Swiftlint config and linter corrections with minor improvements.

In this PR I have updated the .swiftlint.yml file to look at the correct new folder (From DEV -> To DEV-Simple) also added to the .swiftlint.yml to ignore the Carthage directory, also for the ones using Xcode the reporter has been change from JSON to Xcode. to able to see the warnings.

With swiftLint working again a did a formatting with the linter recommendations, with this preliminary setup with can discuss the use of custom rules for styling in the development of the app.

Also I did a change for some memory leaks with strong self references in closures.

Any questions I'm glad to respond.
