SwiftUI - Why can't I use an Alert within an if statement - if-statement

Question

I'm currently working through the #100daysofswiftUI and have a quick question regarding the use of alerts within if statements. This particular task is at the end of the second project.
Here is the code:
.alert(isPresented: $showingScore) {
if x == 1 {
Alert(title: Text(scoreTitle), message: Text("The correct answer was \(countries[correctAnswer])"), dismissButton: .default(Text("Restart")) {
self.askQuestion()
})
}
}
I feel like this code should work however I have a yellow alert over the Alert line saying:
Result of 'Alert' initializer is unused
I don't know what this means, how can I fix this?

Answer 1

You need to return an Alert in the .alert modifier, not an if statement.
For this you can create a computed property which returns an Alert:
var alert: Alert {
if x == 1 {
return Alert(
title: Text(scoreTitle),
message: Text("The correct answer was \(countries[correctAnswer])"),
dismissButton: .default(Text("Restart")) {
self.askQuestion()
}
)
} else {
return Alert(...) // return some other `Alert`
}
}
and use it in the .alert modifier:
.alert(isPresented: $showingScore) {
alert
}
Just make sure you only enable showingScore when you want to show an alert.

Answer 2

you should put your if condition with showingScore,
do something like this
if x == 1 {
showingScore = true
}
your alert will look like this
.alert(isPresented: $showingScore) {
Alert(title: Text(scoreTitle), message: Text("The correct answer was \(countries[correctAnswer])"), dismissButton: .default(Text("Restart")) {
self.askQuestion()
})
}
