I am aware that there is a Translate function in a text menu in UITextView in iOS
(see for example Remove Translate and share options from selection menu on textview in xamarin).
I would like to use this function by myself without using the Translate menu. For example, I would like to translate an entire sentence displayed in a UITextView instead of translating only the selected parts.
Is there a specific func that we can use? How can I call this function?
Apple's translate API is not available to the public.

You can use Google's GoogleMLKit/Translate instead.
ML Kit on iOS.Add GoogleMLKit/Translate in your podfile by running the following command in the terminal.
pod 'GoogleMLKit/Translate', '3.1.0'
Read the Instal the Getting started section on https://cocoapods.org/ if you have not set cocoapods or you do not know how to do so.
Google has written a very good sample code. It is straight forward. Read from the Translate a string of text section onwards.
