iOS17.4.1及以上,系统语言是中文,关闭系统NFC,app内调用CoreNFC弹窗显示英文（正常应该显示中文,在iOS17.4.1是正常显示中文的）

I'm trying to cast the error thrown by TranslationSession.translations(from:) as Translation.TranslationError. However, the app crashes at runtime whenever Translation.TranslationError is used in the project. Environment: iOS Version: 18.1 beta Xcode Version: 16 beta yld[14615]: Symbol not found: _$s11Translation0A5ErrorVMa Referenced from: <3426152D-A738-30C1-8F06-47D2C6A1B75B> /private/var/containers/Bundle/Application/043A25BC-E53E-4B28-B71A-C21F77C0D76D/TranslationAPI.app/TranslationAPI.debug.dylib Expected in: /System/Library/Frameworks/Translation.framework/Translation

I have a macOS application with a minimum version of macOS 12.0. I need to be able to get the current keyboard region designator. Example: The user selects a input source of English Canadian. What I want as a result of this fact is en-CA locale identifier. I get the current keyboard language with the following code func keyboardLanguage() -> String?{ let keyboard = TISCopyCurrentKeyboardInputSource().takeRetainedValue() let languagesPtr = TISGetInputSourceProperty(keyboard, kTISPropertyInputSourceLanguages)! let languages = Unmanaged<AnyObject>.fromOpaque(languagesPtr).takeUnretainedValue() as? [String] return languages?.first } This returns the language as en, but I don't see how I can get the region from Text Input Sources. I can get the input source id let keyboard = TISCopyCurrentKeyboardInputSource().takeRetainedValue() let idPtr = TISGetInputSourceProperty(keyboard, kTISPropertyInputSourceID)! let id = Unmanaged<AnyObject>.fromOpaque(idPtr).takeUnretainedValue() as? String print(String(describing: id)) This prints com.apple.keylayout.Canadian which points to the Canadian region but is not a region designator. I can possible parse this id and map it to a region designator but first I'm not sure if I will capture all of the regions and secondly what happens if the format of the id changes? If someone can point to the correct API to use it will be much appreciated.

I was wondering if there is a quick way to convert a model trained with the open source CRFSuite for use with NLTagger? It seems like retraining should be possible but was wondering if automatic conversion was supported?

i'm trying to create an NLModel within a MessageFilterExtension handler. The code works fine in the main app, but when I try to use it in the extension it fails to initialize. Just this doesn't even work and gets the error below. Single line that fails. SMS_Classifier is the class xcode generated for my model. This line works fine in the main app. let mlModel = try SMS_Classifier(configuration: MLModelConfiguration()).model Error Unable to locate Asset for contextual word embedding model for local en. MLModelAsset: load failed with error Error Domain=com.apple.CoreML Code=0 "initialization of text classifier model with model data failed" UserInfo={NSLocalizedDescription=initialization of text classifier model with model data failed} Any ideas?

Is there a way to extract the list of words recognized by the Speech framework? I'm trying to filter out words that won't appear in the transcription output, but to do that I'll need a list of words that can appear. SFSpeechLanguageModel.Configuration can be initialized with a vocabulary, but there doesn't seem to be a way to read it, and while there are ways to create custom vocabularies, I have yet to find a way to retrieve it. I added the Natural Language tag in case the framework might contribute to a solution

Does iOS provide an API for getting text predictions based on previous text? I tried with UITextChecker.completions as such let str = "Hello" let range = NSMakeRange(str.utf16.count, 0) let tc = UITextChecker() let completions = tc.completions(forPartialWordRange: range, in: str, language: "en-US") print(completions) However, this only works for completing words, not sentences. Does iOS have a way of doing this? I read somewhere that macOS does. If not, what workarounds/alternatives would you recommend?

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.

I am using NLTagger to tag lexical classes of words, but it suddenly just stopped working. I boiled my code down to the most basic version, but it's never executing the closure of the enumerateTags() function. What do I have to change or what should I try? for e in sentenceArray { let cupcake = "I like you, have a cupcake" tagger.string = cupcake tagger.enumerateTags(in: cupcake.startIndex..<cupcake.endIndex, unit: .word, scheme: .nameTypeOrLexicalClass) { tag, range in print("TAG") return true }
