I have this code where I want to change the appearance of the text color based on a user saying yes or no. I tried creating a var like "var color: Color" in the if statements however, it kept saying that it dit not conform to the view. How can I make conditional code effectively instead of having to copy past every thing again and again?
You could use a computed property that returns a Color based on the user's reserved property:
struct User {
var reserved : String
var name : String
}
struct ContentView: View {
@State private var user = User(reserved: "waiting", name: "Bob")
var colorForReserved : Color {
switch user.reserved {
case "yes":
return .green
case "no":
return .red
case "waiting":
return .orange
default:
return .black
}
}
var body: some View {
HStack {
Image(systemName: "person.crop.circle.badge.checkmark")
Text(user.name)
}
.foregroundColor(colorForReserved)
}
}
Note that you can avoid the default if you changed reserved to an enum rather than a String
