The iOS Deployment Target on the Project page is the default for all targets in the project. The iOS Deployment Target on each project is an optional project-level override.
To set a target to inherit from the project, you can't use the "General → Deployment Info" section. Instead, go to "Build Settings → Deployment", and for "iOS Deployment Target" choose "Other..." and enter $(inherited).
