I was working on my application and i started out with a really bad name. So i decided to change it. I did that like this.
I recently got this error under different circumstances. Running Ionic, updating my ios platform from 3.8.0 to 4.0.1 I discovered this error.
I had to disable bitcode in my app.
To do this, click your top level app icon in the file structure. In the main window, click the header build settings. In the search bar, type bit (or bitcode) and you should see enable bit code beneath
I had disabled it before, but I'm guessing that updating the ios platform enables bitcode so it needed to be disabled again.
