Completely pointless non-actionable advice.

"Help! My compact got stuck in the snow"

"Buy a 4x4 and replace the wheels with tracks, that will get you going anywhere"

The UI in client code, especially for something like a note taking app, is often the entirety of the work such that your advice actually introduces more work like having to maintain C++ knowhow. Let me guess, you already work with C++ daily.

Already written on Swift :(
