Swift 5 Packaged by IOanyT Innovations - Amazon Linux 2

OVERVIEW

Swift is friendly to new programmers. It’s an industrial-quality programming language that’s as expressive and enjoyable as a scripting language. Writing Swift code in a playground lets you experiment with code and see the results immediately, without the overhead of building and running an app.

Swift defines away large classes of common programming errors by adopting modern programming patterns:

• Variables are always initialized before use.

• Array indices are checked for out-of-bounds errors.

• Integers are checked for overflow.

• Optional ensure that nil values are handled explicitly.

• Memory is managed automatically.

• Error handling allows controlled recovery from unexpected failures.

GET STARTED

To verify the installation, follow the below instructions

Step 1. Connect to SSH:

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

2. In the navigation pane, choose Instances.

3. Select the instance and choose Connect.

4. Choose SSH Client

5. Copy the SSH command and paste it into the terminal.

ssh ec2-user@publicIP -i [Path of key pair file]

If it shows an access denied message run the following command, then run the above command again to connect via ssh.

chmod 400 [Path of key pair file]

Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user

Step 2. Verify the installation

Follow the steps to verify the swift installation

1. Login with ssh

2. Type the below command to check the version

swift --version

You will see the responses as shown below.

How to use swift language in the terminal:

1. After connecting with ssh write the below command:

swift

2. After that enter the code given below :

print("Hello World!")

4. If you get the Hello world! in output then your swift is working properly.

To monitor and assess application functions:-

a. Navigate to your Amazon EC2 console and verify that you're in the correct region.

b. Choose Instances and select your launched instance.

c. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
