Allow (most) keywords as argument labels
• Accepted Proposal - SE-0001
Allow the use of all keywords except inout, var, and let as argument
labels.

Tips and Tricks for Swift & Dot Swift 2016
- 1. Tips and Tricks for Swift Dot Swift 2016 Adam Gask March 2016
- 2. Overview • Dependancy Management - left-pad (Gate?) • Closures & Error Handling - Live Coding Demo • Swift 2.2 - All the deprecation warnings • Swift 3 & Roadmap - All the breaking changes • Swift Stack • Pizza! -🍕+ 🍻 • Dot Swift Recap
- 3. Dependancy Management • left-pad (Gate?)
- 5. Dependancy Management • TLDR: • Azer Koçulu • Naming issue with Azer's ‘Kik’ npm package • Legal issues were raised • ‘Kik’ module was transfered to Kik • left-pad was removed (along with 272 others) And that's how JavaScript app development works in 2016. ®
- 7. Dependancy Management • Cocoapods • Carthage
- 9. Dependancy Management • Cocoapods • Carthage • Checking all dependancies into source control • Just write all your own code… right? 😉
- 10. Closures & Error Handling “Closures are self-contained blocks of functionality that can be passed around and used in your code. Closures in Swift are similar to blocks in C and Objective-C and to lambdas in other programming languages.” The Swift Programming Language (Swift 2.1)
- 11. Closures & Error Handling - Live Coding Demo
- 12. Closures & Error Handling Really useful links: • How Do I Declare a Closure in Swift? (NSFW URL, but content is fine) • Swift closures cheatsheet • Swift Closures — Everyday Gems • Part 1 • Part 2
- 13. Swift 2.2 • Raft of non-breaking changes • A gentle preparation for 3.0 • Linter warnings to help you on your way • 2.2 is the time to fix your code, not 3.0 • Still bugs to fix - JIRA (Look for the label “StarterBug”)
- 14. Swift 2.2 Referencing the Objective-C selector of a method • Accepted Proposal - SE-0022 class vc: UIViewController { let button = UIButton(type: .System) func addTarget() { button.addTarget(self, action: #selector(vc.buttonTapped(_:)), forControlEvents: .TouchUpInside) }}
- 15. Swift 2.2 Naming Functions with Argument Labels • Accepted Proposal - SE-0021 extension MyModel { func insertData(data: NSData, at index: Int) {} func insertData(data: NSData, aboveData siblingData: NSData) {} func insertData(data: NSData, belowData siblingData: NSData) {} }
- 16. Swift 2.2 Modernizing Swift's Debugging Identifiers • Accepted Proposal - SE-0028 __FILE__ => #file __LINE__ => #line __COLUMN__ => #column __FUNCTION__ => #function (Added during review) __DSO_HANDLE__ => #dsohandle
- 17. Swift 2.2 Allow (most) keywords as argument labels • Accepted Proposal - SE-0001 Allow the use of all keywords except inout, var, and let as argument labels. for i in 1.stride(through: 9, by: 2) { print(i) } func find(data: NSData, in array: [NSData]) { }
- 18. Swift 2.2 Tuple comparison operators • Accepted Proposal - SE-0015 let singer = ("Taylor", "Swift") let alien = ("Justin", “Bieber”) if singer == alien { print("Matching tuples!") } else { print("Non-matching tuples!") }
- 19. Swift 2.2 Arrays and other slice types now have removeFirst() This complements the existing removeLast() var array = Array(1...10) array.removeFirst() for number in array { print("(number) green bottles") }
- 20. Swift 2.2 • Remove the ++ and -- operators - SE-0004 • Removing var from Function Parameters - SE-0003 • Remove C-style for-loops with conditions and incrementers Say goodbye to… for(var a = 0; a <10 ; a++)
- 21. Swift 3.0 & Roadmap What we know is coming: • Stable ABI - “guarantee a level of binary compatibility moving forward” • Complete generics - an array of Equatable elements is Equatable • Focus and refine the language
- 22. Swift 3.0 & Roadmap Better Translation of Objective-C APIs Into Swift • Accepted Proposal - SE-0005 let content = listItemView.text.stringByTrimming… CharactersInSet(NSCharacterSet.whitespaceAnd NewlineCharacterSet()) let content = listItemView.text.trimming(.whitespace… AndNewlines)
- 23. Swift 3.0 & Roadmap Apply API Guidelines to the Standard Library • Accepted Proposal - SE-0006 -public protocol SequenceType { ... } => +public protocol Sequence { ... } sort() => sorted(), sortInPlace() => sort() reverse() => reversed() enumerate() => enumerated()
- 24. Swift 3.0 & Roadmap What we know is out of scope: • Full source compatibility - there will be breaking changes • Concurrency • C++ Interoperability • Major new library functionality
- 25. Did you know? Possible full stack in Swift?
- 26. Swift Stack Server Options • Swift Server IO • Perfect • Kitura
- 29. Could be worse…
- 30. Dot Swift 2016 Paris - 29th January 2016
- 31. Dot Swift 2016 TLDR: • Annual European Swift conference • Packed schedule of 12 talks • Ranging from UI, Live Coding & “The Bigger Picture” • Two sessions of 4 lightning speakers • Each talk had a structured Q&A after
- 32. The Talks • Creating an animation with CAReplicatorLayer • Showing that animations can be short and succinct • Talk • Alessandro Ludovici
- 33. The Talks • The Empathetic Developer • Probably most thought provoking talk • Talk • Michael May
- 34. The Talks • Tiny Networking in Swift • Easily the best Live Coding Demo • Talk • Chris Eidhof
- 35. The Talks • Other notable talks: • Swift [and the] Evolution - TJ Usiyan • CloudKit: The Forgotten Cloud - Paul Ardeleanu • iOS UIs built as Lego bricks - Victor Wang • Beyond JSON in Swift - Maxim Zaks • Going Swift and Beyond - Ayaka Nonaka
- 36. Featured Talk • Localization is hard • Lots of takeaways popular & obscure • Talk • Roy Marmelstein
- 37. And Finally • Protocol Oriented Programming • Best use of cartoon characters • Talk • Grégoire Lhotellier
- 38. Thank you for your time Adam Gask @_AJ9
