Just when I think I am finally starting to understand Swift I come across a gotcha like the following: I have two object, a swiftui display and one of data to be displayed. Ok, sounds easy. The data is read out of a JSON file so I have a set of arrays and dictionaries. The data is valid when read, it is definitely there, but when I go to display it, its gone. Just vanished. Wasted about a day on this so far, and I’ve seen it before, the inability to pass out of an object an array or dictionary with contents intact. If I create an array var, and not let the system do it, contents are preserved. So, in the data object I’ll have something like this: struct DataObject{ var item: [String:Any] item=JSONData serialized out of memory, and may have say, 12 fields } In my SwiftUI module I have: var item=dataObject.item dataObject.item now has 0 fields. I can allocate and initialize a dictionary in DataObject and those elements come through fine. So it seems like the stuff being serialized from JSON is being deleted out from under me.

I've been working on a project with App Intents and have hit a complete wall. The desire is to have an app that allows a person to place an order of something and have that order processed while in lock screen without any intervention. Is that workflow possible without having to unlock the screen? Under what circumstances can a task be handled without unlocking the device. Going over some of the documentation about older custom intents strongly implies that this was possible under certain circumstances.

I am in a weird twilight-zone of a git problem in xcode. I specify some files to be staged and it fails to do with no warning of any sort. So I cannot commit them or apply stashed changes to them. I can do it one.file.at.a.time. I have over 11k intermediate files that .gitignore won't ignore, nor stage nor commit to do anything so I could stop tracking them.

In prep for a push this evening did the usual clean and rebuild. But now I'm getting errors that it can't find files with .swiftdoc, swiftsourceinfo, and swiftmodule files. The few postings I can find about that said that reinstalling xcode fixed it, well , not i my case. Any ideas short of reconstructing the entire project from scratch?

I've been pouring over the code for Apple's visionOS demo: "Destination" trying to figure out something about its skybox. (not really a box, there, Apple). The skybox contains a 360deg panorama, but only one half shows with the other half fades out to nothing. I cannot find anywhere there is an alpha channel being set, a lighting or material effect causing that. But "alpha" doesn't show up and the only gradients are use to make controls standout a little more in its window. I need a full panorama that shows., no fading.

I have an iPhone VR app, but on the appstore page it says "Compatible with iPad". The full VR effect was only with the iPhone, but it's not showing that, nor is there any apparent way to set that in the metadata. So I am assuming that's automated. Any ideas how to fix it?

My startup screen (not using a formal splash screen) opens up and almost immediately jumps to the right about 50 pixels. Not sure if this is notch related but I suspect it is. Any ideas?

I recently released an update for one of my apps and am seeing precisely 0 updated downloads. I should be seeing thousands. I am getting sales, though.
