dispatch_source_cancelworks asynchronously, deallocating the dispatch source synchronously runs the risk of deallocating it beforedispatch_source_cancelhas completed, causing a crash.This PR sets a completion handler that holds a strong reference to the dispatch source to be deallocated, ensuring that the dispatch source is only deallocated after the
