Get the sum of the values of the same label from the struct

I need to add the unappeared to the Array from this information. If there is a duplicate, the money will be summed up and then saved into one. How can I achieve this? The data may be a lot.

import UIKit
struct TestData {

let Label : String

var Money : Double

}
var SaveDate = TestData

var TestD = TestData

SaveDate.append(TestData(Label: “test1”, Money: 55))

SaveDate.append(TestData(Label: “test1”, Money: 35))

SaveDate.append(TestData(Label: “test2” , Money: 15))

SaveDate.append(TestData(Label: “test1” , Money: 10))

SaveDate.append(TestData(Label: “test3” , Money: 30))

print([{Label “test1”, Money 55}, {Label “test1”, Money 35}, {Label “test2”, Money 15},{Label “test1”, Money 10}, {Label “test3”, Money 30}])
//Result presentation

//Label1 = test1 , Money = 100

//Label2 = test2 , Money = 15

//Label3 = test3 , Money = 30
