Implementing types that conform to LocalizedError in Swift
//Proper way to implement error types. Implement `errorDescription`, not `localizedDescription` and the global handler `getErrorMessage(error: Error)` is easy to implement, not need a stupid switch case
//Key is implement `errorDescription` instead of `localizedDescription` and must not implement `localizedDescription` at all
import Foundation
struct E1: LocalizedError {
var errorDescription: String? {
return "E1's errorDescription"
}

self when initialising property with function, inheriting from NSObject

Found a bug in my code because of something very subtle:

class C: NSObject {
	var foo: String = {
		NSLog("non-lazy self: \(self)")
		return ""
	}()
	lazy var bar: String = {
 NSLog("lazy self: \(self)")
