Enterprise iOS app development in Swift

Safety and Readability

Swift's syntax is clear and concise, intuitive to those familiar with JavaScript, Python and C++. Optional types and value binding make null pointer references impossible.

Performance

Swift is type-safe, catching errors at compile time. Type inference means you don't have to manually assign types to every piece of data.

Interoperability with Objective-C

Use Swift and Objective-C in the same project for easy adoption in existing code. Generics, closures and type inference make the code faster.

Memory Management

Swift uses Automatic Reference Counting (ARC) for efficient memory management across procedural and object-oriented code, enhancing app performance.

Open Source

Swift is open source — its code is public and developers can contribute. 'Playgrounds' let you test a chunk of code without creating a whole new program.

Protocol-Oriented Programming

Developed by Apple for iOS, macOS, watchOS and tvOS. Encourages protocol-oriented programming for more extensible, flexible and reusable code.

Objective-C

• Semicolons required
• Types must be declared
• Header files
• Pointers
• KVO and custom setters

Swift

• Types are inferred
• Functions are first class objects
• Collections are typed using generics
• Simpler string manipulation
• Memory is managed automatically
