Swift 3 Value of type 'Any?' has no member 'object'

I have updated swift 3 and I found many errors. This is one of them :


Value of type 'Any?' has no member 'object'


This is my code :

jsonmanager.post( "http://myapi.com",
parameters: nil,
success: { (operation: AFHTTPRequestOperation?,responseObject: Any?) in
if(((responseObject? as AnyObject).object(forKey: "meta") as AnyObject).object(forKey: "status")?.intValue == 200 && responseObject?.object(forKey: "total_data")?.intValue > 0){
let aa: Any? = (responseObject? as AnyObject).object(forKey: "response")

self.data = (aa as AnyObject).mutableCopy()
}


New Error Update :


Optional chain has no effect, expression already produces 'Any?'


And


Cannot call value of non-function type 'Any?!'


It works well in previous version 7.3.1 swift 2.

This is json response :

{
"meta":{"status":200,"msg":"OK"},
"response":[""],
"total_data":0
}

Answer

Unlike Swift 2, Swift 3 imports Objective-C's id as Any? instead of AnyObject? (see this Swift evolution proposal). To fix your error, you need to cast all of your variables to AnyObject. This may look something like the following:

jsonmanager.post("http://myapi.com", parameters: nil) { (operation: AFHTTPRequestOperation?, responseObject: Any?) in
    let response = responseObject as AnyObject?
    let meta = response?.object(forKey: "meta") as AnyObject?
    let status = meta?.object(forKey: "status") as AnyObject?
    let totalData = response?.object(forKey: "total_data") as AnyObject?
    if status?.intValue == 200 && totalData?.intValue != 0 {
        let aa = response?.object(forKey: "response") as AnyObject?
        self.data = aa?.mutableCopy() 
    }
}
