ios Xcode 10 错误：为“app”和“appex”生成多个命令

Xcode 10 Error: Multiple commands produce for 'app' and 'appex'

提问by Norbert

I got the recently discussed "Xcode 10 Error: Multiple commands produce..." error, but for the resulting app and appex file of my project. Does anyone have an idea what this means. My project has one app and two extensions (only one is part of the error).

我得到了最近讨论的“Xcode 10 错误：多个命令产生...”错误，但对于我项目的结果应用程序和 appex 文件。有谁知道这是什么意思。我的项目有一个应用程序和两个扩展程序（只有一个是错误的一部分）。

I know I can go back to the legacy build system, but I would prefer using the new and faster build system. Thank you for any help.

我知道我可以回到旧的构建系统，但我更喜欢使用新的和更快的构建系统。感谢您的任何帮助。

Solved my problem by updating Cocoapods from 1.4.0 to 1.5.3

通过将 Cocoapods 从 1.4.0 更新到 1.5.3 解决了我的问题

In case someone is still struggling with this after updating cocoapods and reinstalling pods:

如果有人在更新 cocoapods 并重新安装 pod 后仍然在为此苦苦挣扎：

1. Open Build Phases of the target which gives you problems
2. Open Copy Pods Resources phase.
3. Make sure the Output Files is empty. In my case I had a strange entry ${TARGET_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}. I removed it and the build was successful

1. 目标的开放构建阶段会给你带来问题
2. 打开复制 Pod 资源阶段。
3. 确保输出文件为空。就我而言，我有一个奇怪的条目${TARGET_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}。我删除了它并且构建成功

I was able to fix it by opening the Runner workspace project in Xcode 10. Then navigate to File, Workspace Settings and change the build system to Legacy Build System.

我可以通过在 Xcode 10 中打开 Runner 工作区项目来修复它。然后导航到 File、Workspace Settings 并将构建系统更改为 Legacy Build System。

My Cocoapod version was already 1.5.3(latest). Just running "pod install" (or "pod install --no-repo-update" if you don't want to update existing pods) solved it for me.

我的 Cocoapod 版本已经是 1.5.3（最新）了。只需运行“pod install”（或“pod install --no-repo-update”，如果你不想更新现有的pods）就为我解决了这个问题。

set "Build System" to "Legacy Build System" in "Shared Workspace Settings" which you can find in "File --> Workspace Settings"

在“共享工作区设置”中将“构建系统”设置为“传统构建系统”，您可以在“文件 --> 工作区设置”中找到该设置

My workaround:

我的解决方法：

1. Check your pod version pod --version. Update Coacoapods to latest version - v1.5.3 if it's not, by running sudo gem install cocoapods

2. Update all your pods by running pod update

3. Remove duplicate info.plistfile from Target>Build Phases>Copy Bundle Resourcesif any.

1. 检查您的 pod 版本pod --version。将 Coacoapods 更新到最新版本 - 如果不是 v1.5.3，请运行sudo gem install cocoapods

2. 通过运行更新所有 Pod pod update

3. 如果有的话，删除重复的info.plist文件Target>Build Phases>Copy Bundle Resources。

Works form me:

作品形式我：

• Update Cocoapods
• Delete pod file (Don't forgot to copy the contents some where else, so you can restore it)
• Delete workspace project file
• Delete lock pod file
• Delete pod directory
• Close the Xcode
• Initialise pod
• Install pod
• Open the workspace project.

• 更新 Cocoapods
• 删除 pod 文件（不要忘记将内容复制到其他地方，以便您可以恢复它）
• 删除工作区项目文件
• 删除锁舱文件
• 删除pod目录
• 关闭 Xcode
• 初始化 pod
• 安装吊舱
• 打开工作区项目。

One of a possible issues causing the "Multiple commands produce" error may be several targets with conflicting module name. In my case I had a main application target and a notification service extension target with the same Product Module Name, so Xcode was trying to create two ModuleName.swiftmodule files, two ModuleName.swiftdoc files etc. Changing notification service extension module name fixed the problem.

导致“多个命令产生”错误的可能问题之一可能是具有冲突模块名称的多个目标。在我的例子中，我有一个主应用程序目标和一个通知服务扩展目标具有相同的Product Module Name，所以 Xcode 试图创建两个 ModuleName.swiftmodule 文件，两个 ModuleName.swiftdoc 文件等。更改通知服务扩展模块名称修复了问题.

The key was to do pod deintegrateand rm *.workspacefile !

关键是做pod deintegrate和rm *.workspace归档！

You might have ran into this CocoaPods issuewhich is caused by this Xcode issue

您可能遇到了由这个Xcode 问题引起的CocoaPods问题

This replymight help you, it suggest to specify the subspecs explicitly in your Podfile.

此回复可能对您有所帮助，它建议在您的 Podfile 中明确指定子规范。

For example use pod 'SDWebImage/Core'instead of pod 'SDWebImage'

例如使用pod 'SDWebImage/Core'代替pod 'SDWebImage'

Apparently, this causes the build product path to always contain the subspec name which might fix the issue.

显然，这会导致构建产品路径始终包含可能解决问题的子规范名称。
