Embedded Swift: Exploring the Future of Swift in Embedded Systems

The article discusses the concept of Embedded Swift and its potential implications for developers working with embedded systems. Embedded Swift is a version of Swift that is specifically designed for use in resource-constrained environments, such as microcontrollers and IoT devices. The article highlights the need for removing certain features, like the print() function, in order to optimize memory usage and improve performance. It also mentions the possibility of providing alternative implementations to maintain source code compatibility. The author compares this approach to Rust's distinction between std and core, allowing developers to replace pieces of std and access more abstractions. The article confirms the existence of a prototype for Embedded Swift and mentions plans to add its functionality into the compiler under experimental flags. Overall, Embedded Swift presents an exciting opportunity for developers to leverage the power and expressiveness of Swift in the world of embedded systems.
