Need help to update IONIC app

I need to update my app because it uses UIWebView and it is now deprecated by Apple. Need to replace it by WKWebView in IONIC (probably change/update some plugins) in order to be able to upload a new version.

I can provide a Mac OS with Team Viewer in order to solve this.

PLEASE DON'T BID IF YOU HAVEN'T RESOLVED THIS PROBLEM BEFORE
Please contact me with keyword: IONIC first, I won't answer any other messages.
