swift - 从数组中提取元素并将它们放回另一个数组。？

Question

假设我有一个包含 10 个元素的数组。说，

var ArrayElemts : ["1","2","3","4","5","6","7","8","9","10","11"]

现在如何将 0 到 5 的元素保留在一个数组集中，而将 6 到 10 的元素保留到另一个数组集中？

Answer 1

使用 [0...5] 创建一个 ArraySlice，然后使用 Array 将其转换回数组:

var arrayElemts = ["1","2","3","4","5","6","7","8","9","10","11"]

let first = Array(arrayElemts[0...5])
let second = Array(arrayElemts[6...10])

print(first)   // ["1", "2", "3", "4", "5", "6"]
print(second)  // ["7", "8", "9", "10", "11"]
