Honest question, because I really am curious. I've no coding experience and I'm left wondering. I'm sure that it depends on the app and there's no universal answer. But on average, could it be a couple days' work? A week or so? I ask because I'm tired of seeing apps deleted from the store because they're no longer compatible with the latest OS. Or downloading an old favorite and finding that it crashes every time (Crash Bandicoot Nitro Kart, I see you living up to your title, denying me my nostalgia trip). For me personally, with iOS 7, it was the game "Mensa Academy" that sticks in my mind as being pulled due to incompatibility. Now with iOS 8 apparently, it's Lara Croft: Guardian of the Light. Both of these titles are from Square Enix. So now I know to not buy any other apps from them in the future. Thankfully I'm not into RPGs/Final Fantasy things. Of course there's a world of other examples of apps that have been pulled due to age and developers not wishing to keep them up to date any longer. Sometimes they give fair warning, and that's nice enough. But I'm left to ask -- Is it really worth burning your customers when and if you or your company really could have the time and resources to make some tweaks? Or in some cases, is it really, truly, waaaay too much to deal with? Big thanks to anyone who wants to help me understand.
