Ionic 4 application navigation slow on device and emulator (ios)

Hello, I would like to know if someone has already been confronted with this problem, I have my application that normally works on android, but on ios, navigation is very slow . i use ionic 4

Hi @teslim2903 :wave:

Ionic 4 is pretty fast, even faster than Ionic 3 so it shouldn’t be the problem. I made several apps and they run crazy fast on older iPhones.

hello, the problem that I encounter on IOS is the navigation between the pages, the application crashes, and finally I see that the major cause is the plugin of the webview, uninstall this plugin and the application will use the default webview on your iPhone
