Mastering Swift 2 Programming (Video 34)

This video tutorial covers resolving race conditions in threading by using asynchronous methods and completion handlers in Swift. It explains the difference between synchronous and asynchronous methods, and how to implement closures as completion handlers. The tutorial also demonstrates using Alamo Fire for server communication in a game application, reviewing code to identify issues, and adding completion handlers to improve game logic. The video concludes with finalizing and testing the application.

What is the primary difference between asynchronous and synchronous methods?

• Synchronous methods are faster than asynchronous methods.

• Synchronous methods use completion handlers.

• Asynchronous methods use completion handlers instead of returning values immediately.

• Asynchronous methods return values immediately.

What is the purpose of using Alamo Fire in the Game of Life application?

• To add new levels to the game.

• To improve the game's performance.

• To call out to a server for sending and receiving messages.

• To enhance the game's graphics.

Why is it important to avoid strong reference cycles in closures?

• To prevent memory leaks.

• To make the code more readable.

• To ensure the application runs on all devices.

• To increase the speed of the application.

What change was made to the 'evolve' method in the Game of Life application?

• The method was renamed to 'startGame'.

• A new parameter was added to increase speed.

• The method was removed to simplify the code.

• A completion handler was added to determine when the game ends.

What triggers the end of the game in the modified Game of Life application?

• When the player decides to quit.

• When the player reaches a new level.

• When the live cells count drops below a certain threshold.

• When the timer runs out.
