Swift Compilation with Sublime Text 3 on macOS

Adding Swift Build System

Open Sublime Text 3 Go To Preferences > Browse Packages... Create a folder "SwiftBuilder" inside Packages directory. Add a file named Swift.sublime-build inside SwiftBuilder directory. Copy the following script in Swift.sublime-build file.

{
 	"shell_cmd": "xcrun swift \"$file\"",
 	"file_regex": "^(..[^:]*):([0-9]+):?([0-9]+)?:? (.*)$",
 	"working_dir": "${file_path}",
 	"selector": "source.swift",
}

Go to Preferences > Key Bindings-User and add the following script to it.

{
	"keys": ["super+b"],
	"command": "build",
	"context": [
	    { "key": "selector", "operator": "equal", "operand": "source.swift" }
	    ], 
	    
	    "args": {
	    "build_system": "Packages/SwiftBuilder/Swift.sublime-build",
	    "variant": "Build"
	    }
}

You are ready to run Swift scripts from Sublime Text 3 now.

Testing the Swift Build System

1. Create a file A.swift containing a single line println("Hello, Swift!").
2. Press command + b and you'll be able to see the output.
3. If you are unable to see the output, go to Tools > Build Systems and change it from Automatic to Swift, and you should be able to run Swift in ST3.
