在 Swift 中创建具有不同数据类型的空多维数组

Question

I'm trying to figure out how to create a structure with multidimensional array.

I got it working for 1D array:

struct example1 {

var user: [String] 

}

but when I try to create an array with String, String, Int and a Bool it gives me "Expected ']' in array type" error

struct example2 {

var user: [[String], [String], [Int],[Bool]]

}

How to create empty multidimensional array that would work in structure like mine?

Answer 1

Multiple arrays are bad practice for several reasons.

Create a struct User , each instance holds all information of one user

struct User {

    let name : String
    let email : String
    let age : Int
    let someBoolean : Bool
}

Declare the array

var users = [User]()

and add an item

let newUser = User(name: "Foo", email: "foo@something.com", age: 12, someBoolean: false)
users.append(newUser)
