Xcode 6/Beta 4:不支持对框架目标使用桥接头 [英] Xcode 6 / Beta 4: using bridging headers with framework targets is unsupported
问题描述
我刚刚升级到 Xcode 6 Beta 4 并且有一个我为 Beta 2 中的实时视图创建的框架.由于另一个 swift bug，我需要使用一些 Obj-C 代码.升级时，我收到以下错误:
I just upgraded to Xcode 6 Beta 4 and have a framework that I created for Live Views in Beta 2. Due to another swift bug, I needed to use some Obj-C code. When upgrading though, I get the following error:
错误:不支持对框架目标使用桥接头
error: using bridging headers with framework targets is unsupported
我在发行说明中没有看到任何内容，也没有找到任何其他迁移路径.有没有其他人看到过这个并找到了解决方案?
I have not seen anything in the release notes, or found any other migration path. Has anyone else seen this and arrived at a solution?
我意识到 Beta 3 消除了对实时视图框架的需求，但在我的情况下，如果我可以让它工作，这是有道理的.我可以将它删除作为后备，但如果它们在 Beta 4 中没有完全损坏，我更愿意使用框架.
I realize that Beta 3 eliminated the need for frameworks for live views, but it makes sense in my case if I can get it to work. I can remove it though as a fallback, but would prefer to use a framework if they are not totally broken in Beta 4.
推荐答案
正如错误所述，框架中不允许使用桥接头.混合 &匹配 苹果文档对此的提示.正如他们所说，你需要在你的伞头文件中，导入你想要暴露给 Swift 的每个 Objective-C 头文件".
As the error states, bridging headers are not allowed in Frameworks. The Importing Code from Within the Same Framework Target section of the Mix & Match apple documentation hints at this. As they say, you need to "In your umbrella header file, import every Objective-C header you want to expose to Swift".
但是，我发现您可能还需要公开这些特定的标头.这个答案回顾了为什么以及如何做到这一点:Swift 编译器错误:框架模块内的非模块化头文件".
However, I discovered that you may also need to make those specific headers public as well. This answer reviews why and how to do that: Swift compiler error: "non-modular header inside framework module".
所以，这样做:
- 删除您的桥接头文件.
- 在框架的构建设置中删除对桥接头文件的引用
- 将必要的标题添加到您的保护伞文件 ([ProductName].h)
- 在框架的构建阶段"的标题"部分公开包含的文件.
- 清理和重建.
注意:伞形头文件"是一个文件(名为 [ProductName].h)，通常代表框架的所有公共头文件.它通常只是框架中包含的其他标头的#import 语句列表.在Xcode中，如果你打开UIKit.h，你会看到一个很好的伞形文件示例.
Note: The "umbrella header file" is a file (named [ProductName].h) that generally represents all public headers of a framework. It is usually just a list of #import statements to other headers contained in the framework. In Xcode, if you open UIKit.h, you will see a good example of an umbrella file.
