As wkWebView for the Mac does not supply scrollview and my app needs the scrollview property, I am forced to use webView which is deprecared . I'm currently thinking about how to avoid the absense of scrollview, but that is something for the future.
Does anyone know if the Mac App Store is currently rejecting apps using webView?
No. Legacy webviews are not a problem at this time. WkWebView still cannot even print on the Mac.
However, I would encourage you to resolve this problem sooner rather than later. Most anything you need can be implemented in HTML and JavaScript.
Soundls like you know what you are talking about. thanks
