Swift3 optionals chaining in IF conditions bug?

Question

This code worked just fine in Swift 2.3 and I don\'t understand why I have to unwrap TestClass to check if number is bigger than 4. This is whole point of chain

Answer 1

This could also happen on Guard statement. Example:

var playerLevels = ["Harry": 25, "Steve": 28, "Bob": 0]

for (playerName, playerLevel) in playerLevels {

guard playerLevels > 0 else {//ERROR !!
    print("Player \(playerName) you need to do the tutorial again !")
    continue
}

print("Player \(playerName) is at Level \(playerLevels)")

}
