MOB-658: dyld crash on launch when apps are built in Xcode versions earlier than Xcode 12.5

When running SDK v7.0.0 on Xcode versions earlier than Xcode 12.5, you will get an error when running the app:

This seems to be an issue in the Xcode 12.5 toolchain, which is being triggered by Starscream (one of our dependencies). We are not the only binary framework experiencing this issue.

You should either upgrade to Xcode 12.5, or upgrade to SDK v7.0.1 or newer which is built against Xcode 12.4 and does not exhibit this issue.

💡 If you have any additional insights to provide regarding the above issues, please contact support, referencing the MOB number.
