Flappy Bird in Swift

Re:Flappy Bird in Swift by josephlord on Tuesday June 03, 2014 @09:50PM (#7843629)

  if var == true {...}

In some languages var might be truthy but not equal to true. The falsy values may be more of a problem at times.

However in the strongly typed swift I don't think it will be a problem as I suspect (but haven't read/tested enough yet to confirm) that only false and nil will be falsy and that comparison with true will throw errors if var isn't of bool type.

Just tried it. In Swift:

  3 == true    // Give an error (operator overload doesn't cover this)
  true == 3    // Returns false
  nil == false // Returns false

You can't use nil or integers directly in an if statement without a function to return a logic value.

Yes, such languages exist, and even in C++ if (x == true) is different from if (x), given that x is any number kind other than boolean, but my comment was only for the case when the two would be equivalent.
