Download available for Mac and iPhone devs
Apple has released a third preview of Xcode 4, the latest set of developer tools for Mac OS and iOS platforms. Version 4 transitions to a single-winder interface, combining a navigation toolbar, which offers search and list content, with a Jump Bar that can be used to quickly switch between various levels.
The company released the previous preview late in July, while the iOS 4.1 gold master was seeded to developers earlier this week. The third preview is now available for Mac and iPhone program members. A release date for the final version of Xcode 4 remains unknown.
