Answer 1

Also to add,

If someone is looking for a way to run sepcifically the Geolocation plugin as a background thread with iOS Cordova there is a fix on GitHub.

It removes the Xcode output warning: "THREAD WARNING: ['Geolocation'] took 'X' ms. Plugin should use a background thread."

Download the plugin from here: https://github.com/guillaumedev/cordova-plugin-geolocation

Heres whats changed (runInBackground added): https://github.com/guillaumedev/cordova-plugin-geolocation/commit/8fbceca845441f4f421548f243d2f05573d11225

Answer 2

As per this. solved my warning issue

I found warning can be ignored .But this can be solved by adding background thread using this loop:(In CDVLogger.m)

 [self.commandDelegate runInBackground:^{

    //add your code here
 }

Now this looks as below for console warning:

- (void)logLevel:(CDVInvokedUrlCommand*)command
 {
   [self.commandDelegate runInBackground:^{
   id level = [command argumentAtIndex:0];
   id message = [command argumentAtIndex:1];

  if ([level isEqualToString:@"LOG"]) {
    NSLog(@"%@", message);
  } else {
      NSLog(@"%@: %@", level, message);
   }
 }];
}
