Motivation and Context

Fixing the issue #523

Description

To avoid error on windows, adding checks cocoapods is available or not before changing swift version of cocoapods libraries.

Testing

In my local Mac,
create project and adding phonegap-plugin-push.
Checking build.
Checking the application can receive push notifications.
(by using cordova@nightly)

create project and adding phonegap-plugin-push.
Checking to skip the cocoapods specific process.
(by using cordova@8.1.0)

Awesome, super quick response @knight9999!

Just for my understanding: When is pod install and the code that you guarded in this PR run for the project then? First time being used on macOS?

[knight9999]

@janpio I simply added check_reqs.check_cocoapods() to cocoapod related function as same as the case of pod install in cordova 4.5.*.

check_reqs.check_cocoapods checks os type, cocoapods is installed or not, and cocoapods version is suitable or not. It shows appropriate warning message if necessary.

Ok, so when I add some plugin on Windows and commit, then check out on a Mac and keep working there it will still run pod install and do all the things sooner or later? No way to break the project?
