title: Xcode 11.2.1 confused about the minimum deployment target
body: <p>I have a library and an app in the same workspace. One is dependent on the other. When I compile I get an error saying that the library is build for iOS 11 but the apps deployment target is iOS 10.
  I change the minimum deployment target for the library. Same error.
  I change the minimum deployment target for the app. Same error.
  I clean the build folder, delete the derived data, reboot the computer. Same error.
  The minimum deployment target can be changed in two places in the project settings, either in the info tab or the build settings tab. They both seem to be in sync.
  Is there anywhere else it is stored?</p>
