It might seem like a primitive approach, but logging with time stamps should be able to highlight where the suckyness is. Run a log that displays the time delta from the last logging statement so

The results are stable and repeatable and do not depend on the order. Gerriet.

It computes the faculty of 300 000 (i.e. 1 * 2 * 3 * … * 299 999 * 300 000), a somewhat large integer. Yes, but I could not see anything unusual. Probably not. But maybe you could tell me, how I

It's a bit unusual for emulated code to run faster, but not impossible. Depending upon the operation, the order of execution could end up pre-loading values or accessing devices in such a way that the

Perhaps something is cached from the first run? Do you get the same results if you reverse the order? Tom

What is it doing? We would need to compare the tasks it’s doing so that we could estimate where any slowness would be. Have you profiled it using Xcode’s profiler? Can you add log statements so

I have a simple C command line tool. This takes 16 seconds when I run it in Xcode with “My Mac”. But only 11 seconds when run with “My Mac (Rosetta)” How can this be? I always assumed that

My app implements a report-generation function which displays reports in a presented view controller. The view controller includes an Activity Button, which uses UIActivityViewController to present

Apparently, later than iOS 13.x in the Simulator will not bring up 2FA and break Signin with Apple. Fun times, fun times. Cheers, Alex Zavatone

Hi. I’d like to share what I just played with this morning using Apple’s sample code and see if anyone is seeing the same things. The sample app on iOS, Juice, is here and is pretty easy to get

Iff the Thread Sanitiser is enabled on the main app, then its HelperTool will contain lots of Xcode stuff. The main app asks the HelperTool for its version, and if they don’t match, then a new

This is a wild guess, but are you building with Thread Sanitizer enabled? (The "tsan" in the missing library name suggests so.) That the named clang version (13.0.0) seems not to match your toolchain

I have an macOS app, which uses a privileged helper tool: de.mdenkmann.SW-Helper This helper tool crashes with (Console.app): ASI found [dyld] (sensitive) 'Library not loaded:

Properties can be structs just as much as they can be classes or other types. Structs are value types, and classes are reference types. That's the biggest difference. Does the model represent

We’ve all seen so many Swift references about when to use a struct as opposed to a class. But coming from Objective-C like lots of us, does anyone have any resources or guidelines for when and why

I have (macOS 12.3.1): struct ContentView: View { var body: some View { GeometryReader { metrics in VStack { ... some HStacks ... ZStack // Curves { ...

That is exactly what I was missing when I started this project to years ago in macOS 10.15.4. textSelection Availability macOS 12.0+ One minor problem: HStack { Text(“One

Can select and copy, but only the content of the invisible TextField, not the (visible) Text below. Gerriet.

So first I enabled isUserInteractionEnabled for my UILabel. Then, In viewDidLoad() I added: let interaction = UIContextMenuInteraction(delegate: self)
