Apple has great developer forums at deforums.apple.com. I suspect most iOS developers go there when they need help. If not, they hang out at any of the dozens of developer forums that started back before the AppStore was created or in the years since. Further, iOS is a very well designed set of APIs that are very well documented by Apple with very extensive example code. I've asked a lot of questions about iOS, thoug…
I agree. A real data analyst or mathematician or anyone collecting survey data for that matter first must study the sample, not the output, which is what has been done in this case. The sample here is stack overflow which is a community of people looking to solve coding problems. There could be a few things at work here:
1. iOS devs hang out elsewhere
2. There are fewer iOS devs, who have tackled and solved the problems already
3. iOS devs don't need a community to solve problems
I'm not suggesting one or all of these are true, just saying these things need to be considered before positing a position based on data. Again, the sample defines the output in a much greater way than the data (e.g., if I survey 100 fisherman about whether they develop iOS apps, 100 will say no)
