So can anybody please explain the problem.
As per your question your build crashes on iPad Air and running on all other iPad. As we know iPad Air is a 64 bit device, it might possible that you haven't set the Valid Architecture for 64bit. So, you have to check it in your Build Settings -> Architecture -> Valid Architecture (arm64, armv7, armv7s).
Might this will solve your problem.

I am having a crash only on one specific scene in my AR Foundation Unity build with the following error.

At first I thought it was because I was missing the Environmental Probe manager in that scene (no). Then I thought perhaps it was because I was using a specific shader that didn't use a _MainTex. But I use that shader no problem in other working scenes.
And then I built the scene with only a simple primitive and my UI and still received this error. After that crash the scene did open successfully, but obviously the problem is still there. The UI is the exact same as the other working scenes.
I can't find out much about this specific error: TexturesMetal::AddCreatedTexture - only that there may be this bug with GLES3 and PVRTC textures - but they aren't present in the most recent build.

The scene works perfectly in Android - it only crashes in iOS.
Any ideas? Full report below.

I'm seeing a segfault from using NSLog and specifically, it is on a 64 bit device, with a SEGV_ACCERR. I'm new to iOS, so i'm a little confused.

Here is the code that calls this:
NSString *truncated = [NSString stringWithUTF8String:buffer];
// Using original NSLog to print.
#undef NSLog
NSLog(#"%#", truncated);
and it crashes from my NSLog call.
where buffer is just a char buffer.
My questions specifically are:
Is it even possible to crash from using Apple's provided NSLog? Or is my stack trace wrong?
What does SEG_ACCERR even mean in this context?
How could i go about finding if this was caused by a bad memory issue or not?
Is something blowing up with the asl file under multiple threads?
How should i approach debugging this?
Any help would be greatly appreciated! Thanks!
You say that buffer is a char buffer. If that is the case, you should initialize the string like this
NSString *truncated = [[NSString alloc] initWithBytes:buffer
length:len NSUTF8StringEncoding];
where len is the length of the characters in the buffer.
We have a repeating crash when initilizing Speechkit.
It only happens sometimes on both iOS7 & iOS8 and we could not identify a specific scenario.
We were using ver. 1.0.3 and upgraded to 1.4.12. This issue happens in both versions.
The trace looks like:

I am experiencing out-of-memory crashed with my app on iOS on both iPhone 6 and 5s. I am sure that memory is the problem, because I receive memory warnings and also because of the crash log.
In the app I do video processing and process around 400 images in 10 seconds for one post-processing step. Each frame's resources get properly released in an autorelease pool. The crashes come after a random amount of repetition.
I allocate a lot of memory during those 10 seconds (a few hundred MB) in total, but the memory gets released after each processed image, due to the custom autorelease pool.
However, when I try to profile the root of the problem, I can not even detect high memory consumption, let alone search for the source of the problem. I have analyzed the used physical memory in the activity monitor in Instruments and neither my app nor mediaserverd consume more than 30 MB at any given moment.
Why do I get memory crashes, when my app is only using 30MB of memory at peak? How can I measure and debug the memory consumption correctly?
Any pointers a greatly appreciated!
Here is a screenshot of the memory report at runtime:

Here is the code for one of the effects I am using (renderAnimation2DOverFace does not allocate any memory):
- (CIImage *) render:(CIImage*)targetImage imageContext:(CIContext*) imageContext
facialFeatures:(NSArray*)facialFeatures currentFrameInd:(int)frameInd
{
if ( !facialFeatures ) return targetImage;
#autoreleasepool {
UIImage *editingImage = [[UIImage alloc] initWithCIImage:targetImage];
UIGraphicsBeginImageContextWithOptions(editingImage.size, NO, 1.0);
[editingImage drawInRect:CGRectMake( 0, 0, editingImage.size.width, editingImage.size.height)];
for ( ArtechFacialFeature *facialFeature in facialFeatures ) {
[self renderAnimation2DOverFace:facialFeature.bounds
currentFrameInd:frameInd];
}
UIImage *resultImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
targetImage = [targetImage initWithCGImage:resultImage.CGImage options:nil];
editingImage = nil;
resultImage = nil;
}
return targetImage;
}
This is another video effect routine:

When in a loop doing processing that uses autoreleased memory you need to put an autorelease pool inside the loop. Note that many Cocoa and Foundation methods use auto released memory.
The problem is that each operation is retaining and auto-releasing memory but the memory is not actually released until the current autoreleasepool is drained, usually in the run loop and that is not being called because of the tight loop.
Example:
for (...) {
#autoreleasepool {
perform work
}
}
You can put an autoreleasepool around smaller parts of the operations.
To debug reduce the loop count so you don't crash and then use Heapshot:
Use instruments to check for leaks and memory loss due to retained but not leaked memory. The latter is unused memory that is still pointed to. Use Mark Generation (Heapshot) in the Allocations instrument on Instruments.
For HowTo use Heapshot to find memory creap, see: bbum blog
Basically the method is to run Instruments allocate tool, take a heapshot, run an iteration of your code and take another heapshot repeating 3 or 4 times. This will indicate memory that is allocated and not released during the iterations.
To figure out the results disclose to see the individual allocations.
If you need to see where retains, releases and autoreleases occur for an object use instruments:
Run in instruments, in Allocations set "Record reference counts" on (For Xcode 5 and lower you have to stop recording to set the option). Cause the app to run, stop recording, drill down and you will be able to see where all retains, releases and autoreleases occurred.
The problem was that there was a CIImage which was de-referenced outside of the autoreleasepool and outside of the render methods, which I have posted in the question.
It is the targetImage parameter that is being passed as an argument. So now I added another autorelease pool outside of the method call and that fixed all my memory problems.
It still is a mystery to me though why those unreleased allocations of the CIImage did not manifest in the amount of memory used in the memory monitor and other tools.
Also, I do not understand, why the crashed would only happen occasionally.
i am doing one application.That application is running successfully in ipad simulators.But app was crashed in ipad retina simulator without any exception or error message.And the crash report for that crash is
