2,266 Pointsunwrapping two optionals assigned to one if let statement
Hey,
So if i have some code as written below
func currentWeatherDictionaryfromjsonDictionary (jsonDictionary: [String: AnyObject]? ) -> CurrentWeather? { if let currentWeatherama = jsonDictionary?["currently"] as? [String: AnyObject] {...
Now there are two optionals in the if let statement, the first is jsonDictionary? and the second is the optional returned from accessing the dictionary which is casted to an optional(since the key might not exist)
the question is which optional does this if let statement unwrap, or is it both?
I thought it would have been to unwrap only the second optional but when i played around in the playground it seemed like jsonDictionary was unwrapped as well.
