[swift] Hide password with "•••••••" in a textField

In my app there is a textField where the user have to put is password in and i want that when he enter a character it change it to '•' how can i do this?

You can do this by using properties of textfield from Attribute inspector

Tap on Your Textfield from storyboard and go to Attribute inspector , and just check the checkbox of "Secure Text Entry" SS is added for graphical overview to achieve same

In XCode 6.3.1, if you use a NSTextField you will not see the checkbox for secure.

Instead of using NSTextField use NSSecureTextField

https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSSecureTextField_Class/index.html

I'm guessing this is a Swift/Objective-C change since there is now a class for secure text fields. In the above link it says Available in OS X v10.0 and later. If you know more about when/why/what versions of Swift/Objective-C, XCode, or OS X this

in Swift 3.0 or Later

passwordTextField.isSecureTextEntry = true

Programmatically (Swift 4 & 5)

self.passwordTextField.isSecureTextEntry = true

For SwiftUI, try

TextField ("Email", text: $email)
    .textFieldStyle(RoundedBorderTextFieldStyle()).padding()
SecureField ("Password", text: $password)
    .textFieldStyle(RoundedBorderTextFieldStyle()).padding()

Swift 4 and Xcode Version 9+

Can be set via "Secure Text Entry" via Interface Builder
