Is Swift slower than C++?

Swift is a powerful and intuitive programming language for iOS, iPadOS, macOS, tvOS, and watchOS . Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.

These operations that Swift performs to manage things costs time and resources; granted, not much but it still takes some effort. This is why Swift is slower than C/C++ . JavaScript V8 vs C++ g++ (64-bit Ubuntu one core) I’m not switching to JavaScript anytime soon.

Swift is the powerful programming language that powers Apple’s app platforms, and it’s also the language we use for SwiftUI.
