Popover view won't close keyboard
I have a popover view containing a tableview, and inside of the tableview are various UITextFields. If one of the text fields is selected and the keyboard is showing, and I swipe downwards on the popover view, the popover closes, but the keyboard remains visible. I updated my viewWillDisappear method on the view controller to have it issue a resignFirstResponder to the active input view when the popover closes, and although this code gets called, it doesn't close the keyboard. The problem only exists on an iPhone. When I run the same code on an iPad, it works as expected (tapping outside of the popover view closes both the view and the keyboard). If I dismiss the popover myself after issuing resignFirstResponder, that works. It is only the case where the user swipes down to dismiss that the problem appears.

How accurate is BGTaskScheduler?
When I submit a request for a background refresh through BGTaskScheduler, how likely is it that iOS will execute the task at the time I request? I know that with the pre-iOS 13 way of doing this, iOS didn't really guarantee any particular schedule or frequency except that it it would try to execute the task when it wasn't busy. I don't see any language in BGTaskScheduler that talks about this. The only clue is that the field specifying the time is called "earliestBeginDate" which suggests that iOS might execute it later than that date. If I submit a BGProcessingTaskRequest instead of a BGAppRefreshTaskRequest, does this change the behavior? I'd like to know this so that I can tell my users what to expect. Thanks, Frank

Using Xcode with arbitrary Git repository
My company uses Git repositories hosted with a service called Beanstalk. These are standard Git repositories that I can work with in the terminal window using the 'git' command line interface, which works fine and remembers my credentials. I'd like to use Xcode's integrated version control support, but it has never worked correctly with my repositories. In some cases, it works but prompts me to enter my credentials each time I try to do something. In other cases, it fails with a message that says "failed to start SSH session: Unable to exchange encryption keys". The account settings on Xcode only let you set up accounts with specific hosted Git services (Github, Gitlab, Bitbucket). It's nice that Xcode recognizes these specific Git providers, but how do I set up a repository that is hosted elsewhere? Thanks.

Continuous autofocus not working on iPhone 14?
I have an app, which has been in production for about 8 years, which uses a live camera view for the purpose of capturing barcodes. The app configures the camera for continuous autofocus with this code: if ([videoDevice isFocusModeSupported:AVCaptureFocusModeContinuousAutoFocus]) {             videoDevice.focusMode = AVCaptureFocusModeContinuousAutoFocus; } This has worked fine for years, but a customer who just upgraded to an iPhone 14 says that it doesn't work on his phone; the image never focuses and the barcode cannot be read. Has something changed recently, either in iOS or with the iPhone 14, that would render this code incorrect? Xcode does not flag it with any warnings. Thanks, Frank

What happened to Info.plist and AppDelegate?
I don't really like to use Storyboards (I prefer individual XIB files) and I definitely don't want to use SwiftUI or "Scene Delegates". I'm familiar with the steps necessary to create my own UIWindow in AppDelegate. With each subsequent version of Xcode, it seems to get harder and harder to set up a new project the way I prefer. In order to get rid of the default storyboard, I have to both delete the file and then remove the word "Main" from Main Interface in the target, which is not obvious (you sort of have to backspace over it and hit Enter). With the addition of "Scene Delegates" (I don't know what they are and I don't care), I now have to remove some methods from AppDelegate and a key from Info.plist. With the current version of Xcode, I'm left with an app that has no other values in Info.plist and no methods in AppDelegate except didFinishLaunchingWithOptions. What happened to all that stuff? Should I manually create it or copy it from an older project? Will iOS even still call the rest of the AppDelegate methods if I create them? What happens if I want to change something that used to reside in Info.plist, such as Bundle display name? Do I just go in and add it? Why can't Apple just add a third option to create an empty project instead of making you start with Storyboards or SwiftUI? I know that Apple is keen on attracting new developers who have time to learn whatever they put out, but I hope they still care about people like me, an iOS developer since 2009 who doesn't want to completely relearn iOS programming every three years. Thanks, Frank

Minimum functionality for private distribution?
I have a customer who wants to give his employees an iPad that does nothing other than display some fixed videos and PDF files. The customer has an Apple Business Manager account an an MDM. The solution we discussed is that my company would build their content into a simple app, distribute it to them via private distribution in the app store, and they would use their MDM to put it on their iPads in Single App Mode. My concern is that Apple will still need to review the app and may reject it on the grounds that it violates the "Minimum Functionality" rule (4.2). Is this rule enforced even for B2B apps that are destined for private distribution? Thanks, Frank
