The MacStudio has only one account on it, and that is of course an admin account. The password to this account is lost. The MacStudio has an association with my AppleID I log into developer.apple.com with. To recover, this procedure was followed: The recovery mode was entered by holding down the power key for 15 seconds. In the options that appeared the "Forgot all passwords" option was clicked on. I entered the same credentials I log into developer.apple.com with. The credentials were accepted. The shell was launched, and the in the shell the command "resetpasswords" entered. The message: "If you don't know the password for any user on your Mac, you can deactivate your Mac and set new passwords for all users. An internet connection will be required to reactivate your Mac". Beneath this message there was in blue text: "Deactivate Mac". I did not proceed after this because I was not sure what deactivation would mean for the files on the computer. On it there is code written in Swift that needs to be preserved. If the deactivation is done will the files be preserved, and be accessible? Or does a deactivation remove all files?

In the example code in this thread: https://stackoverflow.com/questions/61235935/understanding-some-nwbrowser-i-managed-to-get-working there is this line: print("result ", result ) The second argument in the print statement, the "result" variable, is not a String type. It is instead a struct whose definition begins in line 10731 in the "Network" import file. Somehow the print function knows how to convert this into a string for printing to the terminal. I conclude, with some uncertainty, that the instructions for doing this conversion have to be defined in this struct. Where in this struct is the conversion defined? If not defined there, how is the conversion done?

The need is to take pictures with Swift code settable parameters such as F-Stop, exposure time, and zoom level, in an iPhone 14 Pro. What AVCam methods control these? If there are none, are there other ways to do this? The option to have the torch constantly light on, or off, is also needed. Flash will not be used.

The need is to persist between launches the state of storyboard objects such as of type UISwitch, UITextField, etc. Can this be done using @AppStorage? If so how can @AppStorage be set to watch these? I tried getting @AppStorage to watch an outlet class member variable that is connected to the storyboard object: @IBOutlet weak var iPhoneName: UITextField! @AppStorage("iPhoneName") var iPhoneName: String = "" This got an error because the variable to be watched is already declared. I decided to make the the watched variable different than the one connected to the Storyboard's UITextField object: @AppStorage("iPhoneName") var striPhoneName: String = "" and got the error: Unknown attribute 'AppStorage' . In what import library is @AppStorage defined? If @AppStorage cannot be used for this, what is the easiest way to code storyboard object persistence? I am looking for an easy, and quick way. I am not concerned with memory usage right now.

I added a scene to an existing story board that already has other scenes. I put focus on the new scene, and in the Identity Inspector's "Class" field I gave it a class name. The "Storyboard ID" field did not show in this inspector. Why would it not? No file named after the class name I gave it appeared in the "Project navigator". Is this supposed to happen automatically? Or must I create this Swift file that contains the class definition for the scene manually?

I have a UITextField object in a storyboard's scene where the user is make numeric entries. Because this field is for numbers only I set the keyboard type to "Number Pad" in attributes. But this keyboard does not have a return key which leaves the user unable to signal when the entry is complete, the keyboard should be put away, and the entered value processed. I tried all the other numeric keyboards also, and found that none of them has a return key. The default keyboard does, but it is a full alphanumeric keyboard which is undesirable for that field. How can I cause the return key, done key, or whichever does that function, appear on a numeric only keyboard?

The function: browseResultsChangedHandler: ((_ newResults: Set<NWBrowser.Result>, _ changes: Set<NWBrowser.Result.Change>) -> Void)? returns two Set type parameters. There is data in each element of these sets I need to display in a view. What is the best way to convert these sets to an array that can be iterated in a "ForEach" statement so they can be displayed in a View? When I attempt to do it on a set directly I get the error: Cannot convert value of type 'Set<NWBrowser.Result>' to expected argument type 'Range<Int>'

On the 4th question of: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/NetServices/Articles/faq.html I see: "you can ask the Bonjour to reconfirm the record" I am basing my code on the TicTacToe example at: https://developer.apple.com/videos/play/wwdc2022/110339/ I believe the DNS records which remains after the device that put them there shuts down is causing problems for me when again. Using the DeviceDiscoveryUI as in that TicTacToe example how are these records "reconfirmed" ?

In TicTacToe example there is in the override method "PasscodeViewController.viewDidLoad()" this snippet of code: if let browseResult = browseResult, case let NWEndpoint.service(name: name, type: _, domain: _, interface: _) = browseResult.endpoint { title = "Join \(name)" } What confuses me: The use of the "case" keyword without a switch statement. The "case" keyword does not have a constant to compare with to decide if will branch here. And what of the method call to NWEndpoint.service() being set equal to something? Is this actually defining what the service method will do when the system calls it?
