I have an app that was written in UIKit. It's too large, and it would be much too time consuming at this point to convert it to SwiftUI.
I want to incorporate the new limited contacts into this app. The way it's currently written everything works fine except for showing the limited contacts in the contact picker.
I have downloaded and gone though the Apple tutorial app but I'm having trouble thinking it through into UIKit. After a couple of hours I decided I need help.
I understand I need to pull the contact IDs of the contacts that are in the limited contacts list. Not sure how to do that or how to get it to display in the picker. Any help would be greatly appreciated.

My apps are set up to store data in a SQLite database on the device. The user is also able to add images and those are also stored on the device. The database and images are stored in the apps documents folder. The database is set up with four tables, one of them containing a list of selectable items so the information in that table is constant. The other three are read/write to the user. The database also contains a field, which contains true/false as to whether the app has been purchased or not.
My thought behind was that this would make the users data private and secure.
My apps are set up using UIKit so SwiftData is not an option unless I rewrite the entire app in SwiftUI. Or is there a good way to use SwiftData in UIKit?
Is there a way to store/move this information into the cloud so that the data can be synced across multiple devices?
Or maybe set up an import/export scenario using a CSV file for the database using Dropbox?
Any help or advice would be appreciated.
Thanks in advance.
On Jan 2, 2024 I uploaded and got released 13 new apps. The problem I'm having is that only one of the new apps is showing data in analytics, the other 12 show nothing. They are all very similar apps with pretty much the same search criteria as the rest of my apps, 42 total. All of the other apps show plenty of analytic data.
I've done searches and the apps do show up in the search.
Is there a limit on the number of apps you can have?
Is there a way to have Apple look and see if I've done something wrong that's causing the problem?
Thank in advance
I'm working on some older apps, and I don't think they were ever opened in Xcode 14. I'm updating them in Xcode 15 and I'm having some problems with the Plist. It looks like I've lost the link between the Info.plist and their related Build Settings. I want to lock the iPhone orientation to portrait. This always worked in the past.
When I change the Deployment Info, iPad Orientations or iPhone Orientations using the checkboxes the updates show up in the Info Custom iOS Target Properties (info.plist). However, they are not reflected in the Info.plist Values in the build settings. Even if I update the build settings manually, I still don't have the iPhone locked in portrait orientation.
Has anybody run into this and know how to fix it?
Thanks for the help in advance.
I'm updating my apps to iOS 17 and in Xcode 14 this code worked perfectly. However, Xcode 15 decided it wasn't going to let it work anymore.
What I want to accomplish is to set the title of the button to be white and the icon to be blue. In other words, I want to control the color of both items separately.
I'd also like to know how to set the disabled color of the button using configurations.
I've tried using baseBackgroundColor and baseForegroundColor but it doesn't seem to make any difference.
In interface builder, the button is bone stock with no attributes except the title text. (system, plain, plain)
I've tried .plain(), .tinted(), .borderless() and commenting the line out but noting gives me what I need.
Any help would be greatly appreciated.
` extension UIButton
{
func settingsBtn_Attributes()
{
self.configuration = .plain()
self.configuration?.image = UIImage(systemName: K.Icons.settings, withConfiguration: UIImage.SymbolConfiguration(scale: .large))
self.configuration?.title = K.Tabbar_Names.settings
self.configuration?.attributedTitle?.foregroundColor = .white
self.configuration?.imagePlacement = .top
self.configuration?.titleAlignment = .center
self.configuration?.imagePadding = 6
self.configuration?.contentInsets = NSDirectionalEdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 0)
self.configuration?.attributedTitle?.font = .systemFont(ofSize: gMenuTextSize, weight: .regular)
}

I have a question regarding multiple in-app purchases. I want to release my app with one in-app purchase however, I want to add two more at a later release. Currently I have all three in-app purchases set up in the app, but only one is set on the prepare for submission screen under In-App Purchases and Subscriptions.
My question is, are these additional in-app purchases going to cause a problem with my initial release? Should I delete them and just add them later with the next rev?
I had an ugly glitch when I was committing one of my Xcode projects to BitBucket. I thought it was just a wifi connection issue but there's something else going on. I've tried to commit several other projects and they are all exhibiting the same problem. I have attached a screen-shot of the window that opens when doing a commit. There are files that have been changed but they do not show in the commit window. I don't see any Xcode settings that were changed. I have deleted and reinstalled Xcode and it didn't change anything. Has anybody experienced this?
When I execute a restore on my in-app purchase I'm getting a warning, however the restore is successfully executed. I think this is something new with Xcode 14.3. My test device is running iOS 16.4
This is the warning:
<SKPaymentQueue: 0x283708a80>: No observers found that respond to "paymentQueue:shouldAddStorePayment:forProduct:", will not check for purchase intents
It fires at this point in the code. If I comment out the first line, I don't get the warning however, the restore doesn't execute. Is anybody else seeing this or do I have something wrong in my code? I know it's only a warning but any help would be appreciated.

I my app I have four steppers and each has a related field. I have the stepValue of each stepper set to 0.1. The associated fields are editable, and I have them set to have a trailing 0 when editing ends.
Everything works fine. The stepper increments at 0.1 and populates the field. When the field edited ends it has a trailing 0. The problem is that the stepper does not have a trailing zero on the whole number.
So, with the stepper, I get 0.8, 0.9, and then 1 with no training 0, hen 1.1.
How can I make sure I have a trailing 0 with the whole numbers?

In a collection view I want that when a cell is tapped to have the background color changed to indicate highlighting. When that same cell is tapped again, turn the highlighting off. When another cell is tapped, un-highlight the previously highlighted cell and highlight the new one.
I pretty much have that working but it's all done manually in code. If there's a better way using delegate methods or something, please enlighten me.
The collection view is in a pop-up view. My problem is that when the pop-up view is closed and then reopened, the last selected cell is still highlighted.
I tried this, but no-joy.
choose_CollectionView_Outlet.indexPathsForSelectedItems?.forEach { choose_CollectionView_Outlet.deselectItem(at: $0, animated: false) }
I think it's because I am manually setting the background color to indicate highlight. If anybody has a solution for this, please share it.

I'm trying to control what happens when the view background is tapped.
The view has a field, a button and a list collectionView.
When the user enters a name into the field, the button is enabled and when the button is tapped the name from the field is saved into a list collectionView.
What I want to happen:
If the field isFirstResponder when the viewBackGround is tapped then I want the superView_Tapped() to be triggered.
If the collectionView is tapped it works fine.
If the view background is tapped it works fine.
When the view backGround is tapped the field text is cleared and sone other things take place. See superView_Tapped() below.
What actually happens:
The problem I'm having is that tapping the button also triggers the superView_Tapped().
So what happens is the field is emptied and a row is inserted into the collection view with no name.
The part of the reason is that the superView_Tapped() is fired first and then the button code fires after.
Is there a way to exclude the button tap from triggering the superView_Tapped()?
let tap = UITapGestureRecognizer(target: self, action: #selector(self.superView_Tapped))
tap.numberOfTapsRequired = 1
tap.delegate = self
tap.cancelsTouchesInView = false
self.view.addGestureRecognizer(tap)
@objc func superView_Tapped()
{
if insertFld.isFirstResponder
{
insertFld.resignFirstResponder()
insertFld.text = ""
insertButton.isEnabled = false
// print("They emptied the fld when editing", gItemID)
gItemID = 0
insertButton.filled_Red_Back(title: K.Titles.add_Btn)
theOriginal_Text = ""
}
}
@IBAction func insertButton_Tapped(_ sender: UIButton)
{
if current_Item_ID != 0
{
update()
} else {
insertRow()
}
}
func update()
{
let theItemName = insertFld.text
do {
try dbQueue_GRDB.write { db in
try db.execute(sql: "UPDATE " + theTable + " SET Item_Name = :item_Name WHERE ItemID = :id",
arguments: ["item_Name": theItemName, "id": current_Item_ID])

This is regarding the keyboardFrameWillChange notification.
This code worked as expected under Xcode 14.1
With floating_Keyboard = false
Tap the textView
Full keyboard opens
textView moves up to avoid the keyboard
Change to floating keyboard
Floating keyboard opens
textView moves to home position
Tap the view background to close the keyboard
Tap the textView again
Floating keyboard opens
txtView remains at home position
Change to full keyboard
Full keyboard opens
textView moves up to avoid the keyboard
With Xcode 14.2 if the keyboard is floating and the textView is firstResponder, and the keyboard is then set back to full keyboard, the floating_Keyboard = false part of the code does not fire. This means the textView remains in the home position even though the full keyboard opens.
Is anybody else experiencing this?

I'm setting up auto layout constraints and I want the leading constraint of one of the controls on the view to be a fixed value on iPhone (CR) and equal to a % of the screen width for iPad. Can this be done in IB using the size inspector or does it need to be done programmatically? I've searched for documentation and looked at lots of videos but I was unable locate the information. If someone could provide a link to the documentation or share some sample code, I would be very grateful.
I have this code in the sceneDelegate of my app. I understand that .main is going to be deprecated. The warning says to use view?.window?.windowScene?.screen but there is no view in sceneDelegate. How can I change
let screenSize = UIScreen.main.fixedCoordinateSpace.bounds
to not use .main?
Thanks in advance.
I'm setting up keyboard avoidance to a textview.
Objectives:
Use keyboardLayoutGuide.followsUndockedKeyboard
Allow for floating keyboard on iPad
Move the textView up to clear the keyboard when it's tapped
Move the textView back when the keyboard is hidden or when the textView is not firstResponder
View layout for testing:
Three controls.
A textField
A TextView
A UIView
The constraint on the bottom of the textView is 15 pts from the top of the UIView.
This constraint is set to a Priority of 750
The code I have works fine except when the iPad is rotated.
keyboardWillHideNotification fires when the rotation occurs even though the keyboard stays undocked.
This causes the textView to drop to its home position and then pop back up again. It's very goofy looking. The textView should hug the top of the keyboard.
I tried using textViewDidEndEditing instead of keyboardWillHide but that isn't much better.
Anybody have any ideas on making the textView hug the top of the keyboard when the iPad is rotated?
