初期化方法

struct SearchView: View {
    @Binding private var searchText: String

    init(searchText: Binding<String>) {
        self._searchText = searchText
    }

    var body: some View {
        Text(searchText)
    }
}

ポイント1
init(searchText: Binding<String>)
Binding<型名>で定義する

ポイント2
_searchText
変数名の前に_を付けることでBindingを示す
