Animation not playing inside speech synthesizer delegate

I am totally new to iOS and I am working on an application that has many frame animations. Everything is going well until I try to do my final animation in a method that I am posting below. The method is a delegate assigned to the Built in Text to Speech synthesizer

func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didFinish utterance: AVSpeechUtterance) {
        if spoken == 0{
            spoken += 1
            print("speaking finished")
            self.ImageView.stopAnimating()
            self.ImageView.image = self.circleImages.last
            self.ImageView.animationImages = self.circleImages
            self.ImageView.animationDuration = 1.5
            self.ImageView.animationRepeatCount = 0
            self.ImageView.startAnimating()
            do{
                try self.recordAndRecognizeSpeech()

            }catch let error{
                print(error)
            }          
        }else if spoken == 1{
                //animation 1
                spoken += 1
                            //animation 1
                self.ImageView.image = self.comingOutImages.first
                self.ImageView.animationImages = self.comingOutImages
                self.ImageView.animationDuration = 6.0
                self.ImageView.animationRepeatCount = 1
                self.ImageView.startAnimating()
                print(String(self.comingOutImages.count) + " #of images")


                print("should have animated go in" + String(spoken))     
        }else{
            print("done")
        }

    }

The firs block of the method where spoken == 0, that animation works fine, but when it gets to the block where spoken == 1 that animation does not play it sets the image but it does not play the animation. Ive been looking around forever, I tried to run it on the main thread and a bunch of other things.

EDIT:

I have this method which is the animation right before the animation above that will not play unless set animationRepeatCount to 0, and if I set this animation to anything but 0 then the animation above plays but then this animation doesn’t play. In this method I have animation repeat count to 16 and then the above animation works but this one doesn’t. I would like to have this animation set to repeatCount 0 and when speech is done to fire the one above to repeatCount 1. Im very new to iOS and there is something I am just not getting right.

func handleSend(){
        if Thread.isMainThread{
            print("send on main thread")
        }else{
            print("send not on main thread")
        }
        do{
            try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
            try AVAudioSession.sharedInstance().setActive(true)

        }catch{}
        //UIView.animate(withDuration: 4.0, animations: {
            //animation 2
            print("second animation")
            self.imageView.stopAnimating()
            self.imageView.image = self.talkingImages.last
            self.imageView.animationImages = self.talkingImages
            self.imageView.animationDuration = 0.25
            self.imageView.animationRepeatCount = 16
            self.imageView.startAnimating()
            print("should have animated")


        //})
        let utterance = AVSpeechUtterance(string: self.finalString)
        //utterance.voice = AVSpeechSynthesisVoice(language: "en-GB")
        //utterance.rate = 0.1


        self.synthesizer.speak(utterance)

    }
