Hi everyone I'm new to SwiftUI and i try to make a simple app for random choices,So when you create a list choices that will turn to a Spin-WheelView.For now, I face two problems: First. I don't know how save Angle and Array to UserDefaults; Second: I don't know to connect choices view to spin-wheel view. Any helps i will appreciate it! thank you all. My model: import SwiftUI struct ChooseModel: Identifiable, Codable {     var id = UUID()     var decision: String     var choices: [String]     // i try to create Angle and [Colors] in my model,     // but they don't confirmed Codable, i don't know how to save them to User defaults. //    var startAngle: Angle //    var endAngle: Angle //    var colors: [Color] } Model View import SwiftUI class ChooseModelView: ObservableObject {     @Published var models = [ChooseModel]() {         didSet {             let encoder = JSONEncoder()             if let encoded = try? encoder.encode(models) {                 UserDefaults.standard.set(encoded, forKey: "models")             }         }     }     init() {         if let items = UserDefaults.standard.data(forKey: "models") {             let decoder = JSONDecoder()             if let decoded = try? decoder.decode([ChooseModel].self, from: items) {                 self.models = decoded                 return             }         }         self.models = []     } } My View: struct ChooseView: View {          @ObservedObject var chooseMV = ChooseModelView()     @State private var showingAddView = false          var body: some View {         NavigationView {             List {                 ForEach(chooseMV.models) { item in                     // Use NavigationLink to Each WheelView                     HStack {                         VStack(alignment: .leading) {                             Text(item.decision)                                 .font(.title3)                             HStack {                                 ForEach(item.choices, id: \.self) { choice in                                     Text("\(choice),")                                         .foregroundColor(Color.green)                                 }                             }                         }                         Spacer()                     }                                      }.onDelete(perform: remove)             }.navigationTitle("iChoose")                 .navigationBarItems(leading: EditButton(), trailing: Button(action: {                     self.showingAddView = true                 }, label: {                     Image(systemName: "plus")                 }))                 .sheet(isPresented: $showingAddView) {                     AddView(chooseMV: self.chooseMV)                 }         }     }     func remove(at offsets: IndexSet) {         chooseMV.models.remove(atOffsets: offsets)     } }

Hi, guys i got errors from my View like below : Is anyone who can help me to fix it? My model like:     var id = UUID()     var decision: String     var choices: [String]     var startAngle: Angle     var endAngle: Angle           @CodableColor var color: UIColor     struct Angle: Codable, Equatable {         var degrees: Double     } } My model view like: import SwiftUI class ChooseModelView: ObservableObject {     var midRadians: Double {         return Double.pi / 2.0 - (model.startAngle.degrees + model.endAngle.degrees) * .pi / 180 / 2.0     }     @Published var model = ChooseModel(decision: "What to eat tonight?", choices: ["Sushi", "Ramen", "Korean BBQ", "Chinese"], startAngle: ChooseModel.Angle(degrees: 0.0), endAngle: ChooseModel.Angle(degrees: 90.0), color: UIColor.green) My view like :                     let width: CGFloat = min(geometry.size.width, geometry.size.height)                     let height = width                     let center = CGPoint(x: width * 0.5, y: height * 0.5)                     path.move(to: center)                     path.addArc(                         center: center,                         radius: width * 0.5,                         startAngle: Angle(degrees: -90.0) + chooseMV.model.startAngle,                         endAngle: Angle(degrees: -90.0) + chooseMV.model.endAngle,                         clockwise: false)                     path.closeSubpath()                 }

Hi guys, I'm new to SwiftUI and I'm still working on my spinning wheel. For now I wanna show people the results on screen by Text("(Array[index])"). the question is i know the random rotation degrees but i don't know how to transfer it to that "result angles" index :P ,Any help I will appreciate it ! I use Path to draw the wheel: var slices: Array<OneChance.OneChanceData> {         let sum = Double(newChoices.count)         var endDeg: Double = 0.0         var tempSlices: [OneChance.OneChanceData] = []         for (color, text) in zip(colors, newChoices) {             let degrees: Double = Double(360 / sum)                          tempSlices.append(OneChance.OneChanceData(startAngle: Angle(degrees: endDeg), endAngle: Angle(degrees: endDeg + degrees), text: text, color: color))             endDeg += degrees         }         return tempSlices     } The spinning wheel view: ForEach(0..<chanceVM.newChoices.count) { i in                         EachSliceView(chanceData: self.chanceVM.slices[i])                     } I use onTapGesture to get random wheel spinning degrees: .onTapGesture {                             self.chanceVM.showResult = false                             self.chanceVM.rotateDegree = 0.0                             playSound(sound: "wheelSpinning13s", type: "mp3")                             self.chanceVM.allowToTapAgain = false                             withAnimation(Animation.easeOut(duration: 13.0)) {                                 self.chanceVM.rotateDegree = Double.random(in: 5400.0...7200.0)                             }                             print("\(chanceVM.rotateDegree)")                             print("\((Int(chanceVM.rotateDegree) % 360))")                             print("\((Int(chanceVM.rotateDegree) % 360)/(360/chanceVM.newChoices.count))")                             self.chanceVM.delayText()                             self.chanceVM.delayTap()                         } So how can i get the index after random spinning degrees?

—Hi guys, Is anyone can share any suggestions for me? I have this random shoinning wheel and the spinning speed is controlled by .timingCurve( beginning very fast at end get slowly) So I want to make sound effects for this action.But I don’t know how. Thank you in advance!

Hi, guys I have a array like this: [ [icon: "A", amount: 11], [icon: "B", amount: 10], [icon: "A", amount: 15], [icon: "B", amount: 13], [icon: "C", amount: 5] ] Right now I only can show them in list one by one like: icon: "A", amount: 11 icon: "B", amount: 10 icon: "A", amount: 15 icon: "B", amount: 13 icon: "C", amount: 5 How can i show them in a List like: icon: "A", amount: 26 icon: "B", amount: 23 icon: "C", amount: 5 I appreciate it for any help and suggestions !

I ran this app on my IPhone 12 and screen shots like below: Any helps will appreciate it.
