Answer 1

Yes, I have the problem too. there is a solution by Timur Bernikowich: https://github.com/bernikowich/NSTViewWarmuper

But, WKWebView is also slower than UIWebView with using loadHTMLString:baseURL: method.

Short but adequate solution: Disable phone number data detectors for you WKWebView (enabled by default if you use Storyboard).

Answer 3

Disabling WKWebView's data detectors worked for me. Swift version:

let webViewCofig = WKWebViewConfiguration()
webViewCofig.dataDetectorTypes = []
webView = WKWebView(frame: view.frame, configuration: webViewCofig)

To enable specific data detector, pass the specific type as .address,.link etc while setting dataDetectorTypes:

config.dataDetectorTypes = [.address]
