+
+      1) Download an XCode dmg, specifically XCode_7.2.dmg
+      2) Install darling-dmg, available via: nix-env -i darling-dmg
+      3) Follow this shell history:
+
+      $ cd ~/
+      $ mkdir xcode
+      $ darling-dmg Xcode_7.2dmg xcode
+      $ cd xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
+      $ mktemp -d
