What should the scheduler be for delay and debounce in Combine? (Xcode 11 beta 1 only)

Question

This issue would ideally be deleted because it is related to obsolete beta version of Xcode only.

[WWDC Video 721 Combine in Practice][1] seems to indicate that RunLoop.main should be a valid scheduler to use in Combine with delay or debounce but I'm seeing compile errors with Xcode claiming that RunLoop doesn't conform to scheduler. Am I doing something wrong or is this just an issue with the first beta of Xcode.

ContentView.swift:95:77: error: argument type 'RunLoop' does not conform to expected type 'Scheduler'
        return delayPublisher.debounce(for: .seconds(5), scheduler: RunLoop.main).eraseToAnyPublisher()

I've raised FB6160439.

Answer 1

The Foundation Combine integrations weren't available in the first beta build. They're available in the second beta (6/17/19), so you just need to update your Xcode 11 beta.
