TealiumDispatchGroup

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.


                    
                    
                    init(queue:)

Creates a new dispatch group with the specified queue.

Declaration

Swift

public init(queue: TealiumQueue)

Parameters


                                queue

The queue on which to execute operations.


                    
                    
                    parallelExecution(_:completion:)

Executes multiple operations in parallel and collects their results.

Declaration

Swift

@discardableResult
public func parallelExecution<Result>(_ works: [(@escaping (Result) -> Void) -> any Disposable], completion: @escaping ([Result]) -> Void) -> any Disposable

Parameters

`works`	An array of work items that take a completion handler.
`completion`	Called when all work items complete with their results.

Return Value
