Return/Pass new array to function (Swift 5)

In e.g. Java you can do something like this:

myFunction(new MyClass[]{myclass1, myclass2, myclass3})

Is there an equivalent in Swift?

I tried

myFunction([MyClass](myclass1,myclass2,myclass3))

and Xcode suggested to change it to

myFunction([MyClass](arrayLiteral: myclass1,myclass2,myclass3))

but the documentary (click) tells you not to call "arrayLiteral" directly.

Edit: The reason why I want to do this is a bit complicated:

I've got a class MyClass and created a bunch of instances that carry data: myclass1, myclass2, myclass3

init(name na:String, number nu:Int, content c:String) {....}

These instances I want to add to an array, which I'm then using to create an instance of a second class MyOtherClass:

init(name n:String, someotherinfo s:String, myclassarray m:[MyClass]) {....}

Creating the instance:

var myotherclassthing = MyOtherClass(name:"Test", someotherinfo:"Bla", myclassarray: ??????????)

This instance of MyOtherClass I'm then passing from my main View to a second View via a segue.

This should work

myFunction(["a","b","c"])

This works equally well if you want to return an array from a func

func test() -> [String] {
    return ["a", "b"]
}

And it works equally well with a custom class

MyOtherClass(name:"Test", someotherinfo:"Bla", 
             myclassarray: [MyClass(name: "A", number: 1, content: "AAA"), 
                            MyClass(name: "B", number: 2, content: "BBB")])
