I changed the "Swift 3 @objc Inference" build setting to "Default" in reference to Migrate to Swift 4 @objc inference , but this warning has remained.

The use of Swift 3 @objc inference in Swift 4 mode is deprecated. Please address deprecated @objc inference warnings, test your code with “Use of deprecated Swift 3 @objc inference” logging enabled, and then disable inference by changing the "Swift 3 @objc Inference" build setting to "Default" for the "SYBlinkAnimationKit" target.

I couldn't solve the issue, so I think should tackle as other issue.
