+%description
+Swift is a general-purpose programming language built using
+a modern approach to safety, performance, and software design
+patterns.
+
+The goal of the Swift project is to create the best available
+language for uses ranging from systems programming, to mobile
+and desktop apps, scaling up to cloud services. Most
+importantly, Swift is designed to make writing and maintaining
+correct programs easier for the developer.
