xcframework 不包含内部框架 [英] xcframework does not contain internal frameworks

问题描述

我正在尝试为我正在使用的几个第三方库创建一个 .xcframework 文件.按照 https://appspector.com/blog/xcframeworks 的说明，我

I am trying to create an .xcframework file for a few third party libraries I'm using. Following the instructions from https://appspector.com/blog/xcframeworks, I

1. 创建特定于平台的 framework 文件:

# Archive for device
xcodebuild archive -scheme TestFramework -destination="iOS" -archivePath /tmp/xcf/ios.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphoneos SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES

# Archive for simulator
xcodebuild archive -scheme TestFramework -destination="iOS Simulator" -archivePath /tmp/xcf/iossimulator.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphonesimulator SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES

此时，我已经获得了两个带有 .swiftmodule 文件的框架；一切看起来都很好.框架确实不带有 .swiftinterface 文件，但我认为没关系，因为这些是 objc 项目.那么，我

At this point, I've gotten two frameworks with .swiftmodule files; everything looks good. The frameworks do not come with .swiftinterface files, but I think that is alright as these are objc projects. Then, I

1. 将各个 framework 组合成一个单独的 xcframework 文件:

1. Combine the individual frameworks to form a single xcframework file:

# Build xcframework with two archives
xcodebuild -create-xcframework -framework /tmp/xcf/ios.xcarchive/Products/Library/Frameworks/TestFramework.framework -framework /tmp/xcf/iossimulator.xcarchive/Products/Library/Frameworks/TestFramework.framework -output /tmp/xcf/TestFramework.xcframework

这里，xcodebuild 没有失败，但它会发出一个奇怪的错误:

Here, xcodebuild doesn't fail, but it emits a curious error:

No 'swiftinterface' files found within '/Users/user/git/ReactiveObjC/output/xcf/ios.xcarchive/Products/Products/Library/TestFramework.framework/Modules/TestFramework.swiftmodule'.

至关重要的是，.xcframework 包不包含 Info.plistframework 的 或 文件夹代码>文件.显然，当我尝试在这种状态下链接到 xcframework 时，我会收到一堆缺少符号"链接器错误.

Crucially, the .xcframework package does not contain the individual frameworks or folders specified in the Info.plist file. Obviously, when I try to link to the xcframework in this state, I get a bunch of "missing symbols" linker errors.

这是为什么?我必须怎么做才能让 xcodebuild 完全创建 xcframework?

Why is this? What must I do to get xcodebuild to create the xcframework completely?

注意:目前手动创建文件夹似乎可行，但这感觉不对而且很脆弱——Apple 可以随时更改 xcodebuild 的工作方式.

NB: Manually creating the folders seems to work for now, but this feels wrong and is brittle – Apple can change the way xcodebuild works anytime.

推荐答案

原来在 xcodebuild 命令的末尾添加 BUILD_LIBRARY_FOR_DISTRIBUTION = YES 是不够的/不是努力使用所需的 swiftinterface 文件生成框架.我必须进入实际项目的设置并手动将 BUILD_LIBRARY_FOR_DISTRIBUTION 设置为 YES，例如 这个答案 建议.在我得到带有 swiftinterface 文件的框架后，我就能够使用 xcodebuild 创建 xcframework 文件而没有任何问题.

Turns out that adding BUILD_LIBRARY_FOR_DISTRIBUTION = YES to the end of the xcodebuild command was not enough / not working to produce a framework with the required swiftinterface files. I had to go in the settings for the actual project and manually set BUILD_LIBRARY_FOR_DISTRIBUTION to YES, like this answer suggests. After I got the frameworks with the swiftinterface files, I was then able to create the xcframework file using xcodebuild without any problems.
