Then how NSMutableDictionary.addEntries() solve this issue?
I thought with Swift design, we could merge some compatible dictionaries simply
by using + operator array.

Hi Mr Bee,
The reason I don’t think it is provided is because it is difficult to know what
to do when keys collide. You could easily write such a thing and decide your
own policy. For example:
let d1 = ["Apples": 20, "Oranges": 13]let d2 = ["Oranges": 3, "Cherries": 9]
extension Dictionary { func merged(with another: [Key: Value]) -> [Key:
Value] { var result = self for entry in another {
result[entry.key] = entry.value } return result }}
let result = d1.merged(with: d2)

Hi,
I'm using Swift v3 on an El Capitan machine. I want to merge a dictionary into
another compatible dictionary. However, I couldn't find addEntries function in
the dictionary instance, like it was on NSMutableDictionary
(https://developer.apple.com/reference/foundation/nsmutabledictionary).
Does that mean that Swift standard library won't provide such similar function
for native Swift dictionary? Or is there any other way of doing that natively?
I mean using the built-in Swift's native dictionary function
(https://developer.apple.com/reference/swift/dictionary), no need to write a
custom function, or bridging to NSMutableDictionary.
Thank you.
