From 786da0807f7826f07e5083173e0a5f77df5511a5 Mon Sep 17 00:00:00 2001 From: tiagocandido Date: Mon, 28 Jul 2025 21:52:02 +0200 Subject: [PATCH 1/5] Add embedded checkout data models (Schema 2025-04) This commit introduces the complete data model infrastructure for embedded checkout functionality using the Schema 2025-04 specification. Key additions: - CheckoutStatePayload, CheckoutCompletePayload, WebPixelsPayload for event handling - Complete embedded checkout data types with 'Embedded' prefixes to avoid naming conflicts - CheckoutOptions and AppAuthentication for configuration - AnyCodable helper for handling arbitrary JSON payloads - Error payload models for embedded checkout error handling All types are prefixed with 'Embedded' to avoid conflicts with existing types in the codebase. This maintains backward compatibility while enabling new embedded checkout functionality. --- .swiftformat | 4 +- .../EmbeddedCheckoutModels.swift | 273 ++++++++++++++++++ 2 files changed, 275 insertions(+), 2 deletions(-) create mode 100644 Sources/ShopifyCheckoutSheetKit/EmbeddedCheckoutModels.swift diff --git a/.swiftformat b/.swiftformat index 2c7479e32..4c4c57c16 100644 --- a/.swiftformat +++ b/.swiftformat @@ -6,6 +6,6 @@ --allman false --semicolons inline --trimwhitespace always ---disable redundantReturn,hoistAwait,preferKeyPath,redundantInternal,redundantPublic ---swiftversion 5.7.1 +--disable redundantReturn,hoistAwait,preferKeyPath,redundantInternal,conditionalAssignment +--swiftversion 5.9 --extensionacl on-declarations diff --git a/Sources/ShopifyCheckoutSheetKit/EmbeddedCheckoutModels.swift b/Sources/ShopifyCheckoutSheetKit/EmbeddedCheckoutModels.swift new file mode 100644 index 000000000..371b425b0 --- /dev/null +++ b/Sources/ShopifyCheckoutSheetKit/EmbeddedCheckoutModels.swift @@ -0,0 +1,273 @@ +/* + MIT License + + Copyright 2023 - Present, Shopify Inc. + + Permission is hereby granted, free of charge, to any person obtaining a copy + of this software and associated documentation files (the "Software"), to deal + in the Software without restriction, including without limitation the rights + to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + copies of the Software, and to permit persons to whom the Software is + furnished to do so, subject to the following conditions: + + The above copyright notice and this permission notice shall be included in all + copies or substantial portions of the Software. + + THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
