Hide password with "•••••••" in a textField

in Swift 3.0 or Later

passwordTextField.isSecureTextEntry = true

You can achieve this directly in Xcode:

enter image description here

The very last checkbox, make sure secure is checked .

Or you can do it using code:

Identifies whether the text object should hide the text being entered.

Declaration

optional var secureTextEntry: Bool { get set }

Discussion

This property is set to false by default. Setting this property to true creates a password-style text object, which hides the text being entered.

example:

texfield.secureTextEntry = true
