Into unit testing? If so you've probably found yourself in the dark alleys of Swift unit testing. If you haven't yet dabbled in unit testing, this talk will be an awesome opportunity to get started and charge up your unit testing superpowers. I explain three scenarios of unit testing with Swift, and provide us with practical advice for each of them and the implications of the recently introduced version 2 of Swift.

8. Before
Make everything public
or
Include the classes in
testing target
Detestable

9. After
@testable import Module
provides access to
everything internal
Testable

14. Before
Deal with pointers to
references and put the
data in there in order to
mock the behavior

15. After
Just implement a test for
the case when it fails and
mock the failure
