Almost all of the time, if there's a bug, it's Your Fault™. But sometimes, it really is a bug in the API/OS. As iPhone OS is relatively new (especially 3.x) there are always a few bugs to look out for.
I think it would be a good idea to compile them in a list. If you know of any, please list them, along with which versions are affected, and if applicable any known workarounds.
It might save someone from pounding their head on their desk out of frustration when they're just experiencing an OS bug.
One good resource to look at is open Radar (http://www.openradar.appspot.com) It is a site where people publicly post the bugs they have filed with Radar (Apple's closed bug tracking system)

I would like to customise App Suggestions in iOS programatically.
It usually says Good Morning and my app name.
Is it possible that I configure it to say something other than "good morning"?
Can I control when and where it appears?
I couldn't find much information in this regard.
Thanks,
Elstine
You can't modify App Suggestions from an application, as that content is outside of the scope of an app's sandbox.
"Good Morning" appears there because the App Suggestion feature detected that you usually use a particular app in the morning and greets you with an according message. Those strings come directly from this feature and are not app-dependent; therefore, they can't be changed as of now.

Not really a programming question, but this topic needs an up to date discussion for all the newbies outthere. I've googled but didn't find anything useful. So, do you need to know ios 7 if you want to program for ios 8? Is iOS 8 just a extension and everything in programming for iOS 7 is also valid in iOS 8? There are many books on iOS 7(not so much on iOS8), but it would be a waste of money to buy out of date books.
Thanks for answering
IMO:
you don't really have to know the past of iOS... only when you want to support lower OS versions and even then you only need to know what changed in that area / what you need to change
said that though: it doesn't hurt to have a general foundation. ;) generally :D

There is plenty of info about all the problems with SKShapeNode in iOS 7.
Memory Leak in Sprite Kit Application
http://sartak.org/2014/03/skshapenode-you-are-dead-to-me.html
Have all these issues actually been resolved in iOS 8? There aren't any posts later than August 2014 describing problems, but I wanted to make sure before I committed to SKShapeNode.
Update:
According to LearnCocos2D you probably shouldn't use SKShapeNode for serious games. However, from inferring from what I've been reading, and from my (brief) experience, SKShapeNode won't cause any memory headaches during casual use. I'm inclined to assume this is true, unless anyone has information to indicate otherwise?

I am now finishing my first app I developed in Xcode.
Now i want to improve smoothness of my app. Sometimes my app freezes for really short time. If you would played it for first time, you wouldn't noticed, but for me it is a nightmare.
Maybe my sounds causing that problem (i am running them on different thread but anyway), or something else..
What is the best way to test my app? Are there some special programs to do it?
First thing you can do in Xcode: Product -> Scheme -> Edit Scheme -> Build Configuration -> Release.
If you e.g. work much with arrays, it will speed up your app.
You can then also use Instruments to test the behavior of your app.

So far I have been suggesting new features to http://delphi.uservoice.com
Since it is managed by Nick Hodges (who is no longer an employee of Embarcadero) I decided to report my future improvements requests to http://qc.embarcadero.com
Is QC this the right way to go or is there a dedecated Idea Share solution I am not aware of?
Just as a reference I will point one of my suggestions Add Patterns.pas to allow easily document code
Please advise which is best place to submit such stuff to?
QC is the only official place for end users to report bugs or make suggestions. While alternatives like uservoice might be nice I'm not aware of any Embarcadero employees actively monitoring that site.
