I had some trouble attempting to build an XCFramework of OpenCV, but I finally got a successful build with the following steps:

Clone the OpenCV repo:

git clone git@github.com:opencv/opencv.git
cd opencv

Disable building with libjpeg-turbo[^1] by applying a patch:
```
git apply path/to/opencv-5-28-50.patch
```

macOS 10.15 System Preference Panes

Below are a list of System Preference pane URLs and paths that can be accessed with scripting to assist users with enabling macOS security settings without having to walk them through launching System Preferences, finding panes, and scrolling to settings. Not all panes have an accessible anchor and some are OS specific.

To find the Pane ID of a specific pane, open the System Preferences app and select the desired Preference Pane. With the pane selected, open the ScriptEditor.app and run the following script to copy the current Pane ID to your clipboard and display any available anchors:

tell application "System Preferences"
	set CurrentPane to the id of the current pane
	set the clipboard to CurrentPane

Sketch 43 files JSON types

Based on the example file from the announcement blog post http://sketchplugins.com/d/87-new-file-format-in-sketch-43

type UUID = string // with UUID v4 format

type SketchPositionString = string // '{0.5, 0.67135115527602085}'

type SketchNestedPositionString = string // '{{0, 0}, {75.5, 15}}'

C++ Pointer Tutorial

Because pointers can be ugh

"Regular" variables (not pointers)

To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".

When declaring a variable by identifier (or name), the variable is synonymous with its value.


	class Number /* class cluser */ {
	class Int8: Number {
	var value: Swift.Int8
	init(_ value: Swift.Int8) { self.value = value }
	}
	class Int: Number {
	var value: Swift.Int
	init(_ value: Swift.Int) { self.value = value }
	}

	var radians: Float {
	return GLKMathDegreesToRadians(self)
