添加Swift文件后构建Swift Cocoa Touch Framework时出错： <unknown> ：0：错误：无法构建Objective-C模块

Question

I have a problem creating a Swift Cocoa Touch Framework. As soon as I add my first .swift file, clean, then build I get a build error:

<unknown>:0: error: could not build Objective-C module 'MyTextFramework'

This is easily reproducible from scratch in just a few steps using Xcode 6.1.1

• Create new Cocoa Touch Framework using Swift Language
• Add an iOS swift file
• Build - OK
• Clean - OK
• Build - ERROR
• From here on the project will not build unless I delete the swift file.

I've tried the typical Xcode magic such as deleting derived data, restarting Xcode, etc.

---

Steps detailed below with screenshots:

File > New > Project > iOS Framework & Library > Cocoa Touch Framework

Product Name: MyTextFramework

Language: Swift

I now have a bare bones Cocoa Touch Framework.

Add an iOS Swift file named FooBaz.swift

Add a class that extends NSObject and an init function.

The target still builds fine at this point.

Cmd-K to clean the project

Cmd-B to build again... BAM

Answer 1

如果您不打算使用Objective-C中的Swift框架，最简单的解决方案是摆脱MyTextFramework.h

Answer 2

As Georg Tuparev answered, I just need to remove MyTextFramework.h and it builds fine. However, this prevents using my framework in Obj-C code.

Is it even possible to build a framework containing Swift code that can be used in both Swift AND Obj-C? If it is technically possible, then it seems this issue with Xcode would prevent anyone from actually doing it. Does anyone have any comments or solutions for this scenario?
