LinkKit 7.0.0 - 2026-06-09

LinkKit 7.0.0 is a major release introducing a modernized, session-based architecture and native SwiftUI support. This version significantly reduces the SDK footprint while offering more granular control over Link flows.

⚠️ Breaking Changes & Deprecations

• Session-based API: The legacy Handler API has been replaced by specialized Session objects (e.g., PlaidLinkSession, PlaidLayerSession).
• CocoaPods Retirement: CocoaPods is no longer a supported distribution method. Please migrate to Swift Package Manager (SPM) to continue receiving updates.
• Swift-Only Core: The core LinkKit module is now Swift-only. For Objective-C support, you must explicitly import the new LinkKitObjC module.

Requirements

Name	Version
Xcode	>= 16.1.0
iOS	>= 15.0
Swift	>= 5.10

Key Enhancements

• SDK Footprint Reduction: Reduced the executable size from ~6.4MB to 2.5MB, optimizing app bundle sizes.
• Native SwiftUI Support: Introduces native modifiers like .plaidLink(isPresented:token:...) and the .sheet() method on session objects, removing the need for UIViewControllerRepresentable.
• Pre-Initialization & onLoad: The onLoad callback is now a first-class citizen in LinkTokenConfiguration. You can now initialize sessions in the background and only present UI when the SDK is "Ready."
• Modernized FinanceKit Sync: Moved FinanceKit functionality to PlaidFinanceKit with support for async/await and a new SyncBehavior enum.

Feature Updates

Standard Link

• Unified LinkTokenConfiguration where onSuccess, onExit, onEvent, and onLoad are all defined at initialization.
• Replaced Plaid.create result-switching with a throwing Plaid.createPlaidLinkSession method.

Plaid Layer

• Introduced LayerTokenConfiguration and PlaidLayerSession.
• Added session.submit(data:) to programmatically pass user information (Phone, DOB) to an active Layer session.

Headless Link

• Optimized PlaidHeadlessSession which removes the need for noLoadingState flags; the session is entirely invisible until programmatically started.

Embedded Link

• New EmbeddedSearchView (SwiftUI) and EmbeddedSearchUIView (UIKit) provide a "search-first" native experience without manual view wrapping.
