TealiumDispatchGroup Class Reference

public class TealiumDispatchGroup

A utility class that wraps a DispatchGroup and makes safer to use and includes an array of results in the completion.

Differently from the DispatchGroup, if the first work completes synchronously the completion won’t be called until all the other work is completed too. All the results then are collected and returned in the completion.
