QUESTION
I want to validate user input asynchronously. For example, to check if email already exists, and perform validation while the user typing. To decrease API calls I'd like to debounce API calls with lodash or custom debounce function and to perform validation when the user stops typing.
So far this is my form right now. The issue is that it doesn't work as intended. It looks that denounced function returns a value from the previous call, and I can't understand where is the problem.
You can see a live example here: https://codesandbox.io/s/still-wave-qwww6

This is how lodash debounce is supposed to work:
Subsequent calls to the debounced function return the result of the last func invocation.
SEE: https://lodash.com/docs/4.17.15#debounce
You could set validateOnChange
to false
and then call formik.validateForm
manually as a side effect:
QUESTION
I have a form where the user enters their address. While they can always enter it manually, I also wanted to provide them with an easy solution with auto complete so that they could just start typing their address and then tap on the correct one from the list and have it auto populate the various fields.
I started by working off of jnpdx's Swift5 solution - https://stackoverflow.com/a/67131376/11053343
However, there are two issues that I cannot seem to solve:
I need the results to be limited to the United States only (not just the continental US, but the entire United States including Alaska, Hawaii, and Puerto Rico). I am aware of how MKCoordinateRegion works with the center point and then the zoom spread, but it doesn't seem to work on the results of the address search.
The return of the results provides only a title and subtitle, where I need to actually extract all the individual address information and populate my variables (i.e. address, city, state, zip, and zip ext). If the user has an apt or suite number, they would then fill that in themselves. My thought was to create a function that would run when the button is tapped, so that the variables are assigned based off of the user's selection, but I have no idea how to extract the various information required. Apple's docs are terrible as usual and I haven't found any tutorials explaining how to do this.
This is for the latest SwiftUI and XCode (ios15+).
I created a dummy form for testing. Here's what I have:

Answered 2022-Jan-05 at 14:09Since no one has responded, I, and my friend Tolstoy, spent a lot of time figuring out the solution and I thought I would post it for anyone else who might be interested. Tolstoy wrote a version for the Mac, while I wrote the iOS version shown here.
Seeing as how Google is charging for usage of their API and Apple is not, this solution gives you address auto-complete for forms. Bear in mind it won't always be perfect because we are beholden to Apple and their maps. Likewise, you have to turn the address into coordinates, which you then turn into a placemark, which means there will be some addresses that may change when tapped from the completion list. Odds are this won't be an issue for 99.9% of users, but thought I would mention it.
At the time of this writing, I am using XCode 13.2.1 and SwiftUI for iOS 15.
I organized it with two Swift files. One to hold the class/struct (AddrStruct.swift) and the other which is the actual view in the app.
AddrStruct.swift
QUESTION
I was working on Angular 8 project when the time came to upgrade it to Angular 12. Since I come exclusively from React environments, didn't think it would be this much of a hassle until I started. It has been 2 days that I have been following Angular Upgrade guide, but keep getting the following error:

Answered 2021-Nov-22 at 08:00As misha130 suggested in the comments, there was (a single) library not aligned with the latest Ivy changes which was causing the error. I was fortunate enough to not have a lot of dependencies in the project, so I went through each one and uninstalled it until the app started without errors.

I've got code that gets JSON data from a PHP script using axios. Currently this call is triggered on input of an input field.
This is fine except the call is triggered every key press. I would like to debounce this function for maybe half a second.

I found one though and it seems like you are wanting to create a function expression.

I need a specific behavior that I can't get with the RxJS operators. The closest would be to use DebounceTime only for values entered after the first one, but I can't find a way to do it. I have also tried with ThrottleTime but it is not exactly what I am looking for, since it launches intermediate calls, and I only want one at the beginning that is instantaneous, and another at the end, nothing else.

I am listening for changes of a publisher, then fetching some data asynchronously in my pipeline and updating the view with the result. However, I am unsure how to make this testable. How can I best wait until the expectation has been met?

You could also turn this into a custom hook which takes a ref (in your case, a n element at the bottom of you page):

Answered 2021-Nov-10 at 17:07To avoid this behaviour when creating a MaterialRadioButton
programmatically you need to set a Unique Identifier @+id
for each MaterialRadioButton
so that RadioGroup
can identify each of its children during of its selection/unselection phase. For this purpose you can use the ViewCompat.generateViewId()
to generate a Unique Id programmatically.
During the creation of each MaterialRadioButton
you can use the above method like below:
