As already mentioned in other answers, there is no way to avoid the @objc annotation for selectors.

But warning mentioned in the OP can be silenced by taking following steps:

1. Go to Build Settings
2. Search for keyword @objc
3. Set the value of Swift 3 @objc interface to Off

below is the screenshot that illustrates the above mentioned steps:

Hope this helps
