转换为ARC-LLVM编译器3.0错误 [英] Convert to ARC - LLVM compiler 3.0 Error

问题描述

我打开了我的一个较旧的项目，并从编辑/重构"菜单中选择了"Convert to Objective-C ARC".我收到以下错误:

Apple LLVM compiler 3.0 Error

Error in format of file: /Users/myUserName/Library/Developer/Xcode/DerivedData/ProjectName-fkjvtdsoypoyrdcedtarbtypupor/Build/Intermediates/ProjectName.build/Debug-iphoneos/ProjectName.build/ProjectName-arc.migrate/remap

这是我需要在Finder中手动删除某些文件/文件夹然后再试一次的情况之一吗?我只是删除了项目"Build"文件夹中的所有内容，然后做了Product/Clean并再次尝试，但仍然遇到相同的错误.

解决方案

显然，当您转换为Objective-C ARC"时，无法将目标设置为iOS设备.

当我将目标设置为模拟器时，我能够毫无错误地转换为ARC.

I opened up an older project of mine and chose Convert to Objective-C ARC from the Edit/Refactor menu. I am getting the following error:

Apple LLVM compiler 3.0 Error

Error in format of file: /Users/myUserName/Library/Developer/Xcode/DerivedData/ProjectName-fkjvtdsoypoyrdcedtarbtypupor/Build/Intermediates/ProjectName.build/Debug-iphoneos/ProjectName.build/ProjectName-arc.migrate/remap

Is this one of those situations where I need to manually delete some files/folders in Finder and then try it again? I just deleted everything in the "Build" folder of the project, then did Product/Clean and tried it again, but still getting the same error.

解决方案

Apparently you cannot have the target set to iOS Device when you "Convert to Objective-C ARC"

When I set the target to the simulator, I was able to convert to ARC with no errors.
