First guess would be not to explicitly set -anchorPosition. It defaults to
(0.5, 0.5), which refers to the middle of the bounds, and transforms (like
scaling) are applied relative to that position.

I’m working on an Obj-C app that got started a bunch of years ago and thought
that I would start migrating some of the smaller pieces over to Swift.
Some existing Obj-C methods are of the form:
+ (nullable __kindof NSManagedObject) someFooThing;
Right now I have

For slide shows that I’ve seen, they typically display each image for several
seconds at a time. If that’s the case, why can’t you just load the next image
from disk on a background queue while the current image is being displayed and
not have to worry about memory usage needed to cache
I don’t have an answer for your question, and I know that this doesn’t actually
answer it below, but it may still provide some info to help you move forward.
The windowing system is always working in points from a coordinates point of
view. So window.frame and view.frame are in points, not
You mentioned creating and managing threads on your own, but that’s what
NSOperationQueue —and the lower-level DispatchQueue— does. It also will be more
efficient with thread management since it has an intimate understanding of the
capabilities of the processor, etc., and will work to do the
One way to speed it up is to do as much work as possible in parallel. One way
—and this is just off the top of my head— is:
1. Create a NSOperationQueue, and add a single operation on that queue to
manage the entire process. (This is because some parts of the process are
synchronous and might
The view hierarchy doesn’t go through a layout pass until after it is added to
a live view or window. At awakeFromNib time it’s still essentially a snapshot
of the layout in the nib since it hasn’t yet been inserted into the “context”
that will allow the layout engine to determine how big all
