[EarlGrey1] "Failed to load the test bundle" error in Xcode 14

[adil-hussain-84]

Running EarlGrey1 tests against the iOS 13 Simulator is possible in Xcode 13 and older versions but not in Xcode 14.0, Xcode 14.1 and possibly newer versions of Xcode 14.

Running EarlGrey1 tests in Xcode 14.0 and Xcode 14.1 results in the following error:

  Assertions: System: Failed to load the test bundle. If you believe this error represents a bug, please attach the result bundle at /Users/adilhussain/Library/Developer/Xcode/DerivedData/EarlGreyExperiment-dxfuddrtpdijnhhhmgkzxzvtmhad/Logs/Test/Test-EarlGreyExperiment-2022.11.01_08-37-29-+0000.xcresult.

  Reason: Incompatible library version: EarlGrey requires version 1.0.0 or later, but XCTest provides version 0.0.0)

You can see this error firsthand in this super simple Xcode workspace. The tests in this workspace run fine in Xcode 13 but not in Xcode 14.

Note: I am aware that EarlGrey1 is deprecated. I am sharing this as a point of information for anyone like me who still has EarlGrey1 tests that they have not yet migrated away from EarlGrey1.
