ios - Swift 中的 Int 和 Int32 有什么区别？

Question

在Core Data中你可以存储Int16, Int32, Int64 但它不同于诠释。它们存在的原因是什么，如何使用它们？

Answer 1

根据Swift Documentation

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 2,147,483,647, and is large enough for many integer ranges.
