The Apple Developer portal has gone down ahead of Apple’s WWDC event later today, where Apple will announce its next-generation software platforms for Apple Watch, iOS and OS X. Posters from within the venue show that Watch OS will feature prominently as a newly rebranded as ‘watchOS’.

Update: The Beta Software Program page has also gone down — potentially indicating that iOS 9 or OS X 10.11 will be made available as public betas today.

iOS 9, OS X 10.11 and watchOS will all require new SDKs and development tools for developers which is likely the cause for the developer portal going down. A new version of Xcode (following historical tradition) and Swift is also expected with the official Swift account teasing that they had something in the works a few days ago.

It’s also worth noting that the Apple Online Store isn’t down … which probably indicates no new hardware announcements today, inline with expectations.

Sorry we’ve been quiet for a while. Working on something…
