Has anyone gotten Claude Fable 5 working inside Xcode’s agentic coding tools?

Xcode’s built-in AI tooling lets you add third-party model providers, but I haven’t found a clean way to point it at Claude Fable 5 yet. Has anyone gotten it working — either through the Anthropic API endpoint directly, a proxy, or an MCP setup? Curious if it’s a model-string issue or if Xcode just doesn’t support it yet. Would love to hear any working configs.

My Second App

Shipped my second iOS app — calc318, a SwiftUI app that solves ACI 318-19 (structural engineering) equations live, with interactive sensitivity graphs built on Swift Charts.

Built for a pretty narrow audience (structural engineers myself included), which has been its own lesson in marketing something niche.
