How to check version of a CocoaPods framework
The Podfile.lock keeps track of the resolved versions of each Pod installed. If you want to double check that FlurrySDK is using 4.2.3, check that file.
Note: You should not edit this file. It is auto-generated when you run pod install or pod update
To check version of cocoapods from terminal:
For Sudoless:
gem which cocoapods
For Sudo:
sudo gem which cocoapods
Also note: If you want to edit podfile or podfile.lock don't edit it in editors. Open only with XCode.
