CoreUsefulSDK uses new Swift Package Manager which is easiest way introduced for iOS projects since from the beginning.
From Xcode simply select File > Swift Packages > Add Package Dependency... and paste https://github.com/exozet/iOSCoreUsefulSDK to search field. You can specify rules according to your preferences and you are ready to use.
The library itself contains more than 100 extensions, which are not only as a placeholder, but really useful to contain.

All UI elements, have inspectable variable for the texts that might useful to have direct setter for localized string.
All services that are part of the UsefulSDK or any other service in the app level can use, LoggingManager service to pass messages.
The listener class from the app-level should be set into LoggingManager.delegate property, which also needs to conform LoggingDelegate protocol, and can receive messages via log:message:level:domain:source: method.
Each messages from the LoggingManager carry their level, e.g. importance.
/// minimum level of logs
case verbose
/// standard level of logs
case info
/// warning level
case warning
/// level for error logs
case error
In order to messages do more sense, also all messages carry their specified domain informations, e.g. which kind of part of the application/service responsible for it.
/// app domain
case app
/// view domain
case view
/// layout domain
case layout
/// controller domain
case controller
/// routing domain
case routing
/// service domain
case service
/// network domain
case network
/// data model domain
case model
/// cache domain
case cache
/// database domain
case db
/// input/output domain
case io
