The maximum number of apps for free development profiles has been reached

My question is an updated version of this one and I can't seem to find the way forward in this new version of XCode. I am new to Unity and XCode and had no idea there were a limited number of apps allotted to a personal development profile. Every time I screwed up a project trying to do this tutorial I often struggled to fix it or made it worse (version and platform clash issues) so I started a new project without any idea it would count against some app count on my profile. I had no idea these unfinished doodles were considered apps. As I said, I'm a total newb in this realm! Now I've used all my apps and still don't have anything that works. How do I fix this? Thanks for your help.

This is the error I get from Xcode: The maximum number of apps for free development profiles has been reached.

Xcode version 11.4 (11E146)

The easiest way to solve this is delete these unfinished apps from your devices. Just delete them like you would any other app - directly on the phone.

You can also use the "Devices & Simulators" window in Xcode to delete them. If you have a lot, it is perhaps a bit faster.

If you have deleted the apps, but still get the error, then you need to remove the profiles themselves also. You can do that from the same "Devices & Simulators" window by right-clicking on the name of your iOS device, selecting "View Provisioning Profiles" and then removing them.

You can also do that on the device in Settings > General > Profile. Choose each no longer used profile and then "Remove".
