Hi!
I updated my iPhone to iOS 8 and downloaded Zen Garden to finally test it, after download, I launch the app, the UE4 black screen appears and after a few seconds it closes automatically, no messages, just back to home screen.
I’m using a iPhone 5S and it has a few GBs of avaliable space, closed all apps running but didn’t helped. Tried re-install and re-start my device, didn’t worked 
Can you guys help me with this?
Kind Regards.
I’m also having the same issue on my ipad 4. Start app -> unreal engine logo -> app crashes / goes to homescreen.
CyberWolf - It will not run on iPad 4, it does not have an A7 chip. There is an issue with the App Store where it is allowing Zen to be downloaded on devices with A6 processors (it is being
CyberWolf, iPad4 is not actually supported. There is currently a bug with Apple App store that is allowing apps that require the ability to use Metal to be downloaded to non-Metal devices. , I’m not sure why you are crashing. I’ll have our QA here check on several devices and see if we can repro.

Hi guys! Thank you for the reply.
Yeah, that’s really weird, should really run without problems but looks like I’m not with a great amount of lucky these days hehehehe
Anyway, I got the crash files that maybe can help you guys. It’s here - UE4 Zen Garden Crash - Pastebin.com - I don’t understand nothing about what is being reported, so I’ll leave it to you guys, sorry.
That crash log helps immensely - it tells me you have a 5, not a 5S 
It is not supported on the 5, as that does not have an A7 processor.

Thanks! I’m sure this is documented somewhere, but if I could ask a potentially obvious question… Should we consider the iPhone 5S, iPad Air, and Mini w/ retina display, the minimum for Metal code? Or is the limitation more about the demo itself? I am not 100% familiar with Apple limitations for metal, and not sure if we should consider separate builds if for some reason targeting anything prior to the A7 processor. (I doubt we will target anything older, but just wish to be crystal clear on the question since as you’ve seen with reviews, it can have an affect on the overall rating if Apple doesn’t screen who’s downloading.)
If I could ask one more, any plans to make the Zen Garden download for UE4 as a demo? Just curious if I should keep an eye out for it.
Thanks!!!
Ohhhhhh! I was testing in the wrong iPhone, tested in the real iPhone 5S and it’s working properly. Sorry for the messy about that, I was confused by the App Store allowing me to download the app even with a device that doesn’t support it :S
@timconwell, as they said, only devices with A7 and above works with the device, at Apple Store it says iPhone 5S, iPhone 6, iPhone 6 Plus, iPad Aie, iPad Mini with Retina Display, the weird is that I was able to download it even with a not supported device 
Anyway, thank you guys, the demo is awesome!
Kind Regards!
timconwell: Metal only works on A7 and up devices. Apple has no plans (that I am aware of) to support A6 and lower. However, you can make a UE4 game that supports Metal and ES2, and it will choose which renderer to use based on the device and IOS version it’s running on. There are project settings to choose what you want to support. If you support both, there will be both sets of shaders cooked into the data files, so it will be somewhat bigger, depending on your material usage. You don’t need to make two separate builds.
: There is currently an App Store bug that is allowing people to download it on unsupported devices. Hopefully it will be fixed soon. We updated the description to help

I a having this same issue. Epic Zen Garden crashes immediately after the URE loading screen… i am running an iPhone 6 plus, with plenty of gb of extra storage. I don’t understand what the problem is. i have tried deleting it, restarting, and re-downloading. nothing works. help?

@hntyoung can you post the crash report like I did? They told me that this helps a lot to know what’s happening.
here’s the crash report. i hope i did this right.
Yes, that’s it. Now you just need to wait a bit until the devs look into your problem
I will try and get that callstack translated today We actually haven’t seen it crash at all, and it’s been running fine on the iPhone 6/6+'s we just got… so I am definitely confused, and I apologize that it’s not working!
Josh
any word on why it isn’t working?
