How do I call Objective-C code from Swift?

I am trying to implement audio visualizer to AVAudioPlayer from many days, tried different libraries but not succeeded. Now I found a library displayers but the problem is it's in Objective-C, now I don't know how to use it in the swift code. Here is the link of library https://github.com/agilie/DisPlayers-Audio-Visualizers. Please guide me in this regard or suggest me a good visualizer in Swift.
In order to use objective-c libraries or classes in a swift project you must use the bridging headers.
There's the apple documentation of importing this kind of project into a swift project:
https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_objective-c_into_swift
If you're still stuck you should follow this tutorial:

Other answers have said to use "Capabilities" in Xcode 6 to get a listing of the cocoa framework but I can't find any such thing in Xcode 6 menus. Is this a correct answer and if not how can I print out the cocoa framework so I can see what objects and methods are declared?
thanks!
I'm not sure if I get your question, but anyway Apple provides to us a well explained documentation that you can read: Mac Developer Library
For example you can read the NSView Class Reference or all the others Frameworks References.
If you just need the interfaces you could also from Xcode cmd+click on the class name to see the class interface.
But if you are also looking for private APIs, you should dump the Frameworks yourself or search them on GitHub, from who already did it for you.

I'm a newbie in programming and now I'm learning yii framework and it's really hard.
What does this declaration mean :
something::something
for instance : CHtml::encode, yii::appname, CHtml::dropDownList, etc...
Yii::app()->request->baseUrl;
CHtml::encode($data->getAttributeLabel
What does it actually means?
And do you guys have a recommendation for learning yii framework other than Larry Ullman's?
I really need a tutorial.
Thanks.
That is the part of language(PHP), also called scope resolution (::). Not only with YII, its common to all PHP framework. Please go with some PHP language manual first, its tutorials. Then only you will be comfortable with any PHP framework like YII.
For an iOS app that will eventually be ported to Android/Winphone, I would love to be able to write some re-usable libraries in c#, but author the iOS UI in traditional Obj-C and reference the library written in c# from Xcode and consume it from Obj-C.
I've found lots of docs that talk about going the other way via bindings (Obj-C -> C#), but not much pertaining to my question. Also, a similar question was asked 4 years ago here, but a lot has changed in the ecosystem, the info seems out of date, and some of the links in the answers now redirect elsewhere:
Is there a way to mix MonoTouch and Objective-C?
So, is this possible? If so how, and what's the best way to achieve it today? (Or alternately, is this a bad idea and should be abandoned?)
No, it is not currently possible to consume a C# library from Objective-C.
Note that it is usually possible to do it the other way with some ingenuity - the only real requirement is that the app must be a Xamarin.iOS app and the entry point the managed Main method. In your Main method you can call into native (C/Objective-C) code and have all your logic there.

What does the #package directive do in Objective-C?
I have only seen #package twice since starting iOS programming (and I've been doing this a while now).
What is #package used for? I believe it specifies where you can access variables from but I'm not sure of the exact rules?
It’s for cases when you write a portable library, the visibility level is then set to your library, but not for the other source code that will make use of it.

How to do the documentation in objective C?
Is it possible to write class/method documentation in Objective-C in a way that Xcode 4 displays them in the quick help, and/or generates a doc document from it in the style of Apple's own documentation?
Displaying it live - not that I know of.
But as for generating Apple like documentation, the best I have found is appledoc which I've been using for a year now. If accepts a wide range of commenting styles including Javadoc styles and can generate very Apple like documentation which it can also install directly into your Xcode help system.
I don't know if it still works for Xcode 4 but for Xcode 3 you could generate API doc sets using doxygen.
Apple has a set by step guide: Using doxygen to Create Xcode Documentation Sets on how to do it.
There is also the appledoc tool available from GitHub. Makes nice docsets.
