[Please only bid if you have relevant experience and understanding of WkWebview. You MUST have a mac and a jailbroken iphone to qualify for this. To begin, tell me your iphone model and os version for checking]
Given that my iphone is jailbroken, from a third party app which has built-in webview( like tiktok, facebook) everytime the app open a webpage in its built-in browser(hence the webview), I want to inject a javascript code into the webview once the document finished loading. Manually we could achieve this by using safari webinspector together with the global tweak at https://github.com/ChiChou/GlobalWebInspect, now I need it to be done automatically for every web page loaded. The script can be fixed and hard coded (like document.body.style.backgroundColor = 'red' ). You may think of override wkwebview delegate method at app level, or modify the whole system for any app with built-in browser, making a tweak or a frida script to inject in, any method is fine.

Tell me any of your experience with iOs tweak making, iOs frida script or WkWebview customization
