MergeableView is a Swift package for building iOS and macOS interfaces where items can be visually merged together when a user drags one toward another. The Liquid Glass effect refers to a translucent, fluid looking visual style that makes the items appear to flow and merge organically on screen. The problem it solves is that implementing drag to merge gestures with animated glass style visuals from scratch in SwiftUI is complex. MergeableView provides a small set of ready made building blocks so a developer does not have to build this interaction from first principles. To use it, you wrap your views in a MergeableContainer, which sets up the shared glass effect and a coordinate space for tracking merges. Each item you want to be mergeable gets tagged with a mergeableItem modifier. When a user drags one item onto another and releases, an onMerge callback fires with the source and destination indices, letting you update your own data however you choose, for example combining two text tokens into one. You would reach for this library when building an iOS or macOS app where users rearrange or combine objects with a tactile, animated feel, think tag managers, playlist builders, or any interface where merging items is a core interaction. It requires iOS 26 or macOS 26 and Swift 6, is installed through Swift Package Manager, and comes with a runnable example app included in the repository. It is released under the MIT license.
