cocoa:Make sure your targets all specify SDKs that are supported by this version of Xcode
macos, xcode
Solution
I've met with this problem. In my case, the following steps can solve it:
your project -> target -> Build Setting
Modify following items: 1.Base SDK ; 2.Architectures ; 3.iOS Deployment Target.
And then clean and build the application.
Problem
The scheme 'PrintingWebView' contains no buildables that can be built for the SDKs supported by the run destination My Mac 64-bit. Make sure your targets all specify SDKs that are supported by this version of Xcode.
