I see why you reiterated the word 'view'. 
Please remove the duplicate. It looks better if you do so.

New files should follow showcase convention where "sc_" is prepended.

[edchin, 2017/07/07 05:00:49]

I agree with gchatz. But, I can see why you didn't follow the convention.
The only view controller in the example list does not use the prepend, while 
all coordinators do. I think it makes sense to use the convention.

Done.
