How to filter a dictionary using a different array-CodePudding

I have an array (items) and an array of dictionaries (data) in Swift:

let items = ["test", "2test"]


var data = [Model(title: "Title", number: 1, weight: 10, text: "text1", url: "http://google.com", questRepeat: false, code: "test"), 
           Model(title: "Title1", number: 1, weight: 10, text: "text2", url: "http://google.com", questRepeat: false, code: "1test"), 
           Model(title: "Title2", number: 1, weight: 10, text: "text3", url: "http://google.com", questRepeat: false, code: "2test")]

I'd like to create an array that contains those arrays of dictionaries whose "code" don't equals to the numbers provided in the 'items' array. Aka I'd like to end up with having an array of:

var result = [
    Model(title: "Title1", number: 1, weight: 10, text: "text2", url: "http://google.com", questRepeat: false, code: "1test")
]

They seem insanely complex for this task.

Is there a clever way to do this using predicates or something else?

CodePudding user response：

By id I think you mean the code property in your Model as this is the only data that seems to match what is in your items array.

You could do something like this with filter on the data array

let items = ["test", "2test"]


var data = [Model(title: "Title", number: 1, weight: 10, text: "text1", url: "http://google.com", questRepeat: false, code: "test"),
            Model(title: "Title1", number: 1, weight: 10, text: "text2", url: "http://google.com", questRepeat: false, code: "1test"),
            Model(title: "Title2", number: 1, weight: 10, text: "text3", url: "http://google.com", questRepeat: false, code: "2test")]

let result = data.filter { !items.contains($0.code) }
print(result)

This should give you:

[Model(title: "Title1", number: 1, weight: 10, text: "text2", url: "http://google.com", questRepeat: false, code: "1test")]
