None of the examples you pasted have anything to do with Apple’s garbage collector, hun. They’re just examples of advanced MRR.
As I already stated, the viewer has never used Apple’s garbage collector. It uses a combination of autorelease pools and MRR which is perfectly fine to do, especially in Objective-C++ where we are not only managing objective-c objects, but C++ objects as well. -- Cinder Roxley Sent with Airmail On July 8, 2016 at 1:47:16 PM, Geir Nøklebye (geir.nokle...@dayturn.com <mailto:geir.nokle...@dayturn.com> ) wrote: Cinder Roxley said: The viewer has never used the garbage collector so it?s not an issue. Why is it that in llopenglview-objc.mm, as en example, we have statement like: NSOpenGLPixelFormat *pixelFormat = [[[NSOpenGLPixelFormat alloc] initWithAttributes:attrs] autorelease]; or - (void)dealloc { [[NSNotificationCenter defaultCenter] removeObserver:self]; [super dealloc]; } while Apples ARC migration guidelines states: You cannot explicitly invoke dealloc, or implement or invoke retain, release, retainCount, or autorelease. You can’t invoke dealloc. Custom dealloc methods in ARC do not require a call to [super dealloc] (it actually results in a compiler error). The chaining to super is automated and enforced by the compiler. Or in llwindowmacosx-objc.mm we have code such as: bool copyToPBoard(const unsigned short *str, unsigned int len) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init]; NSPasteboard *pboard = [NSPasteboard generalPasteboard]; [pboard clearContents]; NSArray *contentsToPaste = [[NSArray alloc] initWithObjects:[NSString stringWithCharacters:str length:len], nil]; [pool release]; return [pboard writeObjects:contentsToPaste]; } Apple’s documentation specifically says how to rewrite this construct for ARC. https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSAutoreleasePool_Class/index.html#//apple_ref/occ/cl/NSAutoreleasePool So all this code needs to be rewritten to support ARC or it will not run or fail on 10.12.
