When I got started with CSS, there were a few pages that had all the basic examples - spacing subviews of a fixed size, spacing subviews with a certain amount of padding, etc. Basically given a list of subviews, what it would take to see the subviews displayed within the parent container.Before SwiftUI, Modern Auto Layout was a great reference into how UIKit managed views. There was a clear description of how the engine worked, and how the parent and child views were rendered.With SwiftUI, it's not clear to me. The API has pretty short explanations, and when I try different combinations, it seems like the modifiers overlap each other, and most I apply seem to have no effect at all, which brings me to the reason why I don't like CSS.Is there anything out there that goes into detail about how the rendering engine manages parent/child views, in the context of the modifiers?

I would like to save commands entered into a terminal instance for every console window I bring up. I am envisioning a directory that each time a terminal is opened a new file is created. As I enter in commands like ‘ls’ or ‘pwd’ it would write those commands to that file. Is there a way to do this? I would also like to write it to a database directly or web url through a POST if possible. Is there a way to add code snippets in a terminal window that takes action like this?

In the apple APNS docs, it says: ‘When you have a notification to send to the user’ how do I determine the device has reach a state where the user needs a notification from normal websocket reception? for instance, let’s say Johnny and Amber are arguing over chat. They each send each other 50 texts, which are received over websocket. Johnny then leaves his phone chat, how does the push provider server know that Johnny needs APNS notifications to be sent? note that I am not having issue with sending notifications, nor do I want to send notifications for every chat message. if the switch from websocket -> APNS isn’t consistent, I’ll have to request data from the server, which includes data prior to the notification, to make sure all messages are received. Is this the way it’s done?

I have in the past used TN2326 as reference to generate keys for our server that aren't self signed, instead signed by our certificate authority. The method in TN2326 is not working with the latest openssl, and honestly I don't understand these error messages enough to debug. If I add '-legacy' to the openssl command below - I do not get the error. However, clients using TLS are unable to connect to the server. In iOS, it reports a trust issue with the certificate, also pasted below. You can see below that I am using http3 with quic, so TLS 1.3 is important. I am running a python (3.10) script for the server, openssl I appreciate any help on this. % openssl pkcs12 -in server_192_168_0_187.p12 -nokeys -out server.crt Enter Import Password: Error outputting keys and certificates 4076BD4CF87F0000:error:0308010C:digital envelope routines:inner_evp_generic_fetch:unsupported:crypto/evp/evp_fetch.c:341:Global default library context, Algorithm (RC2-40-CBC : 0), Properties () From the iOS client using the '-legacy' option: task will start, url: https://X.X.X.X:4433 Connection 3: default TLS Trust evaluation failed(-9807) Connection 3: TLS Trust encountered error 3:-9807 Connection 3: encountered error(3:-9807) [connection] nw_connection_copy_connected_local_endpoint_block_invoke [C4] Client called nw_connection_copy_connected_local_endpoint on unconnected nw_connection [connection] nw_connection_copy_connected_remote_endpoint_block_invoke [C4] Client called nw_connection_copy_connected_remote_endpoint on unconnected nw_connection [connection] nw_connection_copy_protocol_metadata_internal_block_invoke [C4] Client called nw_connection_copy_protocol_metadata_internal on unconnected nw_connection Task <BA37397D-B6F1-46C0-8D1C-BC112FC82956>.<2> HTTP load failed, 0/0 bytes (error code: -1202 [3:-9807]) protocols: ["h3"] Task <BA37397D-B6F1-46C0-8D1C-BC112FC82956>.<2> finished with error [-1202] Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid.

Is there a way to capture video on the front facing camera (ie the selfie camera) on iPhone while using face anchors, left/right eye transforms for AR?

We've been using our app for the past year, and a user came back today that after three minutes, their phone starts getting hot and the screen dims. He is using 17.6.1 with an iPhone 14 max. No one else is seeing an issue, but with the posts online about 17.6.1 battery drain, I wonder if our AR app is somehow more sensitive to the issue.
