Question

Answer 1

如果您使用的是 Swift 4，您可以使用 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，您可以使用 zip使用 for 循环:

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]
