Hours after Apple released a candidate golden master version of OS X Yosemite to developers and members of the public beta, the Cupertino company has begun asking developers to begin submitting their Yosemite apps to the Mac App Store. Additionally, developers can now submit their apps written in Swift to the Mac App Store as well.

Make sure your apps take advantage of all the great new features in OS X Yosemite, which will be available to millions of customers around the world later this fall.

Add powerful new functionality throughout OS X Yosemite with app extensions, explore the innovative new Swift programming language, and take advantage of advances in game technologies, Safari, iCloud, and more. To prepare your apps for the Mac App Store, download and build with the OS X Yosemite GM candidate and Xcode 6.1 GM seed from the Mac Dev Center. With the latest releases, Swift is now final and you can submit your Mac apps written with Swift to the Mac App Store.
The public release of the new OS is expected in late October and will include a redesigned interface and new features like Continuity, iCloud Drive and more.

Thanks Justin!
