QUESTION
I'm trying to implement a PHPickerViewController using SwiftUI and The Composable Architecture. (Not that I think that's particularly relevant but it might explain why some of my code is like it is).
I've been playing around with this to try and work it out. I created a little sample Project on GitHub which removes The Composable Architecture and keeps the UI super simple.
https://github.com/oliverfoggin/BrokenImagePickers/tree/main
It looks like iOS 15 is breaking on both the UIImagePickerViewController and the PHPickerViewController. (Which makes sense as they both use the same UI under the hood).
I guess the nest step is to determine if the same error occurs when using them in a UIKit app.
My codeMy code is fairly straight forward. It's pretty much just a reimplementation of the same feature that uses UIImagePickerViewController but I wanted to try with the newer APIs.
My code looks like this...
...ANSWER
Answered 2021-Sep-26 at 14:32Well.. this seems to be an iOS bug.
I have cerated a sample project here that shows the bug... https://github.com/oliverfoggin/BrokenImagePickers
And a replica project here written with UIKit that does not... https://github.com/oliverfoggin/UIKit-Image-Pickers
I tried to take a screen recording of this happening but it appears that if any screen recording is happening (whether on device or via QuickTime on the Mac) this suppresses the bug from happening.
I have filed a radar with Apple and sent them both projects to have a look at and LOTS of detail around what's happening. I'll keep this updated with any progress on that.
Hacky workaroundAfter a bit of further investigation I found that you can start with SwiftUI and then present a PHPickerViewController without this crash happening.
From SwiftUI if you present a UIViewControllerRepresentable... and then from there if you present the PHPickerViewController it will not crash.
So I came up with a (very tacky) workaround that avoids this crash.
I first create a UIViewController subclass that I use like a wrapper.

QUESTION
So I'm try to use ScrollViewReader to programmatically scroll a horizontal scroll view. I thought it would work like scrollToItem with .centeredHorizontally in UIKit, and for the most part it does, but the last few elements in the scroll view are being forcefully scrolled to the center of the screen, despite the fact that the scroll view isn't normally able to scroll that far over (without snapping back after releasing the drag, at least). This ends up creating white space across the trailing half of the screen.
I've seen some other questions about this and it seems like the general opinion is that it's not a bug? On the one hand I suppose we're telling the scroll view to center the item, and it's doing just that -- so, not a bug? On the other hand, that's not how similar functionality worked in UIKit. Also, this behavior is only happening on the trailing end of the scroll view! If it was the intended behavior I would expect that scrolling to the first element in the scroll view using .center anchor would force it into the center of the screen and leave leading white space, but this doesn't happen.
Is there an elegant solution to this? Or do we have to calculate the width of our elements + spacing and figure out based on the screen width whether we should anchor .center or just scroll to the last element with anchor .trailing in order to replicate the UIKit behavior?
...ANSWER
Answered 2021-Jul-25 at 06:31I found a package (Amzd/ScrollViewProxy) that was made before ScrollViewReader was released that functions much the same as ScrollViewReader, but also seems to not have the bug (if it is a bug) detailed in the question.
Usage examples can be seen on the repository page, but here's a quick minimal example.

QUESTION
I have been stumped by this for a few days now and can't find a solution. I have a UIImageView with a transparent background. It is on top of another view (in the example just a UIView with blue background color). For some reason, it will blend a color even if it has an alpha value of 0 (in this case full red no alpha values come out pink). The desired output is that it will show clear just like black with no alpha value.
If over white it behaves as intended (it is clear and shows white through). I have tried different ways of creating the CGContext and different CALayer blend modes and can't get it to not blend colors that don't have alpha values on them.
Here is some sample code to replicate the issue.

QUESTION
So, straight to the problem:
I've created a custom UIViewControllerTransitioningDelegate that I use to animate a view from one view controller, to full-screen in another view controller. Im doing this by creating UIViewControllerAnimatedTransitioning-objects that animate the presented view's frame. And it works great! Except when I try to adjust the additionalSafeAreaInsets of the view controller owning the view during dismissal...
It looks like this property is not accounted for when I'm trying to animate the dismissal of the view controller and its view. It works fine during presentation.
The gif below shows how it looks. The red box is the safe area (plus some padding) of the presented view - which I'm trying to compensate for during animation, using the additionalSafeAreaInsets property of the view controller owning the view.
As the gif shows, the safe area is properly adjusted during presentation but not during dismissal.
So, what I want is: use additionalSafeAreaInsets to diminish the effect of the safe area during animation, by setting additionalSafeAreaInsets to the "inverted" values of the safe area. So that the effective safe area starts at 0 and "animates" to the expected value during presentation, and starts at expected value and "animates" to 0 during dismissal. (I'm quoting "animates", since its actually the view's frame that is animated. But UIKit/Auto Layout use these properties when calculating the frames)
Any thoughts on how to battle this issue is great welcome!
The code for the custom UIViewControllerTransitioningDelegate is provided below.
...ANSWER
Answered 2021-Dec-19 at 18:12After some debugging I managed to find a workaround to this problem.
In short, it looks like the safe area is not updated after UIViewController.viewWillDisappear is called, and hence any changes to .additionalSafeAreaInsets is ignored (since these insets modifies the safe area of the view controller's view).
My current workaround is somewhat hacky, but it gets the job done. Since UIViewControllerTransitioningDelegate.animationController(forDismissed...) is called right before UIViewController.viewWillDisappear and UIViewControllerAnimatedTransitioning.animateTransition(using transitionContext...), I start the dismiss animation already in that method. That way the layout calculations for the animation get correct, and the correct safe area is set.
Below is the code for my custom UIViewControllerTransitioningDelegate with the workaround. Note: I've removed the use of .additionalSafeAreaInsets since its not necessary at all! And I've no idea why I thought I needed it in the first place...

QUESTION
I have had a document browser app up since iOS 11 (using UIKit/UIDocumentBrowserViewController). The app (let's call it "MyApp") used to create a "MyApp" folder in iCloud Drive (and/or on the device, depending on the choice made in Settings), where documents would be saved automatically.
After updating my device to iOS 15 and recompiling, without any changes to the code, the app seems not to recognize its own folder in iCloud Drive anymore. Every time a file is opened/imported from outside the app (Files, Mail, etc.), the app creates a new "MyApp" folder in iCloud Drive and saves the document there. The existing folder is renamed "MyApp 2" (and then "MyApp 3", "MyApp 4" etc. if I try to import another document).
This seems to happen only in iCloud Drive. If I choose in Settings to save documents on my device, all documents are automatically imported into the "My App" folder, as it was the case in iOS 14 and earlier.
I also tried to create a test app from scratch using the Xcode 13 UIKit document-based app template, and the behavior seems to be exactly the same... so it looks like a bug in UIDocumentBrowserViewController was introduced with the iOS update.
Did anyone notice the same? Is there a solution/workaround? Should a bug report be filed?
Thank you for your help.
[EDIT] If anybody is interested, this is the simplest way to reproduce the issue using the Xcode template:
- Create a new project in Xcode 13.0
- Choose iOS -> Document App
- Choose Interface: Storyboard and create the project (for simplicity let’s use “MyApp” as Product Name)
- Build and install MyApp on a device running iOS 15.0 or 15.0.1 with iCloud Drive enabled
- Leave the default setting for Document Storage (i.e. iCloud Drive) in Settings -> MyApp
- Create a text file with any content and save it with extension “exampletext” (i.e. the imported type identifier used by the app template - let’s call the file “test.exampletext”)
- Send an email to an inbox accessible from the device with test.exampletext as attachment
- Open Mail on the device, long-press on test.exampletext and share it to MyApp
- If a folder “MyApp” exists in iCloud Drive, it will be renamed to “MyApp 2”; a new “MyApp” folder will be created and test.exampletext will be saved in the new folder
- Sharing again test.exampletext from the mail to MyApp will create another “MyApp” folder and rename the previous one; an arbitrary number of “MyApp n” folders can be created in this way, each including one copy of the document
