title: `FIRApp configure` is crashing my app, how do I fix it?
body: <p>I have this line in my <code>AppDelegate.m</code> file: <code>[FIRApp configure];</code></p>
  <p>more precisely it looks like this:</p>
  <pre><code>@implementation AppDelegate
  
  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
    [FIRApp configure];
  </code></pre>
  <p>at the top: <code>#import &lt;Firebase.h&gt;</code></p>
  <p>it's definitely breaking here as when I comment it out, rebuild my app, distribute to my device it works fine. it also works fine both ways on the simluator (annoyingly meaning I have to rebuild and distribute every time to test a fix)</p>
  <p>I saw the error happening here: <a href="https://github.com/firebase/firebase-ios-sdk/issues/340" rel="nofollow noreferrer">https://github.com/firebase/firebase-ios-sdk/issues/340</a></p>
  <p>I've tried the fix here but to no avail. I have my <code>GoogleService-Info.plist</code> in xcode living under my files. I added it by right clicking and clicking &quot;Add file to...&quot;</p>
  <p>this file is NOT showing in vs code under my <code>/ios</code> app though. is that correct?</p>
  <p>how do I fix this now? causing a lot of pain</p>
