“column”

The Xcode editor allows for vertical cutting using option-click-drag, why does it not support vertical pasting? This type of feature can be very handy at times.

Greeting,I represent my matrix buffer with the following data on the GPU:Address: Data:0x00 0 1 2 30x01 4 5 6 70x02 8 9 10 110x03 12 13 14 15With the following shading code:float4 (out) = float4x4 (m) * float4 (in)According to apple's documentationfloat3 u = m * v;is equivalent to:u = v.x * m[0];u += v.y * m[1];u += v.z * m[2];My question is does m[0] refer to <0, 1, 2, 3> or <0, 4, 8, 12>?As my experiment shows the GPU does compute the matrix as m[0] = <0, 1, 2, 3>But common sense tell us m[0] should be the column <0, 4, 8, 12> otherwise it's very hard to read and debugIf m[0] did refer to <0, 1, 2, 3>, is there any way to transpose a matrix in shading file?Or we have to work on transposed matrix all the time?Thanks!

Hello everyone, I am experiencing a very weird issue. I have a simple relationship between 2 models, that occasionally starts crashing the app, with the following error: error: : Attempting recovery from error encountered during addPersistentStore: 0x282523c60 Error Domain=NSCocoaErrorDomain Code=134110 An error occurred during persistent store migration.

Hi, colleagues: I've spent days trying to understand this little SwiftUI layout problem, and I've made a minimal test app to explain it. It's based on a Content View of a fixed size. import SwiftUI @main struct TestApp: App { var body: some Scene { WindowGroup { ContentView() } .windowResizability(.contentSize) .windowToolbarStyle(.unified(showsTitle: false)) } } struct ContentView: View { let complaint = What's with the vertical space around me when I'm in a detail column? var body: some View { Text(complaint) .font(.title) .frame(width: 300, height: 300) .background(.blue) } } And here's the result. As expected, the Content View is hugged nicely by the window: My goal is to place a fixed-size view like this in the detail column of a Navigation Split View. So I update the scene's root view: import SwiftUI @main struct TestApp: App { var body: some Scene { WindowGroup { NavigationSplitView( sidebar: { }, detail: { ContentView() } ) } .windowResizability(.contentSize) .windowToolbarStyle(
