Difference between NSRange and NSMakeRange

The only difference between them is that

NSRange(location: 0, length: 5)

is an initializer for NSRange while

NSMakeRange(0, 5)

is a function which creates a new NSRange instance (by using the same initializer inside most likely) and actually is redundant in Swift. Swift has simply inherited it from Objective-C. I would stick to the former

Main difference is that

NSRange(location: 0, length: 24) 

is auto-generated struct init method in Swift and

NSMakeRange(0, 24) 

is just a predefined macro that setts location and length

NS_INLINE NSRange NSMakeRange(NSUInteger loc, NSUInteger len) {
    NSRange r;
    r.location = loc;
    r.length = len;
    return r;
}

In general, result is the same, but if you're Swift use first one and if you're writing ObjC code use second ;)
