Perfect 1.0 was released on November 23, 2015, just before the Swift language became open-source,5 and draws much of its history from a programming language named Lasso, formerly part of Apple's product line.67
Version 2.0 was rolled out September 6, 20168 and brought Swift 3 compatibility and a more modular approach to the framework. The revised approach enabled developers to choose the specific features to include in Perfect-oriented projects rather than having all features bundled in by default.
