I have a TextField in my toolbar that I use for a search function. I want to trigger the search by hitting the "return" key in this field. But if I do it in onCommit, the search also gets triggered when the user un-focuses the field. Is there a way to respond to just the "return" key? TextField("Search", text: $searchQuery) { editing in print("onEditingChanged \(editing)") } onCommit: { // Problem: this is triggered by both // 1. Return key // 2. Losing focus     searchModel.startSearch(query: searchQuery) }

I had the following code in a program that I used to encrypt some important files. I haven't run it in a few years. It used to work, and now it seems the password is mysteriously gone from my Keychain! The return value is now errSecItemNotFound. I'm upset with myself for not backing up the key/password somewhere else. Is there anywhere this could be hiding? Did Apple move it somewhere? I know they created this "Passwords" app in recent years, but I don't see anything in there with the "account" string I used. I run the app from Xcode, so maybe it is in the "container" data somewhere? I do see keychain files under ~/Library. Maybe there is a way to look through old Time Machine backups. Ug. So stressful. Just looking for pointers on where the data might be, and why it might have disappeared. Unfortunately it was not a "guessable" password, it was a generated 256 bit key, base64 encoded. Perhaps I could crack that with brute force if I'm determined enough... public static func queryGenericPasswordAsString(account: String) throws -> String { let query: [String: Any] = [kSecClass as String: kSecClassGenericPassword, kSecMatchLimit as String: kSecMatchLimitOne, kSecAttrAccount as String: account, kSecReturnAttributes as String: true, kSecReturnData as String: true] var item: CFTypeRef? let status = SecItemCopyMatching(query as CFDictionary, &item) guard status != errSecItemNotFound else { throw KeychainError.noPassword } ... }

Hi, I want something like sandbox-exec, so I can run things that I don't trust, and restrict their ability to read or write files to only certain locations. Like most software devs I have to download and run lots of code from the internet and the danger of this really annoys me. Unfortunately sandbox-exec is marked as deprecated and the APIs in sandbox.h say "No longer supported". I notice there is some new stuff in the Apple docs about "hypervisors" and "virtualization". https://developer.apple.com/documentation/hypervisor https://developer.apple.com/documentation/virtualization Would these APIs allow me to start and control a virtual copy of my macOS, to serve like a sandbox? Are there other solutions that people use? As an example, say that I need to download and run a copy of memcached. It's a typical open source project – you unpack a source tgz, then run configure; make and get a binary. Now I want to run that without worrying that some hacker injected a piece of evil code to copy my files and send them somewhere. So I want to say "run this binary, while disallowing file reads and writes, except for directories X,Y,Z, and disallowing network connections, except for listening on port 1234."
