Discussion

The completion handler in the synchronous version of this method receives true as its first parameter if the device is eligible to run a version of the app that contains an alternative browser engine; otherwise, it receives false. The second parameter that the completion handler receives is an error if any occurs; otherwise, it’s nil.

The async version of this method returns true if the device is eligible to run a version of the app that contains an alternative browser engine; otherwise, it returns false. The method throws an error if it encounters one.

To use the BEAvailability.Context.webBrowser context to test whether the device is eligible to use a web browser with an alternative browser engine, your app needs to have the com.apple.developer.web-browser entitlement. For information on adopting the web browser entitlement, see Preparing your app to be the default web browser.
