You also need to set border width, because your border color is set already but your default border width is 0.0 so you can't see it.
您还需要设置border width，因为您的边框颜色已经设置，但您的默认边框宽度为 0.0，因此您看不到它。
So, set border width something like,
所以，设置边框宽度类似，
email.layer.borderWidth = 1.0

I think you should first provide a borderWidth
我认为你应该首先提供一个 borderWidth
@IBOutlet weak var email: UITextField!
@IBOutlet weak var pass: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
let myColor : UIColor = UIColor.white()
email.layer.borderWidth = 1
email.layer.borderColor = myColor.cgColor
pass.layer.borderColor = myColor.cgColor
}
and then set a color :)
然后设置颜色:)

bottomLine.backgroundColor = UIColor.gray.cgColor // background color
yourTextFieldName.borderStyle = UITextBorderStyle.none // border style
yourTextFieldName.layer.addSublayer(bottomLine)

You need to set the borderWidthfrom the UITextField's layerproperty.
您需要设置borderWidthfromUITextField的layer属性。
Like: email.layer.borderWidth = 1.
喜欢：email.layer.borderWidth = 1。
Also, if you frequently need to set borders to your views, you can make an extension like this:
此外，如果您经常需要为视图设置边框，您可以进行如下扩展：
extension UIView {
func addBorderAndColor(color: UIColor, width: CGFloat, corner_radius: CGFloat = 0, clipsToBounds: Bool = false) {
self.layer.borderWidth = width
self.layer.borderColor = color.cgColor
self.layer.cornerRadius = corner_radius
self.clipsToBounds = clipsToBounds
}
}
Call this like:
email.addBorderAndColor(color: UIColor.white, width: 0.5, corner_radius: 5, clipsToBounds: true)
像这样调用：
email.addBorderAndColor(color: UIColor.white, width: 0.5, corner_radius: 5, clipsToBounds: true)
Since this method sets the borderWidth, it will also solve your problem.
由于此方法设置borderWidth，它也将解决您的问题。
