What is bootstrap-xcode-workspace?

A workflow for creating and maintaining one Xcode workspace for an Apple product containing apps, extensions, shared Swift packages, and services.

Use it to bootstrap or extend a Swift product repository, generate its root workspace and project, and organize apps, packages, services, configurations, and shared build settings.

It establishes a consistent repository layout and generated Xcode project so related Swift components stay aligned.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00036	$0.02075
Opus 5	$0.00018	$0.01038
Sonnet 5	$0.00007	$0.00415
Haiku 4.5	$0.00004	$0.00208

Security

Grade A, and why

bootstrap-xcode-workspace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bootstrap Apple Product Workspace

Purpose

Create one product repository with one root .xcworkspace and one root XcodeGen project materialized as the generated root .xcodeproj. Apps/ contains platform-specific targets in that project; Packages/ contains shared SwiftPM modules, and Services/ contains deployable SwiftPM executables. This is the entrypoint for app-first, service-first, and combined products.

Run scripts/run-workflow.fsx before creating files. It generates the root XcodeGen project, creates the workspace wrapper, initializes the first local Swift package with SwiftPM, and installs the xcode-workspace maintenance profile through repository-skills.

Required Shape

Product/
  Product.xcworkspace/
  Product.xcodeproj/                 # generated from project.yml

Ownership

project.yml owns project identity, configurations, file groups, and the included project graph.
Apps/apps-shared.yml owns common target and scheme templates.
Apps/<Target>/target.yml owns one target's platform, source roots, target-local configurations, and product dependencies.
Packages/packages-shared.yml registers local packages with XcodeGen.
Services/services-shared.yml registers deployable service packages with XcodeGen.
Each Package.swift owns its package products, targets, and dependencies.
Root Configurations/ owns project-wide settings. Apps/Apps-shared.xcconfig and target-local .xcconfig files layer app and target settings without duplicating the project baseline.
Generated .xcodeproj data is build-critical output. Edit its XcodeGen and SwiftPM sources, then regenerate; never hand-edit .pbxproj.

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
