Yes, iOS developers should consider moving their apps to Swift. Swift is designed to be an expressive and safer programming language that simplifies the process of writing software. It is fast, modern, safe, and a joy to write, making it an ideal language for app development. Swift is used by almost 1 million apps and is becoming a compelling choice for even the most performance-sensitive and secure code.
Apple is committed to adopting Swift in their C code bases, and moving to Swift will improve the quality of software both at Apple and throughout the industry. Swift's safety, speed, and approachability, combined with built-in C and C++ interoperability, make it the best choice to succeed C. Additionally, SwiftUI, which leverages Swift's unique features, allows developers to build UI apps better and faster, and share more code across more devices.
