title: Universal linking not working on iOS in Flutter due to XCode
body: <h1>What I have:</h1>
  <p>I have a flutter app and I am using the unilink plugin to forward deeplinks.
  On Android, everthing works as intended, but not on iOS.</p>
  <p>This is my iOS json:</p>
  <p><a href="http://connector.horizonpedia.com/.well-known/apple-app-site-association" rel="nofollow noreferrer">http://connector.horizonpedia.com/.well-known/apple-app-site-association</a></p>
  <p>and these are my XCode .entitlement Settings:</p>
  <p><a href="https://i.stack.imgur.com/3SdB8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3SdB8.png" alt="enter image description here" /></a></p>
  <p>I also checked my URL params in Info.plist:</p>
  <p><a href="https://i.stack.imgur.com/VaeCQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VaeCQ.png" alt="enter image description here" /></a></p>
  <p>Json passed the test on <a href="https://branch.io/resources/aasa-validator/" rel="nofollow noreferrer">https://branch.io/resources/aasa-validator/</a></p>
  <p>I am pretty sure I have done everything correctly except ticking this box</p>
  <h1>Problem:</h1>
  <p>as you can see, the target runner checkbox is unticked and I can't tick it by clicking on it.</p>
  <p>any ideas how to solve this?</p>
