How to know the version of an iOS binary framework

Either check the Info.plist file included in the framework, or use PlistBuddy.

The PlistBuddy way

PlistBuddy is a built-in command line tool in macOS for .plist editing purposes.

Use the following command to display the Bundle Short Version of StuffManager.framework for instance:

/usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "StuffManager.framework/Info.plist"

The output should be similar to:

6.31.0
