Concise monthly summary for 2025-12 focusing on business value and technical achievements across getsentry/sentry-docs and getsentry/sentry-cocoa. Highlights include: (1) Documentation enhancements for iOS SDK: consolidation of updates, removal of the in-app-exclude parameter, migration guidance from CocoaPods to Swift Package Manager (SPM), and introduction of Auto-Update SDK documentation for internal builds; clarifications of cold/warm start terminology. (2) iOS-specific documentation support for the new Auto-Update SDK flow, ensuring docs align with the latest release and internal build processes. (3) MetricKit integration improvements in the Cocoa repository: simplified models, improved stacktrace parsing, migration of components to Swift, and fixes for race conditions in the delegate, improving reliability of telemetry data. (4) Swift modernization of core Cocoa components: conversion of critical modules from Objective-C to Swift to improve type safety, maintainability, and interoperability. (5) Logging, serialization, and internals enhancements: performance improvements in log encoding paths, removal of redundant decodable conformance and loops, and strengthening SDK setup and tests for robustness. Overall, these efforts deliver clearer documentation for developers and users, more reliable metrics collection, and a leaner, more maintainable codebase with faster onboarding for contributors.
