While Apple has released the fourth developer beta of macOS Catalina, the fourth developer betas of iOS 13 and watchOS 6 are nowhere to be found. They might still come later today, or Apple could be waiting a bit longer.
Of note, Apple is warning developers about one major incompatibility in the fourth beta of macOS Catalina:
Using Xcode 11 beta 3 with macOS Catalina beta 4 will prevent SwiftUI previews from working. Update to Xcode 11 beta 4 when it becomes available.
