @AppStorage("Text") var text: String = ""     let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()     @State var color: Color? = .white     var body: some View {       TextField("Text...", text: $text).padding().background(color).onReceive(timer) { _ in             color = predict(for: text)?.color             print(color)         }     } } But the problem of not updating the view still persists. In prints, I discovered a really strange issue: The line of print(colorKeys) is always the same.

OK I'm trying to make a sprite(model.Emmiter) that shoots balls(EnergyBalls) and the balls wont emit at the touch location: import SpriteKit import GameplayKit class Sprites {     var Emmiter: SKSpriteNode = .init(imageNamed: "Emmiter") } class GameScene: SKScene {     var model: Sprites = .init()     var Emmiter = Sprites().Emmiter     var playableRect: CGRect = .zer     var lastTouch: CGPoint = .zero     override func didMove(to view: SKView) {        Emmiter.position = CGPoint(x: size.width / 2, y: size.width/* view.frame.minY + 100 */)         print(Emmiter.position)         self.addChild(Emmiter)     }               func touchDown(atPoint pos : CGPoint) {         lastTouch = pos         let rotation = -atan2(             lastTouch.x - Emmiter.position.x,             lastTouch.y - Emmiter.position.y         )         Emmiter.run(             .rotate(                 toAngle: rotation,                 duration: 0.25             )         )         fireEnergyBall(atPoint: lastTouch)     }          func touchMoved(toPoint pos : CGPoint) {     }          func touchUp(atPoint pos : CGPoint) {     }          func fireEnergyBall(atPoint location: CGPoint) {         let EnergyBall = SKSpriteNode(imageNamed: "Energy")         EnergyBall.position = Emmiter.position         print(EnergyBall.position)                  let fly: SKAction = .run {             EnergyBall.run(.move(to: location, duration: 1))             DispatchQueue.main.asyncAfter(deadline: .now() + 1) {                     EnergyBall.un(.sequence([.scale(to: 0, duration: 0.125), .removeFromParent()]))                 }         }         EnergyBall.run(fly)         self.addChild(EnergyBall)     }     override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {         let rotation = -atan2(             touches.first!.location(                 in: self             ).x - Emmiter.position.x,             touches.first!.location(                 in: self             ).y - Emmiter.position.y         )         Emmiter.run(             .rotate(                 toAngle: rotation,                 duration: 0.25             )         )         fireEnergyBall(atPoint: touches.first!.location(in: self.view))     }          override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {     }          override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {     }          override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent?) {     }               override func update(_ currentTime: TimeInterval) {              } }

I'm trying to make an app that will let the user put their phone down for a moment. How can I keep the phone locked in the same interface for a certain amount of time, no matter what method the user uses? I've seen lots of apps doing that. (I'm using SwiftUI) PS Sorry can't think of an appropriate tag

Can I export a SwiftUI Color / UIKitUIColor / AppKit NSColor to a .clr file? How? Bonus: Can I transfer them to each other?

I have a M2, 13" MacBook Pro import Cocoa import IOKit import Foundation var blob = IOPSCopyPowerSourcesInfo() // cannot find 'IOPSCopyPowerSourcesInfo' in scope

how can I get CPU cores and type GPU core and type storage and memory current wifi, recieved&sent packages etc in swift on macOS?

I want to get battery level, estimated remaining time, battery health...etc via IOPSCopyPowerSourcesList Not sure how I'm not experienced with pointers...     func updateBatteryView() {         let battery = IOPSCopyPowerSourcesInfo().takeRetainedValue()         let info = IOPSCopyPowerSourcesList(battery).takeRetainedValue() // Now what?     }

I'm trying to get the memory usage of the entire system. // referance: https://www.jb51.cc/iOS/590624.html public func memsize() -&gt; UInt64 {     var taskInfo = mach_task_basic_info()     var count = UInt32(MemoryLayout&lt;mach_task_basic_info&gt;.size)     let kerr: kern_return_t = withUnsafeMutablePointer(to: &amp;taskInfo) {         $0.withMemoryRebound(to: integer_t.self,capacity: 1) {             task_info(mach_task_self_,task_flavor_t(MACH_TASK_BASIC_INFO),$0,&amp;count)         }     }       if kerr == KERN_SUCCESS {         return taskInfo.resident_size     }     return 0 } not working, apparently. When my system uses 15 GB it shows it's below 1 GB. Do anyone have other ways to get memory usage of the device (better macOS)
