The following will not work and will throw the error "Initializer 'init(_:rowContent:)' requires that 'String' conform to 'Identifiable'"
import SwiftUI
struct ContentView: View {
@State var array:[String] = ["a", "b", "c", "d"]
var body: some View {
List(array) { item in
Text(item)
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}Here is how to fix that. Simply add the following 3 lines of code:
extension String: Identifiable {
public var id: String { self }
}Here is the final product:
import SwiftUI
struct ContentView: View {
@State var array:[String] = ["a", "b", "c", "d"]
var body: some View {
List(array) { item in
Text(item)
}
}
}
extension String: Identifiable {
public var id: String { self }
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
