let categoryField: UITextField = { let field = UITextField() field.layer.borderWidth = 0.5 field.layer.borderColor = UIColor.gray.withAlphaComponent(0.5).cgColor field.layer.cornerRadius = 5 field.textAlignment = .center field.selectedTextRange = nil field.placeholder = "Enter Title" field.heightAnchor.constraint(equalToConstant: 50).isActive = true field.translatesAutoresizingMaskIntoConstraints = false field.autocorrectionType = .no field.autocapitalizationType = .words return field }()Which is used below, inside of a viewDidLoad method in a viewController.let stackView = UIStackView(arrangedSubviews: [ categoryField, UIView() ]) stackView.isUserInteractionEnabled = true stackView.axis = .vertical stackView.alignment = .fill stackView.spacing = 8It works on Simulator, but when I take the code to a device it doesn't work at all. I've used the same code in other apps and they worked fine. Any thoughts on why it won't work in this?

Are we not supposed to be able to make custom Picker Styles? struct CustomPickerStyle: PickerStyle { static func _makeView<SelectionValue>(value: _GraphValue<_PickerValue<CustomPickerStyle, SelectionValue>>, inputs: _ViewInputs) -> _ViewOutputs where SelectionValue : Hashable { } static func _makeViewList<SelectionValue>(value: _GraphValue<_PickerValue<CustomPickerStyle, SelectionValue>>, inputs: _ViewListInputs) -> _ViewListOutputs where SelectionValue : Hashable { } }
