Lightning Fast

Typical project scan completes in under 2 seconds. No waiting, no build cycles, instant feedback on configuration issues.

Evidence-Based

Every diagnosis includes concrete proof from your project files with exact locations, current vs. expected values, and cross-file references.

Safe by Design

Read-only scanning never modifies your project. All fixes require explicit consent with rollback support. No network, no telemetry, fully offline.

9 Comprehensive Diagnostic Checks

Specialized validation for the most common Xcode configuration pitfalls.

01

Watch Companion Mismatch

Validates bundle ID relationships between watch apps and iOS companions.

02

CloudKit Entitlement

Ensures CloudKit container identifiers match between capabilities and entitlements.

03

Widget Bundle Identifier

Verifies widget extension bundle IDs follow required patterns.

04

WidgetKit Framework

Confirms WidgetKit.framework is properly linked for widget targets.

05

Signing Consistency

Detects code signing mismatches across targets and configurations.

06

Bundle Identifier Collision

Prevents duplicate bundle IDs within a single project.

07

App Group Consistency

Validates app group configurations across related targets.

08

Deployment Target Mismatch

Ensures deployment targets are properly aligned across targets.

09

Entitlement Without Capability

Finds entitlements defined without matching Xcode capabilities.

Design Principles

Deterministic

No guessing, no heuristics, only verifiable facts from your project files.

Evidence-Based

Every diagnosis includes proof with exact file locations and values.

Fast

Sub-2-second scans for typical projects with smart, lazy file loading.

Safe

Read-only scanning; fixes require explicit consent with rollback support.

Offline-First

No network dependencies, cloud services, or telemetry. Fully local.

Transparent

Clear explanations of what breaks and why it matters for your app.

No AI

Reliable, repeatable validation without unpredictability or black boxes.

No Portal Access

Respects your security; never touches Apple Developer accounts.

Why Xcode Doctor?

Xcode projects are complex with hundreds of configuration settings spread across multiple files (.pbxproj, Info.plist, entitlements, schemes). Common issues often manifest late—during archiving, TestFlight upload, or worse, in production.

CloudKit containers configured in entitlements but missing the required capability

Watch companion apps with mismatched bundle identifiers

Widget extensions with incorrect bundle ID patterns or missing frameworks

Code signing inconsistencies between targets

Xcode Doctor catches these issues early with deterministic, evidence-based scanning—before they cost you hours of debugging or delay your releases.

Common Questions

Does Xcode Doctor modify my project files?

No, not in read-only scan mode. All scans are completely safe. Fix application requires explicit user consent and supports rollback.

Does it require internet connectivity?

No. Xcode Doctor works entirely offline with no network dependencies, cloud services, or telemetry.

How is this different from Xcode's built-in validation?

Xcode Doctor catches configuration issues *before* you build, with more comprehensive cross-file validation and detailed evidence. It performs deeper analysis across Info.plist, entitlements, and build settings that Xcode doesn't check until build or archive time.

Can it fix issues automatically?

Yes, for safe operations. All fixes require explicit confirmation and support rollback. The app clearly indicates which fixes can be automated and which require manual intervention.

Does it send telemetry or analytics?

No. Zero data collection, zero cloud services, zero external communication. Xcode Doctor respects your privacy and works entirely offline.
