Swift

• Motivation
• Objective-C is too low-level
• Features
• Static Typing with type-inference
• Generics (e.g. typed containers)
• String Templating (like handlebars)
• Closures
• Functions as first class citizens
• Operator overloading
• LLVM
• Low Level Virtual Machine
• LLVM Bytecode same as CLI in .NET
• Swift -> LLVM bytecode -> machine code
• Optimized for mobile
• Integration with Objective-C
• Bridging Header: Creates wrapper code for a set of Objective-C headers
