[EarlGrey2] Host background port not assigned. Application under test may have failed to launch with latest Cocoapods

[badrinrs]

When point the cocoapods to latest earlgrey2 branch, I am seeing an issue with a header (GREYDescribeVariable.h) not being accessible in GREYAssertionDefinesPrivate.h file.
Once I made GREYAssertionDefinesPrivate.h public in Target membership section, The app and test compiled fine and were installed and launched.

After launching, I saw an error: 2023-01-23 10:07:29.305585-0800 [62174:24241479] [EARLGREY-LOG] Application Launch Completed.

@badrinrs I'm not sure if you managed to figure this out but this error usually happens if you're trying to use an EG function before your XCUIApplication has actually finished booting up.
