title: Why can I not install more than three apps?
body: <p>I have just started learning how to make iOS apps, and am using the free personal developer account.</p>
  
  <p>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:</p>
  
  <blockquote>
    <h3>App installation failed</h3>
    
    <p>The maximum number of apps for free development profiles has been reached.</p>
  </blockquote>
  
  <p>From what I have read, each app should be signed for a week, but I've only been coding from a few days.</p>
  
  <p>How can I install more apps, or do I have to delete my existing apps from my device?</p>
