Is there a way I can use a CocoaPod written in Objective-C in my Swift project using swift?
Do I just make a bridging header? And if so, can I access the objects, classes, and fields defined by the libraries in the CocoaPod in Swift?

Basic answer to your question is Yes, you can use objective-c code built with CocoaPods.
More important question is "How to use such libs?"
Answer on this question depends on use_frameworks! flag in your Podfile:
Let's imagine that you want use Objective-C pod with name CoolObjectiveCLib.
If your pod file uses use_frameworks! flag:
// Podfile
use_frameworks!
pod 'CoolObjectiveCLib'
Then you don't need add any bridge header files.
Everything that you need is import framework in Swift source file:
// MyClass.swift
import CoolObjectiveCLib
Now you can use all classes that are presented in lib.
If your pod file doesn't use use_frameworks! flag:
// Podfile
pod 'CoolObjectiveCLib'
Then you need create bridging header file and import there all necessary Objective-C headers:
// MyApp-Bridging-Header
#import "CoolObjectiveCLib.h"
Now you can use all classes that are defined in imported headers.

how to access swift classes from inside pod .m files (in case i want to customise these pods) ?

I had use_frameworks uncommented in my swift project's podfile and wanted to use the Toast pod, which actually is an objective-c category. By simply writing import UIView+Toast gave me compilation error: Consecutive statements on a line must be separated by ';'

@ChanchalRaj is
UIView+Toast name for your pod? If not try to use import framework which name matches to your pod name.

I have used same code to use objc code to swift file but it gives me error no such a module "POD NAME" , Do I need to set any other flag

If you are facing issues with use_frameworks!, it might be because the import statements are not written in the correct format. e.g. if the podFile contains
pod 'iOS-Echarts', then imports shall happen like following: Swift file: import iOS_Echarts Objective-C file: #import <iOS_Echarts/iOS-Echarts.h> |
In podFile use the flag use_frameworks!
Inside Xcode in the Pod folder structure in the dependency, you add xxxxxxx-umbrella.h in Support Files.
In your {PROJECT_NAME}-Bridging-Header.h use:
#import "xxxxxxx/xxxxxxx-umbrella.h"
It works for me.

You just need a bridging header and import there what you need.

AND don't forget to add Bridging Header file name to Target -> Build Settings -> Objective-C Bridging Header
