Looping through NSMutableArray in Swift

How can Ioop through an NSMutableArray in Swift? What I have tried:

var vehicles = NSMutableArray()

The array contains objects from class: Vehicle

for vehicle in vehicles {
    println(vehicle.registration)
}

I cannot run the above code without the compiler telling me registration doesn't belong to AnyObject. At this point I assumed that was because I hadn't told the for loop what type of class item belongs to. So I modified by code:

for vehicle: Vehicle in vehicles {
    println(vehicle.registration)
}

Now the compiler complains about downcasting... how can I simply gain access to the custom registration property whilst looping through the array of Vehicles?
