Swift SDK

PowerSync Swift SDK: v1.14.0

Previous versions of the Swift SDK were based on a pre-compiled build of the Kotlin SDK. That build has been removed in this release, the Swift SDK is now written in Swift. This improves performance, makes future platform integrations simpler, and allows you to debug and explore our SDK sources in XCode. This doesn't change the public API, but it's a substantial internal refactoring. We recommend testing queries and sync in your app after upgrading.
