SwiftUI: Is there any solution to clear value in DatePicker? - swift

Question

I am finding a solution to clear value of a DatePicker in SwiftUI. I tried and it's not success. Please check:
struct EditProfileView: View {
#State var birthDate = Date()
var body: some View {
Form {
Section (header: Text("Birth day")) {
DatePicker(selection: $birthDate, in: ...Date(), displayedComponents: .date) {
Text("Select a date")
}
HStack {
Text("You were born in \(birthDate, formatter: dateFormatter)")
.font(.subheadline)
.foregroundColor(Color.gray)
Spacer()
Button(action: {
self.clearDate()
}) {
Text("Clear")
}
}
}
}
}
func clearDate () {
self.$birthDate = nil
}
}
This line of code is not work:
self.$birthDate = nil
I think because of Date type cant not leave nil but I cant find a solution to handle with it

Answer 1

Set the birthDate (not $birthDate) to the following, which will default back to the current date:
self.birthDate = Date()

Answer 2

You can create a Binding from Date?
struct EditProfileView: View {
#State var birthDate : Date?
var dateFormatter: DateFormatter {
let formatter = DateFormatter()
formatter.dateStyle = .short
return formatter
}
var body: some View {
Form {
Section (header: Text("Birth day")) {
DatePicker(selection: Binding<Date>(get: { () -> Date in
self.birthDate ?? Date()
}, set: { (Date) in
self.birthDate = Date
}), in: ...Date(), displayedComponents: .date) {
Text("Select a date")
}
HStack {
Text( "You were born in :") + (birthDate == nil ? Text("") : Text("\(birthDate!, formatter: dateFormatter)"))
.font(.subheadline)
.foregroundColor(Color.gray)
Spacer()
Button(action: {
self.clearDate()
}) {
Text("Clear")
}
}
}
}
}
func clearDate () {
self.birthDate = nil
}
}
