如何在swift中将一个数组拆分为两个数组

Question

我有一个数组，例如：

var coordinatesOut: [Double] = [1.0,2.0];

我如何拆分数组以便得到：

var coordinatesOut1: [Double] = [1.0];

var coordinatesOut2: [Double] = [2.0];

Answer 1

例如：

let a = ["a","b","c","d"]
let part1 = [a[0...1]]
let part2 = [a[2...3]]

Answer 2

var coordinatesOut1 = [Double]() 
var coordinatesOut2 = [Double]()

coordinatesOut1.append(coordinatesOut[0]);
coordinatesOut2.append(coordinatesOut[1]);
