Is reverse engineering a problem if you write whole game in Swift?

[Qws]

Apparently it takes almost no effort to reverse engineer a Godot game relying on GDscript, but also a very little effort to reverse engineer a .NET Godot game.

I have interest in SwiftGodot, simply because I want to learn Swift and I think a game engine that doesn't use garbage collector is a very good thing. But I'm curious how reverse engineering state is with SwiftGodot? Is it harder or just as easy? Or does it depend on the platform?

languages that compile to native code like swift or c are harder to reverse engineer than interpreted languages or systems like c# and Java that use bytecodes that are both easy to decompile and have a good ecosystem of decompiling tools.

But it is not impossible, merely harder. Swift is harder than C in a few dimensions, existing professional decompilers for c/c++ have not been updated to deal with swift-isism, so it is even more obnoxious.

But in the end, decompilation for all languages is possible, it is just a matter of how hard someone really wants to get at the data and how much they are willing to invest in it.

overall, I think that swift and other compiled languages like c/c++ will be beyond the means of casual observers that could have cracked trivially a gdscript or c# program, but it is by no means impenetrable.
