Swift单元测试无法识别新的类初始化程序

Question

I changed the initializer signature on a Swift class. My other swift classes recognized the change, but my unit test class is giving me an error when I update the method call

Extra argument 'bundle' in call

Here is my new initializer signature:

var vc = ListController(nibName: nil, bundle: nil, contractor: theContractor)

The old one was:

var vc = ListController(nibName: nil, bundle: nil, contractor: theContractor, estimate: theEstimate)

Things I have tried:

1. Cleaned project
2. Removed and re-added the ListController and the test class from compile sources for both the unit test target and the test target
3. Removed project's derived data
4. Have completely re-written the test class from scratch just to put it under a new file name

The bottom line as of right now is that my test class is not recognizing the initializer signature change.

ListController is written in Swift as well as the test class.

Even the autocomplete puts in the correct method signature. But if you do CMD+Space on the method signature it says "Symbol Not Found".

From Sergiy Salyuk here :

Swift makes inherited initializers inaccessible for clients of your derived class when you add a designated initializer. It looks similar to private inheritance in C++ where the inherited methods/data are implicitly moved to the "private" class section. The reason is simple: if there is a custom initializer then your class probably requires this initializer to construct class "invariant". But there is a bug: if you create class derived from UITableViewController and add custom initializer that calls super.init(style:) it will fail with use of unimplemented initializer 'init(nibName:bundle:)'

Sounds like you've encountered essentially the same issue?
