I recently wrote an article on getting gtk auto complete/syntax highlighting on macOS
its a genuinely fun hobby to make portable software, and this method will ultimately help in porting software to the macOS platform
a copy and paste:
before I continue, I want to mention that emacs auto completion, using company-mode, is rather slow when it comes to parsing a ton files, and in some configurations, especially recursively when it comes to parsing and displaying functions and macros, even when using the semantic auto complete system, but I do believe it speeds up when you initially parse and save to ctags or when you build a semanticdb, functions such as g_signal_connect() and macros such as G_APPLICATION however, did not work with company modes auto complete, but worked with flycheck on the fly syntax checking, using this method, and I haven’t had time to perfect an emacs configuration; maybe some time next week
you will need gtk installed from brew or ports, since gtk has trouble compiling from source on some Mac configurations. this method works with whatever version of gtk is reported by pkg-config –cflags (pkg-config --cflags gtk. you will also need pkg-config installed, multiple installations of gtk can be used and utilized
but the emacs plugins you’ll need are (and you’ll need to connect to Melpa using list-packages https://melpa.org/#/getting-started to have these automatically downloaded and configured):
company
company-c-headers
flycheck
flycheck-pkg-config
exec-path-from-shell (this allows x11emacs to read the shells configuration, may be option for terminal based emac uses)
optional: function-args-mode, but when fa-show-auto is used, it breaks themes in emacs
download all of them through M-x list-packages (which means pressing alt+x, macOS option+x, which should issue an input on the bottom of emacs, where the status bar is), after that, type list-packages or use auto completion, aka ctrl+tab to cycle through possible candidates
open a c file (C-f ~/test.c) (which is control+x, macOS control+x)
type in:
M-x semantic-mode
M-x semantic-customize-system-include-path
in semantic-customize-system-include-path, add the path to the gtk version you intend to develop for, in my case /opt/homebrew/Cellar/gtk4/4.16.12/include/gtk-4.0 using the text based interface; you should be able to use your mouse (click ins after where it says /usr/include. semantic is included in emacs. options are automatically saved at command)
M-x exec-path-from-shell-initialize
M-x flycheck-mode
M-x flycheck-pkg-config
in flycheck-pkg-config, press enter, and then type the name of the version of gtk that provides valid input from pkg-config (ie gtk4)
M-x global-company-mode
if you need to bind ctrl+tab to auto complete, you can add this to your config (~/.emacs.d/init.el)
(global-set-key (kbd “C-”) ‘company-semantic)
this will do most of the grunt work when plugins are installed (ctrl-tab shows a window to auto complete, ctrl+` (thats the key before 1, with shift it becomes ~) shows function argument. fa-show-auto automatically shows function prototypes, but can break emacs themes:
(require ‘package)
(add-to-list ‘package-archives ‘(“melpa” . “https://melpa.org/packages/”) t)
;; Comment/uncomment this line to enable MELPA Stable if desired. See package-archive-priorities
;; and package-pinned-packages. Most users will not need or want to do this.
;;(add-to-list ‘package-archives ‘(“melpa-stable” . “https://stable.melpa.org/packages/”) t)
(package-initialize)
(global-company-mode t)
(global-flycheck-mode t)
(semantic-mode t)
(function-args-mode)
(global-company-mode t)
(global-flycheck-mode t)
(semantic-mode t)
(function-args-mode)
(global-set-key (kbd “C-”) ‘company-semantic)
(global-set-key (kbd “C-`”) ‘fa-show)
if you need to compile from inside emacs, I would make a Makefile according to the gtk tutorial on gtk.org
I also have another article on getting Xcode to work with gtk, which is more reliable: https://unix-world.com/2025/01/25/getting-gtk4-to-work-in-xcode-with-auto-complete-and-syntax-highlighting/
website is unix-world.com and I welcome any and all traffic !

My account was hacked and this was purchased through it. Im hoping someone sees this so and that ive left my mark that i got into his developer account be sheer luck and determination. Ive tried to gain access back into my apple id account with no luck, even contacting apple support. They got into all my online accounts.
Im hoping something can be done eventually, but untill then, whoever is controlling my account and incase i get kicked off, cer i grafu!

I'm running into issues with iOS respecting the HTTP 410 "Gone" response type.
Setup:
Using the native iOS Calendar app, add a new subscription calendar. "Add Subscription Calendar"
Add the URL of a ICS calendar subscription that you control, e.g. https://mywebsite.com/userfeeds/23/cal.ics
Make sure to select the "Account" option and choose "On My iPhone/iPad". Set the query amount to 15 mins.
Calendar events show as expected, device queries the latest updates from the server every 15 minutes. Server returns HTTP 200 with the .ics contents.
Now, assume there is a need for the feed to end - maybe the user unsubscribed to mywebsite.com. There is currently no way for the mywebsite.com server / response to tell the device the feed has ended and it should stop requesting. If the user forgets to go to calendar and manually unsubscribe the device will continually ping the server every 15 minutes indefinitely. It's turning into a virtual DoS for my platform.
iOS should respect the HTTP 410 "Gone" header or something similar. If the server returns a HTTP 410 response code for https://mywebsite.com/userfeeds/23/cal.ics X amount of times, the feed should be automatically removed.
I've opened several tickets over the last 3 years and have not even had a status change on the tickets.
Does anyone know how to resolve this or a work around?
its crazy on my iphone 11 pro max . all of a sudden my battery is not recognized down to 1% keeps crashing cant open any apps keep rebooting absolutely the worse . after all this am finally gonna have to leave the apple echo system. apple seams to be a huge failure at the time.
any one ger tips on this cause am heading to downgrade possible 18.2 cause all that issue did not exist till 18.3 beta

Hi all, I'm working for a publisher, and we're looking to bring some of our PC/console titles over to Apple Arcade - how viable is this? Is Unity or Unreal Engine easier to port from? Does anyone have any contacts with porting studios who have done this before? Thanks

Hello all.
I am currently developing a database app of particular products for people who collect this item. Let's say model airplanes. People can look at their list of model airplanes and also see a collection of airplanes by model companies.
I want to offer a link from a product in my app to a local retailer's website who sells this product on their website. Not just their base site, but directly to the products page. Meaning each product in my database will have a unique link to an external product page. This could also include links to Ebay or Amazon if local retailer doesn't sell the product.
Is this sort of feature allowed inside App Store Apps as technically it's not an in-app purchase? I do see some vague answers around but none that target this specific circumstance.
Thankyou in advance.

Hi Everyone,
I’m currently working on a flow where a web page redirects to our app to perform certain actions, and then returns the user back to the browser. However, on iOS, the only way to go back to the browser is by using the openURL method. The issue is that this method can only open the browser app itself—it can’t control which tab or page is shown, so the user doesn’t return to the original tab they came from. The same limitation also applies to Android.
Furthermore, iOS doesn’t allow an app to programmatically return to the previous app (in this case, the browser). While Android doesn’t have an official way either, in some cases, the OS automatically returns to the previous app when ours is closed.
I’d like to ask:
Is there any known method or workaround that allows returning from my app back to Safari (or the default browser) and restoring the previously active web page or tab?
Or, is there any way to programmatically return to the previous app from within my app?
Thanks in advance for your support!
I am using HelloPhotogrammetry in Xcode
I can make one model with something like
HelloPhotogrammetry.main([path_to_folder_of images, path_to_output/model.usdz, "-d", "medium", "-o", "unordered", "-f", "high" ])
But how would I request several models simultaneously? I only want to vary the detail.
[
("/Users/you/Desktop/model_medium.usdz", detail: .medium),
("/Users/you/Desktop/model_full.usdz", detail: .full),
("/Users/you/Desktop/model_raw.usdz", detail: .raw
]
I was experimenting with the screen time controls to see how it affected an app I am working on and I created a screen time passcode that I later forgot. Any fix? I can't find the "forgot passcode" button anywhere and I am now unable to turn off find my as a result.
Hi Apple Developers!
I’m using the DetectBarcodesRequest function to identify QR codes in some images and PDFs.
However, I’m facing an issue where the function doesn’t detect the barcode on certain documents and machines, while it works on others using the same document.
The only common factor I’ve noticed is that the machines that successfully identify the QR code of the “problematic” document are all heavy developer machines that have Xcode installed. Interestingly, this doesn’t seem to be related to processor type (Intel vs. Apple Silicon).
Could you please provide some guidance or leads on how to resolve this issue?
i am using this code
public static bool CheckForForceUpdate()
{
try
{
Version latestVersion = new(GetLatestVersion());
Version currentVersion = new(AppInfo.VersionString);
if (latestVersion != null && currentVersion < latestVersion)
{
NSUserDefaults.StandardUserDefaults.SetBool(true, StorageKey.IsForceUpdate);
return true;
}
else
{
NSUserDefaults.StandardUserDefaults.SetBool(false, StorageKey.IsForceUpdate);
return false;
}
}
catch (Exception ex)
{
Console.WriteLine("CheckForForceUpdate....." + ex.Message);
return false;
}
}
public static string GetLatestVersion()
{
try
{
string appId = "1586153397"; // Replace with your App Store app ID
string url = $"https://itunes.apple.com/lookup?id={appId}";
using (HttpClient client = new HttpClient())
{
var response = client.GetStringAsync(url).GetAwaiter().GetResult();
var json = JObject.Parse(response);
var latestVersion = json["results"]?[0]?["version"]?.ToString();
return latestVersion;
}
}
catch (Exception ex)
{
Console.WriteLine("GetLatestVersion..." + ex.Message);
return null;
}
}
The value of latestVersion should 2.1 in my production app i am not able to get this
hence i am not able to achieve Force Update functionality
