We have added support for Xcode 7.3 Beta to our OSX containers. CircleCI customers can build their apps using Xcode 7.3 Beta. Full support for Xcode 7.3 Beta allows OS X developers using CircleCI to build and test their code for iPhone, iPad, Mac, and Apple Watch apps with the most current tools available. We also recently updated the developer tools on our container to latest versions. These tools include CocoaPods, Fastlane, Carthage and XCTool.
