Platform Policy for LightweightChartsIOS

Effective Version: 5.1.0

This document defines the supported platform and distribution policy for the LightweightChartsIOS wrapper library.

Supported Distribution Path

Swift Package Manager only

As of version 5.1.0, Swift Package Manager is the only supported distribution path for this repository.

Distribution Path Status
Swift Package Manager Supported
CocoaPods Removed

Minimum Platform Version

iOS 15.0

As of version 5.1.0, the minimum supported iOS version is 15.0.

Why iOS 15.0?

  1. Swift 6 and the async/await-first API are the baseline for the current release.
  2. The wrapper depends on modern WebKit and concurrency behavior that is aligned with iOS 15+.
  3. Supporting older versions would increase maintenance burden for a release that already contains intentional breaking changes.

Migration Impact for Users

Apps targeting iOS earlier than 15.0 or relying on CocoaPods must remain on an older release line or migrate to:

  • iOS 15.0+
  • Swift 6
  • Swift Package Manager

Maintenance Rule

Platform minimum version increases and supported distribution path changes are major-release decisions and must be reflected consistently in:

  1. Package.swift
  2. README.md
  3. CHANGELOG.md
