I am trying to use CoreStore in my project, I found that all fields in the Demo are declared with let , and there seems to be no way to set access controls, i.e. read-only variables.

A very common usage scenario is:

final class User: CoreStoreObject {

  // Cannot be modified after initialization.
  let identifier = Value.Requited<String>("identifier", initial: "")

  // Can only be modified internally.
  private(set) var name = Value.Optional<String>("name")

  func update(name: String?, completion: Completion?) {
    // Perform a network request...
    self.name = name
  }
}

In the above example, I want to only allow name to be modified inside the class, the external can only be read.

What should I do?

Make the property private and expose it through a computed property:

final class User: CoreStoreObject {
  var name: String? {
       return _name.value
  }
  private let _name = Value.Optional<String>("name")
}
