Hello, how do I remove the background lines of a chart and just show the BarMark? import SwiftUI import Charts struct myView: View { var body: some View {  Chart{   BarMark(x: .value("o", 5), y: .value("m", "Duration: 5m"), width: 7) .foregroundStyle(.orange) BarMark(x: .value("o", 7), y: .value("m", "Intervals: 7"), width: 7) .foregroundStyle(.teal)       } } }

Good day, I get an error “The requested index was outside the bounds of the array.” How do I solve it? Here is my code: import SwiftUI struct ContentView: View {     @State var first: [String] = ["Hello Jamie!","Hello John!","Hello Justin!"]     @State var dates: [String] = ["21","22","23"]     @State var numberIam: Int = 0     var body: some View {         VStack {           ForEach(first, id: \.self) { item in                 Text(item)                     .onAppear{                         numberIam = numberIam + 1                     }                 Text(dates[numberIam])                  }              }     } } Thank You!

Does revenueCat SDk qualify for any exemptions provided in category 5 part 2 of the US export administation regulations? I’m getting asked this in App Store Connect, it also says: You can select Yes for this question if the encryption of your app is: (a) Specially designed for medical end-use (b) Limited to intellectual property and copyright protection (c) Limited to authentication, digital signature, or the decryption of data or files (d) Specially designed and limited for banking use or “money transactions”; or (e) Limited to “fixed” data compression or coding techniques   I'm sure whether I should check this since revenueCat does use encryption. Thank You, Jamie

Good day, How do I repeat the arrays but in one ForEach loop or is there any other way of repeating the arrays in the order dates then intervals then durations then times, I need repeated blocks of multiple arrays. Here is my code: struct ContentView: View {     @State var dates: [String] = ["21 Jun","22 Jul","12 Aug"]     @State var intervals: [String] = ["8","2","5"]     @State var durations: [String] = ["10m","12m","7m"]     @State var times: [String] = ["45s","65s","12s"]     var body: some View {         VStack {             ForEach(Array(zip(dates, durations)), id: \.0) { item in                  VStack{                 Text(item.0)                     .padding()                 Text(item.1)                         .padding()                 }                            }             ForEach(Array(zip(intervals, times)), id: \.0) { item in                  VStack{                     Text(item.0)                         .padding()                     Text(item.1)                         .padding()                 }             }             .offset(y: -206)         }     } }              Here is the order I need it to be repeated in: Thank You
