Swift - How to collect "diamonds", add "diamonds" to "diamonds? - ios

Question

I am making a game that when the player collides with diamonds it will add one to the diamond score and if they play again the current diamond score will add onto the previous one. If the user closes the app I want the diamonds to remain the same and not reset.
So far, I have made the diamonds spawn and move along with the game, but when it collides it says game over. I don't want that.
Question 1 - I want to know how to make the player collide with diamond and collect it (removeFromIndex) I'm guessing, whilst adding +1 to the diamond score
Question 2 - I want to know how to make the currect diamond score add onto the overall score. So if the user has 5 diamonds and plays again and collects 4 diamonds the total diamonds the user should have is 9 diamonds
