Int
In most cases,you don’t need to pick a specific size of integer to use in your code. Swift provides an additional integer type,Int,which has the same size as the current platform’s native word size:
On a 32-bit platform,Int is the same size as Int32.
On a 64-bit platform,Int is the same size as Int64.
Unless you need to work with a specific size of integer,always use Int for integer values in your code. This aids code consistency and interoperability. Even on 32-bit platforms,Int can store any value between -2,147,483,648 and 2,647,and is large enough for many integer ranges.
