iOS - Does application:didFinishLaunchingWithOptions execute in main thread?

Question

I am wondering if an iOS app delegate's application:didFinishLaunchingWithOptions: method executes from within the main thread?

Ultimately I would like to know whether it is safe to put UI code in this method and if I should keep blocking code (like network interactions) out of it.

Thanks.

Answer 1

Yes, it is executed on the main thread.
