Swift 3 @objc interference issue not being fixed :-(

Before this gets marked as duplicate, I've already checked The use of Swift 3 @objc inference in Swift 4 mode is deprecated?

I'm resuming development on app which I had been working on before Xcode 9 (with Swift 4) was released.

I'm getting the build time 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 "Rushed" target."

I know how to turn on/off/default the build setting but even when I turn it on and then 'default' it, the warning is still appearing.

Scrolling through my files, there are no warnings/yellow triangles which could tell me where the issue is occurring and there's no 'Fix' button appearing.

Please help!

Are there other targets (a ...Tests target for example)? The warning is displayed for each target individually. – vadian
@vadian I'm not sure I understand :-( Where should I look? – Adi219
Select the project on the top of the project navigator and look at the targets. How many do you have? – vadian
@vadian Actually it's fine! I clicked on my project and then the Target section. It turns out that my app's @objc interference was on even though it was off in Project section. – Adi219

  1. Click on the project (the first thing in the massive drop-down list)
  2. Click on the Targets section that appears
  3. Search for the Swift 3 @objc interference section
  4. Turn it On and fix any warnings/errors that pop up
  5. Turn it to Default and your project should run without any issues
