Question

假设我有两个相同长度的数组：

names = ["Adam", "Bob", "Colin"]
ages = [14, 11, 16]

我如何制作以下词典？

people = ["Adam": 14, "Bob": 11, "Colin": 16]

Answer 1

如果您使用 Swift 4 ，则可以使用 uniqueKeysWithValues 和 zip ：

let names = ["Adam", "Bob", "Colin"]
let ages = [14, 11, 16]

let people = Dictionary(uniqueKeysWithValues: zip(names, ages))

print(people) // ["Adam": 14, "Colin": 16, "Bob": 11]

否则，您可以将zip与for循环一起使用：

let names = ["Adam", "Bob", "Colin"]
let ages = [14, 11, 16]

var people = [String: Int]()
for (name, age) in zip(names, ages) {
  people[name] = age
}

print(people) // ["Adam": 14, "Bob": 11, "Colin": 16]

在Swift中将两个数组转换成字典
