Working with NSNumber in Swift

I just discovered that in Swift, NSNumber supports the Equatable protocol. That’s big news. It means we don’t have to do the ugly

In Objective C:

NSNumber *n1 = [NSNumber numberWithDouble:12.0];
NSNumber *n2 = [NSNumber numberWithDouble:12.1];

if ( [n1 isEqualToNumber:n2] ) {
    NSLog(@"Yes, the numbers match.");
}

In Swift:

let n1 = Double(12.0)
let n2 = Double(12.1)

if n1 == n2 {
    print ("Yes, the numbers match.")
}

I really like that!
