Hey guys,

I created a free developer account at Apple (without developer enrollment because it was paid), but cannot run the preview on xcode, I get the following message:

[https://gyazo.com/4761e23cdd5a5e94b518271a4e6d7661](https://gyazo.com/4761e23cdd5a5e94b518271a4e6d7661)

“Failed to create provisioning profile.  
The app ID “com.apps.hikr” cannot be registered to your development team. Change your bundle identifier to a unique string to try again.”

Any tips on what I need to do?

thanks!

Hi Alexandre,

you shouldn’t need an account with developer enrolment just to preview on iOS. As the error message says, you should `Change your bundle identifier to a unique string to try again.` - so open your `.unoproj` file, change the [bundle identifier](https://www.fusetools.com/docs/basics/uno-projects#rootnamespace) to something else, and try running the preview again.

Hope this helps!

No, those that you’ve shown generally seem to not cause any trouble with the app.
