Don't let Objective-C cramp your style 04 Jun 2016
A few days ago I was (finally!) updating a project to use Swift 2.2 and I ran into a few issues when converting to use the new
#selector syntax introduced by proposal SE-0022. If using
#selector from within a protocol extension, that protocol must be declared as
@objc. The former
Selector("method:") syntax did not have this requirement.
