[Custom Namespace] An example of how to create a custom namespace for your app to avoid clobbering existing names #swift

CustomNamespace.swift

import Foundation

/**
 A custom namespace _へ__(‾◡◝ )>.
 
 General pattern would be:
 ```
 extension CustomNamespace where Base: UIView {
    // This property does not override the existing one
    var safeAreaInsets: UIEdgeInsets {
      return .zero
    }
 }

 view.cu.safeAreaInsets
 ```
 
 With this approach we can have more specialized methods and properties using
 `Base` and not just specialized on a common base type.
 */
final class CustomNamespace<Base> {
    let base: Base

    init(_ base: Base) {
        self.base = base
    }
}

/// A protocol that boxes up the type into CustomNamespace automatically
protocol CustomNamespaceCompatible { }

extension CustomNamespaceCompatible {
    static var cu: CustomNamespace<Self>.Type {
        return CustomNamespace<Self>.self
    }

    var cu: CustomNamespace<Self> {
        return CustomNamespace(self)
    }
}

// MARK: - Default Extensions
extension NSObject: CustomNamespaceCompatible { }
