I'm running El Capitan/Xcode 7.3.1, but have been downloading Xcode 8 betas with some regularity. Sometime recently, Xcode 7 has lost track of the local docsets and goes out to Apple's site anytime I use documentation. I notice that Xcode 7's info.plist references an Apple URL in "Imported Type UTIs", for docsets, but I'm not brave enough to start editing that file to point to something local. When I look at older Xcodes, their Info.plist files look very different, so I haven't been able to do an apples to apples comparison. Any suggestions or pointers? (I can't upgrade to Sierra, since I have an important Fujitsu ScanSnap project in the works, and it's incompatible with Sierra.)
