There are many good Youtube videos that covers Leetcode solutions which are primarily in Java and Python programming language. However, there are some that are Swift enthusiast or Apple platform developers that may not be entirely familiar with those languages like Java, Python, C++ and etc. My hope is to grow this channel, EverythingSwift to bridge that gap.

If you find these sort of videos helpful, please feel free to subscribe. Appreciate it lot! Thank you!

Thank you for this video, i understand that we are starting the array of prime numbers at number 2, but i don't not understand the while loop, or the Array(repeating: true, ). Can you explain this solution in writing ?
