Reading this brings back so many memories of the early 2000s, using Cheat Engine to inject code into GunBound. It's funny how trying to get infinite gold or a perfect aimbot in a multiplayer game was the ultimate gateway drug to learning memory management, pointers, and assembly for an entire generation. The OS targets change, but the thrill of manipulating a running process remains exactly the same.
I never understood how people use compiled languages for video games let alone simple GUIs. Even though I'm now competent in a few, and I have LLMs at my disposal, I fall back to electron or React Native just because it's such a pain in the ass to iterate with anything static.
Native devs: what are your go to quality of live improvements?
what does compilation have to do with iteration speed? There's a lot of ways to get a similar feedback loop that youd get in something like react, like separating out your core gameplay loop into its own compilation unit / dll and reloading it on any changes inside your application
re, iteration: Have you encountered ImGui [0]? It's basically standard when prototyping any sort of graphical application.
re, GUIs in statically typed languages: As you might expect, folks typically use a library. See Unreal Engine, raylib, godot, qt, etc. Sans that, any sort of 2D graphics library can get the job done with a little work.
You might also take a look at SwiftUI if you have an Apple device.
Often use dynamic/scripting languages to improve iteration on gameplay code, even if a lot of the fundamental underlying code is native. And add dev-time hot reloading wherever we can so when you change a texture, it reloads ≈immediately without needing to so much as restart the level. We exile as much as we can to tables and other structured data formats which can easily be tweaked and verified by non-coders so we're not a bottleneck for the game designers and artists who want to tweak things, and make that stuff hot-reloadable if possible as well.
We also often have in-house build server farms full of testing code, because it's such a pain in the ass to iterate with anything dynamic. After all, games are huge, and sufficient testing to make sure all your uncompiled unanalyzed typecheckless code works is basically impossible - things are constantly breaking as committed during active development, and a decent amount of engineering work is frequently dedicated to such simple tasks as triaging , collecting, and assigning bugs and crash reports such that whomever broke it knows they need to fix it, as well as allowing devs and designers to work from previous "known good" commits and builds so they aren't blocked/unable to work on their work - which means internal QA helping identify what's actually "known good", hosting and distributing multiple build versions internally such that people don't have to rebuild the universe themselves (because that's several hours of build time), etc.
Some crazy people invest in hot-reloadable native code. There's all kinds of limits on what kinds of changes you can make in such a scenario, but it's entirely possible to build a toolchain where you save a .cpp file, and your build tooling automatically kicks off a rebuild of the affected module(s), triggering a hot reload of the appropriate .dll, causing your new behavior to be picked up without restarting your game process. Which probably means it'll immediately crash due to a null pointer dereference or somesuch because some new initialization code was never triggered by the hot reloading, but hey, at least it theoretically works!
And, of course, nothing is stopping you from creating isolated sandboxes/examples/test cases where you skip all the menuing, compiling unrelated modules, etc. and iterating in that faster context instead of the cumbersome monolith for most of your work.

Having a faster build step helps: I just stepped back into C recently, and I don't even want to imagine doing it without ccache and meson.
