Why doesn’t getAPI() show up in autocomplete despite having a default implementation in a protocol extension?

I’m working on a project in Xcode 16.2 and encountered an issue where getAPI() with a default implementation in a protocol extension doesn’t show up in autocomplete. Here’s a simplified version of the code:

import Foundation

public protocol Repository {
    func getAPI(from url: String?)
}

extension Repository {
    public func getAPI(from url: String? = "https://...") {
        getAPI(from: url)
    }
}

final class _Repository: Repository {
    func getAPI(from url: String?) {
        // Task...
    }
}

let repo: Repository = _Repository()
repo.getAPI( // Autocomplete doesn't suggest getAPI()

I’ve tried the following without success: • Clean build folder • Restart Xcode • Reindexing

Is there something wrong with the code, or is this a known issue with Xcode 16.2? I’d appreciate any insights or suggestions.
