An AI coding agent for Xcode that writes Swift, runs builds, fixes build errors automatically and shows diffs, while source code stays on your Mac.

Automatic Build Error Repair: Runs the Xcode build, identifies compile errors, applies fixes and re-validates the result through an iterative repair loop until the project compiles.
Side-by-Side Xcode Workflow: Sits next to Xcode with real-time build monitoring, diff review and inline approvals so you never leave the IDE to consult an AI.
Codebase Understanding Before Coding: Reads and understands the project structure before writing anything, so generated Swift fits the existing architecture rather than being pasted in blind.
Diff Review Before Apply: Every proposed change is shown as a reviewable diff that you approve or reject, so the agent never silently rewrites files.
Persistent Project Memory: Retains its understanding of your project across development sessions instead of relearning the codebase every time you start.
Local Source Code Storage: Source code stays on the Mac under a privacy-first architecture, with only inference context sent off-device.
Swift and SwiftUI Native: Built for the Apple ecosystem with deep Swift and SwiftUI understanding and native Xcode workflows rather than generic language support.
Usage-Based Credits: Pay per AI request with exact credit costs shown before and after every task, with no seats or subscription commitment.

Feature Implementation: Describe a new screen or capability in plain English and have the agent write the Swift, build it and hand back a reviewable diff.
Build Failure Triage: Hand a failing Xcode build to the agent and let it iterate through compile errors until the project builds again.
Legacy UIKit Modernization: Refactor older Apple codebases toward SwiftUI and current Swift idioms with the agent validating each step against a real build.
Privacy-Constrained Teams: Adopt an AI coding agent at organizations that cannot upload source to the cloud, since the code stays on the developer's Mac.
Occasional Contract Work: Pay only for the requests you actually make, which suits indie and contract Apple developers who do not want a monthly seat.
Code Change Auditing: Use the mandatory diff review step to keep tight control over exactly how AI modifies an app before release.
