I cannot install any widgets on my simulator, even the system provided ones. I just finished removing all dev software from my machine and reinstalling only Xcode 16.3. Springboard always crashes: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0xfffffffffffffff8 Exception Codes: 0x0000000000000001, 0xfffffffffffffff8 VM Region Info: 0xfffffffffffffff8 is not in any region.

I removed all the runtimes, every cache and preference I could find, emptied the trash, rebooted (to release any open file descriptors), and reinstalled Xcode. Nothing helped.

When I create a tab group for the sidebar on iPad, the title and disclosure triangle act like a single control. Every time I tap the section title, the disclosure triangle for that section activates and hides or exposes that section's children and actions. I want the section title to behave like Photos, where tapping a section title just displays its view controller, and the disclosure triangle is a separate control that must be tapped to hide and show children and actions. I did not see any delegate methods that would let me control this behavior. Is this supported?

I have a keyframe animation that animates an indicator in a control. Picture something like a speedometer in an arc where a pointer animates along the top. I set rotationMode on the animation to kCAAnimationRotateAuto and the animation itself works perfectly. When the animation completes, the pointer blinks back to a zero angle rotation. I want it to stay in the rotation it was in at the end of the animation. I tried using animationDidStop:finished: to set my layer's transform to the desired angle with layer.transform = CATransform3DMakeRotation(angle, 0, 0, 1) at the end of the animation which does set the correct rotation angle at the end of the animation, but then the animation itself has an incorrect rotation. I tried setting the layer's transform before the animation starts thinking the animation would animate to that value, but the animation was even more bonkers. Not sure what else to try. The rotationMode works beautifully, except for the end state.
