I've been using Swift Packages for both iOS/macOS clients and Vapor backend development for some time. I'm in the process of gathering the lessons learned into a generic set of Open Source repositories: VaporExampleLabs/Synergy*.
It is possible to have Swift Packages which can be used on the Swift server side, and on iOS devices and in macOS applications. A greater separation between the views (Vapor View, iOS UIView, macOS NSView) and underlaying application logic, allows more code to be shared in Swift Packages across the platforms.
The VaporExampleLabs/Synergy* collection of packages & projects provides various working pieces of how to setup a Vapor server, iOS device client and a macOS client to use the same Swift Packages.
Each part highlights some key findings for the use of a Swift code shared in both Server backend and Client device software development.
Note: The Synergy set of projects and packages are still a work in progress for gathering lessons learned. The goal is to create a full (self-contained) set of backend-to-client connected examples sharing common Swift Packages.
SynergySqliteC ▴
Sometimes lower level libraries are not common between the server and device. For example, the database Object Relationship Model (ORM) is different for Vapor and iOS/macOS have CoreData. Vapor provides Fluent. iOS/macOS provides CoreData.
This example illustrates direct use the SQLite C source code at the lowest level.
SynergySqliteC ⇗ shows how to setup a cross platform C library into a Swift Package.
SynergySQLiteFramework ▴
SynergySQLiteFramework ⇗ provides a generic Swift framework for using the C-base Swift Package SynergySqliteC.
SynergyAPI ▴
SynergyAPI ⇗ provides the Codable interface for the collection of Synergy applications. Uses the generics SQLite package SynergySQLiteFramework.
SynergyVapor ▴
SynergyVapor ⇗ provides an example Vapor web application which uses the SynergyAPI.
Synergy Clients ▴
Synergy ⇗ provides both an iOS and macOS client Xcode projects. Both the iOS and macOS clients use the SynergyAPI package.
Swift Packages in iOS/macOS Applications
Note that at this time the Package Manager has no support for iOS, watchOS, or tvOS platforms. Source: Swift Package Manager Project
Even though the Swift Package manager can not directly create an iOS or macOS application, Swift Packages can still be used as subprojects in the respective Xcode application projects.
cd SynergyAPI
swift package generate-xcodeproj \
--xcconfig-overrides Package.iOS.xcconfig \
--output SynergyAPI_iOS
swift package generate-xcodeproj \
--xcconfig-overrides Package.macOS.xcconfig \
--output SynergyAPI_macOS
