First of all please don't laugh at my question I am still a newbie. Recently I have started learning IOS development and found Dispatchqueue (documentation link: https://developer.apple.com/documentation/dispatch/dispatchqueue). After reading the documentation, I had a question on my mind. Is it similar like Flutter's Future(documentation link: https://api.flutter.dev/flutter/dart-async/Future-class.html)? Or are there any differences between them? If yes, then what are the differences? I was searching the whole internet but I could not find a proper answer which would clear my confusions. Thanks in advance.

DispatchQueue is for parallelization your tasks. It works according to the first in first out principle, means the first tasks will be done first etc. A Future sounds for me like a "delayed" task, means your task will be done in the future but not in the background like in a DispatchQueue. Some good information for DispatchQueue are here Appropriately-using-dispatchqueue-main :-)
