building for iOS Simulator, but linking in object file built for iOS

Xcode版本升级到 12.0 以上之后, 在模拟器运行低版本报错:

解决方法

1.TARGETS选中项目 → Build Settings → 搜索VALID_ARCHS→ 加x86_64

2.Build Settings → 搜索Excluded Architecture→ 加arm64

3.Build Settings → 搜索Build Active Architecture Only→ 设置NO

之后模拟器运行即可

注意: 模拟器切回真机测试或者打包，要去掉VALID_ARCHS中的x86_64, Excluded Architecture中的arm64
