title: Firebase look in child(uid) for child(currentUid) swift
body: <p>I want to look into a child to look for another child. I want to find my current Uid in someone elses uid. How do I do that?</p>
  <pre><code>guard let currentUid = Auth.auth.currentUser?.uid else { return }
  guard let (this is missing) = ... else { return } 
  
  Database.database().reference().child(&quot;users-following&quot;).child(&quot; ... &quot;).child(currentUid)
  </code></pre>
  <p>The &quot;this is missing&quot; and child(&quot;...&quot;) indicate, where I am not getting anywhere. Can someone help me?
  I want to look in this child(&quot;…&quot;) to check and see if my currentUid is in that list.</p>
  <p>______ UPDATE _______</p>
  <pre><code>&quot;user-followers : {
    &quot;YsBqvPlRGMfx...&quot; : {
      &quot;iFjaXB7lI...&quot; : 1 
    }
  },
  </code></pre>
  <p>iFjaXB... is the user, that deletes the account. All his data is being deleted as it's supposed to. But the id stays within the YsBq child in the &quot;user-followers&quot;. So, I want to delete the child &quot;iFjaXB&quot; in the child of &quot;YsBq&quot;. How do I do this?</p>
