Populating UIAlertController with UIAlertActions based on string array - arrays

Question

I've got a string array called languages, and I want to create as many UIAlertActions in a UIAlertController as there are elements in the array. I don't know how large the array will be, as the user can add languages to the array using the add option from the same UIAlertController.
loadLanguages() successfully loads userDefaults data into the languages array if there's any existing languages that've either been saved as the 2 starter languages on first app load and/or added by the user on subsequent uses of the app.
The add language option works, and is stored in userDfeaults (self.saveLanguages), and appended to the languages array.
However I'm not sure about creating UIAlertAction options for each language that is in the languages array. I've tried looping through the array to generate each menu item, as the languages array has the answer as to how many UIAlertActions should be displayed, but nothing appears.
After extensive searches I haven't come across anything covering this, but I'm sure there's an elegant approach.
FYI: languageChoiceButton is declared as:
var languageChoiceButton = UIAlertAction()
#objc func languageMenu(){
loadLanguages()
let chooseLanguageController = UIAlertController(title: "Vocabulary Tutor", message: "Choose a Language", preferredStyle: .actionSheet)
let addLanguage = UIAlertAction(title: "Add Language", style: .default, handler: { (action) -> Void in
let ac = UIAlertController(title: "Add a language", message: nil, preferredStyle: .alert)
ac.addTextField { textField in
textField.placeholder = "New language"
}
let submitAction = UIAlertAction(title: "Add", style: .default) { [unowned self, ac] (action: UIAlertAction!) in
self.newLanguage = ac.textFields?[0].text ?? ""
print("newLanguage: \(self.newLanguage)")
self.languages.append(self.newLanguage)
self.saveLanguages()
self.loadLanguages()
}
ac.addAction(submitAction)
ac.addAction(UIAlertAction(title: "Cancel", style: .cancel))
self.present(ac, animated: true)
})
chooseLanguageController.addAction(addLanguage)
for language in languages {
languageChoiceButton = UIAlertAction(title: language.capitalized, style: .default, handler: { (action) -> Void in
self.chosenLanguage = language
self.title = self.chosenLanguage.capitalized
print("Chosen language is: \(self.chosenLanguage)")
self.loadInitialValues()
chooseLanguageController.addAction(self.languageChoiceButton)
})
}
let cancel = UIAlertAction(title: "Cancel", style: .cancel) {
(action:UIAlertAction!) in
print("Cancel button tapped")
}
chooseLanguageController.addAction(cancel)
self.navigationController!.present(chooseLanguageController, animated: true, completion: nil)
}

Answer 1

Try to make an array while using certain languages and make a loop afterwards to add each of them to the alerts.
#objc func languageMenu(){
loadLanguages()
let chooseLanguageController = UIAlertController(title: "Vocabulary Tutor", message: "Choose a Language", preferredStyle: .actionSheet)
let i = languages.count - 1
for n in 0...i{
chooseLanguageController.addAction(UIAlertAction(title: arrayLanguage[n].language, style: .default, handler: { (action) in
print(self. languages[n])
}))
}
self.present(chooseLanguageController, animated: true, completion: nil)
}
