People are talking about "lag" and performance, as if this was a "the system can't handle it!" issue. This is a misleading description. The actual issue is that some developer at Apple screwed up their animation configuration when implementing the calculator redesign, and nobody tested adding more than two numbers together quickly. Multiple failures, none involving system performance. What's happening is: the operato…
Your solutions are a little off the mark. Treating the animation as the problem is merely treating the symptoms. What needs to happen here is pressing the button needs to immediately register the press elsewhere in the code. The UI animations and the button tap should be decoupled entirely. Then the user can tap away as fast as their heart desires and only the animations are going to continue on. That’s an easy probl…
This goes well beyond UI design, and there are even physical analogs - for example, the crash of Turkish Airlines flight 981 in Paris could have been prevented if the device to prevent the cabin being pressurized if the cargo door was not properly closed had been operated by the door locking pins sliding home all the way, rather than by a side-linkage off the linkage that was supposed to drive in the pins.
