Struct not being populated

问题

I have a struct called Item and wish to populate its variables.

struct Item {
    var title: String
    var others: [String]
}

Programs is an array of all the Item’s created.

var Programs = [Item]()

I created a struct Item by the following:

var entered = Item(title: hello1, others: ["hello2"])

The problem is that when I go to print the list of Items, the programs array is empty

print(Programs)

回答1:

You need to append it

print("Before :",programs)
let entered = Item(title: hello1, others: ["hello2"])
programs.append(entered) 
print("After:",programs)
