MacCatalyst tests crash on NSInternalInconsistencyException, reason: NSApplication has not been created yet It's unclear : - if the crashes are due to the inconsistent build (see bug 224605) - if it's somehow not constructing the UIApplication which would then probably construct the NSApplication - if it's just missing the runBlockWhenSharedDelegateBecomesAvailable 2021-04-15 05:41:14.144 TestWebKitAPI[95606:4911569] *** Assertion failure in -[UINSApplicationDelegate init], UINSApplicationDelegate.m:286 2021-04-15 05:41:14.167 TestWebKitAPI[95606:4911569] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSApplication has not been created yet.

Based on some discussion, this is likely due to: - TestWebKitAPI never was enabled for MacCatalyst (e.g. it's not implemented) - TestWebKitAPI is not a (UIKit?) "ui application"

*** Bug 224605 has been marked as a duplicate of this bug. ***
The *correct* fix for this is to make a proper UIApplication, but that is a bigger project. This gets us back to limping along like we used to, as the ChangeLog says. Enough so it is possible to write and run tests on macCatalyst.
