Usage

Code-less Storyboard Implementation

Add UITextField to your ViewController. Set the Custom Class of the UITextField to be AEOTPTextField in the Identity Inspector. Set the Module to AEOTPTextField (ignore this step if you've manually added AEOTPTextField to your project).
Take an oultlet from the UITextField to your ViewController.

UIKit Code Implementation

First:

import AEOTPTextField

Setup the otpDelegate and configure the AEOTPTextField below viewDidLoad(), do something like this:

    override func viewDidLoad() {
        super.viewDidLoad()
        otpTextField.otpDelegate = self
        otpTextField.configure()
    }

To configure the AEOTPTextField with a custom slots count, do something like this:

    override func viewDidLoad() {
        super.viewDidLoad()
        otpTextField.otpDelegate = self
        otpTextField.configure(with: 4)
    }

Then, Setup the AEOTPTextFieldDelegate method. Add this extension to your ViewController, do something like this:

extension ViewController: AEOTPTextFieldDelegate {
    func didUserFinishEnter(the code: String) {
        print(code)
    }
}

You have done.

SwiftUI Code Implementation

First:

import AEOTPTextField

Then, use tha AEOTPView in your SwiftUI View, do something like this:

struct SwiftUIView: View { 
    @State private var otp: String = ""
    
    var body: some View {
        AEOTPView(text: $otp)
    }
}

You have done.

UIKit Customization

AEOTPTextField AEOTPTextField supports the following:

    /// The default character placed in the text field slots
    public var otpDefaultCharacter = ""
    /// The default background color of the text field slots before entering a character
    public var otpBackgroundColor: UIColor = UIColor(red: 0.949, green: 0.949, blue: 0.949, alpha: 1)
    /// The default background color of the text field slots after entering a character
    public var otpFilledBackgroundColor: UIColor = UIColor(red: 0.949, green: 0.949, blue: 0.949, alpha: 1)
    /// The default corner raduis of the text field slots
    public var otpCornerRaduis: CGFloat = 10
    /// The default border color of the text field slots before entering a character
    public var otpDefaultBorderColor: UIColor = .clear
    /// The border color of the text field slots after entering a character
    public var otpFilledBorderColor: UIColor = .darkGray
    /// The default border width of the text field slots before entering a character
    public var otpDefaultBorderWidth: CGFloat = 0
    /// The border width of the text field slots after entering a character
    public var otpFilledBorderWidth: CGFloat = 1
    /// The default text color of the text
    public var otpTextColor: UIColor = .black
    /// The default font size of the text
    public var otpFontSize: CGFloat = 14
    /// The default font of the text
    public var otpFont: UIFont = UIFont.systemFont(ofSize: 14)

Aslo you can use isSecureTextEntry property:

    otpTextField.isSecureTextEntry = true

Example of Customization

    override func viewDidLoad() {
        super.viewDidLoad()
        otpTextField.otpDelegate = self
        otpTextField.otpFontSize = 16
        otpTextField.otpTextColor = .systemRed
        otpTextField.otpCornerRaduis = 5
        otpTextField.otpFilledBorderColor = .blue
        otpTextField.configure(with: 4)
    }
}
