title: Can 2 same bundle ID cause any conflict?
body: <p>I read from <a href="https://developer.apple.com/library/ios/documentation/General/Conceptual/DevPedia-CocoaCore/AppID.html" rel="nofollow">Cocoa Core Competencies</a>
  that </p>
  
  <blockquote>
    <p>An App ID is a two-part string used to identify one or more apps from
    a single development team. The string consists of a Team ID and a
    bundle ID search string, with a period (.) separating the two parts.</p>
  </blockquote>
  
  <p>However it also says that,</p>
  
  <blockquote>
    <p>The bundle ID is a unique identifier that identifies a single app and
    cannot be used by other teams.</p>
  </blockquote>
  
  <p>I see that we can't register an App ID in the Developer account portal with same bundle ID of an app that is on the appstore. </p>
  
  <blockquote>
    <p>An App ID with Identifier 'com.example.myapp' is not available. Please enter a different string.</p>
  </blockquote>
  
  <p>So I don't know if 2 apps from 2 developers can have same bundle ID (like com.example.MyApp), and if this causes any conflicts?</p>
  
  <ul>
  <li>Can these 2 apps be installed on the device?</li>
  <li>Can these 2 apps be allowed on the app store?</li>
  <li>How does Push Notification work with these 2 apps ?</li>
  <li>I see that many services like Fabric Crashlytics, Urban Airship, Google App Invites, ... depends on the Bundle ID to differentiate among apps.</li>
  </ul>
