Swift

Protocol-oriented, multi-paradigm. First appeared 2014; systems and ownership; apple platforms, server-side.

This record is a summary. The atlas carries a full article on Swift covering its semantics, memory model, standard history and ecosystem, plus a Swift reference. Read the Swift article.

Record¶

Dates are first public release or publication, not the start of internal development. Colour on the typing and memory tags encodes kind, never rank.

Influence¶

Figure 1. Swift in the influence graph: recorded ancestors on the left, languages that record it as an influence on the right. Every node links to its own record. Edges name indexed languages only, so an empty side means no indexed relative, not none at all. Source: languages.json.

Within the Systems and ownership¶

Predictable performance without a tracing collector, achieved through ownership, borrowing, or reference counting checked at compile time.

Language	First appeared	Typing	Memory	Execution
Ada	1980	Static, strong	Manual, pooled	AOT compiled
Rust	2010	Static, strong, inferred	Ownership and borrowing	AOT compiled (LLVM)
Zig	2016	Static, strong	Manual, explicit allocators	AOT compiled (LLVM)
Hare	2022	Static, strong	Manual, no runtime collector	AOT compiled (QBE)
Mojo	2023	Static, strong; dynamic Python interop	Ownership and borrowing	AOT compiled (MLIR/LLVM)
