554 PointsError in exercise, can't solve it by myself
Where is the mistake?
let currencies = ["US":"Dollar", "UK": "Pound", "JP": "Yen"] let ukCurrency = currencies.removeValueForKey("UK")
var todo = ["Learn Swift", "Build App", "Deploy App"]

18,813 PointsBecause the exercise had us define the dictionary as a constant - with let
- it can't be changed with .removeValueForKey()
. Besides, the exercise doesn't ask you to remove the value anyway. (Although you are correct that it would have returned the value and so the variable would have been assigned the right value. Bonus point for remembering that!)
You just want to assign the value:
let ukCurrency = currencies["UK"]
