var animalArray: [String] = ["Dog", "Cat", "Fish", "Owl", "Beaver"]
animalArray.removeAtIndex(4)
//animalArray now contains: ["Dog", "Cat", "Fish", "Owl"]
/*Alternately, if you wish to save the value before you remove it:*/
let stringAnimal = animalArray.removeAtIndex(4)
//Saves "Beaver" to the string constant stringAnimal and also removes it from the array.
