在Xcode 9中运行代码正常,但在Xcode 10中有一个错误。


当前回答

这个答案已弃用——XCode 12已经弃用了遗留构建系统,它将在进一步的版本中被移除

试试这个吧。 Xcode->File->Project Settings-> Build System -> Legacy Build System。

其他回答

如果你在核心数据中遇到问题,这个答案适合你。 转到你的文件名。xcdatamodeld并确保所有实体都有manual/None Codegen。

如果你的应用程序生成了与多个.app文件相关的错误,那么从“复制bundle资源”中删除。plist文件将不起作用。

如果该错误与.app文件有关,请执行以下步骤

Select the Target. Go to Build Phases tab. Remove the items listed in Output Files Compile the code if it compiles successfully then not follow the next steps. If code does not compile successfully and Xcode may give you an error related to "Library not found". Then add the missing library in General Tab in Linked Frameworks and Libraries that Xcode mentioned in the error. Keep adding these libraries (that Xcode ask through compile errors) in Linked Frameworks and Libraries until the code compiles successfully. Hope this helps.

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。

这里是另一个工作解决方案:(如果你使用自定义Pods)

在截图中选择侧边栏中的“Pods”作为亮点。 单击Build Phase。展开“头”部分。有3个选项,公共,私人,项目 展开Public,检查是否有重复的文件。删除它。完成了! !

我有同样的问题,我有一个更多的帮助应用程序在主应用程序和复制这个资源。在我的情况下解决为:-

1)目标-> 2)构建阶段2)复制文件(n项)3)删除复制文件。

Helper应用自动复制到Xcode 10.0中。
