Answer 1

Swift implementation example of an UIActivityItemProvider subclass. Copy option will use only the password, other activity types will use the full share text. Should be easy to customize for different use cases. Credit to Cristopher & NickNack for their answers.

class PasswordShareItemsProvider: UIActivityItemProvider {

    private let password: String

    private var shareText: String {
        return "This is my password: " + password
    }

    init(password: String) {
        self.password = password
        // the type of the placeholder item is used to
        // display correct activity types by UIActivityControler
        super.init(placeholderItem: password)
    }

    override var item: Any {
        get {
            guard let activityType = activityType else {
                return shareText
            }

            // return desired item depending on activityType

            switch activityType {
            case .copyToPasteboard: return password
            default: return shareText
            }
        }
    }
}

Usage:

let itemProvider = PasswordShareItemsProvider(password: password)
let activityViewController = UIActivityViewController(activityItems: [itemProvider], applicationActivities: nil)
