How can an instance KVO its own and super's attributes, especially with overrides?

I’m writing an NSOperation subclass. Instances are dumped into the main queue, but I hope I stop them from executing right away by overriding -isReady. But the docs say I have to keep the override KVO-compliant. And my formula for the new -isReady uses the old one. Can I observe on super? Withou

This works: private func shiftArray( inout arr: [UInt32], lowerIndex: UInt, upperIndex: UInt ) { // move: arr[ lowerIndex ..< upperIndex ] to: arr[ lowerIndex + 1 ... upperIndex ] let av = arr[ Int(upperIndex) ] for v

We've developed a Photo Editing extension to edit user's photos. But the photos which user take havelarge high-resolution. When editing them in extension, it will cost about 100-200MB memory and extension get crashed. But we can't reduce user photo's resolution, how to apply more memory in Phot
