IBActions reported as unused

[Servus7]

All IBActions In our project are incorrectly marked as not used. IBInspectable and IBOutlet however are marked only if unused.
What could be the difference resulting in all IBActions being false positives?

Servus 👋

That certainly shouldn't be happening. We've already test coverage for IBAction: https://github.com/peripheryapp/periphery/blob/master/Tests/XcodeTests/iOSProject/iOSProject/XibViewController.swift#L4-L7 So there must be something a little different about your usage.

Could you take a look again and see if there's any special about the way you're using IBAction perhaps? If not, please provide an example.

I see the same issue if my @IBAction is private. Same happens for @objc, gets marked as unused as soon as it is private.

In my project, I don't have false positives for my private @IBAction.

I see the same issue if my @IBAction is private.

I'm also unable to reproduce this by making them private.

Same happens for @objc, gets marked as unused as soon as it is private. Are you talking about methods in general, or only @IBAction methods?

Are you using the new --retain-objc-accessible option? If so, I believe I've identified a bug with that: #238

[Servus7]

I added --retain-objc-accessible and the false positives are gone. Thank You! I'll start removing unused code.
EDIT: Private IBActions are still reported unused

@Servus7 That option is only intended for use with mixed Swift/Objc projects. It shouldn't be used just to fix IBAction false positives. If a class is referenced by a nib, then it's IBActions should also be identified as used.

Do you have any instances of IBAction being reported as unused in a class that also has IBOutlet/Inspectable that aren't being reported as unused? If so, please provide as much code as possible from this class so that I may diagnose.

We were using Resources Bundles and doesn't added them to periphery scan 🤦🏻‍♂️
