Setup

Required Files

Before building, you need to add the following files (not included in the repository for security):

1. GoogleService-Info.plist - Firebase configuration file

   • Obtain from Firebase Console for your project
   • Place in: MoniCrop/GoogleService-Info.plist

2. Config.swift - API credentials configuration

   • Create at: MoniCrop/Config.swift
   • Template:

   struct Config {
       static let telegramBotToken = "YOUR_BOT_TOKEN"
       static let telegramChatID = "YOUR_CHAT_ID"
   }

Build Requirements

• Xcode: 26.1+ (Build version 17B100)
• iOS Deployment Target: 16.1+
• Swift: Latest version included with Xcode

Known Issues & Workarounds

Firebase SDK Compatibility Issue (Xcode 26.1)

The project currently uses Firebase SDK 9.6.0, which has a compiler incompatibility with Xcode 26.1.

Problem: Build fails with error "An attribute list cannot appear here" in FIRFirestoreSettings.mm:33

Temporary Workaround (if build fails):

# Find the exact DerivedData path (check build logs or use this pattern)
find ~/Library/Developer/Xcode/DerivedData -name "FIRFirestoreSettings.mm" -path "*/firebase-ios-sdk/*" 2>/dev/null

# Apply the patch (replace the path with your actual DerivedData path)
sed -i.bak '33s/ABSL_CONST_INIT //' ~/Library/Developer/Xcode/DerivedData/MoniCrop-*/SourcePackages/checkouts/firebase-ios-sdk/Firestore/Source/API/FIRFirestoreSettings.mm

Important Notes:

• This patch is temporary and will be lost if you:
  • Clean the build folder (Product → Clean Build Folder)
  • Update Swift packages
  • Delete DerivedData
• You'll need to re-apply the patch if any of the above occur
• Permanent solution: Update Firebase SDK to version 10.x or 11.x (compatible with Xcode 26)
  • Requires updating Package.swift or Package.resolved
  • May require code changes for API compatibility

Building the Project

1. Open MoniCrop.xcodeproj in Xcode
2. Ensure GoogleService-Info.plist and Config.swift are added to the project
3. Select your target device or simulator (iOS 16.1+)
4. Build and run (⌘R)
5. If build fails with Firebase error, apply the workaround above
