We are driving an initiative to measure compatibility between WebViews across the ecosystem. This repository is used to track tasks and the current state of the project.
I salute you for this effort, it won’t be trivial! For example, WKWebView doesn’t allow use of service workers… unless the domain you’re loading is included in the WKAppBoundDomains key of your app’s Info.plist file. Would be great to have all this info in one centralized place though!
