+# CodeQL Configuration
+
+This directory contains the CodeQL security scanning workflow for the Budget-AI project.
+
+## Workflow Overview
+
+The `codeql.yml` workflow performs automated security analysis on three languages:
+
+- **Python** - Backend API (`backend/`) and background worker (`worker/`)
+- **Swift** - iOS application (`BudgetAI/`, `BudgetAITests/`, `BudgetAIUITests/`, `testapp/`)
+- **JavaScript/TypeScript** - Next.js web frontend (`web/`)
+
+## Triggers
+
+- **Push/Pull Requests**: Runs on all pushes and PRs to `main` and `develop` branches
+- **Weekly Scan**: Scheduled to run every Sunday at midnight UTC
+
+## Query Suites
+
+The workflow uses two comprehensive query suites:
+- `security-extended` - Extended security queries
+- `security-and-quality` - Combined security and code quality checks
+
+## Important Setup Note
+
+⚠️ **GitHub Default CodeQL Setup Conflict**
+
+If you see errors like:
+```
+CodeQL analyses from advanced configurations cannot be processed when the default setup is enabled
+```
+
+This means the repository has GitHub's default CodeQL setup enabled. To use this custom workflow:
+
+1. Go to repository **Settings** → **Security** → **Code scanning**
+2. Find "CodeQL analysis" with "Default" label
+3. Click the **"..."** menu → **"Disable CodeQL"** or **"Switch to advanced"**
+4. The custom workflow will then work without conflicts
+
+## Build Configuration
+
+- **Python & JavaScript/TypeScript**: No build required (interpreted languages)
+- **Swift**: Manual build using `xcodebuild` with:
+  - Generic iOS Simulator destination for compatibility
+  - Code signing disabled (`CODE_SIGNING_ALLOWED=NO`)
+  - 360-minute timeout to accommodate build time
+
+## Benefits
+
+✅ Comprehensive multi-language security scanning  
+✅ Detects vulnerabilities across entire codebase  
+✅ Automated weekly security audits  
+✅ Runs on every code change  
+✅ Uses advanced security query suites  
+
+## Troubleshooting
+
+### Swift Build Timeout
+If the Swift build times out, consider:
+- Using a faster macOS runner
+- Reducing the scope of files to analyze
+- Caching build dependencies
+
+### Analysis Failures
+Check the Actions tab for detailed logs. Common issues:
+- Build errors in Swift code
+- Syntax errors in source files
+- Configuration conflicts with default setup

+# CodeQL Setup Instructions
+
+## ⚠️ IMPORTANT: Action Required by Repository Owner
+
+The CodeQL workflow has been successfully configured, but **it cannot run until the repository's default CodeQL setup is disabled**. This is a one-time repository configuration change.
+
+## Current Status
+
+✅ Custom CodeQL workflow configured for Python, Swift, and JavaScript/TypeScript  
+✅ Workflow file is valid and properly configured  
+❌ **Blocked**: Repository has default CodeQL setup enabled, causing conflicts
+
+## Error Message
+
+When the workflow runs, you'll see:
+```
+CodeQL analyses from advanced configurations cannot be processed when the default setup is enabled
+```
+
+## Solution (Repository Owner Must Complete)
+
+### Step 1: Disable Default CodeQL Setup
+
+1. Go to your repository on GitHub.com
+2. Click **Settings** tab
+3. In the left sidebar, click **Security** → **Code scanning**
+4. Find "CodeQL analysis" with a "Default" label
+5. Click the **"..."** menu button next to it
+6. Select **"Switch to advanced"** or **"Disable CodeQL"**
+7. Confirm the action
+
+### Step 2: Verify the Custom Workflow Works
+
+After disabling the default setup:
+1. The existing pull request checks will automatically re-run
+2. Or you can manually re-run the failed workflow from the Actions tab
+3. All three language analyses should complete successfully
+
+## What This Workflow Provides
+
+Once enabled, you get:
+
+- **Comprehensive Security Scanning**
+  - Python code (backend + worker)
+  - Swift code (iOS app + tests)
+  - JavaScript/TypeScript code (web frontend)
+
+- **Advanced Query Suites**
+  - `security-extended` - Extended security analysis
+  - `security-and-quality` - Code quality + security checks
+
+- **Automated Scanning**
+  - Every push to main/develop branches
+  - Every pull request
+  - Weekly scheduled scans (Sunday midnight UTC)
+
+## Alternative Option
+
+If you prefer to use GitHub's default CodeQL setup instead:
+1. Keep the default setup enabled
+2. Delete this custom workflow file (`.github/workflows/codeql.yml`)
+3. The default setup will handle all languages automatically
+
+**Note**: The custom workflow provides more control over query suites, build configuration, and path filtering.
+
+## Need Help?
+
+If you encounter issues after following these steps, check:
+- Actions tab for detailed error logs
+- `.github/workflows/README.md` for troubleshooting guide
+- GitHub's CodeQL documentation: https://docs.github.com/en/code-security/code-scanning
+
+## Questions?
+
+- **Q**: Why can't both run at the same time?
+  - **A**: GitHub doesn't allow custom advanced configurations when default setup is active to avoid duplicate analysis and conflicts.
+
+- **Q**: Which setup is better?
+  - **A**: Default setup is easier but less customizable. Advanced (this workflow) gives full control over queries, build process, and scanning options.
+
+- **Q**: Will this affect my security?
+  - **A**: No. After switching, you'll have the same (or better) security scanning with the custom workflow.

-# CodeQL Setup Instructions
+# ⚠️ CRITICAL: CodeQL Setup Instructions
 
-## ⚠️ IMPORTANT: Action Required by Repository Owner
+## 🚨 ACTION REQUIRED - Repository Owner Must Complete This Step
 
-The CodeQL workflow has been successfully configured, but **it cannot run until the repository's default CodeQL setup is disabled**. This is a one-time repository configuration change.
+**The CodeQL workflow CANNOT run until you disable the default CodeQL setup.**
 
-## Current Status
+### Current Error
 
-✅ Custom CodeQL workflow configured for Python, Swift, and JavaScript/TypeScript  
-✅ Workflow file is valid and properly configured  
-❌ **Blocked**: Repository has default CodeQL setup enabled, causing conflicts
-
-## Error Message
-
-When the workflow runs, you'll see:
 ```
-CodeQL analyses from advanced configurations cannot be processed when the default setup is enabled
+Code Scanning could not process the submitted SARIF file:
+CodeQL analyses from advanced configurations cannot be processed 
+when the default setup is enabled
 ```
 
-## Solution (Repository Owner Must Complete)
+### What This Means
+
+Your repository has GitHub's **default CodeQL setup** enabled. This setting **completely blocks** any custom CodeQL workflows from working. The workflow configuration is correct, but GitHub will not process the results until you change this setting.
 
-### Step 1: Disable Default CodeQL Setup
+---
+
+## 🔧 How to Fix (5 Minutes)
+
+### Step 1: Navigate to Code Scanning Settings
 
 1. Go to your repository on GitHub.com
-2. Click **Settings** tab
-3. In the left sidebar, click **Security** → **Code scanning**
-4. Find "CodeQL analysis" with a "Default" label
-5. Click the **"..."** menu button next to it
-6. Select **"Switch to advanced"** or **"Disable CodeQL"**
-7. Confirm the action
+2. Click the **Settings** tab (top right)
+3. In the left sidebar, scroll down to **Security**
+4. Click **Code security and analysis**
+5. Scroll to the **Code scanning** section
+
+### Step 2: Disable Default Setup
+
+You'll see "CodeQL analysis" with a **"Default"** badge or label:
+
+1. Click the **"..."** menu (three dots) next to "CodeQL analysis"
+2. You'll see options:
+   - **"Switch to advanced"** (recommended) - Use this if you want to keep using CodeQL
+   - **"Disable CodeQL"** - Use this if you want to completely disable it
+
+3. Click **"Switch to advanced"**
+4. Confirm the action
+
+### Step 3: Verify It Works
+
+After switching to advanced:
+- The PR checks will automatically re-run
+- Or you can manually trigger them from the Actions tab
+- All three language analyses (Python, Swift, JavaScript/TypeScript) should complete successfully
+
+---
+
+## ✅ What Happens After You Fix This
+
+Once you complete the steps above:
+
+✅ **Python analysis** will scan your backend (`backend/`) and worker (`worker/`)  
+✅ **Swift analysis** will scan your iOS app and tests  
+✅ **JavaScript/TypeScript analysis** will scan your web frontend (`web/`)  
+✅ **Automated security scans** will run on every push and PR  
+✅ **Weekly security audits** will run automatically  
+
+---
+
+## 🤔 Why Can't Both Run?
+
+GitHub doesn't allow default and advanced (custom) CodeQL setups to run simultaneously because:
+- It would create duplicate analyses
+- Results would conflict
+- It would waste CI minutes
+
+You must choose one or the other.
+
+---
+
+## 📊 What You Get with This Custom Workflow
+
+The custom workflow (already configured) provides:
+
+### Advanced Query Suites
+- `security-extended` - Extended security vulnerability detection
+- `security-and-quality` - Code quality + security analysis
+
+### Multi-Language Coverage
+- **Python**: Backend API + background worker
+- **Swift**: iOS app + all test suites  
+- **JavaScript/TypeScript**: Next.js web frontend
 
-### Step 2: Verify the Custom Workflow Works
+### Automated Triggers
+- Every push to `main` or `develop` branches
+- Every pull request
+- Weekly scheduled scans (Sunday midnight UTC)
 
-After disabling the default setup:
-1. The existing pull request checks will automatically re-run
-2. Or you can manually re-run the failed workflow from the Actions tab
-3. All three language analyses should complete successfully
+### Custom Build Configuration
+- Optimized Swift builds for CI

+## ❓ Frequently Asked Questions
 
-- **Comprehensive Security Scanning**
-  - Python code (backend + worker)
-  - Swift code (iOS app + tests)
-  - JavaScript/TypeScript code (web frontend)
+### Q: Will this affect my repository's security?
+**A**: No! After switching, you'll have the same (or better) security coverage with the custom workflow.
 
-- **Advanced Query Suites**
-  - `security-extended` - Extended security analysis
-  - `security-and-quality` - Code quality + security checks
+### Q: Can I switch back to default setup later?
+**A**: Yes, but you'll need to delete the custom workflow file first.
 
-- **Automated Scanning**
-  - Every push to main/develop branches
-  - Every pull request
-  - Weekly scheduled scans (Sunday midnight UTC)
+### Q: What if I want to use the default setup instead?
+**A**: Delete the `.github/workflows/codeql.yml` file and keep the default setup enabled.
 
-## Alternative Option
+### Q: How do I know if I've done it correctly?
+**A**: After switching to advanced, go to the Actions tab and look for the "CodeQL Analysis" workflow running. It should complete without the configuration error.
 
-If you prefer to use GitHub's default CodeQL setup instead:
-1. Keep the default setup enabled
-2. Delete this custom workflow file (`.github/workflows/codeql.yml`)
-3. The default setup will handle all languages automatically
+### Q: Who can make this change?
+**A**: Only repository owners or administrators with "Write" or "Admin" permissions can change code scanning settings.
 
-**Note**: The custom workflow provides more control over query suites, build configuration, and path filtering.

-## Need Help?
+## 🆘 Still Having Issues?
 
-If you encounter issues after following these steps, check:
-- Actions tab for detailed error logs
-- `.github/workflows/README.md` for troubleshooting guide
-- GitHub's CodeQL documentation: https://docs.github.com/en/code-security/code-scanning
+If you've completed the steps above and still see errors:
 
-## Questions?
+1. **Check the Actions tab** for detailed error logs
+2. **Review** `.github/workflows/README.md` for troubleshooting
+3. **Verify** you have the correct permissions (Settings tab should be visible)
+4. **Wait** a few minutes after changing settings for GitHub to sync
 
-- **Q**: Why can't both run at the same time?
-  - **A**: GitHub doesn't allow custom advanced configurations when default setup is active to avoid duplicate analysis and conflicts.
+---
 
-- **Q**: Which setup is better?
-  - **A**: Default setup is easier but less customizable. Advanced (this workflow) gives full control over queries, build process, and scanning options.

-- **Q**: Will this affect my security?
-  - **A**: No. After switching, you'll have the same (or better) security scanning with the custom workflow.

+# ⚠️ ATTENTION: CodeQL Workflow Requires Your Action
+
+## The Error You're Seeing
+
+```
+CodeQL analyses from advanced configurations cannot be processed 
+when the default setup is enabled
+```
+
+## What This Means
+
+**YOU** (the repository owner) need to change a setting in your repository. I cannot do this for you because it's a repository configuration, not code.
+
+## How to Fix (2 Minutes)
+
+### Option 1: Use the Custom Workflow (Recommended)
+
+1. Open your repository on GitHub.com
+2. Click **Settings** → **Security** → **Code security and analysis**
+3. Find "CodeQL analysis" with a **"Default"** label
+4. Click the **"..."** menu → **"Switch to advanced"**
+5. Done! The workflow will now work.
+
+📖 **See `.github/CODEQL_SETUP.md` for detailed step-by-step instructions**
+
+### Option 2: Use GitHub's Default Setup
+
+If you don't want the custom workflow:
+1. Delete `.github/workflows/codeql.yml`
+2. Keep the default setup enabled
+3. Done!
+
+## Why This Happens
+
+- GitHub doesn't allow **both** default setup **and** custom workflows
+- You must choose one or the other
+- This is intentional to avoid duplicate analyses
+
+## Current Status
+
+| Item | Status |
+|------|--------|
+| Workflow code | ✅ Correct and ready |
+| Configuration | ✅ Valid |
+| **Your action needed** | ❌ **Repository setting** |
+
+**The workflow is perfectly configured. It just can't run until you change the repository setting.**
