ios - WatchKit : error while communicating with the phone app -

-

i trying communicate iphone app. on watch controller have following code:

 func requestdatafromphone(messagetext: string) {         var infodictionary = dictionary<string,string>()         infodictionary["getappointmentstring"] = "message"         wkinterfacecontroller.openparentapplication(infodictionary) {             (replydictionary, error) -> void in             println("we made it!")             if let castedresponsedictionary = replydictionary as? [string: string],                 responsemessage = castedresponsedictionary["message"]             {                 println(responsemessage)                 self.appointmentstring.settext(responsemessage)             }         }     }

on appdelegate of iphone app , have code :

 func application(application: uiapplication, handlewatchkitextensionrequest userinfo: [nsobject : anyobject]?, reply: (([nsobject : anyobject]!) -> void)!) {          let response = "appointment @ noon tomorrow"         let responsedictionary = ["message" : response]         if let infodictionary = userinfo as? [string: string],             message = infodictionary["getappointmentstring"]         {              reply(responsedictionary)         }         reply(responsedictionary)     }

i getting following error :

"error domain=com.apple.watchkit.errors code=2 \"the uiapplicationdelegate in iphone app never called reply() in -[uiapplicationdelegate application:handlewatchkitextensionrequest:reply:]\" userinfo=0x60800006b580 {nslocalizeddescription=the uiapplicationdelegate in iphone app never called reply() in -[uiapplicationdelegate application:handlewatchkitextensionrequest:reply:]}"

what missing here ? pointers helpful. thanks.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
