It needs to set your CocoaPod and command line tool version, in your Xcode:

Reset (Uninstall & install) cocoa pod:
Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Use keyword --pre to get the latest pre-release:

sudo gem install cocoapods --pre

---

How to set/reset Command Line Tool:
You can download latest command line tool from Apple Download Portal , if you have paid apple developer account/id.

Here are current beta and stable Xcode Tool and supporting command line tool download link. (Ensure you'are logged in using premium developer account on Apple Developer Account to access these links)

Xcode 10

• Xcode 10
  - (Command Line Tool (Xcode 10) - for macOS 10.14)
  - (Command Line Tool (Xcode 10) - for macOS 10.13)

---

Once you've latest command line tool installed in your system, set it from Xcode Menu.

I got this error when I updated my xcode version to 9.1. I fixed the error with the below command. In your terminal just add

Sudo gem install cocoapods --pre

and enter your mac password. Then try with

pod init

I have an another option to solved the issues. because of the issues happened in xcode 9.3, so i have create the project in xcode 9.2 , install the pod. and than after open the project in xcode 9.3 and start work on it.

I got the same issue with cocoapods. I have resolved this with -

rm -rf ~/.cocoapods/repos/trunk/
