ios – Conflicting arguments to generic parameter ‘Content material’

Hi all I am utilizing an array of Enums to create a TextField with a floating label.

Once I go to run my code it offers me an error proper on ForEach(ExamFocusedField.allCases) { subject in }

Conflicting arguments to generic parameter 'Content material' ('<<gap>>' vs. '<<gap>>' vs. '<<gap>>' vs. '<<gap>>')

The place am I doing unsuitable?

enum ExField: Hashable, CaseIterable, Identifiable {
    
    case title, trainer, classRoom
        
    // conforme al protocollo "Identifiable"
    var id: Int {
        change self {
        case .title: return 0
        case .trainer: return 1
        case .classRoom: return 2
        }
    }
    
    var icon: String {
        change self {
        case .title: return "doc.plaintext.fill"
        case .trainer: return "graduationcap.fill"
        case .classRoom: return "door.sliding.proper.hand.open"
        }
    }
    var titleKey: String {
        change self {
        case .title: return "ex1"
        case .trainer: return "ex2"
        case .classRoom: return "ex3"
        }
    }
