Is it possible that I bypass tableView.makeView so that I can create a NSTableCellView on the fly (based on some logics)? func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? { if NSTableColumn.identifier.rawValue == "labelColumn" { let myCellView = NSTableCellView() myCellView.textField.strinValue = "label text" return myCellView } else { let complexView = loadFromNib() // of NSTableCellView // populate complexView return complexView } }

My macOS application utilizing NEDNSProxyProvider. i have a requirement to intercept only DNS requests of a certain query type, while others are expected to continue to their respective origin. For TCP there are two kinds of extensions NEAppProxyProvider and NETransparentProxyProvider. The latter is capable of returning NO from handleNewFlow causing the flow to proceed to communicate directly with the flow’s ultimate destination, instead of closing the flow. Is there a way to configure NEDNSProxyProvider to work in transparent mode for letting the flow to proceed to communicate directly? Current NEDNSProxyProvider limitation of dropping the connection when NO is returned requies me to open new socket and proxy the requests which causes noticable performance degradation under load.

I have an older project with a mixed ObjC + Swift codebase. I'm in the process of converting everything to Swift in the hopes that Xcode will work better again when the Codebase is not mixed anymore. This is an example of the issues I'm currently facing: The class IVMapViewController is defined in ObjC and the property mapViewModel is declared in the ObjC Header fine. The ObjC Header file is included in the bridging header. I'm trying to access the property mapViewModel in an swift extension on the same class. I can actually compile & run the code just fine, but Xcode Autocompletion does not work, and Xcode generates "Phantom" errors in the Issue Navigator (those errors also stay there when a build completes successful) On the other hand, if I put an actual error in the code, compilation fails, but the actual error will NOT show up in the Issue Navigator. I'll have to dig through the build log to find the actual error. Am I doing anything wrong? Do I need to adjust some project setting?

In objective-c, I created a category, like @interface NSArray <__covariant ObjectType> (ppEx) @end Look at this ObjectType, I wrote a method like - (NSArray *)pp_map:(id(^)(ObjectType element))block;which act like the map function in Swift. you can call it like NSArray <NSString *>*values = @[@"1", @"2", @"3", @"4"]; NSArray *valueMap = [values pp_map:^id _Nonnull(NSString * _Nonnull element) { return [NSString stringWithFormat:@"Hello %@", element]; }]; Now I need to add a property like mapBlock, I want to realize the same func; @property (nonatomic, copy) NSArray *(^mapBlock)(id(^paramBlock)(ObjectType element)); I did it. But when I call this method in Xcode, it can't complete automatically. values.mapBlock(^id _Nonnull(ObjectType _Nonnull element) { }) It's unable to recognize type NSString, and always show ObjectType which can cause error. I can manually change it to NSString, but it's too complicated. I think it's a problem of Xcode. Can anybody help me?

Hello. I have three questions about the Sensitive Content Analysis (SCA) framework: SCA seems to be asynchronous. Is there a limit to how much a single app can send through it at a time? For video analysis, can the video be broken into smaller chunks, and then all chunks be hit concurrently? Can a video stream be sampled as it's being streamed? e.g. Maybe it samples one frame every 3 seconds and scans those? Thanks.

I have some Swift classes in my project that extend an Objective-C base class, which in turn extends NSObject. I did this years ago when Swift was new in order to take advantage of some Objective-C code that was difficult to rewrite in Swift. It's not a common situation but it has been working fine for a long time. One of these classes is used as the key to a Dictionary and thus needs to be Hashable. The way I did this was to implement an == function and override the 'hash' property. It is a very simple case where the identity of the object is based on a single integer: static func == (lhs: FishModel, rhs: FishModel) -> Bool { return lhs.fishId == rhs.fishId } override var hash: Int { return fishId } I believe that I initially tried to add "Hashable" to the class definition but was told it was redundant. I'm not sure why that is, but it worked fine without it. Today I took the latest Xcode update to 15.2, and now my project won't compile anymore. The compiler error says that my class "does not conform to protocol Hashable". Adding Hashable to the class definition did not fix it. There are also some unusual errors about missing files, such as abi.json, swiftdoc, swiftmodule, and swiftsourceinfo. Was this caused by the Xcode update? How do I fix it?

My application requires me to clear all the notifications from the notification centre after a certain time duration. I have tried using a combination of removeAllDeliveredNotifications & removeAllPendingNotificationRequests and they work fine up until OS 17. So then I tried using removeDeliveredNotificationsWithIdentifiers & removePendingNotificationRequestsWithIdentifiers to check if it works consistently for all OS, but they hasn't worked either. Is there any other way to clear the notifications consistently for all OS?

I have this Objective-C code that works well if placed inside viewDidAppear method - rotates view into the Portrait orientation; UIWindowScene *windowScene = self.view.window.windowScene; if (!windowScene) { return; } UIWindowSceneGeometryPreferences *preferences = [[UIWindowSceneGeometryPreferencesIOS alloc] initWithInterfaceOrientations:UIInterfaceOrientationMaskPortrait]; [windowScene requestGeometryUpdateWithPreferences:preferences errorHandler:^(NSError * _Nonnull error) { // Handle error here }]; Now I need to do that same rotation after user pressed Read button but before the selected document is loaded in another view. The problem - I can't figure out how to force view update after the code is executed. I see initial view rotated only after exiting that selected document, but I need it rotated before entering it. Thank you

The entered value in the text view of pdf is getting disappeared after clicking on the submit. We are not manipulating the entered value anywhere. This was working fine until 17.1 update. Please let me know if there is any solution for this issue.

I need to instantly and without rotation animation change the screen orientation (and accordingly the size of the frame self.view in the UIViewController). If I do it like this in UIViewController: - (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id&lt;UIViewControllerTransitionCoordinator&gt;)coordinator { [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator]; [CATransaction begin]; [CATransaction setDisableActions:YES]; [coordinator animateAlongsideTransition:^(id&lt;UIViewControllerTransitionCoordinatorContext&gt; context) { [self.view setFrame:CGRectMake(0, 0, size.width, size.height)]; } completion:^(id&lt;UIViewControllerTransitionCoordinatorContext&gt; context) { [CATransaction commit]; }]; } Then, at the moment the screen orientation changes to, I see a flickering of view. How can I do what is necessary?

I am working on the project in which we are migrating from iOS project to framework. I am facing issue with Objective-C and swift interoperability. I have one Swift class let suppose profile, it has been exposed to objective c import Foundation @objc public class Profile: NSObject { @objc public var name : String? @objc public func getName() -> String{ return "XYZ" } } When I am importing “ProductName-Swift.h” it is showing me error in generated header for the module map like “@import ModuleMapPrivate not found” I wanted to know is there any way in which I can import “Profile-Swift.h” instead of “ProductName-Swift.h” ?
