Accidental use of the NSObject+FBKVOController.h in Swift?

[winzig]

The docs state:

For an even easier usage, just #import <KVOController/NSObject+FBKVOController.h> for an automatic KVOController property on all objects.

I am using Swift and I don't want that behavior, but it seems as though I am getting it now in Xcode 8.1 with Swift 3. I have installed KVOController 1.2.0 using CocoaPods. In a couple Swift files I have imported the library with:

import KVOController

To my knowledge I have not explicitly imported NSObject+FBKVOController.h, though I'm guessing it must be happening as part of the way this is getting utilized by Swift? Is there a way to prevent this?

[winzig]

The way I noticed this is after updating to Swift 3 and getting the latest Pods for my project, I began testing/compiling and was getting weird issues that my use of kvoController variables in a couple classes was trying to override an existing variable.

Hmm. We can improve this, but clashes are sort of in-evitable when it comes to using ObjC. kvoController or rather KVOController is quite a unique name, that we didn't think it was possible to clash on it.

We could introduce a sub-spec, meaning that you will be able to select which part you want explicitly.

In the meantime, the workaround for your case would be to simply copy/paste the FBKVOController.h/.m to your project instead of going via CocoaPods, hence the library is small enough.

OK, gotcha. It's not so much the collision I was worried about, but just assuming there is some (in my case unwanted) overhead from having the category in place on all my NSObjects.

Since it's lazy loaded, unless you explicitly invoke it - there should be no visible cost to having it.
