Why bother with a timer loop to animate the wiper when that functionality is
built-in through CoreAnimation?
Especially since you are using an image as the wave background.
CoreAnimation will move the wiper smoothly and accurately. All you have to do
is provide the distance it must travel and
I have a dialog which allows the user to select a folder containing data to be
processed, set various parameters that affect the processing, and displays the
result of the analysis. There is an NSPathControl (popup) to select the folder.
Inevitably the first thing the user does is choose a
A fairly simple way to implement a selection rectangle is to use
CALayer, but that only gives you the visual aspect. What does it
select? Answer that question first and that will tend to lead you to
the appropriate way to implement it.

current sample position, not a separate animation that is

This is a good idea. It would be better yet
You probably want to rethink what you mean by processing of data.
The table ALWAYS lazy loads, and only asks your data source for the
row it needs when it needs them. The user scrolls, more rows needed,
your data source supplies them. This is all VIEW stuff, nothing to do
with data

Have you designed it so that it only draws the minimum it needs to? For
example, if your audio

The docs say that with a view based table, the subviews (i.e. columns)
