Xcode 6Swift
Why you should use Swift?
• Safety
• type checks
• optionals
• typed collections
• better memory management
• Bunch of functional paradigms
• immutability by default
• generics
• closures
• tuples
• etc.
Why you should use Swift?
• Playgrounds and REPL
• Good integration with Obj-C code
• Good, short and readable syntax
* - http://fuckingblocksyntax.com
Obj-C block declaration*returnType (^blockName)(parameterTypes) = ^returnType(parameters) {...};
Swift closurevar block = { (var parameters) in
…}
Why you should’n?
• Syntax will be changed in future
• Performance is not so good, as shown in Keynote
• It’s impossible to create a Framework
• Lacks some usual object-oriented language features (Access modifiers, etc.)
Xcode 6
• View Debugging
• Swift support
• Universal storyboards
• Interface builder supports custom objects
• etc.
Demo
Thank You!
