使用适用于Mac Catalyst Apple Silicon的xcodebuild构建

问题描述

我正在尝试使用Xcode 12 beta 4构建支持Mac Catalyst的Apple Silicon的框架。该项目在Xcode中以“ Any Mac”为目标可以很好地构建。 如果我使用命令

xcodebuild -project "project.xcodeproj" -configuration "Release" -scheme "MyScheme" -destination "generic/platform=macOS,variant=Mac Catalyst,name=Any Mac"

我得到了错误

xcodebuild: error: Unable to find a destination matching the provided destination specifier:
        { generic:1,platform:macOS,variant:Mac Catalyst,name:Any Mac }
    Unsupported device specifier option.
    The device “My Mac” does not support the following options: name
    Please supply only supported device specifier options.
...
Ineligible destinations for the "MyScheme" scheme:
        { platform:iOS,id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder,name:Any iOS Device }
        { platform:iOS Simulator,id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder,name:Any iOS Simulator Device }
        { platform:macOS,name:Any Mac }

我不确定为什么在Xcode中正确构建目标时，为什么该目的地被列为不合格，或者在启用通用时，为什么xcodebuild似乎使用“ My Mac”设备。 如何使用xcodebuild在Apple Silicon上为Mac Catalyst进行构建？

解决方法

xcodebuild -project "project.xcodeproj" -configuration "Release" -scheme "MyScheme" -destination "generic/platform=macOS,variant=Mac Catalyst,name=Any Mac"

此命令现在可以在Xcode 12 beta 5中使用。
