ios - 根据条件将数组合并到字典中？

Question

我有两个数组:

First array = ["lines","lines","lines","lines"]
Second array = ["one","two","","three","four","","five","six","","seven","eight"]

我想将它们合并到一个带有嵌套数组的字典中:

Dict = ["lines":["one","two"],"lines":["three","four"],"lines":["five","six"],"lines":["seven","eight"]]

基本上，由于空格标准 ("")，第二个数组中的值应该被拆分，并在字典中分配为单独的数组对象。

Answer 1

试试这个解决方案:

let array2 = ["one","two","","three","four","","five","six","","seven","eight"] 
var splittedArray = array2.split { $0 == "" }

Playground 的结果:
