Hi, I am currently facing trouble using Xcode for the first time. Previously I used lightweight online IDEs but now I feel the need to switch to an offline one. Since I use Mac I wanted some help on how to setup Xcode for CP. Also while copying large test cases from udebug I see Xcode is not able to run on them and provide the required output. And another problem I have been facing is using the header bits/stdc++.h in Xcode. I searched for a solution online and did something like this 52770619 but over here it showed compilation error.

I would be very happy if anyone can help me.
