Action proposal: IsGrayscaleEnabled

[msubb]

Description

I think it would be valuable to be able to detect if grayscale is enabled on the device.

I tried to add it myself but was unable to figure out how to implement it.

I put this at the bottom of the enum Device {

    /**
     If grayscale is enabled on the device, Boaz code
     */
    static var isGrayscaleEnabled: Bool {
        UIAccessibility.isGrayscaleEnabled
    }
}

I also added this code to Intents Extension/Actions/

import AppIntents

struct IsGrayscaleEnabled: AppIntent, CustomIntentMigratedAppIntent {
    static let intentClassName = "IsGrayscaleOnIntent"
    static let title: LocalizedStringResource = "Is Grayscale On"
    static let description = IntentDescription(
"""
Returns whether Grayscale is on or off.
""",
categoryName: "Device"
    )
    func perform() async throws -> some IntentResult & ReturnsValue<Bool> {
        .result(
            value: Device.isGrayscaleEnabled
        )
    }
}

I'm not sure what I am doing wrong, the extension showed up in the shortcuts app but didn't seem to actually be detecting the state of grayscale.

It probably has to run in the main app, not the intents extension. I added it. Will be available in the next update.

Awesome thank you! I’m excited to use it in future shortcuts. If you don’t mind me asking do you know when the next update will be released?

[sindresorhus]

Not soon. Every update requires some users to restart their device (because of a dumb iOS bug), so I try not to release updates too often.

Gotcha, I implemented the fix you mentioned moving the code I wrote from Intents Extension/Actions/ To Shared Actions

Testing it on my Iphone 13 Mini it appears that the shortcut just always returns yes. Looking at the pictures I uploaded it looks like I had grayscale disabled in both but I guess it is just not captured by IOS screenshots.

Gray Scale ON Shortcut Logic Gray Scale OFF

The action I added works on my device (iOS 17). Try the code from the main branch instead of your changes.
