title: What is a "development-signed version" of an iOS app? How do I run a development-signed version of my app?
body: <p>I am trying to test in-app purchases on an iOS device. At <a href="https://help.apple.com/app-store-connect/#/dev8b997bee1" rel="nofollow noreferrer">Create a sandbox tester account</a> it says: </p>
  
  <blockquote>
    <p>To connect to your development servers and the test environment for the App Store, run a development-signed version of your app and sign in using a sandbox tester account. </p>
  </blockquote>
  
  <p>The problem is, I don't know what a "devepment-signed version" is, or how to run one.</p>
  
  <p>In Xcode I have one app target, and under "Signing &amp; Capabilities", "All", "Debug" and "Release" have "Automatically manage signing" checked. I cannot find a way to run a "development-signed" version and am not having luck figuring this out by Googling. Does this have to be a physical device, or can it be a simulator?</p>
