MainScheduler

public final class MainScheduler : SerialDispatchQueueScheduler

Abstracts work that needs to be performed on DispatchQueue.main. In case schedule methods are called from DispatchQueue.main, it will perform action immediately without scheduling.

This scheduler is usually used to perform UI work.

Main scheduler is a specialization of SerialDispatchQueueScheduler.

This scheduler is optimized for observeOn operator. To ensure observable sequence is subscribed on main thread using subscribeOn operator please use ConcurrentMainScheduler because it is more optimized for that purpose.

  • Initializes new instance of MainScheduler.
