`@discardableResult override init()` in Swift 3.1 throwing `warn_unused_result` Objective-C warning

Question

I have a Swift class that is bridged to Objective-C. Even with @discardableResult, it's throwing this warning on build in the Objective-C class:

Ignoring return value of function declared with 'warn_unused_result' attribute

Is there a way to silence this? This is in Xcode 8.3 with Swift 3.1.

What is the point of the initializer if you're not using its result? — jscs, Mar 28 '17 at 17:38
@BenGuild Singletons should be initialized automatically and the initializer should not be accessible. This seems like a correct warning caused by poor API architecture. — Sulthan, Apr 18 '17 at 09:20

A cast to (void) should silence the warning:

(void)[SingletonClass sharedInstance];

Thanks. The warning seems to have disappeared on its own. – Ben Guild Apr 18 '17 at 13:28
