Classes, structures, and enumerations can define subscripts, which are shortcuts for accessing the member elements of a collection, list, or sequence. You use subscripts to set and retrieve values by index without needing separate methods for setting and retrieval. For example, you access elements in an
Arrayinstance assomeArray[index]and elements in aDictionaryinstance assomeDictionary[key].You can define multiple subscripts for a single type, and the appropriate subscript overload to use is selected based on the type of index value you pass to the subscript. Subscripts are not limited to a single dimension, and you can define subscripts with multiple input parameters to suit your custom type’s needs.

Swift – Use generics [T] with closures
Let’s make an example to understand better the scope of this tutorial.
You want to:
- increment all numbers in array by 1
- double all numbers in array
- check if the numbers in array are even or odd
- multiply all numbers in array
- more and more…
How many functions should you create to do this?
XCode – Add a file in project at build time
Imagine that you need to add a file in your XCode project the first time that you build the app.
For instance, you have a configuration file, in Swift, that you want to compile and embed in your app (instead of using a PLIST file that is in CLEAR…) during the build phase and of course use in your project.
