I searched and got answers on using CocoaPods but really i couldn't manage to use it because i didn't what they mean
1- Install CocoaPods 0.39.0 or later. -> i did install it using sudo command
"I stopped here, didn't know what to do"
2- In your Podfile, add use_frameworks! and pod 'RealmSwift' to your main and test targets.
3- From the command line, run pod install.
4- Use the .xcworkspace file generated by CocoaPods to work on your project!
sorry my question looks bad but it is my first time to ask a question here :)
