I'm trying to implement a ViewController feature to edit and save Profiles with the help of Firebase but, I get the error: Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value when using this code below:
@IBAction func saveButton(_ sender: Any) {
var data = Data()
data = profileImage.image!.jpegData(compressionQuality: 0.1)!
DataService.dataService.SaveProfile(username: usernameTextfield.text!, email: emailTextfield.text!, data: data as NSData)
}

You may use following ( if let statements ) to check optional value errors.
@IBAction func saveButton(_ sender: Any) {
var data = Data()
if let image = profileImage.image {
if let data = image.jpegData(compressionQuality: 0.1) {
DataService.dataService.SaveProfile(username: usernameTextfield.text!, email: emailTextfield.text!, data: data as NSData)
}
}
}

@potatoonion because you don't have a valid image in the image view.

It's your image view. You should store an image there?

I tried store a image but nothing still happens when I click on the save button, thought it's also the username and email textfields that don't save either when I try to change it. Maybe something is wrong with the button?
