I am writing a SwiftUI based app, and errors can occur anywhere. I've got a function that logs the error. But it would be nice to be able to call an Alert Msg, no matter where I am, then gracefully exits the app. Sure I can right the alert into every view, but that seems ridiculously unnecessary. Am I missing something?

So I believe my machine JUST updated to Xcode 16.3 (16E140). But it definitely just installed the latest iOS simulator 18.4. However, now my preview will sometimes give me the error Failed to launch app ”Picker.app” in reasonable time. If I add a space in my code, or hit refresh on the Preview, then it will run on the second or third attempt. Sometimes in between the refreshes, the preview will crash, and then it will work again. Anyone else experiencing this? Any ideas? Thanks

I find Xcode's Debugging Variable View to be to cluttered, even when just watching "local" variables. Is there anyway to set it so that it only shows the variables I want to watch? Would make debugging so much easier.

Debugger on Xcode 16.x is super slow and it turns out it's only this way when Xcode is connected to my iPhone via WiFi. If I disable WiFI on my iPhone everything is just fine. But that's not a solution. An engineer posted this supposed solution, https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes. Forgive me but that's not a solution, especially since we used to be able to shut off "Connect via WiFI." I've seen so many posts here and everywhere else with no one stating any clear answer. Does anyone know why has this been removed? And is anyone aware of it? I've posted in the Feedback Asst. as many others have. What gives?

It just feels as if my debugger is running super slow when I step over each line. Each line is doing string comparison, splitting text into words, really nothing fancy. It appears that every time I hit F6, the Variables View (local variables) takes 4 seconds or more to refresh. But I don't know if that's the cause, or a symptom. Just curious if anyone can shed any light on this.

Been using Xcode's Download Container for a short time, and at first there were no issues. But lately, it doesn't always download all the files from my iPhone to the Mac. Sometimes cleaning the build folder works, other times not. As well, the same happens whether I am connected to my iPhone via cable, or wifi. Has anyone else had this issue?

While running Swift's SpeechRecognition capabilities I get the error below. However, the app successfully transcribes the audio file. So am not sure how worried I have to be, as well, would like to know that if when that error occurred, did that mean that the app went to the internet to transcribe that file? Yes, requiresOnDeviceRecognition is set to false. Would like to know what that error meant, and how much I need to worry about it? Received an error while accessing com.apple.speech.localspeechrecognition service: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)"

Am new enough to SwiftUI that I that are still some concepts that confuse me. Case in point: .background The code below is meant to detect when the user drags their finger over different areas, in this case three different size circles placed over each other. The code works, but I get lost trying to figure out how the logic works. .background calls a function that's a view builder, yet doesn't an actual view? Unless Color.clear is the view it's returning? I have more questions, but might as well start with .background since it comes first? I think?

Is there a Finder type app that will read through my iPhone files? I’m working on a app that records audio files to my iPhone, and it would be much easier if I could find an app where I could scroll through the files on my iPhone from my desktop as opposed to doingit on the iPhone itself.

Correct me if I'm wrong, but with the latest version of Xcode (15.x) you can no longer add files to the iPhone simulator by dragging them into the the Files app. I also tried to share the files from my Mac desktop to the simulator. But after selecting the simulator, absolutely nothing happened. So I had to do it the long way: Add a folder to the simulator with a unique name, in the Files app Get the document path, print(URL.documentsDirectory.path()) Back track into the folder structure till I find that folder cp the files to that folder Please tell me that there is a way that I haven't found on Google, or that I somehow was doing what the Apple dox suggested, but missed a step.

Before Xcode 15, when I could access the info.plist file, I was able to add exceptions to the App Transport Security Settings so I could connect with my home server, which has no HTTPS, just HTTP. But in Xcode 15 I have no idea, not can I buy a clue with google, on how to do this. Please help! Thanks p.s. I should probably add that one site mentioned going to the Target section of your project allows easy access to info.plist. Yet for some strange reason, there is no item in Targets, which is odd, as I can debug my. project.

Can I open two separate Xcode windows with the same project ? I have multiple monitors, so would love to be able use them to view different files of the same project. Is there a way?

Is it possible to switch to a new View without using NavigationStack or NavigationLink or NavigationView? I know I can do it with a Bool, which either shows the second view, or the first, and then toggles the Bool. But can't I do something like this? Which obviously doesn't work. struct BasicButton: View { var buttonLabel = "Create User" var body: some View { Button { CreateUser() //another SwiftUI view, not a function } label: { Text(buttonLabel) } } }

So like the title says, when I start up Xcode the preview won;t work till I run a debug session using the simulator. Sometimes the debug session is unable to start the simulator, which I can start manually then run a debug session. Once all the above is done, preview works. Any idea what is causing this behavior?
