value being constant in swiftUI - ios

Question

I am sorry im not sure that the title makes sense but if u read, im sure u will understand my problem. I have declared a variable #State var timetext: Int32 in the file CreatingWorkout, with a textfield TextField("5000, 100 etc", value: $timetext, formatter: NumberFormatter()) When i go to the createWorkoutView file and try to present it with the sheet, it wants me to give a value to timetext. However, when i provide a value with the textfield it stays constantly value given when calling with the sheet. I will attach a video here for you to see.
CreatingWorkout.swift :
struct CreatingWorkout: View {
#State var workoutTitle: String
#State var desc: String
#State var timetext: Int32
#State private var iconColor = Color.black
#State var displayWorkout: String = ""
#Environment(\.dismiss) var dismiss
#Environment(\.managedObjectContext) private var viewContext
private func saveWorkout() {
do {
let workout = Workout(context: viewContext)
workout.title = workoutTitle
workout.time = timetext
workout.icon = displayWorkout
workout.descriptionn = desc
try viewContext.save()
} catch {
print(error.localizedDescription)
}
}
CreateWorkout.swift :
import SwiftUI
struct CreateWorkoutView: View {
#State private var showingCreateWorkout = false
#State var timetext: Int32 = 0
var body: some View {
NavigationView {
VStack {
VStack(alignment: .center, spacing: 20) {
Text("Fitzy")
.font(.largeTitle)
.fontWeight(.bold)
Text("Create your first Workout")
.font(.title3)
.foregroundColor(.gray)
Button {
showingCreateWorkout.toggle()
} label: {
Image(systemName: "plus")
.font(.largeTitle)
.foregroundColor(.white)
.padding()
.background(
RoundedRectangle(cornerRadius: 10, style: .continuous)
.foregroundColor(Color("AccentColor"))
.frame(width: 50, height: 50)
)
}.sheet(isPresented: $showingCreateWorkout) {
CreatingWorkout(workoutTitle: "", desc: "", timetext: timetext)
}
}
}.navigationTitle("Create Workout")
}
}
}
struct CreateWorkoutView_Previews: PreviewProvider {
static var previews: some View {
CreateWorkoutView()
}
}

Answer 1

as mentioned in the comments, you need a #State property to pass the value
that you type in your TextField to the sheet with CreatingWorkout. Try something like this:
struct CreatingWorkout: View {
#State var workoutTitle: String
#State var desc: String
#State var timetext: Int32
// ....
var body: some View {
Text("\(timetext)")
}
}
struct CreateWorkout: View {
#State var showingCreateWorkout = false
#State var timetext: Int32 = 0 // <-- here
var body: some View {
VStack {
TextField("type a number", value: $timetext, format: .number).border(.red) // <-- here
Button {
showingCreateWorkout.toggle()
} label: {
Image(systemName: "plus").font(.largeTitle).foregroundColor(.red).padding()
.background(
RoundedRectangle(cornerRadius: 10, style: .continuous)
.foregroundColor(Color("AccentColor"))
.frame(width: 50, height: 50)
)
}.sheet(isPresented: $showingCreateWorkout) {
CreatingWorkout(workoutTitle: "", desc: "", timetext: timetext) // <-- here
}
}
}
}
