The project I am working includes both safari and iMessage extensions. Now I am trying to add watch extension too. Without watch extension it compiles without an error(compiling with new build system not legacy). However after adding the watch target I started getting build input file cannot be found error for watch extension appex.I tried changing build system, changing valid architectures but none of them worked.I do have another project with exact same project settings and it works fine.I am using Xcode 10.3(also getting same error with Xcode 11) Project deployment target is iOS 9.0 Watch app deployment target is watchOS 5.0Any help will be appreciated.
