I'm trying to determine the best practice for handling if Image Playground is available but not installed or simply not supported. If ImagePlaygroundViewController.isAvailable is true, I will just display a button to start an Image Playground session. If it is false, does that mean ImagePlayground is supported but not installed? If it's supported and not installed, instead of a button to launch it, I want to display something like "Enable Apple Intelligence in Settings" or, better yet, a button that opens the Intelligence settings. Is that possible? But if it is on a system that doesn't support it, of course, I don't want to instruct the user to enable it. How can I determine if a device cannot install Image Playground? I read that Apple Intelligence requires iPhone 15 Pro, iPhone 15 Pro Max, and all iPhone 16 models, and no mention of the M1 iPad Pro, yet Image Playground runs on my M1 iPad Pro. What are the hardware requirements for Image Playground?

If I change MKMapView's .preferredConfiguration property from .realistic to .flat, or .mapType from .hybridFlyover to .hybrid, subsequent scrolling causes a crash: -[MTLDebugRenderCommandEncoder validateDrawIndexedPrimitives:indexCount:indexType:indexBuffer:indexBufferOffset:instanceCount:function:]:6179: failed assertion `Draw Indexed Primitives Validation indexBufferOffset(0) + (indexCount(864) * 2) must be <= [indexBuffer length] (12). For example, changing: mapView.preferredConfiguration = MKHybridMapConfiguration(elevationStyle: .realistic) to: mapView.preferredConfiguration = MKHybridMapConfiguration(elevationStyle: .flat) Then, scroll the map view, and it will crash. It is OK the other way around. Or change: self.mapView.mapType = .hybridFlyover to: self.mapView.mapType = .hybrid I've tried everything I can think of, including calling functions like these after the change: mapView.setNeedsDisplay() mapView.setRegion(self.mapView.region, animated: false) .mapType and .preferredConfiguration are settable properties, so they should be possible to change. I could create a new MKMapview, but I'd have to perfectly recreate the state which is not trivial and far from ideal. I'm just trying to work around the issue FB14553276 so my map tiles don't show tiling seems in 2D which is a new issue introduced with iOS 18. This potential workaround still shows the seems in 3D, but is better than always showing seems. Seems like whatever I do, I just can't defeat MapKit bugs and puts me in an impossible situation. :( I've submitted Feedback this issue: FB16153802 It seems like others are experiencing the issue: https://forums.developer.apple.com/forums/thread/730780

When I run the performance test on a CoreML model, it shows predictions are 834% faster running on the Neural Engine as it is on the GPU. It also shows, that 100% of the model can run on the Neural Engine: GPU only: But when I set the compute units to all: let config = MLModelConfiguration() config.computeUnits = .all and profile, it shows that the neural engine isn’t used at all. Well, other than loading the model which takes 25 seconds when allowed to use the neural engine versus less than a second when not allowing the neural engine: The difference in speed is the difference between the app being too slow to even release versus quite reasonable performance. I have a lot of work invested in this, so I am really hoping that I can get it to run on the Neural Engine. Why isn't it actually running on the Neural Engine when it shows that it is supported and I have the compute unit set to run on the Neural Engine?

Ever since switching to an M1 Mac for my development, Xcode no longer shows any image previews at break points. Quick Look is not functioning with any images: CGImages, UIIMages, CIImages, MTLTextures, etc. I am working on an image-based app, so this is extremely frustrating. I am running in debug mode. I tried linking to images to show some screenshots but apparently they are not allowed on this forum. Xcode 12.5 macOS 11.3
