Failed to load schema due to error

Question

Something happened with a small test project I'm working on. I cannot build, run, test or clean it. When I select an item Productin the Xcode menu, the corresponding options are inactive. If I try to test it or change the circuit, I see the following:

Xcode 6 -

Xcode 5 -

What is it? Have you ever encountered such a problem?

Answer 1

I had a similar problem. Just add a new circuit and remove the error with the error.

Answer 2

This error usually occurs when your .xcscheme file conflicts. Expand the conflict and restart Xcode.
