Safari to merge search, address bars
Apple is seeding betas of Safari 5.2 and Xcode 4.4 to developers, reports say. The new version of Safari notably merges the search and address bars, imitating Google's Chrome browser. It also highlights the domain portion of a URL in the address bar, and uses a new Reader icon.
Xcode 4.4 is required to code for OS X Mountain Lion. A number of other upgrades have been made though, such as an editor for Collada 3D files, compiler support for Objective-C enhancements, and the ability to open a project in multiple workspaces. The Interface Builder has gained AppKit features such as auto-layout and trackpad zoom, and a new LLVM compiler should reduce idling time in apps, and aid overall software optimization.
Xcode 4.4 is a 1.7GB install package, and requires OS X 10.7.3 or Mountain Lion. Like Safari 5.2, developers must download the Xcode beta through the Mac Developer Center. Apple warns that installing the app into the Applications folder may cause problems trying to download earlier versions of Xcode through the Mac App Store; in that case a person can simply rename the beta file, or move it to a different folder.
