It's my understanding that xcode-select isn't even supposed to exist anymore;
any copy you have might be left over from an older Xcode install.

In an attempt to figure out how well gesture recognizers work, I've built a
very simple app that uses a UIPanGestureRecognizer and using them to construct
a UIBezierPath that I then stroke, but I am getting strange artifacts on the

Well, my code doesn't show things being allocated and assigned to the
IBOutlets, but it shows a bunch of releases of the associated members. As
far as I can gather, the code is now correct. It is this asymmetry that
strikes me as messy and error-prone.

Except the nib loading behavior is vastly different on the two operating
systems. This is why the documentation goes into detail about both.
I'm doing an iPhone app. I'm not doing any Mac app.
I should simply have said "the nib-loading behavior".

I went through and removed all the IBOutlet notation from the members and
reconnected everything to the properties in IB. Also added release calls
for all the controls in dealloc. The app appears to be quite solid, with
no leaks or analyzer issues detected. I'm calling it done!

Sweet! I’ve found the solution to my own problem. Here it is, in case someone
else finds this thread wondering the same thing.
What I was trying to do was to keep track of the NSScrollView being resized,
and adjust the size of its document view as needed. Toward this end, I was

Hello Charles,
It sounds like you have the idea that constraints establish a minimum and
maximum size on a window (or view), and the window is free to take on any size
within that range. When you resize a window, it evaluates the constraints at
the proposed size. If would make the constraints

OK, I think I know why there weren't any leaks.
Per (possibly old) examples, I have "IBOutlet" in both the member-variable
declarations and the property declarations.
Now I'm realizing that IB will show two outlets: one for the member
variable itself, and one for the property when you have this:

Only the three heights you identified are supported. There isn't special sauce
for getting around that, though enforcement wasn't always there in the past.

The material quoted is post-ARC usage (not the use of "weak" and not "assign").
In the legacy paradigm material, you will see that pre-ARC. You can choose
"retain" or "assign" (or "copy", but I'll leave that out here). iOS outlets
should be held as "retain", and therefore need to be nil-ed in vi

If you want more control over credentials and certificate trust, you’ll need to
