Hi,
I am working on a similar concept to when the Activity Ring resets at midnight, but I was wondering wha tis the best approach to take? Detecting the date change is not the issue. The tricky part that I see is that the device will probably be locked nor can I count on the app being in the background.
I was looking at a few options that I do not believe will meet my needs:
1) A Silent Push Notification - The problem is that delivery is not certain by any means according to WWDC sessions / docs.
2) State Change - I can detect date change when user the user opens the app, is there a way to emulate the resetting the rings without the user having to launch the app?
3) Background Refresh - Now this is where I could be wrong, but from what I understand this is based on usage patterns fo the app only. So, I am not certain that I can count on this as well.
So, I ask, any suggestions?
Thanks.

Hello All,
I have a Widget that is date based (updates at midnight) that works in the Simulator, but for some reason does not work on an actual device.
I checked online and the suggestion that I found was to ensure that the OS version is the same, which they are, but still it's not working.
Here's how I am testing on Simulator:
1) Set date time to 11:58.
2) Allow the system clock to roll over to midnight.
3) The widget updates - expected behavior.
On Device:
1) Set screen auto lock to never.
2) Charge the phone.
3) Clock rolls to midnight, the Widget does not update.
Which also brings me to my second question, is there a way to detect a Widget update when the phone is locked?
Thank you

Hi,
Is it possible to dynamically update a Widget / show a View based on a specific time?
For example, something like the following:
func getTimeline(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
var entries: [SimpleEntry] = []
// Generate a timeline consisting of five entries an hour apart, starting from the current date.
let currentDate = Date()
// Get specific date / time to update then compare it to system's curren time.
var components = DateComponents()
components.hour = 12
components.month = 0
let midnight = Calendar.current.date(from: components)
if midnight == currentDate {
let entry = SimpleEntry(date: Date(), text: "", configuration: ConfigurationIntent())
entries.append(entry)
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
} else {
for hourOffset in 0 ..< 6 {
let entryDate = Calendar.current.date(byAdding: .hour, value: hourOffset, to: currentDate)!
let entry = SimpleEntry(date: entryDate, text: update, configuration: ConfigurationIntent())
entries.append(entry)
}
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
}
}
Thanks,
Hi,
I have an UICollecitonView that loads a placeholder image within a ColletionView cell without any problems. The placeholder image is loaded via ‘Assets’ using a string property.
class SampleImageView: UIImageView {
let placeholderImage = UIImage(named: "Sample")
override init(frame: CGRect) {
super.init(frame: frame)
configure()
}
''''
func setImage(holder: UIImage) {
image = holder
}
private func configure() {
layer.cornerRadius = 10
clipsToBounds = true
image = placeholderImage
translatesAutoresizingMaskIntoConstraints = false
}
}
In addition, I would like to replace the placeholder image with the one taking via the camera. I know that the image from the camera is loading without any any problems.
private func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
picker.dismiss(animated: true)
guard let image = info[.editedImage] as? UIImage else {
print("No image found")
return
}
imageTaken = true
placeHolderImage.contentMode = .center
placeHolderImage.image = resizeImage(image: image, targetSize: CGSize(width: 44, height: 44))
}
And then from my CollectionView VC:
extension SampleCollectionVC: SampleMoveDataDelegate {
func didTapAdd(data: SampleData) {
// Verify that the VC is getting the image passed to it.
let photoSize = data.sampleImage?.size.width
print(photoSize)		// Append data then retake
		
if LoadData.shared.getPerscriptionData().isEmpty {
LoadData.shared.update(perscription: medicaiton)
configureViewController()
configureCollectionView()
configureDataSource()
updateData()
DispatchQueue.main.async {
self.collectionView.reloadData()
}
}
The collecitonView loads fine, but the placeholder image is displayed and not the camera image. Also fYI, I am applying the datasource snapshot on the main thread. And finally, here's the data struct:
struct SampleData: Hashable {
var sampleName: String // Perscription name
var sampleImage: UIImage?
}
Does anyone have any recommendations to handle this situation?
Thanks,
I am able to statically load data and have it display in a CollectionView Diffable / Snapshot view without any problems. But I am getting the following crash ‘Thread 1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value’ when attempting to update the data from modal viewController.I am using a shared instance pass data between the viewControllers, and I can use a print statement to see that the data is getting appended. I also tried to update the data on the main queue, but I still got the same error.Here’s the code that I am using, and would appreciate any help.func update(data: [Data]) {var snapshot = NSDiffableDataSourceSnapshot<Section, Data>() snapshot.appendSections([.main]) snapshot.appendItems(data) self.dataSource.apply(snapshot, animatingDifferences: true, completion: nil) }Thanks,

With iOS 13, I am having where the an UIImage is not being properlty displayed on the screen - I am getting a black blob. I ried setting the tintColor with no luck. I am not using Storyboards and only trying to use images - not text & images. Any suggestions for a workaround / solution?Thank you,Paul

I see that there are a bunch of threads related to this issue with older XCode 11 builds, but I just started seeing the isuse with Mac Catalina Beta 8. I am actually seeing the issue with XCode 10 on Catalina. So probably safe to say that it's Mac OS related. I believe that Is anyone else seeing this issue?-Paul
