Hi, Can we create a dependent/independent WatchOS application and a tvOS application using Objective C ? If yes, can some sample be shared please. When I go to create these applications from XCode, in the language dropdown, only Swift is available as an option. Thanks !

I am intending to show an alert message in macOS through a C++ based application. I am using CFUserNotificationDisplayAlert for the same. Below is the piece of code that I have used to display the alert window which I have written in the .mm file: CFOptionFlags cfRes; CFUserNotificationDisplayAlert(0, kCFUserNotificationCautionAlertLevel, NULL, NULL, NULL, CFSTR("Message Header"), CFSTR("Message Body"), CFSTR("Ok"), NULL, NULL, &cfRes); The above works fine on Catalina but does not show the alert window in BigSur. Is there anything I am missing ?

There is an 'open' command in mac with some options as: -g  Do not bring the application to the foreground. -j  Launches the app hidden. While it claims to launch the application hidden and/or in the background – it always seems to behave the same way.  Is there some ‘input’ the application is supposed to receive and behave suitably (that is, not show a UI if it is opened in such a mode)?  How do I access this intent of the user? Thanks !

I am writing an application which is capable of running as a regular application – with a GUI, AND as a ‘daemon’ – servicing other GUI based applets. The user is expected to decide in which mode they want to run the application. The questions are: Can this be done? On Windows, I am able to do this by allowing user to ‘install as a service’ and I can programmatically check if the application HAS been started as a service or not – and take the appropriate code path. What is the equivalent in MacOS? On startup, how do I check if the application is being launched in regular mode, or launched as a daemon What are the system interactions which I need to specifically hook into if it is launched as a daemon.

I am building a macOS application and would like to check if the application is running in the background or not. Was referring documentation for the same and found few links under 'Archives'. Below is the document I could get: https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/DesigningDaemons.html Is there some latest documentation available on this subject ? Any pointers would be helpful. Thanks in advance.

We are building iOS and MacOS application that uses libraries built in C++. If the iOS app and MacOS application consumes the library as dynamic linking i.e. using .dylib, can the application be released through AppStore ? Is there a restriction in AppStore for using such dylib files in the application?

Hi,I am trying to create the User Interfaces for my app programatically i.e. without using the storyboards/xib's. I have been able to do the same for iOS application. However, not able to do it for WatchOS. Does WatchOS not allow creation of interfaces via code without using Storyboards?Thanks in advance !

Hi,If I have dynamic libraries like testlib.dylib, and I use it in my C++ code using dlopen(), dysym() etc, will it be allowed? This C++ code would be accessed via an Objective-C bridge from Swift. I read somewhere that if any app uses these in their code, it would be allowed to be pushlished on App Store, hence wanted to check the same.Regards,Abhishek

Hi,I have some core functioanlity which is written in C++. I would like to use this in my Swift application as a dynamic library or a static library. Can someome please guide how to achieve the same ?
