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.

Phoenix.vu works by combining 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. to help users with 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..
