NSStringFromClass([instance class])
should do the trick.
Solution 2 - Iphone
if all you want to do is test an object to see if it's a type of a certain Class
BOOL test = [self isKindOfClass:[SomeClass class]];
Solution 3 - Iphone
From within the class itself
-(NSString *) className
{
return NSStringFromClass([self class]);
}

OBJC:
NSStringFromClass([instance class])
SWIFT
From instance:
String(describing: YourType.self)
From type:
String(describing: self)

Just add a category:
NSObject+Extensions.h
- (NSString *)className;
NSObject+Extensions.m
- (NSString *)className {
return NSStringFromClass(self.class);
}
Then use the following code:
NSString *className = [[SomeObject new] className];
or even:
NSString *className = SomeObject.new.className;
To use it anywhere add the category to YourProject.pch file.

If you are looking how get classname in Swift you can use reflect to get information about object.
let tokens = split(reflect(self).summary, { $0 == "." })
if let typeName = tokens.last {
println(typeName)
}
