Apple releases fourth beta of macOS Catalina to developers

In addition to new betas of iOS 12.4 and more, Apple today has also released the fourth developer beta of macOS Catalina. This update comes two weeks after Apple released the third developer beta of the update.

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.
