Applications of Cognitive Theory in Data Modeling and Software Design

Written as both a refresher course on the mechanics of cognition in human psychology, and as the beginning of a working theory, wherein one might make some deductions from human psychology to broadly advance/improve the design of server software and data models for the industry en masse.

What's the point of this? I think psychology will inevetiably instruct the future of software design, in the same way neurobiology is beginning to impact the hardware engineering industry. >

# Swift Language Fundamentals

Swift is a modern programming language for Apple platforms (iOS, macOS, etc.) with these key characteristics:

1. Core Features:
- Type inference for automatic type detection
- Optionals for safe handling of missing values
- Closures for flexible function passing
- Memory safety by design
- Built-in error handling
