Namespaces and modules in the Swift language
提问by rhummelmose
I've been experimenting with Swift on my way home from WWDC. One of the most compelling new features of Swift, in my opinion, was namespacing. I haven't managed to get it to work as I expected it should though. Please see the attached screenshot and let me know if you have an idea of what I'm doing wrong.
我在从 WWDC 回家的路上一直在试验 Swift。在我看来，Swift 最引人注目的新特性之一是命名空间。我还没有设法让它像我预期的那样工作。请查看随附的屏幕截图，如果您知道我做错了什么，请告诉我。
EDIT: I have of course tried to remove the import statement.
编辑：我当然尝试删除导入语句。

I am sorry, if I search for "namespace" or "namespacing" in the Swift-eBook there are no results. Maybe you can give me a link to an additional resource?
抱歉，如果我在 Swift-eBook 中搜索“命名空间”或“命名空间”，没有结果。也许你可以给我一个额外资源的链接？
I would solve your problem simply with a structand staticfunctions.
我会用一个struct和static函数来解决你的问题。
ClassA
A类
struct ClassA {
static func localize() {
println("Localized String")
}
}
ClassB
B级
You can drop the import and execute the ClassA-function as follows:
您可以删除导入并执行 ClassA 函数，如下所示：
ClassA.localize()
The second way
第二种方式
In your case you can also just make an extension of String like so:
在您的情况下，您也可以像这样对 String 进行扩展：
extension String {
func localize() -> String {
return self+"-localized"
}
}
println("Test".localize()) // prints "Test-localized"
