The formalism used the concepts of fabula and syuzhet as a way to develop narrative construction or classified materials and compositions into fabula and syuzhet, respectively. The totality of microscopic events listed in causality was called a fabula, and the narrative arrangement of these motifs in an artistic way was called a syuzhet. This app is a personal project to learn the technical ingredients of SwiftUI and derive creative results. SwiftUI is a user interface toolkit that can develop applications in a declarative manner. This is a modern development method that communicates to iOS how you want the user interface to behave and finds out how users perform when interacting with the interface. In addition, SwiftUI can develop macOS, watchOS, and tvOS with the same code as well as iOS development. The most appealing thing for me personally is that it is easy to learn and that the code is concise, making it easy for beginners to understand. I hope this project will help everyone, including myself, to understand SwiftUI. The code of this project will be updated regularly. You can share and communicate with developers around the world through the Fabula app. We always look forward to the participation of developers.

About

Preloop

This app acts as a human approval layer for AI agents, intercepting risky actions and routing them for your one-tap approval. It allows AI to handle routine tasks while you maintain control over critical decisions, ensuring compliance and an audit trail.

Highlights
  • Human approval for AI actions
  • Instant notifications with context
  • One-tap approve/decline
  • Audit trail for compliance
  • Risk-based policy enforcement
  • Works with Claude and Cursor

Preloop is the human approval layer for autonomous AI agents. When your agents attempt risky actions like deployments, refunds, or data changes, Preloop intercepts the request and routes it to you for approval right on your iPhone or Apple Watch. The right people in your organization get instant notifications with full context, approve or decline with one tap, while your organization maintains a complete audit trail for compliance. Preloop enables event-driven automation through Agentic Flows - let AI agents handle routine work automatically while you control critical decisions. Setup takes 3 minutes as an MCP proxy, works with Claude and Cursor, and requires no infrastructure changes. Risk-based policies ensure only high-stakes actions need approval while low-risk operations run automatically. AI agents can't take legal or moral responsibility for their actions - Preloop ensures humans stay in control. Perfect for engineering teams, DevOps, and anyone deploying autonomous AI in production. Enterprise-ready, designed for SOC2 compliance, role-based access, and secure end-to-end encryption.
