Hi,
When I am defining a struct I find myself often using a style as shown in the
following example:
struct Foo {
var greeting: String
var x: Int
var y: Int
var z: Int
init(greeting: String, x: Int = 1, y: Int = 2, z: Int = 3) {
self.greeting = greeting
self.x = x
self.y = y
self.z = z
}
}
This enables one to write code when one doesn’t need to change defaults:
let f = Foo(greeting: “Hello”)
and when one wishes to change one of the defaults:
let f = Foo(greeting: “Hello”, z: 4)
It would be better if one could write the struct in what I understand is the
preferred style:
struct Foo {
var greeting: String
var x = 1
var y = 2
var z = 3
}
and have the compiler generate the initializer:
init(name: String, x: Int = 1, y: Int = 2, z: Int = 3) {
self.name = name
self.x = x
self.y = y
self.z = z
}
rather than one where all the parameters that have a default value need to be
specified in the initializer if one wishes to change just one of them.
