Calling NSStringFromClass on a Swift Class in Objective-C returns module mangled name

Question

I am aware of this question regarding how we can get a readable class name of an objective-c class in Swift.

What I want to achieve is getting the readable class name of a Swift class from inside objective-c without mangling the class name with the module.

So if I have a Swift class:

class Foo: NSObject{}

Then inside Objective-C I would love to use the convenient NSStringFromClass to convert the class name to a string.

I would expect NSStringFromClass([Foo class]) to return @"Foo" but instead it returns @"Bar.Foo" withBarbeing the module name.

I came across this Gist but it seems a little hacky and messy, is there a better way? Something that doesn't include typing the class name manually into a string would be preferred.

Answer 1

BEFORE SWIFT 2.1:

Just put @objc(YourClassName) in your swift class:

@objc(YourClassName)

class YourClassName: NSObject {

}

And you can use NSStringFromClass like this:

NSStringFromClass(YourClassName.self)

It should also work from Objective-C then.

SWIFT 2.1

With Swift 2.1 a comment to this answer states that this is sufficient:

class YourClassName: NSObject {

}

And just use:

var str = String(YourClassName)

I have not tested this from Objective-C code myself though.

There's been a edit-suggestions that want to use this instead for Swift 4:

var str = String(describing: YourClassName.self)

I've not tested this from Objective-C though.
