在Xcode 9中运行代码正常,但在Xcode 10中有一个错误。


当前回答

Product Name的重复也可能导致同样的问题,特别是当您在单个工作空间中创建多个扩展目标时。

确保你也检查产品模块名称根据@Lirik的答案。

其他回答

在开始之前,请注意我的项目使用Carthage作为依赖管理器。

这里没有一个现有的答案能解决我的问题。为我解决这个问题的方法如下。

First, I noticed that the build error pointed out one framework in particular. Next I filtered App Target > Build Phases for that framework. I noticed that that framework was present in both "Link Binary With Libraries" and "Embed Frameworks". Noting that none of the frameworks listed under "Embed Frameworks" were ones managed by Carthage I removed the framework in question from "Embed Frameworks". I then re-built my project and everything works fine including the functionality enabled by the framework in question.

在我的例子中,问题来自podcast文件。我必须将我的测试项目添加到podfile:

target 'MyApp' do
    pod 'Firebase'
    target 'MyAppTests' do
        inherit! :search_paths
        pod 'Firebase'
    end
end

之后,我需要执行:

pod update

在我们的例子中,我们只是清理了“Copy Bundle Resources”中的任何碎片,只留下最小的项目。

我在XCode 14.2中也面临同样的问题

错误说

多个命令生成“/Users/bhaveshparmar/Library/Developer/Xcode/DerivedData/App-cgedsyimmqlucmcodsrdnwzllkat/Build/Intermediates.noindex/App.build/development-iphone emulator /App.build/Objects-normal/x86_64/ThemeLabel.stringsdata”

这是因为我的源代码包含2个同名ThemeLabel的文件,所以删除了一个ThemeLabel,问题解决了。

对我来说,是当我嵌入一个椰子足的框架时。您所需要做的就是将其从通用构建目标中的嵌入式内容选项卡中删除。
