I am seeing the following log in the console in Xcode Version 15.0.1 (15A507): Cannot use inflection engine (Checking that the token is the correct type): I am able to reproduce the issue using Apple's own sample code, "Building a Localized Food-Ordering App" associated with WWDC21 Session 10109: What's New In Foundation, simply by building and running the sample code. That log message immediately appears a few times in the console when running that sample project. I'm assuming given it is happening in Apple's own sample project, that this is merely console noise and basically something out of my control.

My App development language is only Arabic. I am using textField to Login User, whenever user long pressed, ToolTip showed up. Problem is with tool tip text it is flipped. My device language is English

let formatter = DateIntervalFormatter() formatter.dateStyle = .none formatter.timeStyle = .none formatter.dateTemplate = "EEEjm" Produces, in my locale and on my device with 24 hour time on: "Tue, 6:39 – 7:10 pm" I was expecting: "Tue, 18:39 – 19:10" Other date formatters are showing 24 hour time using the j symbol. For example: let formatter = DateFormatter() formatter.dateStyle = .none formatter.timeStyle = .none formatter.setLocalizedDateFormatFromTemplate("EEEjm") Produces, for the start and end dates: Tue 18:39 Tue 19:10 Further, NSDateIntervalFormatter.h suggests I should be able to use symbols like j. So why can't I create strings in 24 hour time with DateIntervalFormatter? Thanks for your time. iOS 16.7.1 / Xcode 15

I have built an iOS keyboard extension, before it is installed the system prefered language is "English" like so: After installing the keyboard extension the system language is set to "Corsican", like so: Corsican is being set because the bundle identifiers start with co. which maps to the ISO 639-1 language code for Corsican co. I've verified that my PrimaryLanguage is en-US, see below a section of Info.Plist. I've verified the bundle ID is the root cause by changing the bundle ID to something not starting with co and this behaviour disappears. ... <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>IsASCIICapable</key> <false/> <key>PrefersRightToLeft</key> <false/> <key>PrimaryLanguage</key> <string>en-US</string> <key>RequestsOpenAccess</key> <false/> </dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.keyboard-service</string> <key>NSExtensionPrincipalClass</key> <string>$(PRODUCT_MODULE_NAME).KeyboardViewController</string> </dict> ... This seems like a bug in iOS. Any suggestions what to try?

I am working on an app that pulls data from weatherKit, including the conditionCode property, the content of which is displayed to the user. I wish to localize the data pulled from weatherKit but when pulling data from: weatherkit.apple.com/api/v1/weather/de/{latitude}/{longitude} The conditionCode and other strings is in english. Same is true if the language parameter is set to es, ja or something else. Am I doing something wrong or is localization yet to be supported in weatherKit? I can't find any documentation on this.
