The following code works fine on iOS 8, but when launched on iOS 9.0.2 I get some odd results:
NSString * input = @"Hi there";
NSData * data = [input dataUsingEncoding:NSASCIIStringEncoding];
Byte *byteData = (Byte*)malloc(data.length);
memcpy(byteData, [data bytes], data.length);
NSString * result = [NSString stringWithCString:(const char*)byteData encoding:NSASCIIStringEncoding];
NSLog(@"Result: %@", result);
iOS 8.4 (iPhone 6 Plus) byteData-Hi there
iOS 9.0.2 (iPhone 6S) byteData-Hi there\xb6<M\x13
In iOS 9, I end up loading garbage at the end of the line.
This seems like a problem with 32-bit and 64-bit versions, since on iOS 9 the data byte length is twice as long?
Apple has a table from 32 to 64 bits:

data.length unsigned long long. malloc? 8 data.length iOS.

NSString * result = [[NSString alloc] initWithBytes:byteData length:data.length encoding:NSASCIIStringEncoding];

NSString * result = [NSString stringWithCString:(const char*)byteData encoding:NSASCIIStringEncoding];
