Xcode 13 Introduces a New Way for Handling Expected Unit Test Failures

In my previous blog post [https://jayeshkawli.ghost.io/handling-expected-unit-test-failures-on-swift/], I wrote about using a couple of ways to either suppress or skip expected test failures. In Xcode 12.5, Apple introduced a new API XCTExpectFailure [https://developer.apple.com/documentation/xctest/3726077-xctexpectfailure] to provide a better way to handle
