Dictionary is not convertible to Void

Hi guys I've been searching the net without much luck but I'm trying to get around Alamofires asynchronous nature. I'm trying to return the JSON response as a dictionary but Xcode is giving me "Dictionary is not convertible to 'Void'"

func homePageDetails(userName:String) -> (Dictionary<String,AnyObject>){
    let username = userName
    let hompePageDetails = Alamofire.request(.GET, "http://example.com/API/Bunch/GetHomePageDetails/\(username)/").responseJSON{(request, response, JSON, error) in
    print(JSON)
    var test = JSON as Dictionary<String,AnyObject>
    return test
    }
}

Any help would be greatly appreciated.

You are returning test: Dictionary<String,AnyObject> from closure and not from homePageDetails method. Closure return type is Void, thats why you get this error.

I haven't used Alamofire myself, but Alamofire.request seems like non-blocking call. If its so you cannot return from this function. You can use something like completion closure. Non tested concept:

func homePageDetails(userName:String, completion:(Dictionary<String,AnyObject>) -> Void) {
    let username = userName
    let hompePageDetails = Alamofire.request(.GET, "http://example.com/API/Bunch/GetHomePageDetails/\(username)/").responseJSON{(request, response, JSON, error) in
        print(JSON)
        var test = JSON as Dictionary<String,AnyObject>
        completion(test)
    }
}
