Attention macOS / Xcode image users!

In line with our Xcode Deprecation Policy we will be removing a number of Xcode images in preparation for Xcode 14. This means that certain older images spanning across Xcode 10, Xcode 11, and Xcode 12 will not be available after 2nd August 2022.

The following images are due to be removed from our platform on 2nd August 2022:

* Xcode 10.3.0
* Xcode 11.4.1
* Xcode 11.5.0
* Xcode 11.6.0
* Xcode 12.0.1
* Xcode 12.1.1
* Xcode 12.2.0
* Xcode 12.3.0
* Xcode 12.4.0

To facilitate with awareness we are commencing with two brownout sessions; a first on the 6th July 2022, and a second on 19th July 2022. On both days the above images will not be available within the following three time blocks:

UTC 00:00 -> 03:00
UTC 10:00 -> 13:00
UTC 15:00 -> 18:00

Please refer to timeanddate.com if you would like to understand the schedule in your time zone.

Current Xcode images will continue to work as normal.

If your jobs are failing with the following error `failed to create host: Image is not supported`, please migrate to a supported version of our Xcode images.
