Swift Practice Environment

Make environment for Swift Practice

I need to learn swift again, and of course XCode project is one of option to use Swift practice. But, I want to use simple env just try swift programming

I have some options to set up Swift Practice Env

• Playground
• Commandline and Text editor
• REPL
• Linux Docker with REPL

Playground

Playground is simple way to test swift program

This is XCode tool.

Commandline and Text editor

Create file and compile and run

hello.swift

import Foundation

print("Hello")

Compile codes (with swiftc command)

swiftc hello.swift

Run execution file

./hello

If you want to run without compile

swift hello.swift

REPL

This is dialog base programming environment like Iron Python

To start REPL

swift

Welcome to Apple Swift version 5.1.3 (swiftlang-1100.0.282.1 clang-1100.0.33.15).

Type :help for assistance.

Linux Docker with REPL

We can create isolated environment with Linux docker.

Swift supports Linux(Ubuntu), too. Docker image is provided by many people

This is an example (swift-docker)

docker pull swift
docker run --security-opt seccomp=unconfined -it swift

You can use swift REPL on linux
