Im trying to make a an app that calculates the WPM - ios

Question

Im trying to make a an app that calculates the WPM. In the end of the game I would like to use a timer to stop the app after 60 seconds. I can't figure out how to stop it. I'm trying to stop it with conditional statement. But I don't know how to implement it with SwiftUI. If anyone had any other ideas that would be great.
import SwiftUI
struct ContentView: View {
#State var userInput = ""
#State var modalview = false
#State var getstarted = false
#EnvironmentObject var timerHolder : TimerHolder
var body: some View {
ZStack() {
modalView(modalview: $modalview, userInput: userInput)
}.sheet(isPresented: $modalview) {
modalView(modalview: self.$modalview)
}
}
}
struct modalView : View {
#ObservedObject var durationTimer = TimerHolder()
#Binding var modalview : Bool
#State var userInput: String = ""
var body: some View {
VStack{
Button(action: {
self.modalview = true
}) {
TextField("Get Started", text:$userInput)
.background(Color.gray)
.foregroundColor(.white)
// .frame(width: 300, height: 250).cornerRadius(20)
}
Text("\(userInput.count)")
if durationTimer == 60 {
.alert(isPresented: $showAlert) {
Alert(title: Text("Reminder"), message: Text("You wrote"), primaryButton: .default(Text("Yes"), action: { self.presentationMode.wrappedValue.dismiss() })
, secondaryButton: .cancel(Text("No")))
}; else {
}
}
}
}
class TimerHolder : ObservableObject {
var timer : Timer!
#Published var count = 0
func start() {
self.timer?.invalidate()
self.count = 0
self.timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true) {
_ in
self.count += 1
print(self.count)
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
}

I changed some codes to give you a clue.
struct ContentView: View {
#State var userInput = ""
#State var modalview = false
#State var getstarted = false
#EnvironmentObject var timerHolder : TimerHolder
var body: some View {
ZStack() {
modalView(modalview: $modalview, userInput: userInput)
}.sheet(isPresented: $modalview) {
modalView(modalview: self.$modalview)
}
}
}
struct modalView : View {
#ObservedObject var durationTimer = TimerHolder()
#Binding var modalview : Bool
#State var userInput: String = ""
var body: some View {
VStack{
Button(action: {
self.modalview = true
}) {
TextField("Get Started", text:$userInput)
.background(Color.gray)
.foregroundColor(.white)
// .frame(width: 300, height: 250).cornerRadius(20)
}
Text("\(userInput.count)").alert(isPresented: self.$durationTimer.count) {
Alert(title: Text("Reminder"),
message: Text("You wrote"),
primaryButton: .default(Text("Yes"), action: { self.presentationMode.wrappedValue.dismiss()
print(123)
})
,
secondaryButton: .cancel(Text("No")))
}
}
}
}
class TimerHolder : ObservableObject {
var timer : Timer!
#Published var count = false
init(){
self.start()
}
func start() {
self.timer?.invalidate()
self.count = false
self.timer = Timer.scheduledTimer(withTimeInterval: 60, repeats: true) {
_ in
self.count = true
print(self.count)
}
}
}
