B4i (iOS) v6.50

• Internal WebView is now based on WKWebView. There is also a new EvaluateJavaScript method.
• Launch images were removed and replaced with a launch story board. In most cases you can keep the default white one as apps start very quickly anyway.
  With this change the apps will run with the full resolution on all devices.
• HttpJob.ErrorMessage returns the server response when there are errors and the response is still available.
• IDE shows messages about available updates.
• All the IDE windows preserve their layout.
• Search results font can be changed in the font picker dialog.
• Support for Swift frameworks with Xcode 11.
• Other minor IDE improvements.

Note that there might be subtle behavior differences between UIWebView and WKWebView. Apple will soon reject apps based on UIWebView so the change is mandatory.
