Steps to Reproduce

1. Set

    [FBSDKAppEvents logEvent:FBSDKAppEventNameViewedContent parameters:@{FBSDKAppEventParameterNameContentType: contentType}];

2. Run the application for the first time
3. Get crash
4. Run the application a second time - no crash

Code Samples & Details

+ (FBSDKAppEvents *)singleton
{
  static dispatch_once_t onceToken;
  static FBSDKAppEvents *shared = nil;
  dispatch_once(&onceToken, ^{ // Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
    shared = [[self alloc] init]; 
  });
  return shared;
}

You will need to initialize the SDK before calling any methods. This is in the documentation and the release notes for v9. Is this the reason for the crash? If not please update the issue with reproducible sample. Thanks!

Thank! I have updated the FB SDK from "5.15.1" to "9.0.1" and am getting a crash.
Need to add to AppDelegate

ApplicationDelegate.shared.application(application,
                                       didFinishLaunchingWithOptions: launchOptions)

and

ApplicationDelegate.shared.application(app,
                                       open: url,
                                       sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
                                       annotation: options[UIApplication.OpenURLOptionsKey.annotation])
