Today the Connect page asks me to confirm if I am a trader or not under DSA. I am an independent developer and have several apps in App Store. I have no idea what a trader is. The DSA defines a trader as “any natural person, or any legal person irrespective of whether privately or publicly owned, who is acting, including through any person acting in his or her name or on his or her behalf, for purposes relating to his or her trade, business, craft or profession.” If you have questions about your status as a trader, consult with your legal advisor. I emailed Connect support but their reply is very "official" which confuses me more.

I always get the following debug messages when I debug a simple test app: 2021-02-03 06:27:08.068287+0800 objcapp[4385:33065] Metal API Validation Enabled 2021-02-03 06:27:09.530861+0800 objcapp[4385:33767] Errors found!

Is there any way to get rid of these messages? They are really interfering my focus on coding and debugging.

I really need help. Can anyone decrypt the following message for me: Dear Developer, We identified one or more issues with a recent delivery for your app, "MYAPP" 2.0 (1200). Please correct the following issues, then upload again. ITMS-90288: Invalid Code Signing Entitlements - The entitlements in your app bundle signature do not match the ones that are contained in the provisioning profile. According to the provisioning profile, the bundle contains a key value that is not allowed: '' for the key 'com.apple.application-identifier' in 'MYAPP.app/Contents/Frameworks/libsqlite3s.dylib' ITMS-90286: Invalid Code Signing Entitlements - Your application bundle's signature contains code signing entitlements that are not supported on macOS. Specifically, value '' for key 'com.apple.application-identifier' in 'MYAPP.app/Contents/Frameworks/libsqlite3s.dylib' is not supported. This value should be a string starting with your TEAMID, followed by a dot '.', followed by the bundle identifier . The 2 dylibs are built by myself and for years I did not have this problem with submission. What should I do? Although I know something is wrong with entitlements/signature, but I have no clue at all on what I need to exactly.

It seem Apple is forcing developers to use new Xcode 14.3 and Ventura. I am having various rudimentary problems with Xcode 14.2. Today I created a new project and was surprised to find out that there is Info.plist in the project. I have to copy one from an older project. I am wondering if Xcode 14.3 does the same thing (not creating Info.plist). Or I am quite behind the trend because I had not updated my apps for more than a year. EDIT: Why PRODUCT_BUNDLE_IDENTIFIER is invalid?

I have had this issue for a long time. If I configure any auto layout constraints in TableViewCell, I get extremely weird layout behavior in IB designer; however, layout is completely good during runtime. For example, with a completely new project and a single NSTableView on the main view, I get: If I resize main view, the tableview won't get resized Every time I reopen the project, the tableview would shrink by height. It seems the shrinked height is doubled every time. For example, in the following screenshot, the gap is 56. Next reopen will double the gap to 112. Is this a known bug? I would want to file bug report at https://feedbackassistant.apple.com.

I have a tableview with a column which has an inner tableview. I want to change height of the outer tableview to match the height of the inner tableview. outerTableView.reloadData() let range = outerTableView.rows(in: summaryTableView.superview!.visibleRect) outerTableView.noteHeightOfRows(withIndexesChanged: IndexSet(integersIn: range.lowerBound..<range.upperBound)) The above code will cause an exception: WARNING: NSTableView detected a rowView was requested from inside of the -heightOfRow delegate method. That is not supported!

Dare anyone try the following code in any Playground: // Define a model that conforms to Codable struct User: Codable { var name: String var age: Int var email: String? } // JSON data (as a string for demonstration) let jsonString = """ { "name": "John Doe", "age": 30, "email": "john@example.com" } """ // Convert the JSON string to Data if let jsonData = jsonString.data(using: .utf8) { do { // Parse the JSON data into the User model let user = try JSONDecoder().decode(User.self, from: jsonData) print("Name: \(user.name), Age: \(user.age), Email: \(user.email ?? "N/A")") } catch { print("Error decoding JSON: \(error)") } } I tested with Xcode 16.2 and latest 16.3, it reliably crashes the lldb server!

For an initial launch of Xcode, the GatherProvisioningInputs usually takes 60 seconds for a simple project. Subsequent build is fast though. But the build process seems got stuck at VeryModule of the MyFramework target, which usually takes 15 seconds.

I want to use NSTask to run a shell script that resides in Resouces directory. The script performs some operations on files in the app's Data directory.But I am concerned that Apple could refuse my app for some reasons. Can anyone confirm if this approach is safe. Thanks.

I have the following code:@implementation NSWindow (Coordination) - (NSPoint)convertPointFromScreen:(NSPoint)point { NSRect rect = NSMakeRect(point.x, point.y, 1, 1); return [self convertRectFromScreen:rect].origin; }I get a compiliation warning:Category is implementing a method which will also be implemented by its primary classI know Swift has builtin preprocessor directives to detect SDK version, but don't know how to do this in objc. Any suggestions?

I'm not sure what I have missed in the new release, but I cannot set Standard Value in IB anymore like that I did for years. The Standard Value is disabled in constraint dropdown list. If I clear the hardcoded value, "Standard" will appear but when I press ENTER, the old value comes back. Is this a known bug or a new 'feature'?

I have a need to tell if 2 images are different by unimportant details. For example, one image is only slightly different than another because: *) It is a little stretched *) or it has 99% portion of another (only missing some pixels on borders) I wonder if there is an efficient algorithm to achieve my goal. Any suggestions are welcome.

Got confused about these 2 methods. NSObject protocol has an isEqual: method. NSObject implements NSObject protocol but it does not have isEqual:, instead it has an isEqualTo: method. What's the magic behind the design? Or is the doc wrong? Should I implement both methods in a derived class?

In IB I connect a button to a VC and set the segue kind to 'Popover'. Now I have a problem. How do I get the NSPopover and its delegate? -(void)prepareForSegue:(NSStoryboardSegue *)segue sender:(id)sender {     NSLog(@"%s: %@", __func__, segue.destinationController);     NSViewController* vc = segue.destinationController; }

I want to add "Show in Finder" in my app that is similar to the one in Xcode. How do I do this using objc?
