implement FasterVerificationCode programatically

[d33pak-s1ngh]

Hello @posix88 i am new to swift and ios. I want to implement this otp text field in my verfication view controller programatically. Do you have any example for this it will be help ful.

Following code i have tried
`

lazy var newVerification: VerificationCodeView = {
        let vv = VerificationCodeView()
        vv.translatesAutoresizingMaskIntoConstraints = false

    vv.setLabelNumber(6)
    vv.delegate = self
    vv.labelHasBorder = true
    vv.borderHeigth = 1
    vv.labelBorderColor = UIColor.black
    vv.labelErrorColor = UIColor.red
    vv.labelTextColor = UIColor.black
    //vv.labelBackgroundColor =
    vv.labelWidth = 24
    vv.isNumeric = true
    vv.labelSpacing = 16
    
    
    return vv
}()

func setupCode(){
    
    view.addSubview(newVerification)
    newVerification.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
    newVerification.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
    if #available(iOS 11.0, *) {
        newVerification.topAnchor.constraint(equalTo: view.topAnchor,constant: 50).isActive = true
    } else {
        // Fallback on earlier versions
    }
    newVerification.heightAnchor.constraint(equalToConstant: 80).isActive = true
    
}`

what this lines means "declare it as placeholder (the view will resize at runtime following labels dimensions)." because i am getting error of label size which says found nil while unwrapping optionals.

getting error in following function

public func setLabelNumber(_ numberOfLabel: Int) { guard numberOfLabel > 0 else { return } labelContainer.spacing = labelSpacing > 0 ? labelSpacing : 10 self.numberOfLabel = numberOfLabel calculateViewWidth() addLabelsToStackView() }

hi @d33pak-s1ngh,

about this issue:
#1 (comment)

you have to declare the width constraint as placeholder, you can do easily selecting you constraint and opening the size inspector tab on the right.

I'm sorry but right now the library is designed to be loaded from a xib and not programatically.
