Usage

1. swiftc main.swift -emit-module-path main.swiftmodule -emit-executable -enable-private-imports -Xfrontend -enable-implicit-dynamic
2. ./main -> prints From original bar()
3. swiftc -emit-library inject.swift -o inject.dylib -I . -Xlinker -undefined -Xlinker suppress -Xlinker -flat_namespace -Xfrontend -disable-access-control
4. DYLD_INSERT_LIBRARIES=inject.dylib ./main -> prints From replacement bar()

Notes

• Passing -Xfrontend -enable-implicit-dynamic removes you from having to add dynamic to everything you want to be replacable

    /// So, lets talk about AppKit. The way this function works is by passing a delegate (which is required
    /// to be a NSObject, but here is typed as Any) which turns out to be the same type as `self`, a Selector,
    /// which in this case is `_something:didSomething:soContinue:` (not kidding), and some "contextInfo"
    /// (which is actually a block). While all of these arguments appear to be optional, passing nil through
    /// to the function call that `shouldCloseSelector` defines, or passing nil to super, will cause the app
    /// to crash. So then we need to call the function on `delegate` defined by `shouldCloseSelector`.
    ///
    /// According to the documentation the function signature for this selector looks like this:
    /// - (void)document:(NSDocument *)doc shouldClose:(BOOL)shouldClose contextInfo:(void *)contextInfo
    ///
