Requires that 'FormFields' conform to 'FocusStateCompliant'

[denis-obukhov]

What's wrong with this code?

enum FormFields {
	case firstName, lastName, email, password
}

struct SignUpView: View {
	@FocusStateLegacy var focusedField: FormFields?
	@State var firstName = ""

	var body: some View {
			TextField(
				"First name",
				text: $firstName
			)
			.focusedLegacy($focusedField, equals: .firstName)
	}
}

The issue is "Instance method 'focusedLegacy(_:equals:)' requires that 'FormFields' conform to 'FocusStateCompliant'"

Sorry, I forgot about the extension:

extension FormFields: FocusStateCompliant {
	static var last: FormFields {
		.firstName
	}

	var next: FormFields? {
		switch self {
		case .firstName:
			return .lastName
		case .lastName:
			return .email
		case .email:
			return .password
		default: return nil
		}
	}
}
