Reserved Variables in Appcircle

Here is a list of pre-defined environment variables in Appcircle.

These reserved environment variables are either predetermined by Appcircle or are set in the build configuration.

You can check how these environment variables are utilized within the related workflow step. For instance, you can set the Xcode version of a build profile through the build configuration, which will then set this value as the AC_XCODE_VERSION environment variable.

You can then use this variable in any workflow step and this variable will be assigned as the default input value of the Xcode Select workflow step. This assignment is editable, meaning that you can either choose to keep it in the same way it is configured or you can change it by specifying a value directly in the step settings or assigning a different environment variable.

For more information on the inputs of the steps and how the variables in the following steps are used, please refer to the documentation of the specific step that is available at
