swift access modifiers correct usage - swift

Question

Suppose I have the following struct inside a StorageService framework :
struct Post {
public let author: String
public let description: String
public let image: String
public let likes: Int
public let views: Int
}
So to access its fields from another module I mark all fields with public keyword - it's clear. But should I mark the name Post itself to be public :
public struct Post ...
I tried both ways but I see no differences (with public struct Post and struct Post).
What is the right way to follow here?

Answer 1

The access modifier of the type itself will control the accessibility of the type and hence making any properties more accessible than the type itself is useless, since you cannot access properties of a type that you don't know about.
In order to be able to use the Post type from outside your framework, you need to declare Post as public.
This makes the type itself and all of its properties accessible from outside your framework:
public struct Post {
public let author: String
public let description: String
public let image: String
public let likes: Int
public let views: Int
}
On the other hand, if you don't want to expose some specific properties/methods publicly, you can always use an accessibility modifier that is stricter than the type's modifier.
public struct Post {
public let author: String
public let image: String
public let likes: Int
let description: String // can only be accessed from inside the module
private let views: Int // can only be accessed from the Post type itself
}
