Which do you think the best way to pass data between the two sides of a split view? Which do you think the best way to call a method from master to detail or from detail to master? Protocols? Segues? Or...?
I have seen seem tutorials in this topic but I can not figure out what is the most trivial way of it.

Protocols are the best way if you need to use them for multiple UIViewControllers. Though if you need to explicitly communicate between two controllers, try simply storing a weak reference between them to call methods.
