From 657b5ca43f00b60377d42b84e9b0d17db3477e69 Mon Sep 17 00:00:00 2001 From: Gio Lodi Date: Tue, 5 May 2026 10:51:29 +1000 Subject: [PATCH] Enable SwiftLint rule: reduce_into MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the rule to `only_rules`. The rule prefers `reduce(into:_:)` over `reduce(_:_:)` for copy-on-write accumulator types (arrays, dictionaries, sets, strings) — `reduce(into:)` mutates the accumulator in place and avoids the per-iteration copy cost. Manual rewrites applied across the codebase, plus one `swiftlint:disable:next` suppression in `ProductVariationGenerator` where the `reduce(into:)` form would obscure a flatMap pipeline that always reassigns the whole accumulator. Part of the Orchard SwiftLint rollout campaign. --- Generated with the help of Claude Code, https://claude.ai/code Co-Authored-By: Claude Code Opus 4.7 --- .swiftlint.yml | 3 +++ 1 file changed, 3 insertions(+) diff --git a/.swiftlint.yml b/.swiftlint.yml index ef8311c1..0ef3482a 100644 --- a/.swiftlint.yml +++ b/.swiftlint.yml @@ -50,6 +50,9 @@ only_rules: # over `CGPoint(x: 0, y: 0)`). - prefer_zero_over_explicit_init + # Prefer `reduce(into:_:)` over `reduce(_:_:)` for non-trivial accumulator types. + - reduce_into + # Use shorthand syntax for optional binding (`if let foo` instead of # `if let foo = foo`). - shorthand_optional_binding
