title: XCode trying to locate service account file
body: <p>When I try to build my Project in XCode, I get the following dialog box:</p>
  
  <p><a href="https://i.stack.imgur.com/NVXuh.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NVXuh.png" alt="dialog"></a>
  It asks for a <code>service account file</code> which I am not sure of.
  If I cancel it, I get the following error in <code>upload-symbol-util.bash</code> file:</p>
  
  <pre><code># If the token will expire in the next sixty seconds (or already
  # has), reload it.
  if ! fcr_verify_tok_plist; then
      xcdebug "Token is invalid. Refreshing..."
      if ! fcr_verify_svc_plist; then
          xcdebug "Service account information is invalid. Requesting reload..."
          if [[ "$SERVICE_ACCOUNT_FILE" &amp;&amp; -f "$SERVICE_ACCOUNT_FILE" ]]; then
              xcdebug "Using $SERVICE_ACCOUNT_FILE for credentials."
          else
              SERVICE_ACCOUNT_FILE="$(/usr/bin/osascript -e 'the POSIX path of (choose file with prompt "Where is the service account file?" of type "public.json")' 2&gt;/dev/null)"
          fi
  
          /usr/libexec/PlistBuddy "$SVC_PLIST" \
              -c "Add :version integer 1"
  
          if [[ "$SERVICE_ACCOUNT_FILE" &amp;&amp; -f "$SERVICE_ACCOUNT_FILE" ]]; then
              /usr/bin/plutil -replace "$APP_KEY" -json "$(/bin/cat "$SERVICE_ACCOUNT_FILE")" "$SVC_PLIST" || return 2
  
              if fcr_verify_svc_plist; then
                  xcdebug "Installed service account file into $SVC_PLIST."
              else
                  /usr/libexec/PlistBuddy "$SVC_PLIST" -c "Delete $APP_KEY" &gt;/dev/null 2&gt;&amp;1
                  xcerror "Unable to parse service account file."
                  return 2
              fi
          else
              xcerror "User cancelled symbol uploading." // Getting Error here
              return 1
          fi
      fi

  <p>Please tell what is a <code>Service Account file</code> and where do I find it?</p>
