  • SR-7531 SwiftPM doesn't set CLANG_ENABLE_MODULES

Issue Description:

I integrated the stephencelis/SQLite.swift package into my project and re-generated the Xcode project using the subcommand `generate-xcodeproj`. The project builded successfully using the CLI (`swift build`) but not in Xcode. The ObjC target is using the Swift compiler by default but it should use ObjC. We already did some investigation and we found a workaround: stephencelis/SQLite.swift#828

Package.swift file: https://github.com/stephencelis/SQLite.swift/blob/f8032b2c2cda38311bda44eef2c5570022fe2f33/Package.swift#L4

Enable modules is disabled for C targets because of complicated reasons which break the indexing/autocompletion. This is because SwiftPM target model doesn't map 1:1 with Xcode's framework model. In Swift 4.2, we improved this situation for C targets that contain an umbrella header without any non-modular imports (import stuff outside of the target). Your package is compatible with this and the generated project starts working as expected if you rename `SQLite-Bridging.h` to `SQLiteObjc.h`.
