Swift 4 initWithObject equivalent

New to Swift. I have an Objective-C piece of code which looks like this:

self.imageArray = [[NSMutableArray alloc] initWithObjects:@{@"name":@"James",@"image":@"1.jpg",@"Address":@"xyz"},
                  @{@"name":@"Doe",@"image":@"2.jpg",@"Address":@"xyz"},nil];

How can i use the same initWithObjects function with Swift. I have read online that we need to create an extension and then use the zip function. However from the docs it seems the zip function only takes 2 sequences. My imageArray has dictionary objects consisting of 3 different keys/values.

I tried the following, but not sure how to assign the values to the respective key:

  extension Dictionary{

        for (name, address, image) in zip(names, address, images) {
        self[name] = names
        }
    }

In Swift, we'd probably use a native Array (designated with the [ and ]) rather than a NSMutableArray object. The Swift equivalent of your code snippet would be to use a Swift Array of Dictionary objects:

var imageArray: [[String: String]]?

And then:

imageArray = [["name": "James", "image": "1.jpg", "Address": "xyz"],
              ["name": "Doe",   "image": "2.jpg", "Address": "xyz"]]

Having said that, you'd probably want to use custom object type:

struct PersonImage {
    let name: String
    let image: String
    let address: String
}

Then define imageArray to be an array of PersonImage:

var imageArray: [PersonImage]?

And then

imageArray = [PersonImage(name: "James", image: "1.jpg", address: "xyz"),
              PersonImage(name: "Doe",   image: "2.jpg", address: "xyz")]
