now in swift 4 you just have to import a briding header into Test target and reference objc-class .h files there...using @testable import nameOfYourApp should work

In Swift there's a message in "Test Target" that states that the bridging header will be removed in newer versions of swift. I'm using mixed objc and swift clasess, but the UnitTest class is a swift file. Using @testable key was there in code

  @testable import YourProject

You fix it by adding in your Test area the bridging header with objc headers that your test will use:

iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)
