Cuckoo: Error: Expected member name or constructor call after type name

Xcode 15

GeneratedMocks.swift is showing errors for:

return DefaultValueRegistry.defaultValue(for: (Observable<T>).self)

\\ Expected member name or constructor call after type name
\\ Use '.self' to reference the type object <Fix>

If I edit it to:

return DefaultValueRegistry.defaultValue(for: Observable.self)

the error goes away.

If I fix the errors in the generated file and skip the Cuckoo script phase, I am able to compile and run unit tests in both Xcode 15 and Xcode 14.3.1

@chirag05k If your case is like mine, you don’t need to use a special branch of Cuckoo. Try renaming Observable to RxSwift.Observable in the class you’re mocking out (e.g. rename your startSession method’s return type).

Swift 5.9 added a new Observable type that now shadows RxSwift’s Observable.

@TadeasKriz That was it! Tricky, because when I use Xcode to click into the Observable it would take me to RxSwift’s type.

After updating my protocols to use RxSwift.Observable over Observable, my remaining project errors have been resolved.

Is this Xcode 15? I think Observable is now a macro for SwiftUI, so maybe try RxSwift.Observable<IBluetoothPeripheral>, that might work.
