After installing Xcode 9 and migrating to Swift 4 from Swift 3 I received this warning:
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 “AppName” target.
I resolved this issue by going to the projects build target. Selecting “Build Settings”. Searching for “Inference” then changing the setting for “Swift 3 @objc Inference” from “On” to “Default”. If you have multiple targets in your project you may have to do this for each target.
