swift - swift 中数组的 debugDescription 和 description 方法有什么区别？

Question

Swift 文档说

debugDescription = A textual representation of self, suitable for debugging
description = A textual representation of self

在 Playground 上，我得到的两个调用的输出是一样的

anArray.debugDescription // "[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]"
anArray.description // "[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]"

两者之间的实际区别是什么？

Answer 1

From Apple documentation:

an object's debug description is the same as its description. However, you can override debugDescription if you want to decouple these; many Cocoa objects do this.

所以基本上，除非您向 debugDescription 添加任何额外的功能，否则它将与 description 相同。
