映射字典键以添加值-Swift [英] Map Dictionary Keys to add values - Swift

问题描述

我有两个字典:数据字典和结果字典

I have two dictionaries: a data dict and a results dict

var data    = ["flushes": 0.0, "times": 0.0, "glasses": 0.0, "showers": 0.0, "brushings": 0.0, "loads": 0.0, "washings": 0.0, "baths": 252.0, "dishes": 0.0]
let results = ["flushes": 21.0, "times": 0.0, "glasses": 0.0, "showers": 150.0, "brushings": 4.0, "loads": 0.0, "washings": 5.0, "baths": 0.0, "dishes": 9.0]

我想知道如何基于键添加类似的值，并且只有一个字典.

I am wondering how to add like values based on key and have only one dictionary.

推荐答案

假设data是可变的，则应这样做:

Assuming data is mutable, this should do it:

data.merge(results, uniquingKeysWith: { $0 + $1 })
