Server-Side Swift in Action!

1 j'aime•304 vues
Practical talk on how to write your first server on Swift This talk was given in December 2016, when server-side has been around for just few months. The idea was showing my fellows from SwiftBA meetup what I had researched on the topic during the last month, and give them a practical example (live coding) on how to implement your server. https://www.meetup.com/SwiftBA/events/234648546/ https://www.youtube.com/watch?v=Wtcfnq8WMdI

- 4. www.erlang-solutions.com Where do we start? ● First, you need a framework in order to have server-side support… ○ (Unless you're so hardcore to DIY) ● There are several: ○ Kitura (IBM) ○ Perfect ○ Vapor ○ Zewo ○ And more... Case study

- 13. www.erlang-solutions.com Let's DO IT! ● Let's create our first server! ○ http://kitura.io/ ○ https://github.com/IBM-Swift/Kitura/ ● Reminder for Pablo: ○ Do live coding until we get the server running!
- 14. www.erlang-solutions.com First thing you notice... ● WHERE IS MY XCODE??
- 15. www.erlang-solutions.com Second thing you notice ● I knew you'll miss me one day... (BTW: http://www.textfromxcode.com/ for fun!)
- 17. www.erlang-solutions.com Everything's Not Lost ● If you miss Xcode, you can still: ○ Open your .swift files with Xcode ● No, really, you can: ○ swift package generate-xcodeproj

- 19. www.erlang-solutions.com But be aware! ● Here are some gotchas:
- 21. www.erlang-solutions.com Another gotcha ● Console apps do NOT bundle stuff ● Console apps do NOT use NSBundle ● Do not use files from your bundle to store your configurations… ○ (e.g. a plist)
- 22. www.erlang-solutions.com And so on... ● You will encounter several of these blockers along the way… ○ Stack Overflow is your friend! :) ○ Google is your BEST friend! :D
- 23. www.erlang-solutions.com What now? ● Can't we turn this into something more interesting?
- 25. www.erlang-solutions.com Meet Jolly ● https://github.com/inaka/Jolly ○ Server written in Swift ■ Using Kitura framework ● Therefore Swift Package Manager ■ Unit-tested ■ Running on Linux (well, not really…)
- 26. www.erlang-solutions.com Swift on Linux ● You can run Swift code on Linux: ○ https://ashfurrow.com/blog/swift-on-linux/ ● BUT: ○ macOS environments use Foundation ○ Linux environments use SwiftFoundation
- 27. www.erlang-solutions.com Foundation Swift-Foundation http://blog.krzyzanowskim.com/2016/03/23/status-of-portable- swift-code/ ● Written in Objective-C ● Swift-compatible ● We use it everyday ● Written in Swift ● Not obj-c compatible ● Brand new! ● Still not finished! import Foundation import Swift
- 28. www.erlang-solutions.com The Last Slide ● Server-side Swift is a reality ● However, it's still on its early stages ● So is Swift Package Manager ● Swift on Linux is too green yet (to me) ● Swift is getting everywhere
