I have an array like this:
let strNames = ["banana", "apple", "mango"]
I am looking for a result like this:
var abc = [Fruit(id: 0, name: "banana"), Fruit(id: 1, name: "apple"), Fruit(id: 2, name: "mango")]
In classic way I can do so far. Can anybody please help me mapping in Swift way?
var abc: [Fruit] = []
for i in 0..<strNames.count {
abc.append(Fruit(id: i, name: strNames[i]))
}
Initializers can be used as functions using this syntax.
["banana", "apple", "mango"].enumerated().map(Fruit.init)
It appears that your Fruit type matches up with EnumeratedSequence.Element exactly.
struct Fruit {
let id: Int
let name: String
}
If it didn't, you'd just need to create your own closure.
["banana", "apple", "mango"].enumerated().map {
Fruit(id: $0.offset, name: $0.element)
}
Thank you @Sweeper for your suggestions. Actually this is what I am looking for...
let abc: [Fruit] = strNames.enumerated().map { Fruit(id: $0, name: $1) }
Fruit.
