Presenting an alert - xcode

Question

I running SwiftUI with Xcode 11 Beat 5, and I wish to add an Alert to show the user when a Button is Tapped.
I am having problems though.
HStack{
Text("Inverted V")
.font(.largeTitle)
.fontWeight(.bold)
.foregroundColor(Color.black)
Spacer()
Button(action: {
}, label: {
Image(systemName: "questionmark.circle.fill")
.resizable()
.frame(width: 30, height: 30)
.foregroundColor(.red)
}).onTapGesture {
print("Hello Print")
}}
Can someone help with the code needed? Do I place it within the onTapGesture brackets?
I have a #State var showingAlert = false
Thank you in advance.

Answer 1

You would use something like the code below. If you are using onTapGesture you don't need a Button.
import SwiftUI
struct ContentView: View {
#State var showingAlert: Bool = false
var body: some View {
HStack{
Text("Inverted V")
.font(.largeTitle)
.fontWeight(.bold)
.foregroundColor(Color.black)
Spacer()
Image(systemName: "questionmark.circle.fill")
.resizable()
.frame(width: 30, height: 30)
.foregroundColor(.red)
.onTapGesture {
print("Hello Print")
self.showingAlert = true
}
}.alert(isPresented: $showingAlert, content: {
Alert(title: Text("Error"), message: Text("Error Reason"), dismissButton: .default(Text("OK")))
})
}
}
