Type objectId to Parse Cloud Code

Question

I'm trying to pass some parameters to my Parse Cloud Code function, and receive the following error message in Xcode. cannot convert value of type '[String : String?]' to type '[NSObject : AnyObject]' in coercion. It works fine until I reference the incomingUser.objectId. Here's the code I'm passing:

let params = ["userType" : userType, "recipient" : self.incomingUser.objectId]

PFCloud.callFunctionInBackground("pushNotification", withParameters: params as [NSObject : AnyObject]) {
    (res: AnyObject?, error: NSError?) -> Void in
      print(res)
      print(error)
}

Thanks for any help you can provide.

try use params as [NSObject: AnyObject?] instead.

Or if the API require [NSObject: AnyObject], you would have to unwrap the objectId first.

guard let objectId = self.incomingUser.objectId else { return }

And then do

let params = ["userType" : userType, "recipient" : objectId]

PFCloud.callFunctionInBackground("pushNotification", withParameters: params as [NSObject : AnyObject]) {
(res: AnyObject?, error: NSError?) -> Void in
    print(res)
    print(error)
}

The guard statement worked for this. Would you mind explaining why the "unwrapping" is required? Thanks so much for the help! – Robert Mar 07 '16 at 01:29
I would recommend [this](http://stackoverflow.com/questions/24034483/what-is-an-unwrapped-value-in-swift) answer for reference. I'm not quite good at explaining things in English:P. But let me know if you have any other puzzle after reading the above answer. – J.Wang Mar 07 '16 at 01:34
