Printing out the description of a variable in Xcode

The Xcode popups just don’t seem very reliable.

For example, here’s a screenshot I took with my mouse hovering over the first mapView in the list.

and here’s one where I hover over the third.

The debugger has stopped on the last line. Notice how I get a tooltip type popup on the first but not the third.

And finally here’s one where I hovered over the first but then moved down to the second mapView. Notice how the downward facing arrow has disappeared. If you look carefully it’s actually hidden under the popup (which hasn’t moved whilst the down arrow has).

What does that down arrow do?

It lets you Edit all in Scope or run a Service such as Search with Google. Doesn’t seem particularly useful and is very distracting.

It’s just another one of those not very useful icons that pop up and don’t seem very useful. For example:

The Run to Here green circular icon only pops up at the start of a line if you’re in the numbered lines section of Xcode (and only then if you’re in the right hand side of the gutter). If you move away it disappears and will only reappear if you move to another line and back again.

or the little i symbol which is particularly hard to get to appear and shows no tool tip whatsoever so I’m completely unclear what it actually does!
