Safety is always essential, especially when you are working in a team.
What will happen if you run the following code snippet?
You will get an “Index out of bounds” run-time error, and the application will crash. Companies never want to risk their apps crashing. Even though you are 99.99% sure that it won’t crash, checking the index before accessing the elements of a Collection is highly recommended, especially if you are not the only one working on the codebase.
You can add a handy Collection extension to your project for safe bounds check.
To use it.
Now, the application won’t crash, and “Index out of bounds” will be printed out ;)
