title: App crashes with [ServicesDaemonManager] interruptionHandler is called. -[FontServicesDaemonManager connection]_block_invoke
body: <p>My App crashes randomly with this error:</p>
  <pre><code> [ServicesDaemonManager] interruptionHandler is called.
   -[FontServicesDaemonManager connection]_block_invoke
  </code></pre>
  <p>(didReceiveMemoryWarning fires before the error message)</p>
  <p>It is a bit hard to post code because of the randomness.
  I use SwiftUI (UIHostingController), @ObserverObjects, async network calls, transitions to other views, etc.</p>
  <p>It all works fine most of the time but sometimes i ran into this error.
  The memory is then increasing constantly until the app crashes.</p>
  <p>I tried to fix all possible memory leaks (to deallocate all images, [weak self], ...)
  didn't help.</p>
  <p>I'am not sure what the FontServicesDaemonManager is doing and in what way it is involved but all fonts are using the system font:</p>
  <pre><code> .font(Font.system(size: 25 , weight: .regular))
  </code></pre>
  <p>Sometimes also this error appears right after the one from obove:</p>
  <pre><code>-[UIWindow endDisablingInterfaceAutorotationAnimated:] called on &lt;UIWindow: 0x10aab11a0; frame = (0 0; 375 812); gestureRecognizers = &lt;NSArray: 0x10acb2510&gt;; layer = &lt;UIWindowLayer: 0x10aacbee0&gt;&gt; without matching -beginDisablingInterfaceAutorotation. Ignoring.
  </code></pre>
  <p>Anyone ran into similar issues or has an idea how to fix this?
  (Xcode 11.6)</p>
