Initialize dictionary from array with Swift 3

Question

Is there a more simple/efficient way to initialize a dictionary from an array in Swift 3?

for object in array {
    dict[object.id] = object
}

Nothing wrong with the above but I was wondering if you could use map/reduce/etc to do this with slightly less code.

Answer 1

array.forEach({ object in
    dict[object.id] = object
})

or shorter:

array.forEach({ dict[$0.id] = $0 })
