Is this bad?

on 4:03 the line of code written on the bottom, "request', gives me a warning with a white circle in it and says: "Initialization of immutable variable 'request' was never used; consider replacing with assignment to '_' or removing it." I don't know what it means but it would be really helpful if i could at least know if its fine if I keep it like it is.

Xcode throws these warnings often but I wouldn't worry to much, some times you may have a variable that was never mutated and Xcode may throw a warning asking you to change it to a constant. Search the apple documentation or the web for some more possible information on the warnings. hope this helps ! James
