swift - 溢出除法运算符 '&/' 无法识别

Question

以下 playground 会导致错误:

1 &/ 0 

错误:

Operator is not known binary operator
Use of unresolved identifier '&/'

Documentation说它应该返回 0

运行 xCode:版本 6.3.1 (6D1002)

有什么想法吗？

Answer 1

&/ 和 &% 在 Xcode 6.3 中被移除。

根据 release notes :

Unlike the &+, &-, and &* operators, these operators did not provide two’s-complement arithmetic behavior; they provided special case behavior for division, remainder by zero, and Int.min/-1. These tests should be written explicitly in the code as comparisons if needed.
