Code Standards Updates
This is primarily a non-functional change to update Astro to the latest CocoaPods versions. It also adds in SwiftLint to the project to ensure a common set of code standards is followed on the project.
Changes include:
- Some non-functional code edits to clear the SwiftLint warnings.
- There was one small interface change for two global variable definitions in KeychainAccess so they start with a lower case letter in their name per the latest Swift standards. It may break for any projects that have referenced them but its a simple fix if it happens.
