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
`

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() }posix88 commentedon Jun 5, 2018
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.
