Issue Description:

In swift 2.3, UI test generation creates the syntax (XCUIElement).children(matching: ) but the compiler only recognizes childrenMatchingType(), and you have to manually change the instances.

Example:

Generator creates:
app.collectionViews["LibraryStudioCollectionView"].cells["LibraryCreateAppletCell"].children(matching: .other).element.children(matching: .other).element.tap()

But has to be changed to this to run:
app.collectionViews["LibraryStudioCollectionView"].cells["LibraryCreateAppletCell"].childrenMatchingType(.Other).element.childrenMatchingType(.Other).element.tap()
