iOS - Is there a way to detect popular keywords from a user's text input and sort by popularity or trending?

Question

I am building an app that will allow users to type into a UITextInput field. I want to be able to scan what they type and extract possible keywords/phrases that could be used to populate other things in the app, and also have them sorted by popularity/trending.

Example:

1. The user types the following string into the input: "My siblings are so embarrassing and I can't wait for them to leave me alone!"
2. Expected Keyword Extraction: "siblings, embarrassing, alone,..."
3. Expected Keyword Sorting by Popularity/Trend: "embarrassing, siblings, alone,..."

Is there an SDK or native iOS solution for this?
