Hello! my setup: Construct 2 - 241 beta, Intel XDK 3759 Corodva CLI any 6.2 or 5.4, export to ios 9 with WKWebView
Result is like full without WKWebView - very slow all motions and loadings in my project
Here is the same question with a detailed description: https://www.scirra.com/forum/very-low-performance-with-wkwebview_t185638
Steps to reproduce issue:
1. Export from Construct 2 with WKWebView option enabled
2. Build project in Intel XDK with added in "Plugin Management" WKWebView, File and Httpd
3. Run on the iPhone 6 with ios 9
Maxim -- sorry, but we are not experts on Construct2 apps, nor are we experts on the idiosyncracies of the various iOS webviews, so we do not have any quick answers for you.
I recommend that you take a look at the debugging and testing pages in the documentation > https://software.intel.com/en-us/xdk/docs/lp-debugging < for guidance regarding the various debug options that are available to you. Given that the vast majority of people have no performance issues with WkWebView I would guess that there is something in the app that is causing the problem, and you'll need to isolate that "something" through some debugging in order to then understand how to fix the issue.
