The Swift.org website has been undergoing a redesign to make it more welcome to newcomers and emphasize key features like Swift's multiplatform support.
Despite positive reactions to the redesign, some users mentioned issues like an analytics script causing problems and concerns about language superiority claims.
One user expressed concern about the wording used on the homepage and questioned the need for overhyped statements that might disparage other programming languages.
Feedback on Swift's performance included both praise and criticism; for example, one user found Swift's string parsing to be slow but Swift can perform well in certain scenarios.
Swift developers should be cautious with certain operations, as there can be unexpected sources of slowness, especially with string handling and bridging.
Recent optimizations for Swift strings were announced at WWDC to address performance concerns.
A specific case highlighted bridging non-ASCII NSMutableStrings from Objective-C may have tradeoffs in performance, especially when double-bridging strings back to Objective-C.
Previous topics discussed included Swift 5 Exclusivity Enforcement and Swift 1.0 Performance and Compilation Times.
