Swift 5.3 Released

Holly Borla:

Swift 5.3 significantly improves both binary code size and runtime memory usage. Measurements of these improvements have yielded exciting results across various projects[…]


The automatic indentation implementation in SourceKit was overhauled in this release, fixing ~50 feedback reports in the process.


Repeated code completion invocations inside function bodies are now up to 15 times faster compared to Swift 5.2.


Swift 5.3 builds upon the diagnostics improvements in Swift 5.2 to further enhance the quality and precision of error messages, especially in SwiftUI code. More specifically, the transition to the New Diagnostics Architecture is now complete in Swift 5.3!
