macOS.
Some Cocoa app wants to know whether the cursor moved from any point to a point
outside of some rect.
Currently I use polling (which looks kind of inefficient).
I tried NSTrackingArea, but this does not work:
1. if the cursor is initially NOT in the rect, the app does not get notified:
macOS 11+
Some Cocoa app which has to do:
1. something a few seconds later
2. some other thing repeatedly about every 0.1 second.
What is the most efficient (energy-wise) way to do this:
NSTimer (with tolerance)
NSRunLoop performSelector:target:argument:order:modes:
NSObject
// strange behaviour for probably all combining marks (macOS 12.4):
NSString *pintu = @"-ฺ";// HYPHEN-MINUS + THAI CHARACTER PHINTHU
// ok
NSString *test1 = pintu;
[ self printTestString: test1 ];
// prints: length 2 0x2d 0xe3a “-ฺ” ok: has prefix “

So now I have two working solutions:

2. using kStylisticAltThreeOnSelector (as suggested by you).
Thanks a lot. The hint of “kStylisticAlternativesType” was extremely helpful!

NSURL *url = [ NSURL fileURLWithPath: rawP
I want to remove all symlinks from a path.
stringByResolvingSymlinksInPath does NOT do this (e.g. it does not change: /tmp

I need (just for debugging purposes) to count something in a thread safe way.
This works, but is deprecated:
SInt32 counter;
- (IBAction)doSomething:sender
{
counter = 0;
some loop
{
IncrementAtomic( &counter );// 'IncrementAtomic' is
d
The Icu stuff (57.1) is included in macOS 12.
There is:
/usr/lib/libicucore.A.dylib
and Xcode has:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/libicucore.tbd
But I cannot find the headers.

I have a big array (like a few GB) which is operated upon by some functions.
As these functions act purely local, an obvious idea is:
- (void)someFunction
{
nbrOfThreads = ...
sizeOfBigArray = ... a few GB
stride = sizeOfBigArray / nbrOfThreads

This function works flawlessly in Release build:
func markAndTell( talk: Bool, number: Int)
{
let nbrOfThreads = 8
let step = 2
let itemsPerThread = number * step
let bitLimit = nbrOfThreads * itemsPerThread
var bitfield = [Bool](count: bitLimit, repeatedVal

I have a pure Swift class.
I want to do:
if self.dynamicType == SomeClass { … }
But the compiler won’t accept this (or any number of variations thereof).
isKindOfClass needs a “class object representing the Objective-C class to be
tested”.
How can this be done?
