An NSString object can be initialized from or written to a C buffer, an NSData object, or the contents of an NSURL . It can also be encoded and decoded to and from ASCII, UTF–8, UTF–16, UTF–32, or any other string encoding represented by NSStringEncoding .
NSString : Creates objects that resides in heap and always passed by reference. String: Its a value type whenever we pass it , its passed by value. like Struct and Enum, String itself a Struct in Swift.
(NSString *) is simply the type of the argument - a string object, which is the NSString class in Cocoa. In Objective-C you're always dealing with object references (pointers), so the "*" indicates that the argument is a reference to an NSString object.
Use Character class
var chars = [Character](str)
