Hi everyone. My question is all about deep understanding of my code. For expamle i write :

print(“Hi there!”)

I know that it the output will string saying “Hi there!”, but i dont know how the print function works. Where can i get information about this?

If you want to find out what arguments the print function takes, you can do that easily in Xcode. Position the cursor over the function name print and then option-click to display a popup window. From there, follow the links for more information.

If, however, you are after the source code for the print function itself, start from swift.org.
