X不是Y的成员类型

I'm having staring issues with Module name spacing in a swift project.

我在swift项目中遇到了模块名称间距的问题。

I've tried this in a new project and everything works fine:

我在一个新项目中试过这个,一切正常:

I have 2 modules with which contain the same class name and i'm able to reference the class from Module.Class no problem.

我有2个模块,其中包含相同的类名,我可以从Module.Class引用该类没问题。

I have an existing swift project and I'm unable to get this working. I keep getting the error

我有一个现有的快速项目,我无法让这个工作。我一直在收到错误

So as you can see if I don't try to Module-Scope the class everything works fine.

因此,你可以看到我是否不尝试Module-Scope类,一切正常。

(And yes i've tried with and with out the .Type addition).

(是的,我已经尝试过使用.Type添加)。

So I'm assuming there is something off in my compiler setting. The only other thing I can think of is that my LocationMessage class is defined not in the main DataManager "class" file but rather in a different file.

所以我假设我的编译器设置中有一些关闭。我唯一能想到的是我的LocationMessage类不是在主DataManager“类”文件中定义的,而是在不同的文件中定义的。

But I really can't make heads or tails of whats going on. Any suggestions?

但我真的无法做出正面或反面的事情。有什么建议么?

Project Structure

Framework: DataManager

DataManager.swift
LocationMessages.swift

Framework: ReferenceTest

File.swift

So my issue is that in File.swift I'm trying to reference a class defined in LocationMessages.swift inside the DataManager.framework The class IS public

所以我的问题是在File.swift中我试图引用在DataManager.framework里面的LocationMessages.swift中定义的类。

@objc(DMLocationMessage)
final public class LocationMessage : ParsedMessage {

You likely have a class/struct/enum DataManager anywhere in your code which hides the DataManager module. The error states that it cannot find LocationManager in type DataManager where it should read module instead.

您可能在代码中的任何位置都有一个类/结构/枚举DataManager,它隐藏了DataManager模块。该错误表明它无法在DataManager类型中找到LocationManager,而应该在其中读取模块。

Your app modules should be designed in a way so that you never need to explicitly use the module's name except for the import statement. So just use LocationMessage.Type directly without stating the module.

您的应用程序模块应该以某种方式设计,以便除了import语句之外,您永远不需要显式使用模块的名称。所以直接使用LocationMessage.Type而不说明模块。

This is one reason all our app's modules are prefixed with an X, e.g. XDataManager. This avoids conflicts with Apple's modules, external modules (like from CocoaPods) and with types (like in your case).
The X also makes it obvious that these modules are part of the app itself and not some third-party frameworks.

这是我们所有应用程序模块都以X为前缀的一个原因,例如: XDataManager。这避免了与Apple的模块,外部模块(如来自CocoaPods)和类型(如您的情况)的冲突。 X也明显表明这些模块是应用程序本身的一部分,而不是某些第三方框架。

There is also this bug in swift compiler: SR-631 Extensions in different files do not recognize each other

swift编译器中也存在这个错误:不同文件中的SR-631扩展不能互相识别

The result (success/failure) of the compilation depends on the order of files in Build Phase > Compile Sources setting.

编译的结果(成功/失败)取决于“构建阶段”>“编译源”设置中的文件顺序。

I had exactly the same error message: X is not a member type of Y. Solved it by rearranging compilation sources.

我有完全相同的错误消息:X不是Y的成员类型。通过重新安排编译源解决它。
