Mock CLBeacon Object in Swift

I have been searching online for a way to mock a CLBeacon object in order to test one of my classes. All I can find is related to COMockito which is only compatible with Objective-c.

All I need, is to be able to create a mock CLBeacon and set its major minor and UUID values. The problem is that these parameters are read only.

Any idea on what I could do to have a mock CLBeacon with parameters that I set?
