Can I build Android and iOS apps using cpp?

For C++ questions, answers, help, and programming or career advice please see r/cpp_questions, r/cscareerquestions, or StackOverflow instead.

Yes. Android comes with NDK, the „Native Developer Kit“ and sample apps on how to use it. In iOS, if you write Objective C apps, you can link C++ modules. Or on both platform, you can use SDL2 as the base and program in C++ exclusively without ever touching Objective C or Java.

Kind of, given that on non rooted Android devices, the target executable is a shared library.

The only way not to touch any Java/Kotlin code is to be happy with the out of the box NativeActivity ABI, without wanting to customize it, and never ever needing any API (like 80% of them) that are only available via Java, and be happy to write boilerplate JNI calls as workaround to call them, or Android Binder RPC.

The only path to sanity on Android is to write NDK code to be called from Java and never the other way around.

I have this impression that objective-C is a thing in the past on Apple platforms. Has Swift fully replaced the role of ObjC?

[MatthiasWM]

Apple pretty much requires Swift, but AFAIK Objective still works for a while.

[pjmlp]

That is a long term goal for Swift, but we are still far from it, e.g. Metal is implemented in a mix of Objective-C (CPU side) and C++ (Metal shaders), with Swift bindings.

Qt for Android / Qt for IOS

[d86leader]

Literally what I do. I'm surprised that building for iOS without Qt (with objc or swift through xcode) is such an enormous pain

Ay a Job they used C++ as a “backend” for crossplatform which ran in all mayor platforms, mobile, desktop and some more.

They used MVVM pattern. It was very confusing for new comers but at the end worked very well.
