## What it is
XCMetrics is a Swift-based tool from Spotify that collects, stores, and tracks Xcode build metrics parsed from xcactivitylog files. It includes a CLI for log ingestion, a self-hosted backend service, and a Backstage plugin for visualizing build times, warnings, and errors.

## Use cases
- track xcode build times across a team
- find which ios targets take longest to compile
- collect build warnings and errors from xcactivitylog
- monitor build performance regressions in ci
- self-host a build metrics dashboard for ios developers
- attach custom metadata like git info to xcode builds

## When to choose
- your iOS team wants visibility into Xcode build times and trends
- you want a self-hosted solution where build data stays in your infrastructure
- you need to parse xcactivitylog files and store metrics in queryable tables
- you use Backstage and want a build metrics plugin

## When to avoid
- you build for Android, web, or non-Apple platforms
- you want a hosted SaaS metrics solution with zero setup
- your project does not use Xcode or xcodebuild
