Where to remove observer for NSNotification in Swift?

Where should I remove the observer for NSNotification in Swift, since viewDidUnload and dealloc() are unavailable?

Solution

  • Use below method which functions same as dealloc.

    deinit {
    // Release all resources
    // perform the deinitialization
}

    A deinitializer is called immediately before a class instance is deallocated. You write deinitializers with the deinit keyword, similar to how intializers are written with the init keyword. Deinitializers are only available on class types.
