WKWebView constrains issue when keyboard pops up

Question

When an input in WKWebView gets focused a constraints error pops up.

Code:

class ViewController: UIViewController {
          


        

Answer 1

One or more constraints are not compatible at the same time when keyboard is open.

Instead of doing frame by hand, try setting constraints to ur WKWebView.

private func addWKWebView(){
    let wv = WKWebView()
    view.addSubview(wv);
    wv.translatesAutoresizingMaskIntoConstraints = false


    wv.widthAnchor.constraint(equalTo:   view.widthAnchor  ).isActive = true
    wv.heightAnchor.constraint(equalTo:  view.heightAnchor ).isActive = true
    wv.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    wv.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
}

or Something like this:

private func addWKWebView(){
    let wv = WKWebView()
    view.addSubview(wv);
    wv.translatesAutoresizingMaskIntoConstraints = false


    wv.widthAnchor.constraint(equalToConstant:  100).isActive = true
    wv.heightAnchor.constraint(equalToConstant: 100).isActive = true
    wv.widthAnchor.constraint(equalToConstant:  100).isActive = true
    wv.heightAnchor.constraint(equalToConstant: 100).isActive = true
}

U need to play around with your constraints to set the WkWebView where u want.
