Yes and no.  The problem with all these exercises is that they 
say nothing about the language and a lot about some default 
library, which isn't particularly revealing.

For instance, Swift drags in all of Os-X on the default platform, 
so writing an audio/video loader would be relatively short in 
comparison to other languages. Would that be fair or instructive? 
Of course not. The Os-X libraries are quite massive.

Anyway, these kinds of exercises are only impressive for people 
looking for an alternative to scripting...

For general system programming you need to show off the language 
and not the esoteric features of the standard library. Basically 
show off how it can deal with a task it has not been designed 
for. Which is the typical use scenario.
