Swift: #warning equivalent

Question

Does Swift have a #warning equivalent? It\'s simply used to show a warning in Xcode\'s own GUI

I\'m also interested in whether there\'s a #error equivalent.

Answer 1

I may be late to the party with Xcode 10 supporting errors and warnings, but simply putting a String:

"Need to finish implementing this"

will produce a warning: String literal is unused with autocompletion still working and the project still compiling.
