I was facing the same issue... You need to add the javaScriptCanOpenWindowsAutomatically = true to the WKPreference object in the WKWebview's Configuration... This will cause the createWebViewWith delegate to be called...
let wkPreferences = WKPreferences()
wkPreferences.javaScriptCanOpenWindowsAutomatically = true
Build the Configuration of the WKWebView object
let configuration = WKWebViewConfiguration()
configuration.preferences = wkPreferences
Naturally use the configuration object when creating the WKWebView
		webView = WKWebView(frame: .zero, configuration: configuration)

By far the easiest way is to locate the device in Finder ... then click on it to see the device info... Just drag the .ipa file anywhere in the device Info window, the drag icon will have a green plus... drop it and voila, the ipa is on your device.
