Learn to build Mac App using Swift

Using App Sandbox for macOS App

Sandboxing is the idea to keep data access controllable for the application.

Every coin has two sides. Let’s look at both.

Without Sandbox

NSView and CALayer

I recently come across animation problem in building macOS app. I was not able to display a transformed layer properly. Things went funky. Thus I decided to spend some time in reading the documentation once again.
