ios - Why can I not install more than three apps?

Question

I have just started learning how to make iOS apps, and am using the free personal developer account.

I have made four apps so far, but do not seem to be able to install more than three apps. Even if I have three apps installed, and go to update one of the installed apps I receive the following error message in Xcode:

App installation failed

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

From what I have read, each app should be signed for a week, but I've only been coding from a few days.

How can I install more apps, or do I have to delete my existing apps from my device?

Answer 1

Just delete the apps that you have installed using the same profile from your device. just clean the project by using the command SHIFT+Command+K ,Try to run the project again.In my case it worked .No need to pay any fee.I hope it works for you too.
