swift-protocol-default-args-resolution

To resolve the default argument error in Swift protocols, remove the default value from the protocol method signature and add a convenience overload with the default parameters in a protocol extension.

Swift protocol signatures define requirements without implementation logic, so default arguments are unsupported. You must move default values to convenience overloads within a protocol extension to provide the fallback behavior.

To correct file-level access control issues in Swift, change the `private` modifier to `fileprivate` so that other types within the same source file can access the restricted properties or methods.

The best approach to unwrap optional dates for formatters in Swift is using conditional binding or optional chaining to safely extract the date value before passing it to the formatter method.

Implement cursor-based pagination by passing a cursor token between your iOS client and backend, fetching the next data batch using the token, and updating the client query until the cursor returns nil.

Yes, Swift protocol extensions allow you to provide default implementations by adding convenience overloads, which satisfies the protocol requirement while offering default parameter values to conforming types.
