iOS Xcode 8 not displaying docs/parent class Swift files + errors super slow + no code colouring

[patent10021]

When I comd-click on a class, object etc I get zero deep-links into the Xcode 8 docs or parent class Swift files. What's going on? Should I not have Xcode 7 on my machine at the same time?

Also error updates are super slow to display AND my code isn't color-coded according to functions, methods, classes, structs, variables etc.

Beta is what's going on. You can run Xcode 7 alongside it no problem.

Delete your project's derived data and wait for it to reindex.

Yeah I already deleted Derived Data.

What I realized is that this was happening only in Playgrounds and not Projects for some reason.

Even though it's beta errors shouldn't be so slow to display and update.
