The issue with this is about converting a UIColor to a CGColor, which is explained in the above answers, but put most simply, all you have to do to do this conversion is add .CGColorto the end of your UIColor. i.e.
这个问题是关于将 UIColor 转换为 CGColor，这在上面的答案中进行了解释，但最简单地说，进行此转换所需要做的就是添加.CGColor到 UIColor 的末尾。IE
myTextField.layer.borderColor = UIColor( red: CGFloat, green: CGFloat, blue:CGFLoat, alpha: CGFloat ).CGColor

What I do in swift and what ALWAYS works:

You might also want to add line like:
您可能还想添加如下行：
myTextField.layer.borderWidth = CGFloat(1.0)
To previous answers.
对于以前的答案。
In my case, color change wasn't visible, until I placed this line.
就我而言，颜色变化是不可见的，直到我放置了这条线。

Try this,
尝试这个，
extension UITextField{
func setBorderColor(width:CGFloat,color:UIColor) -> Void{
self.layer.borderColor = color.cgColor
self.layer.borderWidth = width
}
}
and implement this function wherever you want,
并在任何你想要的地方实现这个功能，
textField.setBorderColor(width: 2.0, color: UIColor.brown)
Hope this help!
希望这有帮助！
