Install Homebrew and CocoaPods in xcode 14

I have an old MacBook (Early 2015) running macOS Monterey 12.7.6.

When I try to install CocoaPods via the command line, I get the following error:

securerandom requires Ruby version >= 3.1.0. The current Ruby version is 2.6.10.210.

I cannot update Ruby using gem update --system because macOS does not allow it.

So, I decided to use Homebrew to install CocoaPods instead.

Installing Homebrew

First, I checked if Homebrew was installed by running:

brew -v

However, this returned an error:

-bash: brew: command not found

To install Homebrew, I used the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

During installation, I had to enter my password a few times.

Once the installation was complete, I verified it by running:

brew -v

The output confirmed that Homebrew was installed:

Homebrew 4.4.20

Installing CocoaPods

Now that Homebrew is installed, I was able to install CocoaPods using:

brew install cocoapods

Additionally, I was able to update Ruby and then use Ruby to install CocoaPods.
