title: iOS 13 SDK deadline confusion for existing released apps
body: <p>I'm confused by Apple's latest email regarding their requirements for apps to use iOS SDK 13.</p>
  
  <p>So first there was this message March 4th:</p>
  
  <p><a href="https://developer.apple.com/news/?id=03042020b" rel="noreferrer">Submit Your iPhone Apps to the App Store</a></p>
  
  <blockquote>
    <p>Starting April 30, 2020, all iPhone apps <strong>submitted</strong> to the App Store must be built with the iOS 13 SDK or later.</p>
  </blockquote>
  
  <p>Then they send out this message on March 26th:</p>
  
  <p><a href="https://developer.apple.com/news/?id=03262020b" rel="noreferrer">Deadline for App Updates has Been Extended</a></p>
  
  <blockquote>
    <p>To accommodate developers who may need <strong>additional time to update their existing apps on the App Store</strong>, the deadline for adhering to the requirements below has been extended to June 30, 2020.</p>
    
    <ul>
    <li>Apps for iPhone or iPad <strong>must be built with the iOS 13 SDK or later</strong> and use an Xcode storyboard to provide the app’s launch screen.</li>
    </ul>
  </blockquote>
  
  <p>I have an app that I have no need to update right now (it was built with iOS 12 SDK).</p>
  
  <p>So what does that last message mean? Do I need to re-build and re-submit just to meet this requirement in order to keep my app on the App Store? Or do they only mean this is required for new app updates submitted?</p>
