0. INSTALL COCOAPODS
sudo gem install cocoapods

1. CHECK REPOS LOCATION, WHICH SHOULD BE EMPTY
cd ~/.cocoapods/repos/
ls

1.1 IF REPOS ALREADY EXIST, REMOVE THEM AND CLEAN INSTALL
pod repo remove master
pod setup
ls
=> 'master' should appear

2. CREATE 'TOPPROJECT' SWIFT PROJECT AND CHECK GIT VERSIONING

3. CREATE FOLDER 'MODULES' INSIDE TOPPROJECT

4. CREATE 'MODULE1' SWIFT PROJECT INSIDE MODULES FOLDER AND CHECK GIT VERSIONING

5. CREATE PODFILE
cd into topproject folder
pod init

6. FILL IN PODFILE. EXAMPLE:
# Uncomment this line to define a global platform for your project
platform :ios, '9.0'
# Uncomment this line if you're using Swift
use_frameworks!

target 'TopProject' do

pod 'Module1', :path => 'Modules/Module1'

end

7. CREATE THE MODULE1 PODSPEC
cd into module1 folder
pod spec create Module1

8. ADAPT THE MODULE1 PODSPEC
Change the location of the git url, the files included etc. Make sure to point s.source_files to Module1/*.swift

9. GO BACK TO THE TOPPROJECT FOLDER AND INSTALL
cd into topproject folder
pod install

10. ONLY USE THE .XCWORKSPACE FILE WHEN WORKING ON TOP PROJECT.

11. ADD import Module1 WHEREVER NEEDED AND CLEAN/BUILD TO REMOVE THE ERROR

12. REMEMBER TO DECLARE VARIABLES AND FUNCTIONS AS PUBLIC IN MODULE1 FILES IF YOU WANT TO ACCESS THEM

13. UPDATE THE MAIN PROJECT IN ORDER TO ACCESS NEW DEVELOPMENTS IN THE MODULES
pod update
