[SPM] Fix unfound file warnings from swift build

[paulb777]

Fix #16012
The Pull Request #16041 in the firebase-ios-sdk repository aims to fix "file not found" warnings that occur during Swift Package Manager (SPM) builds.

Key Changes

• Fixing Build Warnings: The primary goal is to resolve warnings triggered by swift build related to missing or incorrectly referenced files.

• Package.swift Updates: Modifications were made to the Package.swift file to refine how paths and exclusions are handled. This includes:

  • Updating paths for FirebaseCrashlyticsSwift.
  • Cleaning up trailing slashes in path strings (e.g., changing "ProtoSupport/" to "ProtoSupport").
  • Consolidating source and exclusion lists to ensure the build system correctly identifies the intended files.

• Documentation Consolidation: A significant number of small AGENTS.md files scattered throughout the FirebaseAI directory were deleted and replaced with a single, comprehensive FirebaseAI/AGENTS.md. This new file serves as a "Codebase Map" to help AI agents navigate the SDK structure.

• Changelog Updates: The CHANGELOG.md files for both Crashlytics and FirebaseAI were updated to reflect these fixes.

Statistics

• Files changed: 19
• Additions: 187
• Deletions: 286

In short, it’s a cleanup PR focused on improving SPM reliability and streamlining internal documentation for better AI-assisted development.

Code Review

This pull request resolves "unfound file" warnings during swift build by refining path definitions and exclusions within Package.swift. Key changes include adding a comprehensive exclusion list for the FirebaseAI target and standardizing directory paths by removing trailing slashes. Review feedback identifies a duplicate UnitTests entry in the Crashlytics exclusion list and suggests further path normalization for consistency, specifically removing a trailing slash from the FirebaseCrashlyticsSwift path and simplifying the source path from ./ to ..

Code Review

This pull request consolidates AI agent documentation for the FirebaseAI module into a single AGENTS.md file and resolves swift build warnings by refining path specifications in Package.swift. Specifically, trailing slashes were removed from directory paths, and the FirebaseCrashlyticsSwift target path was updated. Feedback suggests further simplifying the FirebaseCrashlyticsSwift target by removing the redundant sources parameter, as the path already points to the source directory.

Code Review

This pull request addresses unfound file warnings from 'swift build' by updating the Package.swift configuration and cleaning up the project structure. It also adds a new codebase map for FirebaseAI and updates the changelogs. The reviewer requested verification of the path 'Crashlytics/Crashlytics/Rollouts' in Package.swift, as it appears potentially redundant.
