Creating an app icon that can be use for macOS apps

parsing all the macOS Sierra GUI styles takes between 5-10secs on a 4-core 2013 MacBook Pro Retina. To make it faster

Fitting a circle Given 4 points. p1,p2,p3,p4

Reducing for-loops is a great way to maintain readability and maintain code modularity. “Data science” methods like map, flatMap, filter and reduce are awesome building blocks for functional programing in swift, but you can also build your own custom methods that do similar things.

Basic XML parsing in swift (Mac):

Sorting things in swift

In its simplest form you click a button and it loads a css and recursively calls setSkin on the UI.

Encoding and decoding of text

Some shell research

CVDisplayLink is a timer object that allows your application to synchronize its drawing to the refresh rate of the display. ==It’s highly useful when you want to combine animation with user interactions==, something that is not easily handled by transitions or stock animations.

A simple event system that propagates events through hierarchical classes

Researching hit-testing of sub views

Great method that asserts if an instance is of a class type or of a protocol type

Customize a window with any design and behavior, everything is also animatable.

As a programmer I sort and collect a lot of research, my problem has always been were do I store all this research?

When you want to assert if a digit is a digit i used to use a simple conditional back referencing pattern.

A graphics framework built on Quartz

NOTE: it does require that each class extends the same protocol and that they have similar init method

Drop this in playground and your on your way:

Extracting RGBA values from NSColor

**Casting Array to Array**

This is a great way to add context to “data container classes” as it is then easy to debug all the variables in the instance

My notes on the Equatable protocol in swift

Here is a pure swift implementation of dynamic class types. It does require the classes to extend the same protocol.

But if you combine a swift enum with RegExp matches and add ($n ) to your capture groups you can simulate named capturing groups.

In order to support GradientLine it was necessary to go all the way down to the core , namely Quartz which is part of CoreGraphics. So currently implementing a routine to support GradientLine Directly.
