My app currently supports 10.9, and I want to add a feature that
displays an HTML document stored locally (in the bundle). The obvious
way is to have a window which contains a web view. However, WKWebView is
only available in 10.10, and WebView is deprecated.
If it were a matter of calling a method, I could wrap it with
availability calls, but it's a definition of the class of an element in
a window controller class. Presumably there is a way to handle this, but
I haven't discovered it.
What I'm looking for is something like
if #available(macOS 10.10, *) {
var webView: WKWebView
}
else {
var webView: WebView
}
...but that is for running code, not declarations.
Is there a way to do this through IB? Or is my alternative to build the
window in code, using whatever is available based on the runtime platform?
