Build operations are disabled:'project.xcworkspace' has changed and is reloading

Question

I got this message, which is as follows.

Then again I tried to rebuild it, which lead me to this alert message.

Now if I select Xcode Version, it starts throwing error which is related to the dependency of the external libraries I have added. Any suggestion.

Answer 1

I have the exact same issue with Xcode 7.3.

Restarting the IDE helps.

Answer 2

I had similar issue with Xcode 9.3 and solution mentioned by @sssliver didn’t worked.

Below is solution that worked :

1. Quit Xcode (cmd + Q) and reopen project
2. Delete derived data content.
3. Clean project (cmd + shift + K)
4. Build project (cmd + B)
