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.


Getting Started with Xcode 7.3

To start using Xcode 7.3 beta now you can add the following to your circle.yml:

    version: “7.3"

As of February 10th, 2016, the image contains Xcode 7.3 beta 2. We will ​update​ the image with newer beta versions, and eventually with the full release version.

We have docs explaining how to select an Xcode version in your circle.yml here.

The image has the following versions of tools pre-installed:

  • Facebook xctool 0.2.7
  • CocoaPods 0.39.0
  • xcpretty 0.2.2
  • fastlane 1.57.0
  • carthage 0.12.0
  • shenzhen 0.14.2

We recently published a 5-step guide that will help you to set up code-signing and deployment of your app, using CircleCI. Check it out and let us know what you think:
