WTF are Protocols ?
protocol lifeOfABear {
var fishEatenToday: Int {get}
func eatFish()
func eatHoney()
func ClimbTree()
func sleep()
// now all you have to do is make sure you have variable and functions implemented
class PhilTheBear: lifeOfABear {
var fishEatenToday: Int = 200;
func eatFish() {
print("Go down to the east river today")
func eatHoney() {
print("Walk over to the bee hive near the old tree")
func ClimbTree() {
print("climb up the first tree that has a blue jay")
func sleep() {
print("get a sold 12 hours")
