迭代字典时如何避免swift中的重复键错误

概述我正在练习 swift,我正在尝试迭代一个字典来打印密钥,但它给了我一个 fatal error: Dictionary literal contains duplicate keys 如何删除错误？ let people = ["age":14, "age":15, "age":75, "age":43, "age":103, "age":87, "age":12]for (key, valu 我正在练习 swift,我正在尝试迭代一个字典来打印密钥,但它给了我一个

Fatal error: Dictionary literal contains duplicate keys

如何删除错误？

let people = ["age":14,"age":15,"age":75,"age":43,"age":103,"age":87,"age":12]for (key,value) in people {    print(value)}

解决方法 每个字典键必须是唯一的

let people = ["age1":14,"age2":15,"age3":75,"age4":43,"age5":103,"age6":87,"age7":12]for (key,value) in people {    print(value)}
