CoronaSDK may support an older version of Xcode but your MacinCloud server likely has the latest version. The default Xcode Command Line Tool path (xcode-select) is set to what is installed on the server
Change the directory
For Managed and Pay-As-You-Go users, you may overwrite the xcode-select path by setting the DEVELOPER_DIR variable:
1. After logging in, open Terminal and set DEVELOPER_DIR to the version of Xcode that is supported by CoronaSDK (In this example, 7.0.1):
> export DEVELOPER_DIR = "/Applications/Xcode7.0.1.app/Contents/Developer"
2. Run CoronaSDK through Terminal:
> /Applications/CoronaSDK/Corona\ Terminal
In this example, this will change xcode-select path to Xcode 7.0.1.
If you experience any complications when executing these steps, please contact our support staff.
