Lower deployment targets to iOS 13 / macOS 10.15#216
Merged
Conversation
The iOS 18 / macOS 15 floors set during the v2.0.0 toolchain modernization were not driven by any actual API requirement — the library uses only CoreText, CoreGraphics, and UIKit/AppKit fundamentals available since iOS 8 and macOS 10.8, with no @available gates anywhere in the source. Drop the floors to iOS 13 / macOS 10.15 so the library is usable on the broader install base (incl. devices like iPad Air 2 stuck on iOS 15). Updates Package.swift, all three xcodeprojs (iosMath, MacOSMath, SwiftMathExample), and the README. Fixes #214 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Code Review
This pull request lowers the deployment targets for the project, changing the minimum iOS version from 18.0 to 13.0 and the minimum macOS version from 15.0 to 10.15 across the project configuration files, package manifest, and documentation. There are no review comments, and I have no additional feedback to provide.

Summary
@availablegates anywhere in the source.Package.swift, all three xcodeprojs (iosMath,MacOSMath,SwiftMathExample), and the README. CHANGELOG left untouched — the v2.0.0 entry remains historically accurate; a new entry can be added when cutting the next release.Fixes #214.
