Swift Installer is a personalization application by Beach Road IT. The application is an extra package for Swift Substratum Theme where it includes a custom installer, color engine, and more themes. Users can define the standardized hex colors for the infinitive dark background and accents. This application works with 186 applications so that users can change their colors. It supports Samsung S8, Note 8, S9, Note9, as well as other Samsung Oreo devices. Users who wish to mix themes have to use the Swift Substratum Theme instead. The application can be used among Swift themes only. On the other hand, it has an update system that skips reinstalling of all overlays every time an update is available.
