I am getting crash on button click

        let requester = VNRecognizeTextRequest { request, error in
            guard let observations = request.results as? [VNRecognizedTextObservation] else {
                fatalError("Received invalid observations")
            }
            
            for observation in observations {
                guard let bestCandidate = observation.topCandidates(1).first else {
                    print("No candidate")
                    continue
                }
                if bestCandidate.string.contains(".") {
                    self.allTextString.append(" \(bestCandidate.string)")
                }
                print("Found this candidate: \(bestCandidate.string)")
            }
            if self.allTextString == "" {
                 self.showActionSheetTitleMessageOnMainThread("Temperature not found", message: "")
            } else {
                 self.TempratureValue.text = self.allTextString
            }
           
        }
        
        let requests = [requester]

While creating an array of the requester variable. On Simulator code works fine. And memory to requester is allocated , But when running on device requester memory is uninitialised.
