This issue: Unity Issue Tracker - [AntiAliasing][iOS] Crash in UnityBlitToBackbuffer when AntiAliasing is on
Says it’s resolved in 5.2, I just did a build using 5.2.0f3 and it’s still crashing with anti aliasing on (in
UNITYBLITTOBACKBUFFER )
I’ve just tried this with 5.2.0f3 (e7947df39b5c) and didn’t get any crashes with GLES2/2 or Metal. What device are you using?
For me, Anti Aliasing issue was gone but i get in trouble with ETC2 format. Xcode 7 beta mention that isn’t supported.
Hey _Paulius, I specifically tested on an iPad4 with iOS 7.1, using XCode 6.4 (6E35b), Auto Graphic API was turned on. This was with Anti Aliasing set to 4X Multi sampling

GoFe, ETC2 is currently not supported and it shouldn’t be possible to use it on any textures when building for iOS.
CPXTom, I don’t really have an iPad 4 with iOS7 currently at hand, but I’ve tried it on several similar devices running iOS7. Just to be sure
Version 5.2.0f3 (e7947df39b5c)

Branch: 5.2/release
is this the build you are using?
Yes, that is the version I am using.
It appears to be working on an iPhone 6 running iOS 8, but is not working on an iPad 4 running iOS 7.1 (11D167) or an iPad Air running 7.1.1 (11D201).
I can provide a full stacktrace, but I’m fairly certain it’s the same as before.
Could you submit a bug report with your Unity project (and also attach the Xcode project) and send me the case id? Might be that we are using different quality settings (or something like that) to test this.
Our Unity project is pretty big. I’ll see if I can repro the issue in an empty project first, with the same settings I’m using in our project. I’ll see if I can get to that some time later today!
Same issue here. iPad 4, iOS 8.1 building with Unity 5.2 and Xcode 6.4.
I used 8x AA and 768P resolution, and my build crashed (UNITYBLITTOBACKBUFFER)
If I just turned the resolution to Native the project would run with no problem 
Looking for an fix soon!
It turns out that in 5.2.0f3 AA was only fixed for Native resolution. And the full fix, for all resolutions, was only merged into 5.2.0p1. It which should be available later this week.
