How to automatically create an initializer for a Swift class?
2 answers
I have a struct:
struct MenuSection {
var title: String?
var items: [MenuItem] =
}
I can use the automatically generated initializer as follows:
MenuSection(title: nil, items: items)
When I change the struct to be a class, I have to write a boilerplate initializer to suppress warnings:
class MenuSection {
var title: String?
var items: [MenuItem] =
init(title: String? = nil, items: [MenuItem] = ) {
self.title = title
self.items = items
}
}
Can I force compiler to synthesize initializer in class as in struct?

Short answer: No. Only structs have a default memberwise initializer.
