Base and Derived Classes:

class BaseClass{    class func staticMethod(){        println("BaseClass.staticMethod")    }        class func staticMethodWithSelfCall(){        self.staticMethod()    }        func instanceMethodWithStaticCall(){        self.dynamicType.staticMethod()    }}class DerivedClass : BaseClass{    override class func staticMethod(){        println("DerivedClass.staticMethod")    }}

Test Code:

    BaseClass.staticMethod()    DerivedClass.staticMethod()        BaseClass.staticMethodWithSelfCall()    DerivedClass.staticMethodWithSelfCall()        BaseClass().instanceMethodWithStaticCall()    DerivedClass().instanceMethodWithStaticCall()

Output:

BaseClass.staticMethodDerivedClass.staticMethodBaseClass.staticMethodDerivedClass.staticMethodBaseClass.staticMethodDerivedClass.staticMethod
