无法将“颜色”类型的值分配给“UIColor”类型

Question

When I set textField.textColor = Color.primary inside UITextViewWrapper class give this error.

How can I use primary color inside UITextViewWrapper? Is there any way to use it?

fileprivate struct UITextViewWrapper: UIViewRepresentable {
    typealias UIViewType = UITextView

    func makeUIView(context: UIViewRepresentableContext<UITextViewWrapper>) -> UITextView {
        let textField = UITextView()
        textField.textColor = Color.primary // here give error
        return textField
    }
          
 }

Answer 1

On iOS 14+ you can use the new UIColor initializer.

textField.textColor = UIColor(Color.primary)

For lower versions, you can use:

textField.textColor = UIColor.label // gives the same result

1. Extension UIColor:

    extension UIColor { class var primary: UIColor { return UIColor(named: "YourColorName")! } }

2. Usage:

    textField.textColor =.primary
