//  Demonstrates Swift-based reflection concept like Key-Value coding in Objective-C (but slower)
//   and use of @dynamicMemberLookup.
//
//  Uses Mirror to reference a property in a class or struct by string key name; 
//  Uses @dynamicMemberLookup to get the name of a property as a string, to reverse the reflection.

# Format Objectives

1. Suitable for editing by humans, especially those with minimal technology skills.
2. Readable by computers.
3. Readability by humans is preferred over reducing file size.

# Basic Format
* The basic line format is a name, some space(s) and a value.
* A record starts with RECORD or # (then an optional identifier).

Add the App Sandbox capability to an Xcode project when it is missing from the standard capabilities area.

(Straightforward to do but a pain to remember.)

1. If your project lacks a .entitlements file, create a new one:

• Menu: View > Navigators > Project
• Select the root level (project icon) of your project
• Menu: File > New > File...
• Use the Property List template

Swift 5.0

Swift 5.0 cannot use the #ffffff syntax directly. Here is the code I use for web-related projects. Supports alpha and three-digits.

Usage example (uppercase values are fine too):

    let hex = "#FADE2B"  // yellow
    let color = UIColor(fromHex: hex)
