In a recent project I started with a name for my iOS application and later decided to change it. I tried to rename it as described in the Apple Technical Q&A QA1625 without success. For some reason the simulators targets were gone and the iOS device target was also gone.
After several attempts i found the problem. My project was embedded in an Xcode workspace. All I had to do was open the project (not the workspace) and do the rename from there. After that, I had to relink the project in the workspace. And that was it.
