在Xcode 9中运行代码正常,但在Xcode 10中有一个错误。


当前回答

如果您手动创建实体的CoreDataClass和CoreDataProperties,请确保转到您的xcdatamodel并将检查器选项卡中的Codegen设置为“Manual/None”。如果设置为“类定义”,Xcode会自动为你创建一个重复的类。

其他回答

我是IOS开发的新手,我尝试了上面的答案,但它们对我不起作用。

我的XCode版本是12.4,Swift 5

我得到多个命令产生错误,而构建

我试图从错误列表中扩展错误,但双击它没有做什么,所以首先,我很难知道完整的错误。

所以我右键单击错误并复制到剪贴板,粘贴在文本编辑器中。

它显示了完整的错误

上面说哪部分有问题

Multiple commands produce '/Users/userName/Library/Developer/Xcode/DerivedData/ProjectName-fbeqffupediuiedlrplqjyhgyqna/Build/Products/Production-iphoneos/XCFrameworkIntermediates/GoogleAppMeasurement':
1) That command depends on command in Target 'GoogleAppMeasurement-iOS12.3' (project 'Pods'): script phase “[CP] Copy XCFrameworks”
2) That command depends on command in Target 'GoogleAppMeasurement-iOS14.1' (project 'Pods'): script phase “[CP] Copy XCFrameworks”

(我正在使用谷歌Firebase)

我很惊讶地看到,这些pod是为两个不同版本的iOS(12.3和14.1)编译的。

我发现,在活动目标配置中,我在部署信息部分设置了iOS 12.3,在项目级别信息选项卡的部署目标中设置了14.1

将两者设置为相同的所需版本,然后清理和构建解决了这个问题。

请让我知道设置2个不同的版本是否是一个错误。如果这不是一个错误,那么应该怎么做呢?

不允许我将构建系统设置为遗留系统 信息。plist在Copy Bundle Resources阶段不存在

在我的例子中,构建存档错误vs Xcode10

-1: Multiple commands produce '/Users/kk/Library/Developer/Xcode/DerivedData/react_carday_app-hjahojxsbvmmiyaklrhhuqljdfwv/Build/Intermediates.noindex/ArchiveIntermediates/react_carday_app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libyoga.a': 1) Target 'yoga' has a command with output '/Users/kk/Library/Developer/Xcode/DerivedData/react_carday_app-hjahojxsbvmmiyaklrhhuqljdfwv/Build/Intermediates.noindex/ArchiveIntermediates/react_carday_app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libyoga.a' 2) Target 'yoga' has a command with output '/Users/kk/Library/Developer/Xcode/DerivedData/react_carday_app-hjahojxsbvmmiyaklrhhuqljdfwv/Build/Intermediates.noindex/ArchiveIntermediates/react_carday_app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libyoga.a'

在你的Podfile中应该有类似bellow的东西

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end

    if target.name == "yoga"
      target.remove_from_project
    end
  end
end

然后运行pod install

在检查构建日志时,我注意到一个警告:

note: Using new build system
note: Planning build
note: Constructing build description
Build system information
warning: The Copy Bundle Resources build phase contains this target's Info.plist file '/Users/<redacted>/Repositories/Whitesmith/optimize-ios/Carthage/Checkouts/WSStatusBarNotification/Miscellaneous/Info.plist'. (in target 'JDStatusBarNotification')

如果这是你的情况,那就去你的目标:

构建阶段 拷贝包资源 删除info.plist。

转到Xcode 10,错误像

error: Multiple commands produce '/Users/uesr/Library/Developer/Xcode/DerivedData/OptimalLive-fxatvygbofczeyhjsawtebkimvwx/Build/Products/Debug-iphoneos/OptimalLive.app/Info.plist':

可解如下:

进入Xcode->File->Workspace/Project Settings-> Build System -> Legacy Build System。

在我的案例中,PDFGenerator正在生成一个信息。plist文件,我刚刚删除了它。
