ios - Is WKWebView designed as a replacement of UIWebView?

Question

Asking this questions as I am not sure why Apple introduced WKWebView without deprecating UIWebView. It is important to have an idea as I am programming a large code base and need to make an informed / fact based decision.

• Are there any reason for which we may have to expect both classes to co-exist in the future and none get deprecated?

• Is WKWebView purely designed for speed performance (using JIT) and will likely to serve only for certain use cases?

Current limitations of WKWebView:

How can I retrieve a file using WKWebView?

Answer 1

According to Xcode 9, UIWebView is deprecated. ???♂?

And a documentation message reads:

Legacy UIWebView for support of older macOS platforms. Prefer using WKWebView if possible.

Updated: UIWebView is deprecated for real now in iOS 12. https://developer.apple.com/documentation/uikit/uiwebview
