Bug: An Xcode 11 project which is generated from an executable-type Swift Package which has RealmSwift as a dependency does not build.

Goals

The goal is to have an Xcode 11 project which is generated from an executable-type Swift Package which has RealmSwift as a dependency that can successfully build and run.

Expected Results

What Swift Package that builds from the command line is also expected to build in an Xcode 11 project generated from the same package.

Actual Results

Build fails as show below in the steps to reproduced.

Steps to Reproduce

1. Setup an executable type Swift Package with RealmSwift as a dependency.
   • Example Package.swift
   • GitHub repository `marc-medley/RealmSPMXcode` is an example Swift Package with RealmSwift as a dependency.
2. Verify build from the command line on has only a few warnings.

swift build

# RealmSPMXcode/.build/checkouts/realm-cocoa/Realm/RLMRealm.mm:135:17: 
# warning: method definition for 'privilegesForRealm' not found [-Wincomplete-implementation]
# @implementation RLMRealm {

# RealmSPMXcode/.build/checkouts/realm-cocoa/include/Realm/RLMRealm.h:658:1: 
# note: method 'privilegesForRealm' declared here
# - (struct RLMRealmPrivileges)privilegesForRealm;

## ... snip ...

# warnings generated.
# [139/139] Linking RealmSPMXcode

1. Generate an Xcode 11 project from the Swift Package.

swift package generate-xcodeproj 
# generated: ./RealmSPMXcode.xcodeproj
open RealmSPMXcode.xcodeproj/

1. Build in Xcode with "My Mac" as the target.

_Workaround: Edit RealmCore 5.23.5/realm/util/terminate.cpp to remove the

REALM_VER_CHUNK

expansion related error:_

REALM_NORETURN void terminate(const char* message, const char* file, long line) noexcept
{
    std::stringstream ss;
    // ss << file << ":" << line << ": " REALM_VER_CHUNK " " << message << '\n'; // :BEFORE:
    ss << file << ":" << line << ": [realm-core-5.23.5] " << message << '\n';    // :AFTER:
    terminate_internal(ss);
}

After the about workaround more errors occur:

Notice that .build/checkouts/realm-cocoa/Realm/ObjectStore/src/impl/results_notifier.hpp
and .build/checkouts/realm-cocoa/Realm/ObjectStore/src/impl/results_notifier.cpp are in the same directly.

Next attempted workaround ...

// #include "impl/results_notifier.hpp"
#include "results_notifier.hpp"

... leads to yet more errors:

Code Sample

• Example Package.swift
• GitHub repository `marc-medley/RealmSPMXcode` is an example Swift Package with RealmSwift as a dependency.
