Build operations are disabled: "project.xcworkspace" has changed and restarts

Question

I received this message, which is as follows.

Then I tried to rebuild it, which led me to this warning message.

Now, if I select the Xcode Version, it will start throwing an error related to the dependency of the external libraries that I added. Any suggestion.

Answer 1

I have the same problem with Xcode 7.3.

Restarting the IDE helps.
