In our application we have two usecases for a Hotkey/Shortcut identification API/method. We have some predefined shortcuts that will ship with our MacOS application. They may or may not change dynamically, based on what the user has already set as shortcuts/hotkeys, and also to avoid any important system wide shortcuts that the user may or may not have changed. We allow the user to customize the shortcuts/hotkeys in our application, so we want to show what shortcuts the user already has in use system-wide and across their OS experience. This gives rise to the need for an API that lets us know which shortcut/hotkeys are currently being used by the user and also the current system wide OS shortcuts in use. Please let me know if there are any APIs in AppKit or SwiftUI we can use for the above

We are building a Multi-Lingual Business Application -- where the user is able to enter values and data in multiple languages. One of our main use cases is, if a user is editing or adding to a text value or data that is in a different language. For example, the data they are editing could be in Japanese, and the user's current input language is set to English, then when they enter the editing mode, the input language is automatically set to Japanese by us -- programmatically. They can go back to editing English items, and the input language is changed back to English, and similarly, when they come back to edit the Japanese data or some German data, then the input language is again automatically changed to the respective language by the application -- without causing the user to manually go to the settings and change it. Is there any current way to have this behaviour in MacOS and iOS now? Please suggest what can be done to achieve the same.

I am creating 500 textfield widgets and then updating them and all their 40 properties at once. I require to update all 500 widgets with their properties at once as it is a usecase in our app, so pooling and showing only those that will be on screen won't really help in this case. I have found that for updating all these 500 textfield widgets with their 40 properties, the time taken is 80 to 100 milliseconds. However, if I update the non-string properties like .text, then it comes down to half which is 40 to 50 milliseconds. Wanted to know if there was a far more quicker or optimized way to do this? The following snippet of code shows what I am doing: @objc private func handleImmediateMode() { let startTime = CFAbsoluteTimeGetCurrent() for (index, textField) in retainedInputFields.enumerated() { updateAllProperties(for: textField, index: index) } let endTime = CFAbsoluteTimeGetCurrent() print("Immediate Mode -- (500 fields, 40 props): \( (endTime - startTime) * 1000) ms") } In the above code, I have already created the 500 textfield widget, and then in updateAllProperties () function I am passing the textfield widget to it and then updating the 40 properties that the widget has. Particularily, the following properties: textField.placeholder = "Input Field (index)" UILabel().text Seem to be adding the extra 40 - 50 milliseconds.

Hi, I wanted to know what is the best way to detect whether a part of string has an unavailable character, '□' (tofu box or last resort character). So far it seems to be that we will have to parse all the strings and individually check for each character and whether or not it is a part of the Unicode Scalar. And since we are a business application that deals with a lot of data as strings, this will be rather performance heavy. So wanted to know if there were any other better or more efficient ways to go about this?
