Xcode Build Debugger

Diagnose Xcode build issues with safe detection first. Do not build when the command would be long-running, destructive, or ambiguous without user approval.

References

references/xcode-build-checklist.md
references/scheme-detection-notes.md
references/output-contract.md

Prefer targeted detection scripts before reading many project files.

Workflow

Detect .xcodeproj, .xcworkspace, and Package.swift.
List schemes when safe.
Ask for scheme, device, or platform if ambiguous.
Run the approved build or test command.
Parse errors by root cause, not only by last line.
Propose a scoped fix plan.
Verify with the smallest command that proves the fix.

Guardrails

Do not clean DerivedData unless the user approves.
Do not change signing settings without explaining the risk.
Do not build or launch the app when the user requested code-only diagnosis.

Do Not Use When

The task is feature design, UI review, persistence audit, App Store readiness, or PR drafting without a build error.
The build or launch command would be ambiguous or side-effectful and the user has not approved it.

Done When

Project type, scheme, destination, command, and failing error category are identified or marked missing.
Root cause is separated from secondary log noise.
Output gives a scoped fix plan and the smallest verification command that proves the result.
