If you're working on a React Native project and trying to manage iOS dependencies using CocoaPods, you might encounter various issues during the installation process. Recently, I faced an error when running pod install and resolved it by ensuring the correct setup of Xcode and Ruby on my system. This blog post details the error and the steps I took to resolve it.
Error Log
Here's the error log I encountered when attempting to run pod install:

Solution
To resolve the issue, I followed these steps:
Install Xcode
Since the error indicated that the SDK could not be located, the primary solution was to install Xcode, which includes the necessary SDKs and tools.
Install Xcode from the App Store:
- Open the App Store on your Mac.
- Search for "Xcode."
- Click "Get" and then "Install."
Install Xcode Command Line Tools, Open Terminal and run:
xcode-select --install
Set the command line tools path:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
Agree to the Xcode License:
sudo xcodebuild -license accept
Verify Installation
- Open Xcode and ensure any additional components are installed.
- Ensure Xcode Command Line Tools are set correctly:
- Run the following command in Terminal to verify the path:
xcode-select --print-path
It should output /Applications/Xcode.app/Contents/Developer.
- Verify that the necessary SDKs are available:
xcodebuild -showsdks
Following above steps I was able to resolve the issues and successfully install the necessary pod dependencies for my React Native project.
