SwiftUI @State var initialization issue

Question

I would like to initialise the value of an @State var in SwiftUI trough the init() method of a Struct, so it can take the proper text

Answer 1

The answer of Bogdan Farca is right for this case but we can't say this is the solution for the asked question because I found there is the issue with the Textfield in the asked question. Still we can use the init for the same code So look into the below code it shows the exact solution for asked question.

struct StateFromOutside: View {
    let list = [
        "a": "Letter A",
        "b": "Letter B",
        // ...
    ]
    @State var fullText: String = ""

    init(letter: String) {
        self.fullText = list[letter]!
    }

    var body: some View {
        VStack {
            Text("\(self.fullText)")
            TextField("Enter some text", text: $fullText)
        }
    }
}

And use this by simply calling inside your view

struct ContentView: View {
    var body: some View {
        StateFromOutside(letter: "a")
    }
}
