现在是不是 for-in 只能这么写了 for i in 0...3
一开始似乎是 0..3 和 0...3
后来改成 0...3 和似乎是 0...<3
现在只有 0...3 了吗

应该是：
1...3（三个点） 1..<3（两个点） |

是有变化，而且我发现iBooks的书要是有更新，本地是不会有提示的，需要手动再下一次。
在Swift Programming language中搜索Range operators就能找到最新的。 1...3 是 Closed Range Operator => 1 2 3 1..<3 是 Half-Open Range Operator => 1 2 https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/BasicOperators.html |
