Reply to Metal Performance Shader color issue with yCbCr buffer
@DTS Engineer Thanks for the quick response. I'm not sure what the enhancement request would be other than maybe support for specifying on a MPS shader the pixelFormat so it knows how to handle it. Unfortunately the AVFoundation RGB format makes performance significantly worse - so we want to ideally decode natively. If I want to keep things decoded YUV - would the better performance be to convert to RGB in a shader then do the MPS Scale? Or just create two different MPS filters and use a bi-planar decode format. The bi-planar seems better for performance because I would need to encode back to a ProRes file quickly. Thanks, Joe

Reply to Safari, WKWebview Crash in iOS 15 Beta2
This new feature completely broke my app - which is a WKWebView with a large canvas. Performance is incredibly slow and renders the app useless. Worked great in iOS 14.. How can we disable this setting in a WKWebView? Why would it be that that canvases performed better on the CPU but Apple dropped that as the default and switched to GPU processing? Wouldn't the switch be to increase performance? Really concerned about the future of my app if we can't disable this 'feature'. Will the setting eventually go away and this will be the default?

Reply to SwiftUI : NavigationStack in new iOS 18 TabView pushes twice when path in parameter
Has anyone found a workaround for this? I cannot have a NavigationStack inside a TabView without it double pushing.

Reply to How to Convert a MTLTexture into a TextureResource?
Did you ever find a solution to this? I'm facing the same difficulty and there isn't much documentation on the DrawableQueue API.

Reply to TextField with trailing multilineTextAlignment does not show spaces
Having the same issue.. It's like the trailing whitespace disappears in the view until you type a character. Apple can you look at this? Should we file a bug report?

Same issue here on my M1 Mac mini. Works when testing under Rosetta. Super lame Apple!

Reply to Set minimum width for SidebarListStyle on macOS
I have the same issue. I don't want the user to hide the sidebar but can't figure a way to always keep it visible.
