I am trying to deploy our first Core ML model through the dashboard at https://ml.developer.apple.com/. Immediately after I go into the site, I get a message that reads "Your request is invalid.".
I click "+" to add a model collection, I enter a collection ID, a description and a single model ID and then tap on "Create". I get a message that reads "One of the fields was invalid.".
I have tried changing the IDs and the description, but there is no way to make it work.
I have been trying this for hours. Could you please guide me on how to make it work?

I am trying to set the description of an image. The metadata tag necessary to add the description is of type alternateText.
I create the child tag with the new description value:
let childTag = CGImageMetadataTagCreate(identifier.section.namespace, identifier.section.prefix, "[x-default]" as CFString, .string, value as CFTypeRef)
I then set the description tag like this:
let parentTag = CGImageMetadataTagCreate(identifier.section.namespace, identifier.section.prefix, identifier.tagKey, .alternateText, [childTag] as CFTypeRef)
let result = CGImageMetadataSetTagWithPath(metadata, nil, identifier.tagKey, parentTag)
However, when I write the image file, I get a runtime error message and the operation fails:
XMP Error: AltText array items must have an xml:lang qualifier
So, I create the qualifier tag like this:
let qualifierTag = CGImageMetadataTagCreate("http://www.w3.org/XML/1998/namespace" as CFString, "xml" as CFString, "lang" as CFString, .string, "x-default" as CFTypeRef)
But I have not found a way to associate this qualifier tag to the child tag with the description value.
What is the way to do it?
I want to find out which AVCaptureDevice.Format are compatible with what AVVideoCodecType, so to enable or disable possible configurations in the app's UI. As of today, for example, 1080p @ 240 is not compatible with h264, nor is 4K@60. But, I know this because Apple's Camera configuration explains it so in the options to choose between "High Efficiency" and "Most Compatible".What is the sanctioned way to determine if a certain video format can be used with a certain codec?. The way I am thinking about is a bit convoluted. To find the video codecs compatible with a video format I need to: - Create and configure a AVCaptureSession - Add a AVCaptureVideoDataOutput to the video session - Set the AVCaptureDeviceInput's device active format. - Query the AVCaptureVideoDataOutput availableVideoCodecTypesForAssetWriter to obtain the supported codecs (h264, hevc, ...).On the iPhone 11, the wide angle alone camera supports 17 420f video formats. Do I need to loop through all of them in order to obtain the supported codecs (set active format, query for each) or is there a better way?Thanks!

Until beta 5, creating a NSDiffableDataSourceSnapshot worked for me like this:let snapshot = NSDiffableDataSourceSnapshot<section, photo="">()In beta 6 and 7, it crashes when it reaches that point with a "Thread 1: signal SIGABRT" message.Currently Section and Photo are defined like so:enum Section {
case main
}
struct Photo: Hashable {
let identifier : String
static func == (lhs: Photo, rhs: Photo) -> Bool {
return lhs.identifier == rhs.identifier
}
}Any hints on how to resolve this?

I would like to know what is the sanctioned way to create the equivalent to a UISplitViewController on iPad using Swift UI to create what Xcode names "master-detail" apps.Thank you.
