I have an 'Independent watchOS' project created in Xcode. To this project, I have linked few static libraries (as xcframework). The architecture is set to 'x86_64'.
I am able to successfully build this project and deploy it on the watch simulator. The code inside the static libraries also get called and things work fine.
However, when I try to build the same project from command-line, it doesnt work and fails with multiple errors.
Command used :
xcodebuild -target "TWWatchOSTemplateProj WatchKit App" -configuration Debug -destination 'platform=watchOS Simulator,arch=x86_64' build
Error :
/Users/abhishek.mohata/TW_Test_Projects/TWKshetrapalNative/TWLibs/TWBrahmaClient.xcframework:1:1: error: While building for watchOS, no library for this platform was found in '/Users/abhishek.mohata/TW_Test_Projects/TWKshetrapalNative/TWLibs/TWBrahmaClient.xcframework'. (in target 'TWWatchOSTemplateProj WatchKit Extension' from project 'TWWatchOSTemplateProj') warning: None of the architectures in ARCHS (x86_64) are valid. Consider setting ARCHS to $(ARCHS_STANDARD) or updating it to include at least one value from VALID_ARCHS (arm64_32, armv7k). (in target 'TWWatchOSTemplateProj WatchKit Extension' from project 'TWWatchOSTemplateProj') error: No profiles for 'com.tally.TWWatchOSTemplateProj.watchkitapp' were found: Xcode couldn't find any iOS App Development provisioning profiles matching 'com.tally.TWWatchOSTemplateProj.watchkitapp'. Automatic signing is disabled and unable to generate a profile. To enable automatic signing, pass -allowProvisioningUpdates to xcodebuild. (in target 'TWWatchOSTemplateProj WatchKit App' from project 'TWWatchOSTemplateProj') warning: ONLY_ACTIVE_ARCH=YES requested with multiple ARCHS and no active architecture could be computed; building for all applicable architectures (in target 'TWWatchOSTemplateProj WatchKit App' from project 'TWWatchOSTemplateProj') ** BUILD FAILED **
When built from command-line, why is the error related to architecture comes while the same works from xcode ?
Also, is there anything to be added to the command for signing as the details are already present in the xcodeproj.

I am building my application for macOS using CMake. My application can either be MACOSX_BUNDLE i.e. generated as a .app through CMake or it can even be a Unix-style executable. Is there a programmatic way in Obj-C to check if the executable is Unix-Style or NSBundle?

We are building an application that would be cross-platform and hence using CMake as the build system. While am able to build for iOS, macOS, tvOS etc, have not been able to build for watchOS using CMake. Right now, am looking for an independent watchOS app. Can someone help with any pointers or reference link for the same ?

I understand that if i am building a watchOS app using SwiftUI, there is no storyboard file involved. Hence, the user interface can be created all programatically. Similarly, can watchOS with Objective C be created without StoryBoards ?

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 currently on macOS Monterey 12.2 and have started an iPhone 12 iOS 15.0 simulator.
On this simulator, if I drop files from desktop or a folder inside desktop, I get an error saying, 'The file could not be opened because you don't have the permission to view it'. However, if this files is moved to some folder inside ~/Builds/SampleFiles/*, the drag and drop copies the files to the simulator. Is something specific needed to be done to provide such an access to the simulator ?
I can see that Simulator has 'Full Disk Access' under 'Security and Privacy'.

Hi,
We are developing a Business Management application for Accounting/Inventory/Invoicing etc. which is capable of being integrated with a reasonably wide variety of 3rd Party document formats – like spreadsheets, and PDF, and ALSO capable of being customized by the end-user to support additional formats. While the ‘out-of-the-box’ integrations(extensions) can be listed in the info.plist for people to opt to open a particular document type
using our application, if they wish to – what do we need to do to allow them to associate their own customized integrations.
For defining the same in plist file, we do this for already defined extensions :
<dict>
<key>CFBundleTypeName</key>
<string>TWDB</string>
<key>CFBundleTypeRole</key>
<string>Viewer</string>
<key>LSHandlerRank</key>
<string>Owner</string>
<key>LSItemContentTypes</key>
<array>
<string>com.tw.twdb</string>
</array>
</dict>

Hi,
I would like to be able to tell at any time which mission control workspace the user is currently using programmatically on macOS or programmatically check the number of desktops/workspaces are currently created on a macOS screen. I could not find any working answer during my search. Any workspace identifier works for me (uuid, workspace number...). Is there a programmatic way of doing this in Objective C ?
Thank you for the help!

I have an application that is built as an app bundle. I open a new terminal window, and launch the application through ./.
When I do this, the application UI is launched and some application logs are printed on the terminal. If I want to detach my application process from the terminal, how can the same be achieved such that I can close the terminal and my application keeps running.
Basically, how do we ‘detach’ from the parent console
once we have detected that we WERE started from the parent console ?

Hi, I am trying to use the open command from the Terminal window to open my application.
I have tried the following :
open --hide MyApp.app
open --background MyApp.app
The documentation says : --help launch the app hidden and --background does not bring the application to the foreground.
I would like to understand the difference between the two ?
What I have observed is, in both cases the application launches and my GUI Window is not in the foreground.
Am I missing something ?

Hi,
I have a shared Mac system running on BigSur 11.4 - which I access from office and home. I have a single user id, and do not want the two sessions to interfere with each other. Can I have 2 independent sessions on this Mac machine for the same user ? Basically, I am seeking guidance on ‘what kind of options/settings/helper applications' will allow me to do this.
Thanks in advance.

Hi,
We are creating a macOS application that is built as a 'Bundle' and NOT as a Unix-style application. In a specific flow, we need to attach this process to a terminal session by creating one. Now, on this attached terminal, stdin/stdout etc would happen.
We are using Objective C.
Any pointers on how to go about this would be helpful.

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 !
