Hello. I'm building an iOS application that builds a framework named Design.framework using Xcode 16.1. When I launch my application on iOS 17.X, i get the following runtime error dyld[47899]: Library not loaded: /System/Library/Frameworks/SwiftUICore.framework/SwiftUICore Referenced from: <E625A246-E36B-351A-B077-CC38BAB5E07B> /Users/v/Library/Developer/Xcode/DerivedData/iScribd-bexojbdreldwkvbpzioqueldnvng/Build/Products/Debug_AppStore-iphonesimulator/Design.framework/Design Reason: tried: '/Users/v/Library/Developer/Xcode/DerivedData/iScribd-bexojbdreldwkvbpzioqueldnvng/Build/Products/Debug_AppStore-watchsimulator/SwiftUICore.framework/SwiftUICore' (no such file), '/Users/v/Library/Developer/Xcode/DerivedData/iScribd-bexojbdreldwkvbpzioqueldnvng/Build/Products/Debug_AppStore-iphonesimulator/SwiftUICore.framework/SwiftUICore' (no such file), '/Users/v/Library/Developer/Xcode/DerivedData/iScribd-bexojbdreldwkvbpzioqueldnvng/Build/Products/Debug_AppStore-watchsimulator/PackageFrameworks/SwiftUICore.framework/SwiftUICore' (no such file), '/Users/v/Library/Developer/Xcode/DerivedData/iScribd-bexojbdreldwkvbpzioqueldnvng/Build/Products/Debug_AppStore-iphonesimulator/PackageFrameworks/SwiftUICore.framework/SwiftUICore' (no such file), '/Library/Developer/CoreSimulator/Volumes/iOS_21C62/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.2.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/SwiftUICore.framework/SwiftUICore' (no such file), '/System/Library/Frameworks/SwiftUICore.framework/SwiftUICore' (no such file, not in dyld cache), '/Library/Developer/CoreSimulator/Volumes/iOS_21C62/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.2.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/SwiftUICore.framework/SwiftUICore' (no such file) This error does not happen on iOS 18+.

And how am I supposed to handle devices prior to iOS 18 which do not have this library? is adding the linker flag the right way forward?
