With visual format constraints?

Question

iOS

func setupMain(){
self.view.addSubview(selectDate)
self.view.addConstraint(NSLayoutConstraint.constraints(withVisualFormat: "H:|-16-[v0]-16-|", options: [], metrics: nil, views: ["v0":selectDate]))
}
What to specify in options?
Why does it keep giving an error. Error is something like you have an array but you do not need an array

Answer 1

translatesAutoresizingMaskIntoConstraints = false
