I'm trying to implement WidgetKit on my watchOS 9.1 app. When I'm editing the watch face, I see the widget looking as I would expect it to be. However, when I then go to the Home Screen, the data is redacted.
What's causing that to happen? I don't do anything luminance or security related in the widget's view:
struct AccessoryRectangularView: View {
let tide: Tide
var body: some View {
HStack {
VStack(alignment: .leading) {
Text("Height: \(tide.heightString())")
.font(.headline)
.widgetAccentable()
Text("As of: \(tide.date, style: .time)")
.font(.caption)
}
tide.image()
}
}
}
Selecting any option will automatically load the page

In Apple's documentation it says this:"This method, though convenient, is inefficient if used multiple times in succession. Achieve better performance by chaining filters without asking for the outputs of individual filters."That confuses me though because I don't know how to link them together without getting the output. For example, this is my method to apply a TiltShift filter, based on the instructions from Apple's docs. When I perform the gradient filter, I have to take the outputImage of that to pass into the next filter. What's the right way to be doing this? override public var outputImage: CIImage? {
guard let inputImage = inputImage else {
return nil
}
let clamped = inputImage.clampedToExtent()
let blurredImage = clamped.applyingGaussianBlur(sigma: inputRadius)
var gradientParameters = [
"inputPoint0": CIVector(x: 0, y: 0.75 * inputImage.extent.height),
"inputColor0": CIColor(red: 0, green: 1, blue: 0, alpha: 1),
"inputPoint1": CIVector(x: 0, y: 0.5 * inputImage.extent.height),
"inputColor1": CIColor(red: 0, green: 1, blue: 0, alpha: 0)
];
guard let gradientImage = ciImage(from: "CILinearGradient", parameters: gradientParameters) else {
return nil
}
gradientParameters["inputPoint0"] = CIVector(x: 0, y: 0.25 * inputImage.extent.height)
guard let backgroundGradientImage = ciImage(from: "CILinearGradient", parameters: gradientParameters) else {
return nil
}
let maskParameters = [
kCIInputImageKey: gradientImage,
kCIInputBackgroundImageKey: backgroundGradientImage
]
guard let maskImage = ciImage(from: "CIAdditionCompositing", parameters: maskParameters) else {
return nil
}
let combinedParameters = [
kCIInputImageKey: blurredImage,
kCIInputBackgroundImageKey: clamped,
kCIInputMaskImageKey: maskImage
]
return ciImage(from: "CIBlendWithMask", parameters: combinedParameters)
}
private func ciImage(from filterName: String, parameters: [String: Any]) -> CIImage? {
guard let filtered = CIFilter(name: filterName, parameters: parameters) else {
return nil
}
return filtered.outputImage
}
I'm trying to wrap my head around Combine still, and so in my class that handles web requests I've written this method:static func downloadNumbersPublisher(datesByType: [LottoType: (start: Date, end: Date)]) -> URLSession.DataTaskPublisher {
guard let url = downloadUrl(using: datesByType) else { return }
var request = URLRequest(url: url)
request.addValue("gzip", forHTTPHeaderField: "Accept-Encoding")
let session = URLSession(configuration: .ephemeral)
return session.dataTaskPublisher(for: request)
}What I'm not clear on though is what I actually return on line 2, the guard statement.
How do I get errors from the simulator when something is wrong with the pkpass file? I have a 'good' version of my pass.json that drags into the simulator without issues. I have a different version that does nothing, so clearly something is wrong with the JSON, but I can't find what.In the simulator I've done Debug -> Open System Log but when I drag in the bad pkpass file, nothing is displayed.
