To display a dialog in SwiftUI, you can use the alert or sheet modifiers, depending on the type of dialog you want to present. Here are some examples:
Using alert
The alert modifier is used to present an alert dialog with a title, message, and buttons.
struct ContentView: View {
@State private var showAlert = false
var body: some View {
Button("Show Alert") {
showAlert = true
}
.alert("Alert Title", isPresented: $showAlert) {
Button("OK", role: .cancel) { }
} message: {
Text("This is an alert message.")
}
}
}
Using sheet
The sheet modifier is used to present a modal view.
struct ContentView: View {
@State private var showSheet = false
var body: some View {
Button("Show Sheet") {
showSheet = true
}
.sheet(isPresented: $showSheet) {
SheetView()
}
}
}
struct SheetView: View {
var body: some View {
Text("This is a sheet.")
}
}
Using confirmationDialog
For more complex dialogs, you can use confirmationDialog.
struct ContentView: View {
@State private var showDialog = false
var body: some View {
Button("Show Dialog") {
showDialog = true
}
.confirmationDialog("Dialog Title", isPresented: $showDialog) {
Button("Option 1") { }
Button("Option 2") { }
Button("Cancel", role: .cancel) { }
} message: {
Text("This is a confirmation dialog.")
}
}
}
