ios8 swift开发：显示变量的类名称

var ivar = [:]
ivar.className // __NSDictionaryI

var i = 1
i.className // error: ‘Int‘ does not have a member named ‘className‘

If you want to get the type of a primitive, you have to use bridgeToObjectiveC(). Example:

var i = 1
i.bridgeToObjectiveC().className // __NSCFNumber


println("\(object_getClassName(now))");
