The scheme ‘SSDKDemo‘ contains no buildables that can be built for the SDKs supported by the run destination Pengfei. Make sure your targets all specify SDKs that are supported by this version of Xcode.
解决办法:
在build setting 的列表里面,找到, iOS DEPLOYMENT TARGET这个选项,然后选择6.0,因为你的真机的操作系统可能没有升级倒最新版本,所以,选择3.2应该可以,现在你再试试,是不是可以找到真机了呢?
