Is it a known thing that Bundle IDs are case insensitive? In the sense that once you register:
com.yourname.AppName
… you can no longer change it to lowercase:
com.yourname.appname
I ask, because I got this error in Xcode:
Failed to register bundle identifier. The app identifier [Bundle ID] cannot be registered to your development team because it is not available. Change your bundle identifier to a unique string to try again.
Even though I know that name hasn't been registered by someone else.
