Run Swift

Example Swift scripts can be found in the “swift-0.94.1/examples/swift/tutorial ” directory. Scripts have a .swift file extension. Run the following commands to run a simple hello world application.

#cd swift-0.94.1/examples/swift/tutorial/ 
#swift hello.swift

When you run this application, it should create a file called hello.txt. If this file gets created, you have successfully ran your first Swift script!

#cd swift-0.94.1/examples/swift/tutorial/ 

#swift -help

#swift hello.swift
