This guide covers common issues and solutions when working with the CometChat iOS UI Kit.

---

CocoaPods Issues

Issue	Solution
”Could not find compatible versions”	Run pod install --repo-update to refresh spec repos
Pod version not found	Verify the version exists on CocoaPods
Repo clone failures	Clean repos with commands below, then retry
Build errors after pod install	Open .xcworkspace file, not .xcodeproj

Clean and Retry

rm -rf Pods Podfile.lock
pod cache clean --all
pod install --repo-update

Reset CocoaPods Completely

If repo errors persist:

rm -rf ~/.cocoapods/repos
pod setup
pod install --repo-update

Fallback to Swift Package Manager

If CocoaPods continues to fail, use SPM instead:

1. Remove Podfile and Pods folder
2. Open your .xcodeproj in Xcode
3. Go to File → Add Package Dependencies
4. Add https://github.com/cometchat/cometchat-uikit-ios with version 5.1.9
5. Add https://github.com/cometchat/chat-sdk-ios with version 4.1.0

Initialization Issues

Issue	Solution
SDK not initialized	Call CometChat.init() before any UI Kit operations
User not logged in	Ensure CometChat.login() completes successfully before showing UI
UIKit not initialized	Call CometChatUIKit.init() after SDK init and before using components
