I am trying to make a simple flashcard app. 

OVERVIEW - To give you the basic run down of the app, all of the flashcards contain an object that has the letter l. Sometimes the word starts with the letter l, sometimes there is a double ll, sometimes the word starts with pl or kl, or sl, etc... 

SO FAR - I have made the app so that there is a home page and from the home page you press Go and then it takes you too a second view controller. From there you can swipe left and right through the flash cards. I did this by creating an array with all of the images and then adding a swipe gesture (code below)

THE PROBLEM - I want to create a settings page. This settings page will have a basic on and off switch for each group of words. So lets say I do not want any words that have the initial letter l, I would turn the button too the off position and then when I swipe through the images there will be no flashcards with the initial letter l. 

[settings page](https://i.stack.imgur.com/qpzkl.png)

MY IDEA - I imagine that i will have to connect each on and off switch too its corresponding array of words and then code up if, then statements for each button. Then add all of the arrays together. However im not sure at all how to begin doing this. I have made a Table view with all the different on and off switches but have not yet added any functionality. I am also not sure how I am going to send the information from my table view to the second view controller. 

I know this is alot to ask in one question but any help would be much appreciated. Thank you
