title: React Native Expo iOS app - trying to modify info.plist
body: <p>I have a React Native app set up in Expo.</p>
  
  <p><strong>I need to modify the info.plist</strong>, but am having problems doing so.</p>
  
  <p>First, I can't find info.plist anywhere.
  Based on the <a href="https://docs.expo.io/versions/latest/workflow/configuration/" rel="nofollow noreferrer">Expo docs</a> and this other <a href="https://stackoverflow.com/questions/48157185/info-plist-file-for-react-native-ios-app-using-expo-sdk">SO question</a>, the workaround is to add an "infoPlist" key into my app.json file. I have done so, and it looks like this:</p>
  
  <pre><code>"infoPlist": {
        "NSAppTransportSecurity": {
          "blah.s3.amazonaws.com": {
            "NSExceptionAllowsInsecureHTTPLoads": true,
            "NSRequiresCertificateTransparency": false,
            "NSIncludesSubdomains": true
          }
        }
      }
  </code></pre>
  
  <p>However when I attempt to compile the app (either by running "expo start" or "expo publish") I get the following error:</p>
  
  <p>Error: Problem validating fields in app.json. See <a href="https://docs.expo.io/versions/v30.0.0/guides/configuration.html" rel="nofollow noreferrer">https://docs.expo.io/versions/v30.0.0/guides/configuration.html</a>
  Should NOT have additional property 'infoPlist'.</p>
  
  <p>Any ideas on how I can get around this?</p>
