This is not a solution. it failed at the build time with error: "The package product 'MyPackage' cannot be used as a dependency of this target because it uses unsafe build flags."

Unfortunately, it's "NO". Currently, building and distributing the XCFramework is the only way to make your package as mergeable. When you try to configure the linkerSettings to enable MAKE_MERGEABLE, it will failed building w/ error saying "The package product cannot be used as a dependency of this target because it uses unsafe build flags." even though the product was defined as .dynamic If someone has any good solution, please let me know!
