This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.


## Swift: Convert structs and enums to NSData and vice-versa
func encode<T>(var value: T) -> NSData {
    return withUnsafePointer(&value) { p in
        NSData(bytes: p, length: sizeofValue(value))
    }
}

func decode<T>(data: NSData) -> T {
    let pointer = UnsafeMutablePointer<T>.alloc(sizeof(T.Type))
    data.getBytes(pointer)
	func encode<T>(var value: T) -> NSData {
	return withUnsafePointer(&value) { p in
	NSData(bytes: p, length: sizeofValue(value))
	}
	}

	func decode<T>(data: NSData) -> T {
	let pointer = UnsafeMutablePointer<T>.alloc(sizeof(T.Type))
	data.getBytes(pointer)
