I'm having trouble properly forming an argument to a type.

Here is my interface

I am trying to parse some JSON data with SwiftUI/Combine and I am a bit confused on the error I am getting. I am really new to Combine, so I could be completely overlooking something. I'm sure this has nothing to do with the real issue, as this would probably happen if I was parsing the normal way with urlsession/@escaping.

Here is the code:

I have a situation where my code needs to make one network call to fetch a bunch of items, but while waiting for those to come down, another network call might fetch an update to those items. I'd love to be able to enqueue those secondary results until the first one has finished. Is there a way to accomplish that with Combine?

Importantly, I am not able to wait before making the second request. It’s actually a connection to a websocket that gets made at the same time as the first request, and the updates come over the websocket outside of my control.

After examining Matt’s thorough book on Combine, I settled on .prepend(). But as Matt warned me in the comments, .prepend() doesn’t even subscribe to the other publisher until after the first one completes. This means I miss any signals sent prior to that. What I need is a Subject that enqueues values, but perhaps that’s not so hard to make. Anyway, this is where I got:

Initially I was going to use .append(), but I realized with .prepend() I could avoid keeping a reference to one of the publishers. So here’s a simplified version of what I’ve got. There might be syntax errors in this, as I’ve whittled it down from my (employer’s) code.

There’s the ItemFeed, which handles fetching a list of items and simultaneously handling item update events. The latter can arrive before the initial list of items, and thus must be sequenced via Combine to arrive after it. I attempt to do this by prepending the initial items source to the update PassthroughSubject.

Below that is an XCTestCase that simulates a lengthy initial item load, and adds an update before that load can complete. It attempts to subscribe to changes to the list of items, and tries to test that the first update is the initial 63 items, and the subsequent update is for 64 items (in this case, “update” results in adding an item).

Unfortunately, while the initial list is published, the update never arrives. I also tried removing the .output(at:) operators, but the two sinks are only called once.

After the test case sets up the delayed “fetch,” and subscribes to changes in feed.items, it calls feed.handleItemUpatedEvent. This calls ItemFeed.updateItems.send(_:), but unfortunately that is lost to oblivion.

At Oracle I would like to filter below TABLE as

my expected output is

Logic is Group by COLUMNA and COLUMNB (please evaluate below conditions on grouping.)

• if columnc candidate record (grouped by COLUMNA and COLUMNB) includes only PRIMARY take PRIMARY.
• if columnc candidate record (grouped by COLUMNA and COLUMNB) includes only SECONDARY take SECONDARY.
• if columnc candidate records (grouped by COLUMNA and COLUMNB) include PRIMARY and SECONDARY set, take PRIMARY.
• if columnc candidate records (grouped by COLUMNA and COLUMNB) include duplicate SECONDARY set skip record.
• imagine this row has 100 columns so I need to fetch row by itself. MAX MIN wont work here.

I have used couple of row_number() functions and where not exists but went into oblivion.

I'm going to post this question and answer tomorrow, as it's 2am here... So sorry in advance.

I'm web scraping from this particular page:Italian Website

What I'm having difficulty with is the scraping of information that is between tags that have been used many time, basically making them 1 in 1000.

Here is the part of code I need (I need the price):

I have a state in react called options that looks like:

Okay, I have to recode a df, because I want factors as integers:

I have three lists namely names, artists, and albums. I want to create a csv such that the first elements of each is in one row, and then next element in other and so on.

For eg.

I understand that this question has been asked to oblivion, but I havent been able to solve my particular issue with it.

When I started my project, I had cors error too, but after adding the following they dissapeared, until today I decided to refractore the code of an app, and it suddenly stopped working, fun fact is that the old code was working ok.:
