Create jpeg image from imageView.image in swift

Question

I am working on an app where the user has to register. In this process, you can choose a profile image. The process is like this: You tap on the imageView, the imagePicker opens (you can select from camera or gallery) and after you choose an image, the picker closes and the image is loaded into the imageview. Now the question is, how can I create an jpeg from the imageView.image, so that i can upload it via Alamofire to the backend?

here the Code:

When Image is selected via picker:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
        //previewImage is the imageView where the image is displayed
        previewImage.image = pickedImage
        previewImage.layer.cornerRadius = 55
        profileView.translatesAutoresizingMaskIntoConstraints = false
        profileImageView.isHidden = true
    

        UserData.shared.profilePicture = previewImage.image!
    }
    dismiss(animated: true, completion: nil)
}

And here the method which uploads the image:

    func uploadImage(profileImage: UIImage) {
    
    let image = profileImage.jpegData(compressionQuality: 0.5)
    let filename = getDocumentsDirectory().appendingPathComponent("profile.jpeg")
    try? image!.write(to: filename)
    
    
    AF.request(Constants.uploadProfileUrl, method: .post, parameters: ["profile": UIImage(named: "profile")], headers: ["Content-Type":"multipart/form-data", "Authorization": "Bearer "+Configuration.accessToken]) { urlRequest in
    }.response { response in
        print(response)
        switch response.result {
        case .success:
            self.performSegue(withIdentifier: Constants.successfulRegister, sender: self)
        case .failure(let error):
            let statusCode = response.response?.statusCode
            print(statusCode)
            print("fail")
        }
    }
}

Somehow I get an success message from alamofire but the image is not shown in the backend.

try it :-

• take a global variable for UIImage
• store the picked image in that variable
• send that image in alamofire (compress if needed)

let image = UIImage()

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
        self.image = pickedImage
        previewImage.image = pickedImage
        previewImage.layer.cornerRadius = 55
        profileView.translatesAutoresizingMaskIntoConstraints = false
        profileImageView.isHidden = true
    

        UserData.shared.profilePicture = previewImage.image!
    }
    dismiss(animated: true, completion: nil)
}
