How to present an Alert with swiftUI

.presentation() was actually deprecated in Beta 4. Here is a version that currently works with the .alert() Modifier.

struct ContentView: View {    @State var showsAlert = false    var body: some View {        Button(action: {            self.showsAlert.toggle()        }) {            Text("Show Alert")        }        .alert(isPresented: self.$showsAlert) {            Alert(title: Text("Hello"))        }    }}

You can use a @State variable as the binding. Alternatively you can use a @EnvironmentObject variable that uses a BindableObject.

I think you need to call presentation on the root View to get it to work, adding it to a Stack, Group, etc. doesn't seem to work.

This snippet seems to do the trick. Note that @State variable is set to false after the alert is dismissed.

struct ContentView: View {    @State var showsAlert = false    var body: some View {        Button(action: {            self.showsAlert = true        }, label: {            Text("asdf")        }).presentation($showsAlert, alert: {            Alert(title: Text("Hello"))        })    }}

Full Code of Alert with dismiss and okay action:

Code:

import SwiftUIstruct ContentView: View {    @State private var isAlert = false    var body: some View {            Button(action: {                self.isAlert = true            }) {                Text("Click Alert")                .foregroundColor(Color.white)            }            .padding()            .background(Color.blue)            .alert(isPresented: $isAlert) { () -> Alert in                Alert(title: Text("iOSDevCenters"), message: Text("This Tutorial for SwiftUI Alert."), primaryButton: .default(Text("Okay"), action: {                    print("Okay Click")                }), secondaryButton: .default(Text("Dismiss")))        }    }}struct ContentView_Previews: PreviewProvider {    static var previews: some View {        ContentView()    }}
