I’ve a easy solitaire recreation the place I wish to share a screenshot of successful arms by way of the share sheet. I seize the screenshot effective, however after I go to share (primarily testing by way of Gmail), the primary time the share sheet for Gmail pops up, the picture is just not connected. If I shut the Gmail message and take a look at once more, it masses the picture. Is there some kind of delay I must account for within the rendering course of? I’ve learn a bunch of different threads which have every had components of the identical concern I’ve, however nothing conclusive, and I’ve not been capable of repair it. ShareLink seems to be like it could be a very good choice, however I can’t appear to get it to work, because it crashes my preview each time. Right here is my snapshot (screenshot) operate:

extension WinningHandView {
func snapshot(origin: CGPoint = .zero, measurement: CGSize = .zero) -> UIImage {
    let controller = UIHostingController(rootView: self)
    let view = controller.view

    let targetSize = measurement == .zero ? controller.view.intrinsicContentSize : measurement
    view?.backgroundColor = .clear
    view?.bounds = CGRect(origin: origin, measurement: targetSize)

    let renderer = UIGraphicsImageRenderer(measurement: targetSize)

    return renderer.picture { _ in
        view?.drawHierarchy(in: controller.view.bounds, afterScreenUpdates: true)
    }
  }

}

Here is the Button I am utilizing to launch the Share sheet:

Button("Share", motion: {
                        let picture = self.snapshot()
                        //let sharingImage = Picture(uiImage: picture).renderingMode(.unique)*/
                        
                        let activityVC = UIActivityViewController(activityItems: [image], applicationActivities: nil)
                                    let _: Void? = UIApplication.shared.connectedScenes.map({ $0 as? UIWindowScene }).compactMap({ $0 }).first?.home windows.first?.rootViewController?.current(activityVC, animated: true, completion: nil)})

It looks like some kind of race situation/delay wanted; if that was the case, how would I implement that? I’ve solely been working with SwiftUi for a few weeks, so nonetheless very a lot studying the ropes.

i’ve created a small Utility that may learn in a Gross sales Examine Image from a Vendor. On this case Rewe. Loading the Knowledge and creating within the SalesCheckView is not any Drawback and the attempt catch block don’t throws an error. However once I go into the SalesCheckListView I do get an empty Swift Knowledge question for my SalesCheck. I’ve different Querys in different Views that do work however this are not looking for what I would like. Perhaps somebody sees my mistake. Thanks in andvance.

My App appears to be like like this:

I’ve been engaged on a private iOS mission for enjoyable — basically a YouTube music participant, studying how background media playback works in native iOS apps.

After seeing that Musi (a well-known music streaming app) can play YouTube audio within the background with the display off — I bought actually curious. I’ve been making an attempt to duplicate that fundamental background audio performance for YouTube embeds utilizing WKWebView. I’ve spent a loopy period of time (most likely 20 hours) making an attempt to determine this out however have achieved no success.

Right here’s what I’ve tried thus far:

-Embedding a YouTube video in a WKWebView

-Activating AVAudioSession with .playback and setting .setActive(true)

-Including the UIBackgroundModes key with audio in Data.plist

-Including the NSAppTransportSecurity key to permit arbitrary masses

–Testing on an actual machine (iPhone 14, iOS 18.1 goal)–

What occurs:

Audio performs advantageous within the foreground.

If I exit the app and go to the lock display shortly sufficient (lower than 3 seconds) after urgent play, I can resume playback briefly from the lock display — however it doesn’t mechanically proceed like in Musi and different apps prefer it.

More often than not, the audio stops when the app is backgrounded.

I get this error constantly within the logs:

Error buying assertion:

It looks like the app lacks some particular entitlements associated to WebKit media playback. I don’t have AppDelegate/SceneDelegate (utilizing SwiftUI), however can add if wanted.

I’m tremendous curious how music streaming apps utilizing youtube as a supply get round this — are they doing one thing totally different beneath the hood? A customized participant? A SafariViewController trick? Is there a selected technique to configure WKWebView to maintain taking part in within the background, or is that this a recognized limitation?

Would actually admire any perception from people who’ve explored this earlier than or understand how apps like Musi pulled it off.

Thanks prematurely!
