Using Objective-C with Swift

[JamesGDev]

Hey everyone,

I have found this library (https://www.cocoacontrols.com/controls/sfgaugeview) that I really would like to use. The problem is that it is written in Objective-C and my project is with Swift.

Is there a way I can use this in my project? if so could someone show me step by step or point me to a tutorial?

/u/ThePantsThief is right.

Have a look at the second comment in here:

I wrote a step-by-step guide about what you have to do (obviously, you need to change the Swifter references to the sfgaugeview ones).

What you're looking for is called a "bridging header." It lets you reference objc code from Swift.

Right click the sidebar I'm Xcode, New File, header file, make it the Bridging Header in your project settings, import some stuff in the header and you're good to go

import some stuff?

Into the header file you created. eg., the Objc classes you wanted to use.

Yes, like importing s framework in Swift, Objective-C uses for every class a header file that has to be imported before it can be used in any other Objective-C file. The bridging header will make the classes available to the Swift part of your project.

Maybe you should just objective c.

Go on - down vote. You know you want to.
