How to import SKTUtils in Objective-C?

Question

I'm trying to import SKTUtils - which is a set of swift files - into an Objective-C project. As far as I know it would be enough to do this way:

#import "ProjectName-Swift.h"

But the problem is that SKTUtils is not a project, but rather a directory with a set of swift classes. I tried to import the files this way:

#import "Vector3-Swift.h"
#import "CGFloat+Extensions-Swift.h"
.... etcetera ....

But without success. I've also set to yes the define modules option inside the project's build setting but still nothing to do.

I have just tried to import SKTUtils in blank Objective-C Xcode project.

Looks like you are missing the following part of requirement for correct bridging:

You need to import ProjectName-Swift.h. Note that it's the project name - the other answers make the mistake of using the class name.

This single file is an autogenerated header that defines Objective-C interfaces for all Swift classes in your project that are either annotated @objc or inherit from NSObject.

taken from How to import Swift code to Objective-C.

For example in my test project my Project-Swift.h does contain imports of SKTUtils's extensions of SKAction because they are Objective-C-based classes of SpriteKit but some other stuff is not Objective-C friendly that's why you cannot access it because it is just not generated in -Swift.h file.

Another example is that I start seeing SKTAudio class in my Objective-C code if I make it a subclass of NSObject:

 @objc public class SKTAudio: NSObject {

But it's not a project, it's just a set of swift files. – Ramy Al Zuhouri Apr 05 '16 at 22:24
In `#import "ProjectName-Swift.h"` `ProjectName` is your main project, it is not! the name of Swift project you want to import (SKTUtils in this case). – Stanislav Pankevich Apr 05 '16 at 22:30
From what I see in SKTUtils, it is not written to play well with Objective-C. You can request support of it on their issue tracker or hack on its source yourself, though former is better of course. – Stanislav Pankevich Apr 05 '16 at 22:35
SKTUtils is not a project. It's just a directory with some swift files inside it, that's what I meant. – Ramy Al Zuhouri Apr 05 '16 at 23:02
I didn't get why my answer had got this -1. Please explain. – Stanislav Pankevich Apr 06 '16 at 14:08
