As part of our continuing work to expand and maintain our catalog of supported OS X and Xcode versions, we are shipping a couple updates in our OS X infrastructure offerings.

Time for a new default

To help improve your experience when using OS X in your builds, we are going to promote our Xcode 8.3 image to be our default build environment image on Wednesday 15 November 2017 Tuesday 28 November 2017.
For more detail on the updated schedule, see our Xcode8.3 announcement

We are also updating this image with some changes that will improve the experience of these builds. We are adding brew update, pod repo update, and other similar updates to help speed up build times, and we are upgrading the OS X version of this image to 10.12.6 (from 10.12.5) to allow users to take advantage of newer OS X features and applications.

This updated 10.12.6 Xcode8.3 image will be released on Wednesday 25 October 2017 in order to give you all time to test it before we promote it to be the new default.

In a few days, we’ll be publishing some more information about the new default environment, including a detailed comparison in software versions between our Xcode 7.3 images and the new Xcode 8.3 image. Stay tuned!

Retiring some older images

In order to streamline our image catalog, on 15 November 2017 we will be simplifying our image offerings to the following:

• osx_image: xcode9.1
• osx_image: xcode9
• osx_image: xcode8.3 (Default)
• osx_image: xcode7.3
• osx_image: xcode6.4

The following images will be deprecated:

• osx_image: xcode8.2
• osx_image: xcode8.1
• osx_image: xcode8

We may extend this time period based on user feedback, and we will begin displaying a warning message on top of the build log to those of you who have explicitly chosen one of the Xcode versions that will be deprecated in the last week of October.
