I have used SceneKit for several years but recently have a problem where a scene with fewer than 50 nodes is partially drawn, i.e., some nodes are, some aren't, and greater than 50 nodes are always draw correctly. This seems to have happened since concurrency was introduced. (w.r.t. concurrency, I had been using DispatchQueue successfully before then.) Since all nodes (few or many) are constructed and implemented by the same functions etc. I'm baffled. When I print the node hierarchy all nodes are present whether few or many. SceneView() has [.rendersContinually] option selected. Every node created (few or many) has .opacity = 1.0, .isHidden = false I haven't tried setting-back the compiler version as that is not a long term solution, and I know the same code worked fine then.

I didn't find a suggestion box on Swift's website so I'll post it here. SwiftCharts are great but limited. I need more data on a single chart. Candlestick and OHLC type charts would be an excellent addition. Hopefully, influencers from Apple can make that happen. Thanks.

by selecting Help under my Help menu item or cmd-h no window appears until the menu bar is touched. myApp.swift file: import SwiftUI import QuickLook @main struct myApp: App { @Environment(\.openWindow) var openWindow @State var helpURL: URL? = nil var body: some Scene { WindowGroup { ContentView() } .commandsReplaced { CommandGroup(before: .appInfo) { Button("Quit") { NSApp.terminate(nil) }.keyboardShortcut("q") } CommandGroup(before: .help) { //FIXME: only shows help if the menu bar is touched again. Button("Help") { helpURL = Bundle.main.url(forResource: "help", withExtension: "txt") } .keyboardShortcut("h") .quickLookPreview($helpURL) } } } } How should this be coded for proper action? Thanks

running my Xcode app in Simulator: screenshots are sent to Library/Developer/CoreSimulator/Devices followed by the cryptic code for the device ( given in /Library/Developer/CoreSimulator/Devices/device_set.plist ), a subdirectory then the PNG file. This is very inconvenient. How to I set the desired directory?

How do I access a returned value from a Process(), in this case 'which'... var sips_path : String? //MARK: locate sips on local machine let which_sips = Process() which_sips.executableURL = URL(fileURLWithPath: "which") which_sips.arguments = ["sips"] do { sips_path = try which_sips.run() } catch let error as NSError { sips_path = "/usr/bin/sips"; print("Failed to execute which_sips", error) }line 8. gets compiler error "Cannot assign value of type '()' to type 'String?'" I believe, but cannot prove, 'which' returns a string. .run() throws and throws are for errors only, right? So where is the result of calling which?It seems I should use a closure to use $0 but it's already in one...line 9. intends to assign a default path.

I have developed an app using SceneKit since Swift came out. Now SwiftUI is out and uses structs rather than classes. SceneKit is a cascade of classes. As a newbie, I am concerned that my code might be obsolete through depreciations soon after publication and I'd rather get ahead of the issues now. So, is SceneKit long-term viable? My first attempts at converting my custom classes to structs seems impossible without Apple leading the way. If I understand correctly, I can make a struct whose only member is an instance of a class, but the benefits of the struct, e.g., minimal memory, processing time, etc., are lost.

Prior to Sonoma 14.0 and Xcode 15.0.1 my custom class was encoded in a consistent pattern that I exploited to append the file many thousands of times. Now, the encodings are of a seemingly random pattern that cannot be exploited to append. This may be a result of efforts to make the encoding more efficient or virtually any other reason. My questions are: how do I revert to the previous JSONEncoder while using current OS & Xcode versions?, i.e, what files and in what locations do I restore? is it likely to be sustainable if I did so? It has been previously noted that atomic files are not "append able" which is why I used JSON in the first place. Any info or suggestion is appreciated. Thank you.

My app complied when “Minimum Deployments” was 12.x but with 13.3 I get the alert: " 'dsyev_' was deprecated in macOS 13.3: The CLAPACK interface is deprecated. Please compile with -DACCELERATE_NEW_LAPACK to access the new lapack headers." Where do I enter this compiler flag? I am using XCode 14.3 Ventura 13.3.1 on an Intel macMini Build Phases:Link Binary With Libraries (3 items) libf77lapack.tbd libclapack.tbd liblapack.tbd each of which is provided by Apple. I have rooted around in “Build Settings”, “ Build Phases”, and “Build Rules” but can’t see where to put the compiler flag. Thanks
