I never really got into low-level decompiling, examining machine code, or any advanced coding topics like that. When articles talk about code in iOS betas revealing upcoming features, what do they mean? I thought iOS was famously closed-source. How can someone get any details from any code?
@alexhall There's a kind of software called disassembler, used among other things to crack software. I don't know if a disassembler is used in the IOS case, though.
