I'm quite new to SwiftUI and can't get around this error. I'm trying to use two @State variables (isGlobal and dataType) in another array within the same initializer. I keep getting the error: "Cannot use instance member 'dateType' within property initializer; property initializers run before 'self' is available" and "Cannot use instance member 'isGlobal' within property initializer; property initializers run before 'self' is available" This is the code at the beginning of the view: struct Home : View { @State var dateType : Int @State var isGlobal = true @State var dailyVax = [ DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 6))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 6))", show: true), DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 5))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 5))", show: false), DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 4))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 4))", show: false), DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 3))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 3))", show: false), DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 2))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 2))", show: false), DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 1))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 1))", show: false), DailyVaccinations(day: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: false, dayCt: 0))", value: "\(showData(tabType: isGlobal, date: dateType, dataType: 4, change: true, dayCt: 0))", show: false), ] var body: some View { ... Here's the [DailyVaccinations] struct: struct DailyVaccinations : Identifiable { var id = UUID().uuidString var day : String var value : String var show : Bool } And here's the code that actually uses the "dailyVax" array: ForEach(dailyVax.indices,id: \.self){i in GraphView(data: dailyVax[i], allData: dailyVax) .onTapGesture { withAnimation{ for index in 0..<dailyVax.count{ dailyVax[index].show = false } dailyVax[i].show.toggle() } } if dailyVax[i].value != dailyVax.last!.value { Spacer(minLength: 0) } } ... If anyone can help me solve this issue it would be greatly appreciated! thank you
