swift 3 update syntax from swift 2

Question

in swift 2.2 its work:

var messages = [JSQMessage]()

//...
for i in 1...10 {
 let sender = (i%2 == 0) ? "Server" : self.senderId
 let messageContent = "Message nr. \(i)"
 var message = JSQMessage(senderId: sender, displayName: sender, text: messageContent)
 self.messages += [message] //Cannot convert value of type '[JSQMessage]' to expected argument type 'inout_'
}

in swift 3 give me error. tried to use

self.messages += [&message] // Type of expression is ambiguous without more context

how to fix?

@JAL: That thread shows alternative solutions, but I don't see why `messages += [message]` should not compile. — Martin R, Oct 22 '16 at 17:35
Compiles fine for me – perhaps try cleaning your build folder? Usually you get that kind of error when `message` is optional, although that doesn't appear to be the case here. — Hamish, Oct 22 '16 at 18:01

Try this: self.messages.append(message)

There are a lot of variants of appending:
