Help migrating from v1 to v2 Objective C

I have tried - but the weird thing is once it hands back control to my application, it has disconnected from the debugger.

So I tried the following to force it to log something, but it doesn't.

- (void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    self.restClient = [DropboxClientsManager authorizedClient];

    if (!networkLost) {
        [self checkForBackups];
    }
}
- (void) checkForBackups {
    //Determine if backup exists
    NSLog(@"trying to check for backups");
    
    if(self.restClient != nil ) {
        //_loadingView = [LoadingView loadingViewInView:[self.view.window.subviews objectAtIndex:0] withMessage:@"Checking for existing backup...."];        
        NSLog(@"You are linked: %@", self.restClient);
        
       
        [[self.restClient.filesRoutes getMetadata:@""]response:^(DBFILESMetadata * _Nullable result, DBFILESGetMetadataError * _Nullable routeError, DBRequestError * _Nullable error) {
            if(result != nil){
            }
            if(error != nil || routeError != nil){
                 NSLog(@"Error: %@", error);
                 NSLog(@"Error: %@", routeError);
            }
    
        }];
        
    }

}

So while I am in the same instance - when I open this after linking, it crashes.  I have placed log statements - but they aren't fired.  It's just odd..
