Basically as the title states. I have the picker called Ingredients and when I go into the list and click an element it should work as a button or maybe not and use the add function to append that element into the ingredients list which is a state variable which should then in turn update the list at the bottom and display its elements, but it doesnt.

I have done other projects with a similar idea of an updating list but never with a picker. Any help appreciated. Learn more. Im having trouble with dynamic lists in SwiftUI. I cant get my list to update dynamically using a picker Ask Question.

Asked 2 days ago. Active 2 days ago. Viewed 21 times. CornMan CornMan 1. New contributor. Does one ingredient show up, or none at all?

The problem may also be that the selection passed to the Picker is an array, when it should be an element. I think the gist of it is that you shouldn't be using Pickerbecause that's not the functionality you're looking for ā€” you just want how it looks correct me if I'm wrong, but that's how I'm reading your question.

Hi everyone. I'm not sure how and when this error started but I have ignored it for at least the last 3 months now. The error message of "File Picker UI Host has stopped working" pops up every time after the splash screen; it's benign but annoying. I've tried contacting the nice people at Microsoft Support but they were offering solutions that were just run-in-the-mill debug processes and resets that hasn't worked; and I'm not keen on reformatting so here I am!

Really appreciate any help I can get, cheers guys. A possible interruption of third-party application can cause this issue. We can also consider a corruption in the system files. Let's try performing a clean boot to have this checked. Make sure that you're connected to Internet when doing the troubleshooting.

Did this solve your problem? Yes No. Sorry this didn't help. Thank you for letting us know that. This time we may try performing a repair upgrade as this also overrides corrupted system files. It will also install all the updates of Windows.

I'm wondering if from the error message how and where PickerHost. If true that the file PickerHost. If the file is from Windows 10 and if that is the only problem you seem to be having an error message at start then it should be a simple matter to delete the startup item from your configuration and be on your way.

By deleting the item from startup I don't mean using msconfig to disable the item since msconfig is a troubleshooting tool and not a startup manager. For you to have a tidy system you need to delete the item from startup, not just disable it.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The code below is for a simple form with two components; a Picker to select a letter and a Text to display the selected letter. The code compiles and runs but, when a letter is selected it does not appear in the "Selected In addition, Xcode displays a spurious? This may cause bugs by forcing views inside the table view to load and perform layout without accurate information e. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it until the table view has been added to a window.

Just for the record, I'm answering my own question based on the accepted answer above and my increased knowledge as a result of that answer. In the question I was not selecting a letter from the array but the index of the letter in the array. So, based on the insight, an alternative working solution might be:.

ForEach types inside Picker should be aligned with selection type. Asperi Asperi Thanks, that worked. However, I'm still getting the runtime warning. My guess is that it is being generated because the text field is being updated even though it is not visible while the Picker is displayed.

swiftui picker not working

Triage needs to be fixed urgently, and users need to be notified uponā€¦.The picker does not seem to behave the way it should, or at least the way Paul describes it. Despite adding the NavigationView, I still see the disclosure arrow and taping on the picker does nothing I ran this snippet and I was able to click on "Number of people" and modify the value from the screen that was pushed onto the navigation stack.

I've noticed some issues with preview not working correctly in Xcode with Swift UI, or having to press the "Play" button to get interactivity. Might just be an Xcode bug, so try running it on the device. When running on my device, at first, it seemed like it still was not working. After a few more tries, it turns out I need to LONG-tap on the picker in order to make the other view appear. And on that new view, I also need to long-tap on a selection before the app returns to the main screen, and in doing so, I get the following log message :.

This may cause bugs by forcing views inside the table view to load and perform layout without accurate information e. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it until the table view has been added to a window.

When I enter an amount, I get these 2 similar messages when I tap once on the textField and summon the keyboard :. Esowes is there additional code you could provide? Or could you drop a link to the WeSplit project description if it's publicly available? And I just modified the SceneDelegate like so added the. ForEach :content: should only be used for constant data. Instead conform data to Identifiable or use ForEach :id:content: and provide an explicit id! Take a look at Paul's article here, it'll explain why you're getting that error, and how to resolve it.

With regards to your Picker not working, set a breakpoint on window. You'll notice that it's being hit, my guess is it's intercepting your tap on the Picker.

About Hacking with Swift. Hello all and Paul! Thanks for the reply Peter, When running on my device, at first, it seemed like it still was not working. And on that new view, I also need to long-tap on a selection before the app returns to the main screen, and in doing so, I get the following log message : When I enter an amount, I get these 2 similar messages when I tap once on the textField and summon the keyboard : I am trying to bind a Picker, but it's not working.

I create a BindableObject, an instance of Settings, add it to the environment using environmentObject in SceneDelegate, and address it in the View using EnvironmentObject. When I change the selected food, I see output from printbut favoriteFoodChoice stays the same. Isn't it supposed to change?? Or am I misunderstanding how binding works with Pickers? I should be embarrassed to post from memory, since I am unable to test code posting from my phonebut I think if you remove your event handler didChange for willSet, and use only didSet, you'll get your expected result.

I killed the extra didChange notification, and corrected the syntax of your Picker control to show labels in the picker control and shortend the syntax of the ForEach loop I also moved the variable init into its declaration and removed the two init calls, in essence setting the control to the first available selection.

I copied your code, and it worked. I then uncommented out the redundant didChange. However, when I restored my old Picker code:. So, I'm not quite sure what's going on with ForEach but I'm sticking with your and hackingwithswift. Error: You don't have JavaScript enabled.
