how to create non duplicated random numbers - Xcode [duplicate]

This question already has an answer here:

• iOS: How do I generate 8 unique random integers? 5 answers

I am creating a random number game that has 9 different numbers and i want to randomise the numbers so they are randomised with non duplicates (e.g., 1,4,2,3,6,5,9,7,8) but at the moment i am just getting 9random numbers between 1 and 9 with multiple duplicates. Can anyone suggest anything without changing the existing code too much.

Thank you.
