arrays - Swift 乘法数组索引

Question

这里是klass1;

class Klass1 {

let name:[String]
let number:[Double]

init(name: [String], number: [Double]) {
     self.name = name
     self.number = number
     }
}

下课了

var data1 = [Klass1]()

let xxx = ["name1","name2","name3"]
let yyy = [1,2,3]

setupKlass1(){
data1.append(Klass1(name: xxx, number: yyy))
}

我想从 data1 中获取所有数据(每个名称和数字值)并作为 Klass2 附加到 data2

下面是Klass2；

class Klass2 {

let name:String
let number:Double

init(name: String, number: Double) {
     self.name = name
     self.number = number
     }

}
end of class
var data2 = [Klass2]()

Answer 1

我想你会喜欢这样的东西

var data2: [Klass2] = data1.flatMap {
    zip($0.name, $0.number).map {
        Klass2(name: $0, number: $1)
    }
}
