Hey Brian,

I found that if I dragged any IBOutlet in customView.swift (step 7.Add Entire View as an IB Outlet in UIView File), it keeps crashing in

“let nib = bundle.loadNibNamed(“test”, owner: nil, options: nil)?[0] as! UIView”

it worked fine without dragging any.

My Xcode version is 10.1

I still can’t figure out why…
