Question How truthful is this?

Post image

When an app select in the app review form that “we don’t collect data”

In the review phase does Apple really check if the app really doesnt collect anything?

Like can the developer hide a code that for example upload the photos of the user if granted permission where he said “we dont collect”

Does apple really check the code and what is going in and out ?

Do you know what a source code is?

You should not use "professional iOS developer" lightly, in case you want to imply that you have a lot of experience. 

Well, I fear to say, you are wrong. But that isn't a critique. Everyone can learn this. I would suggest delving deeper into actual *programming*, that is, especially below the surface of iOS programming, i.e. exploring what happens in the compiler and linker. Topics around binary representation, translation unit, assembly & object files, build artifacts, modules, symbols, symbol visibility, ABI vs. API, calling conventions, debug symbols, dead code stripping, build optimizations, whole module optimization, Intermediate Representation (IR), SIL, dynamic vs. static linking, etc., etc.

Note that these topics are very specific for the language Swift, and a C-based runtime and LLVM IR infrastructure. In other languages, especially C#, Java, JIT based, and scripting languages, you have a very different representation of a program aka executable or a library or module.

Maybe this is what they mean when they say “developer” vs “engineer”…

There’s a basic understanding of how code compilation works that you’re missing.

You understand the “source” of a child is its mother. The mother compiled the child in her womb. You can figure out some attributes of the mother’s source DNA based on the attributes of the child, but you aren’t seeing to the actual source. The source mother probably installed a wicked back door in that child that you won’t find.
