DispatchGroup in Swift

Updated 30 November 2022


In this blog, we will learn about dispatchgroup


Dispatch groups allow us to monitor multiple tasks as a single unit. All set of tasks and synchronizes behaviors in the group. We add tasks to a group by making balanced calls to enter() and leave(). When all tasks finish executing, the group executes its completion handler. You can also wait synchronously for all tasks in the group to finish executing.

It will help the developer to execute multiple tasks at the same time

you will get the result synchronously when the task will complete it will notify that the task has complete

for example

In the above example, enter() will initialize the dispatch group for the test1

once the operation starts then enter function will call and when it will complete then leave fuction will executed

all functions will call separately if some function takes some extra time then another function will be executed

if you have only one function then no need to call the dispatch group

this thing will happen with the API call also

in the case of the API

Please click here to check more detail about it

In the above example if API call depends on another api response then this case will better solution
