I have upgraded to Xcode8 but need an older sdk(10.10) for some projects.
I have copied MacOSX10.10.sdk from an older xcode to the same directory containing MacOSX10.12.sdk. However, when trying to select the base sdk, I am only give the choice of MacOSX10.12.sdk.
Pics below showing my sdk directory and the options xcode is giving me.
I have also tried 'Other' and changed the 12 to 10, but the sdk was not found.
Why am I not given the option to select MacOSX10.10sdk?
