I have a large dictionary of words in an app that I’d like to localize. I'm thinking of asking a human translator (or AI agent) to translate them. I might translate each word by machine and include the translation in the data I provide to the translator as candidates. How can I export this data to the translator in XLIFF format? Does iOS have API for XLIFF generation or interpretation? Are there decent open source options written in Swift?

I'm amazed by agentic coding presented in the "Translate your app using agents in Xcode" session. Does agentic translation support localized strings contained in Objective-C modules? Does it support strings in Interface Builder XIBs?

What resources can assist translating Objective-C to Swift? Perhaps best practices or patterns? Can a coding agent automate translating Objective-C to Swift?

Can developers programmatically turn on Reduce (Liquid Glass) Transparency for their app? Or just for a view? Or will iOS 27 permit setting Reduce Transparency on an app-by-app basis?

In iOS and iPadOS 26 beta 9 (and previous batas), setting the tintColor property on a navigation bar does not tint bar button items. The text and images are always black in the following cases: Buttons displaying only text (initWithTitle:) Buttons displaying only a symbol (initWithImage:) Buttons displaying system items, ie., UIBarButtonSystemItemCancel. Nav bar title The tintColor seems to be respected for: Selected-state background for buttons configured with changesSelectionAsPrimaryAction. To reproduce, Create a UINavigationController, Add bar button items to its navigation item, Set a tint color as in the following statement: self.navigationController.navigationBar.tintColor = [UIColor redColor]; Then note that the bar button items are black rather than red as expected. I have filed a feedback: FB19980265.

What is the best way to switch between Core Data Persistent Stores? My use case is that I have a multi-user app that stores thousands of data items unique to each user. To me, having Persistent Stores for each user seems like the best design to keep their data separate and private. (If anyone believes that storing the data for all users in one Persistent Store is a better design, I'd appreciate hearing from them.) Customers might switch users 5 to 10 times a day. Switching users must be fast, say a second or two at most.

I'm primarily an iOS developer. Every day that I develop, Mac Time Machine backs up a gigabyte or more of data. I'm trying to reduce that as much as possible. No data involving the simulators seems important enough to backup. If I ever need to restore Xcode, I'd reinstall rather than restore from Time Machine. But I'd want to back up code snippets, etc. What are the best practices to prevent large amounts of Xcode or simulator data from being backed up?

When I run my iOS app on a Mac using Mac Catalyst, several sharing options that show up on an iOS device in a share sheet are absent on the Mac. Clicking on Edit Extensions, I see Mail, Message and AirDrop, their switches are on and disabled. All three items show up when I share from Safari or Notes. How can I make Mail, Message and AirDrop available? For example, when sharing data, no share extensions are shown. For text, only Simulator, Shortcuts and Copy are shown.

I need to direct text-to-speech generated audio from my app simultaneously to a bluetooth speaker device AND to the internal iPad speaker. The app uses AVSpeechSynthesizer and several third party speech engines. How best to do this? I noticed the outputChannels property on AVSpeechSynthesizer...are there any examples of how to use this?

Hi. I have an iPad 7th gen running iPadOS 14.8.1. For testing purposes, I want to upgrade it to the latest release of iPadOS 17, even though the device wants me to upgrade to iPadOS 18.5. Is there a way to upgrade it to iPadOS 17? btw this would free-up a newer iPad running iPadOS 17 so I can install iPadOS 26 beta. Thank you.

Is there a way for developers to generate IPA notation from user voice input like in the Settings app (Accessibility > VoiceOver > Speech > Pronunciations)? Thought this might be a useful option for AAC apps.

Very excited about the new eye tracking in iPadOS and iOS 18. Some general eye tracking questions. Does the initial iPadOS 18 beta include eye tracking? If not, in which beta will it be included? Do developers need to do anything to their app for users to control their app using eye tracking? Will all standard UIKit and SwiftUI views and controls work with eye tracking without code changes? Will custom subclasses of UIControl work with eye tracking without code changes? Looking forward to testing eye tracking.

In the Settings App, when I go to Accessibility, the only item listed in the SPEECH section is Live Speech. Can I create a personal voice on an iPad? I am using an iPad 8th gen 32 GB, running iPadOS 17 beta 2 (17.0, 21A5268h)

My iPad 8th gen running IPadOS 17.0 RC does not list Personal Voice in the Accessibility settings. Is Personal Voice creation supported on iPad? If so, on which iPad models is it supported?
