问题 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? 回答1: armv7 is 32bit architecture that was supported by earlier iOS versions
