column

It’s confusing in your description. You‘ve got a hundred row table, data from tile_1_1 to tile_10_10, “given” and current values. Do those tiles run from _1_1 to _1_10, then _2_1 to _2_10, etc?You can do two-dimensional data in a database, it’s just usually seen as a bit of overkill. You could define a DataTile entity asRow: intColumn: intgiven valuecurrent valueand then specify row, column as the unique index values so you don’t have to worry about collisions and get a better sorted result.Then you could do your fetch request on DataTile, for dataTypeSort specify row and column as the keys for the sort descriptors, and that’d given you something you could loop over easily. (Especially since you can get the results grouped by row if you want...)If your row,column data is irregular (some rows have more or fewer columns), the database doesn’t mind.

what is the DeviceAnchor? Is it the location from which virtual content (and camera passthrough) is rendered on the user's display(s)? My understanding of a 4 by 4 transformation matrix is that the last column represents the translation, while the first 3 columns represent the local x, y, and z axis. I have plotted the first three columns of the extrinsics matrix and they do not seem to be orthogonal to each other, what are the implications of that? I would expect just a translation and a rotation (without scaling/shearing) what is the coordinate system for these intrinsics? based on the first 3 columns, it seems to be x=right, y=down and z=forward. Is that correct? any help or link to well-written documentation very much appreciated. When I see the following documentation which only tells me the type of extrinsics, and literally nothing else than just the type, I find that insufficient. https://developer.apple.com/documentation/arkit/cameraframe/sample/parameters/4443449-e

If you look at Quinn's example:let sheet: [[Int]] = [ [1, 2, 3], [4, 5, 6], [7, 8, 9], ]and compare it to a spreadsheet, it would look like this: A B C 1 1 2 3 2 4 5 6 3 7 8 9 If we add a 4th number to each row, the spreadsheet would look like this: A B C D 1 1 2 3 95 2 4 5 6 96 3 7 8 9 97which would correspond to:let sheet: [[Int]] = [ [1, 2, 3, 95], [4, 5, 6, 96], [7, 8, 9, 97], ]Columns are vertical, but there are no real columns as in a spreadsheet. Instead, every row contains all numbers in the row. It is still easy to get a certain cell (or element, as we call it), since you first get the row you want and then get the column you want from that.There is no limit per row of code, but the second column of the first row will always be the same, even if you add numbers at the end of the row.One thing to remember is that in Swift (and most programming languages), rows and columns start on 0, while they start on 1 in most spreadsheets. Is this what confuses you?

Great, thank you @sha921 ! However, the first column will not have the same size as the others. Any way to do this?

I have been given an api which outputs the followingYou should better add how you have output that JSON, which prevents some sort of easy misunderstanding.I assume it is the whole response from your API.And with pretty-printed: { statusCode: 200, headers: { Access-Control-Allow-Origin: * }, body: [ { ID: 29, ColumnAID: 12, ColumnB: Blah, ColumnC: , ColumnD: Not Listed, ColumnE: null, ColumnF: null, lat: null, lon: null }, { ID: 22, ColumnAID: 12, ColumnB: Blah, ColumnC: , ColumnD: Canberra, ColumnE: ACT, ColumnF: null, lat: null, lon: null }, { ID: 24, ColumnAID: 12, ColumnB: Blah, ColumnC: , ColumnD: Bondi Junction, ColumnE: NSW, ColumnF: null, lat: null, lon: null }, { ID: 25, ColumnAID: 12, ColumnB: Blah, ColumnC: , ColumnD: Broadway, ColumnE: NSW, ColumnF: null, lat: null, lon: null }, { ID: 26, ColumnAID: 12, ColumnB: Blah, ColumnC: , ColumnD: Castle Hill, ColumnE: NSW, ColumnF: null, lat: null, lon: null } ] } Outlined:{ statusCode: 200, headers: {...} body:

I’d like all columns to have the same size. (Without providing an explicit, fixed size.)

Drag/drop from where, to where, exactly? Finder to storyboard, resource column to asset catalog? ...?

Thanks so much, your first works great for me... But, how can I do the next step ? When I tapped on Landschaften that will be shows me Landschaften... That's nice. How can I do it for Maritimes? When I Tapped on Maritimes then I will that shows me Maritimes images... Can I drop more NavigationLinks in ContentView ? Have many Thanks ;) import SwiftUI struct ContentView: View { var columns = [GridItem(.adaptive(minimum: 160), spacing: 5)] var body: some View { NavigationView { ScrollView { LazyVGrid(columns: columns) { ForEach(ImagesList, id: .id) { images in NavigationLink { LandView() } label: { ImageCard(images: images) } } } .padding(10) } .navigationBarTitle(Text(Übersicht)) } .navigationViewStyle(StackNavigationViewStyle()) } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }

Thank you for following up! For this specific problem, I'm wondering whether you need this column. For an interval schema like this (I'm assuming you are using an os-signpost-interval-schema here?), there is already a duration column that Instruments will generate for you. It will contain the duration in nanoseconds, but upon display in the UI, Instruments will format it into a reasonable unit (so e.g. 1,700,000 would be displays as 1.7ms). So maybe you can use the duration column as a workaround? In any case, if this bug is still happening to you, can you please file a bug report via Feedback Assistant? Please make sure to include an .instrpkg file with your schema + instrument definition that compiles, so we can check whether the problem maybe resides in a different part of the code.

Did you find the solution for that issue? How did you made the first column as sticky header in SwiftUI?

This worked for xcode - 12.2 beta and IOS 14.2 Untick Debug executable from below paths worked for me. Product -> Scheme -> Edit scheme -> Select Run (left column) -> untick Debug executable Product -> Scheme -> Edit scheme -> Select Test (left column) -> untick Debug executable Then close and run again.

OK, just for future reference, we call that the Comments column in Finder’s list view. There’s certainly no API to manipulate Finder views. On the AppleScript front, it seems like Finder has infrastructure to support this. For example: tell application Finder set visible of column comment column of list view options of Finder window 1 to true end tell Unfortunately I can’t get it to work. When I run the above on my machine (running 12.3.1) it doesn’t error but it also doesn’t do anything )-: Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

I would check the value of rowBytes(fromColumns:dataType). You're currently assuming it is columns*sizeof(float) but the docs for MPSMatrixDescriptor say: For performance considerations, the optimal row stride may not necessarily be equal to the number of columns in the matrix. The rowBytes(fromColumns:dataType:) method may be used to help you determine this value.If this row stride is different between the different GPUs you've tried, that would explain the error.

This is something I've been struggling with for some time. The hierarchy of my app makes this harder to diagnose. But like you, it was working fine for years. In my case, this app supported three column-layouts prior to the release of column-based split views. In order to do so, we have a concept of a NestedSplitViewController -- which is a UIViewController that owns a UISplitView. We're running into the same issue with Xcode 15 – and can't seem to pin it down.
