Xcode 构建目标差异——arm64 和 armv7、arm64 [英] Xcode build target difference - arm64 and armv7, arm64

问题描述

本周我在 Xcode 上为 2 个不同的应用程序创建了 2 个新项目.由于某种原因，项目之一总是无法为设备目标编译.然后我意识到两个项目的设备目标是不同的.对于工作项目Any iOS Project (arm64)"构建失败的项目有Any iOS Project (armv7, arm64)"

是什么导致设备目标以这种方式改变，有什么区别?

解决方案

armv7 是早期 iOS 版本支持的 32 位架构

I had created 2 new projects on Xcode this week for 2 different apps. For some reason one of the project always fails compiling for the device target. I then realized that the device target is different for both the project. For the working project "Any iOS Project (arm64)" The project which fails to build has "Any iOS Project (armv7, arm64)"

What causes the device target to change this way and what is the difference?

解决方案

armv7 is 32bit architecture that was supported by earlier iOS versions up till 10.3.4. arm64 is 64bit architecture which is supported by newer devices.

If your project has minimum iOS version which is below iOS 11.0, Xcode will automatically pick both armv7 and arm64.

In case if Xcode does not pick the required architecture automatically, it can be added in build settings as shown below:
