我想在我的应用程序中集成Siri / Intent扩展,目前基于
Swift 2.3.我正在使用Xcode 8 beta 6版本.
该应用程序甚至无法编译,发出错误
Type ‘IntentHandler’ does not conform to protocol ‘INSendMessageIntentHandling’
Protocol requires function ‘handle(sendMessage:completion:)’ with type ‘(sendMessage: INSendMessageIntent,completion: (INSendMessageIntentResponse) -> Void) -> Void’
Objective-C method ‘handleWithSendMessage:completion:’ provided by method ‘handle(sendMessage:completion:)’ does not match the requirement’s selector (‘handleSendMessage:completion:’)
即使是来自Apple的示例应用程序,UnicornChat也无法使用相同的错误进行编译.我确实将SWIFT_VERSION标志更改为是,以支持Swift 2.3
示例代码：
func handle(sendMessage intent: INSendMessageIntent,completion: (INSendMessageIntentResponse) -> Void) {
let userActivity = NSUserActivity(activityType: NSStringFromClass(INSendMessageIntent.self))
let response = INSendMessageIntentResponse(code: .Success,userActivity: userActivity)
completion(response)
}
这失败并出现上述错误.
任何人都知道如何让Siri在Swift 2.3中工作？
解决方法
所以,这有帮助

我们需要使用Swift定义@objc方法签名.如下面的作品.
@objc (handleSendMessage:completion:)
func handle(sendMessage intent: INSendMessageIntent,completion: (INSendMessageIntentResponse) -> Void) {
//..
}
