Description
Weak-link
SwiftUICore.frameworkin both SPM (Package.swift) and CocoaPods (IONCameraLib.podspec) to fix a crash on launch affecting iOS 15 and 16 devices.Context
Since iOS 17, Apple split SwiftUI into two frameworks:
SwiftUI.frameworkandSwiftUICore.framework. When this library is compiled with the iOS 17+ SDK, the linker creates a hard runtime dependency onSwiftUICore— even though all SwiftUI APIs used are compatible with iOS 14+. On iOS 15/16 devices,SwiftUICoredoesn't exist, sodyldfails to load the app and it crashes immediately on launch.Weak-linking makes
SwiftUICorean optional load-time dependency. On iOS 15/16,dyldignores its absence and the app starts normally; on iOS 17+, the framework is present and loaded as usual — no behavioural change.Fixes: ionic-team/capacitor-camera#44
