It's that time again. If you're on the developer beta for iOS 13, iPadOS 13, watchOS 6, or tvOS 13, it's time to check for updates. Apple today released the fourth developer betas for each of them today.
If you're looking for the fourth developer beta of macOS 10.15 Catalina, that was actually released yesterday. You might recall that that build actually broke SwiftUI previews, so today there's a new beta for Xcode 11 that should fix that.
Apple hasn't yet published any release notes for today's new builds. However, it's pretty safe to assume that they include mostly fixes and some minor UI polishes. As is typically the case, the overall experience gets a bit better with each beta build.
All of these updates are slated to be released in late September, with the GM seed being offered a few weeks before that. Now that we're around the halfway point, these betas should be getting easier to use, with fewer headaches. If you're on the public beta, you should see this build soon. The last couple of public betas have arrived about a week later.
