A Simple And Easy Text Field Control Written In Swift

I love Apple’s Swift programming language and how easy it is to create code in this language.

However, not all applications are created equal.

You probably don’t need an app that can do something like this:

Today, I’d like to present you a simple and easy text field control written in Swift, which is based on the concept of the Canvas TextField control.

If we have an interface that allows a user to enter text into a text field, we can use the control within our app.


A nice OTP textbox library for iOS, written in Swift with full accessibility user interface customization. AEOTPTextField is a simple and convenient text field control written in Swift.

  • It can be implemented in a storyboard without a single line of code.
  • x] Very customizable without having to write tons of custom code.
  • x] Support for portrait and landscape view.

Check out a sample project to see it in action!

Provisional sample



  • x] Xcode 11.
  • x] Swift 5.

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command: $ gem install cocoapods To include AEOTPTextField in your Xcode project with CocoaPods, specify it in your podfile: Source ‘’ Platform :ios, ‘10.0’ use_frameworks ! pod AEOTextField Then run the following command: $ pod install


The integration of AEOTPTextField with Carthage will be available soon.

Swift Package Manager

AEOTPTextField integration with the Swift package manager will be available soon.


Code-free implementation of storyboard

  1. Add a UITextField to your ViewController. Set the custom field class UITextField as AEOTPTextField in the Identity Inspector. Set the module to AEOTPTextField (skip this step if you added AEOTPTextField to your project manually).


  1. Bring the ultimate UITextField to your ViewController.



1 : import AEOTPTextField Set otpDelegate and configure AEOTPTextField under viewDidLoad(), do something like this: override func viewDidLoad() { super.viewDidLoad() otpTextField.otpDelegate = self otpTextField.configure() } To configure an AEOTPTextField with a user-defined number of slots, do approximately the following: override func viewDidLoad() { super.viewDidLoad() otpTextField.otpDelegate = self otpTextField.configure(with : 4) } Next configure the AEOTPTextFieldDelegate method. Add this extension to your ViewController, do something like this: ViewController extension: AEOTPTextFieldDelegate { func didUserFinishEnter(the code : String) { print(code) } } You have.


AEOTPTextField AEOTPTextField supports the following: // default character to be placed in text field locations public var otpDefaultCharacter = // default background color in text field locations before character entry public var otpBackgroundColor : UIColor = UIColor(red: 0.949, green: 0.949, blue: 0.949, alpha: 1) // Default background color for text field locations after character input public var otpFilledBackgroundColor: UIColor = UIColor(red: 0.949, green: 0.949, blue: 0.949, alpha: 1) // Corner radius of the standard text field slots public var otpCornerRaduis: CGFloat = 10 // default border color of text field locations before a character is entered public var otpDefaultBorderColor : UIColor = .clear // The border color of the text field slots after the character has been entered public var otpFilledBorderColor : UIColor = .darkGray // default border width of the text field slots before the character is entered public var otpDefaultBorderWidth : CGFloat = 0 // Text field border width after character input public var otpFilledBorderWidth : CGFloat = 1 // default text color public var otpTextColor : UIColor = .black // default font size public var otpFontSize : CGFloat = 14 // default font for text public var otpFont : UIFont = UIFont.systemFont(ofSize : 14) Example of adaptation override func viewDidLoad() { super.viewDidLoad() otpTextField.otpDelegate = self otpTextField.otpFontSize = 16 otpTextField.otpTextColor = .systemRed otpTextField.otpCornerRaduis = 5 otpTextField.otpFilledBorderColor = .blue otpTextField.configure(with : 4) } }


## GitHub we need to put a text field on a screen which has more than one line of text. For example, the image below shows a text field with three lines of text. The text field does not auto-size itself to the contents of the text field text, but needs to be manually sized and positioned..
