iOS 8 setValuesForKeysWithDictionary fails on iPhone 5 / iPhone 4s
One issue that could arise is if you had your properties mistyped when you were deserializing from JSON. I am fairly confident that the 64-bit runtime will automatically convert a string to an int but the 32-bit runtime will not.
Why does the following code crash on an iPhone 5 but not an iPhone 5S?
The Int integer type is a 32-bit integer on the iPhone 5 and a 64-bit integer on the 5S. Since arc4random() returns a UInt32, which has twice the positive range of an Int on the iPhone 5, your first version basically has a 50% chance of crashing on this line:
var index = Int(arc4random())
Your modified version waits to convert until you take the modulo sum with max, so it's safe to convert to Int there. You should check out arc4random_uniform, which handles the modulo for you and avoids some bias inherent in your current implementation.

This is working on all version like iOS 6, iOS 7 and iOS 8 etc...

What's the device code (platform string) for iPhone 5 / 5c / 5s / iPod touch 5?
You can find a list of all iOS device identifiers here (including iPhone 5 models and iPad mini):
http://theiphonewiki.com/wiki/index.php?title=Models
The identifiers of the latest models are:
iPhone 5: iPhone5,1 and iPhone5,2
iPhone 5C: iPhone5,3 and iPhone5,4
iPhone 5S: iPhone6,1 and iPhone6,2
iPhone 6: iPhone7,2
iPhone 6 Plus: iPhone7,1
iPhone 6S: iPhone8,1
iPhone 6S Plus: iPhone8,2
iPhone SE: iPhone8,4
iPhone 7: iPhone9,1 and iPhone9,3
iPhone 7 Plus: iPhone9,2 and iPhone9,4
iPhone 8: iPhone10,1 and iPhone10,4
iPhone 8 Plus: iPhone10,2 and iPhone10,5
iPhone X: iPhone10,3 and iPhone10,6
EDIT: I also made an updated version of the popular iOS Support Matrix including all models up to iPhone X.
iOS 8 screen bounds different on device and simulator in landscape orientation
I have managed to resolve this myself as below. This works for all current iPhone/iPad devices running iOS 8 where the app is set to run in landscape mode only. Not sure why the code I originally posted doesn't work.
CGRect screenBound = [[UIScreen mainScreen] bounds];
CGSize screenSize = screenBound.size;
if (screenSize.width > screenSize.height)
{
ScreenHeight = screenSize.width;
ScreenWidth = screenSize.height;
}
else
{
ScreenHeight = screenSize.height;
ScreenWidth = screenSize.width;
}
App not installing on iPhone 5s
No there is not need to use the iOS 7 SDK, all iOS 7 devices are capable of running iOS 6 apps.
Just make sure that you have the correct UDID, if the UDID start with FFFFF the UDID is not corrcet. Since iOS 7 the developers can not access the UDID any more. Thus all the UDID app are not longer working.
You should use iTunes to retrieve the UDID of the device.
