A:

Install CocoaPods on System
Step.1 Open Terminal and enter the following command:

sudo gem install cocoapods

Create Podfile for Project
Step.2 now you need to close Xcode.
Open Terminal at project's root folder
Step.3 Next, enter below command to create podfile:

pod init

Edit podfile
Note: Make sure we will edit podfile with Xcode not TextEdit etc.
Step.4 Type this command to open the Podfile using Xcode for editing:

open -a Xcode Podfile

Step.5 update pode file as shown below screenshot, save and close.

Install lib/framework
Now we have added our required lib/framework pod command
pod 'SwiftForms'

let's go for install
Step.5 Enter the following command in Terminal and hit Enter
pod install
Result screen

Thats it!! we have done.
Open Project with pods
Now go to the project folder,we can see that CocoaPods created a new project_name.xcworkspace file and a Pods folder.
open project_name.xcworkspace with xcode
your project structure should look like
