Ubuntu on Swift Development Learning 1

Learning Purpose: Learn swift by building a practical process for Web applications. Use the perfect framework to build a Web application (perfect is a web framework for swift).

This article introduces environment construction

Best practice of Swift (TODO ...)

1. Install dependencies

[Email protected]:sudoinstall clang libicu-dev

2. Download the swift-3.0.1-preview-1-ubuntu16.04 installation package from the https://swift.org/download/website, my operating system is Kbuntu16.04

Put it in/home/{user}/downloads/.

Unzip the file using the following command

[Email protected]:tar -xzf swift-3.0. 1-preview-1-ubuntu16. . tar. gz

Automatically generate the swift-3.0.1-preview-1-ubuntu16.04 folder in the current directory after decompression

3. Setting the environment variables for Swift

[Email protected]:VI ~/.BASHRC

Add this line at the end of the file (Vim editor, press i key to enter edit mode)

Export Path=/home/{user}/downloads/swift-3.0.1-preview-1-ubuntu16.04/usr/bin:"${path}" 

{User} Here is the placeholder, is usually your current login using the user name, specifically, the previous section of the/home/{user}/downloads/, is your installation package storage path, according to the actual installation completed.

Press the ESC key to exit edit mode

Press: Wq Save exit file

Use the following statement to make the environment variable effective

[Email Protected]:source ~/.BASHRC

There is a space between source and ~ symbol, ~ indicates your home directory, is the alias of the home directory

Use

[email protected]:swift-version

command to see if the SWIFT environment is configured.

The output will be as follows

3.0 (swift-3.0.  1-preview-1)                                                                                                                    target:x86_64

So far, the environment is fully configured.

4. Use the REPL command-line interactive environment to learn basic syntax

(see http://wiki.jikexueyuan.com/project/swift/for Swift syntax and API learning)

Command line strikes Swift to enter the interactive environment

3.0 (swift-3.0.  1-preview-1 for assistance.                                                                                               1

Input, enter the result after the return:

3.0 (swift-3.0.  1-preview-1 for assistance.                                                                                               1 1+12  2

Press the CTRL and D keys to exit the REPL interactive environment
