protocols are leaking implementation details

[godbout]

by using Protocols to define a bunch of common implementation, the properties of those protocols are leaking. i want to have them as private but it's not possible as currently in Swift (5.4) protocol properties can't have their access control specified. it just follows the one of the protocol itself.

not sure how to handle this yet. i'd like to avoid duplicating methods around different struct/class but i also want to avoid open unnecessary implementation details.

e.g.:

• AlfredWorkflowScriptFilter/Sources/AlfredWorkflowScriptFilter/Protocols/HasSubtitle.swift

  Line 2 in b62f879

  var subtitle: String? { get set }

• AlfredWorkflowScriptFilter/Sources/AlfredWorkflowScriptFilter/Core/Item.swift

  Line 16 in b62f879

  public var subtitle: String?
