swift 3 更新 swift 2 的语法

Question

在 swift 2.2 中它的工作原理:

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_'
}

在 swift 3 中给我错误。尝试使用

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

如何解决？

Answer 1

试试这个:self.messages.append(消息)

附加有很多变体:
