How to add Dots instead of showing number ?

You can't. Well, at least not without editing the source code. I.e., there's no property you can set, like the secureTextEntry property of UITextInputTraits. Although, that would be a cool option and should be fairly easy to add. See if you can figure it out. ;-)

how to set "secureTextEntry" in swift can u help me in that. i tried below code and "var secureTextEntry: Bool { get{ return true} set {} }" and got an error

[ma11hew28]

Hmm... Try asking on Stack Overflow.

Here's the basic idea.

• On line 43, change the last word text to a dot "•"
• Add a String property called code to store the code
• Update code accordingly in deleteBackward & insertText:

Bonus

• Add a Bool property called secureTextEntry
• If true, use dots; else, use text

Note: Don't make CodeInputView conform to UITextInputTraits.

        }

        nextTag += 1

        if nextTag == 5 {

            delegate?.codeInputView(self, didFinishWithCode: secureCode)

        }
    }
}

func deleteBackward() {
    if nextTag > 1 {
        nextTag -= 1
        (self.viewWithTag(nextTag) as! UILabel).text = " "

        secureCode = String(secureCode.characters.dropLast())
    }
}

func clear() {
    while nextTag > 1 {
        deleteBackward()
    }
}

// MARK: - UITextInputTraits

var keyboardType: UIKeyboardType { get { return .NumberPad } set { } }

}

protocol CodeInputViewDelegate {
func codeInputView(codeInputView: CodeInputView, didFinishWithCode code: String)
}

Use it as codeInputView?.secure = true will display your text securely as dot i.e. \u{2022}

That works !!! Thanks @chandanvarma009
