I'm trying to build llama.cpp, a popular tool for running LLMs locally on macos15.1.1 (24B91) Sonoma using cmake but am encountering errors. Here is the stack overflow post regarding the issue: https://stackoverflow.com/questions/79304015/cmake-unable-to-find-foundation-framework-on-macos-15-1-1-24b91?noredirect=1#comment139853319_79304015

I recently encountered an issue with Xcode 16.2 while attempting to integrate Settings.bundle into a new app. I added Settings.bundle as a new file (using the provided template), but when I ran the app (the default "Hello World" project), the expected three default controls (Name, Enabled, Slider) did not appear in the app's settings. To troubleshoot, I downgraded my system to macOS Sonoma 14.7.2 and Xcode 15.4 (on a 2023 Mac Mini, M2). After this downgrade, everything worked as expected. With a new project, adding Settings.bundle, and running the app, the settings entry for the app appeared, including the three default fields. This behavior suggests a potential issue or incompatibility with Xcode 16.2.

I found when I put a webView on the screen and then remove it, several properties in TableView including firstResponderView, FirstResponderIndexPath, and FirstResponderViewType have changed. These properties are hidden and I cannot change them. firstResponderView strong holds my cell, resulting in my cell not being able to call didEndDisplayCell when it slides out of the screen as expected. What should I do to avoid firstResponderView from strong holding my cell, or what should I do to release it?

"the compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions" ...... it killing me !!!!

Here is a relatively simple code fragment: let attributedQuote: [NSAttributedString.Key: Any] = [ .font: FieldFont!, .foregroundColor: NSColor.red] let strQuote = NSAttributedString.init(string:"Hello World", attributes:attributedQuote) strQuote.draw(in: Rect1) It compiles without an issue, bur when I execute it, I get: "*** -colorSpaceName not valid for the NSColor <NSColor: 0x6000005adfd0>; need to first convert colorspace." I have tried everything I can think of. What's going on?

Hi All, I am from a non tech background and always felt a need that I am missing on the most interesting skills in today's world. I wish to learn Xcode to build applications and much more. Could any of you kindly suggest how I can learn and engage online. Thank You Govind

Hi, we have a CFArray, which we store in a CFDictionary and this in a SCPreference. When loading it from the SCPreference the order of the CFArray contents is undefined. All data is there though. Is this the intended behaviour? Is it possible to ensure the correct data order? Thanks, any hint is highly appreciated!

For some reason Xcode said my certificate was revoked. Developer support says it’s active. Could someone point me towards the steps to reactivate it?

Good evening. I have come up with this amazing and revolutionary idea that is going to change the ent world for the better. I’m a 23 year old Design Engineer from Greece and I would like to come to direct contact with the Apple Design Team, in order to discuss this project and the best case scenario, sell it to you. The foldable iPhone is not a good idea. Its not revolutionary and it’s going to leave a big black mark in Apple history. With my idea, the whole world will see again the greatness of the biggest company in history.

I am porting an old app from ObjC. The app uses many defined constants such as: #define COM_OFFSET 12.5 and many variables that are read and/or written throughout the App, such as: PCDate* Dates[367]; @class PCMainView; PCMainView* MainView; in one file called "PCCommon.h" How do I duplicate this function in Swift? I have looked around and have found no help. Thanks in advance.

We enabled WebGPU feature flag on Safari on iOS 18.2. This does give Safari an access to GPU but WKWebView still doesn't have GPU access. Can WKWebView not access GPU through Safari feature flag? Is there some other mechanism through which we can enable GPU access for WKWebView? We are testing gpu access by loading : https://webgpureport.org/ Regards Saalis Umer Microsoft Safari Feature Flag - webgpu = true Safari GPU Access: WKWebView GPU Access:

Dear my fellow developer, Question: why viewDidLayoutSubviews is getting called when I kill the app? is that normal? That behavior only happens on this device: iPhone 8 iPhone SE On the newer iPhone that will not happen. Thank you
