is it possible to get location suggestions aka autocompletions in textfield in Swift UI? For example I type „Par“ in Textfield and the app shows automatically a few suggestions like in the picture below. Is there a short and smart way to do it. I haven’t found anything for Swift UI yet.
Many thanks enter image description here

Hi how do you make QuickLook usable in swiftui?
You have to implement QLpreviewcontroller with Representable. How do you do this?
I have some pdfs that are local and i wanted to use Bundle to locate them and have the pdfs shared to email and text via QLPreviewController from a swiftui button push. Can you point me in the correct direction?
Say I'm writing a new View that accepts a couple of pieces of data as arguments with which it builds its contents, what's the best way of getting a log of what data is flowing into the View?
When developing in JS, I can just write console.log(arguments), is there an equivalent in SwiftUI, and if so, where do I place the log call in my View so it won't throw an error?
James's answer got me partway there - print() is indeed the equivalent of console.log(). The other bit of knowledge I needed was to right-click the play button in the preview window of XCode and turn on 'Debug Preview'.
I'm writing an application using C++ and gtkmm. I made a Gtk stack in it. Now I want to add images instead of text on stackswitcher's buttons. I assume that it's possible because something like this is made in gtk3-demo:
Unfortunatelly the example is made using UI file and I want to do it without UI designer. For now I found this answer:
But it's not very helpful to me. The answer was to use stack.child_set_property but I checked gtkmm documentation for stack and there isn't anything like this for C++. The closest match was Gtk::Stack::child_property_name with adnotation that it returns A ChildPropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes. I suppose this may be the thing i'm looking for, but due to lack of examples I have no idea how to use it.
To sum up: Is anyone able to tell me how to set an image as StackSwitcher's label?
Ok, it seems I've found an answer. I'll post it if anyone needs it in the future:
To change Stack Switcher's text label into image I just needed to do that:
stack->child_property_icon_name(ChildName) = "Icon Name";
I am looking to implement a custom Tab Bar in iOS where selected item is bigger size than the rest of the tabs and peeks out over the content similar to this screenshot.
Could someone point to a tutorial of how to accomplish this preferably in Swift?
I faced with this task several times. I found a lot of tutorials but I've never found one that gives the ability to create a center button that part of it is out of the tab bar.
At the end, I created an approach to have it done correctly. I implemented a simple example project with instructions how to do that. Please check my Custom Tabbar Center Button repo as an example.
One more benefit of it it's center button hides correctly with the tab bar when you use Hide Button Bar on Push property.
A UITabBar contains an array of UITabBarItems, which inherit from
UIBarItem. But unlike UIBarButtonItem that also inherits from
UIBarItem, there is no API to create a UITabBarItem with a customView.
So instead of trying to create a custom UITabBarItem, we’ll just
create a regular one and then put the custom UIButton on top of the
UITabBar
Not swift, but should be easily translated.

Right now I am using one webview to show data from my aplicationDatadirectory, here everything is working fine, I get content when user click next back respectively. Now what I am doing is in onload of webview I register "touchevent" and "touchmove" in webview's html like this :-
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchstart", function mytouch(){Ti.App.fireEvent("touch", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchmove", function mymove(){Ti.App.fireEvent("move", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
on the basis of this I find swipe event. I get correct html in webview(I can see images). But I am unable to get touchstart and move call. I dont know what is the problem here. I set data in webview using url here.
Now when I set data in webview using html(I used data of my html file(given below) in one var) now I am unable to see images it just shows me one black border(empty) but here my touchstart and touchmove events are firing also my swipe is also working as expected. I am checking this functionality in iPhone.
Can any one find the issue what is going wrong here? Thanks.
I think that this depends on the time when you apply
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchstart", function mytouch(){Ti.App.fireEvent("touch", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
$.webview.evalJS('document.getElementsByTagName("body")[0].addEventListener("touchmove", function mymove(){Ti.App.fireEvent("move", {X:event.touches[0].pageX,Y:event.touches[0].pageY,length:event.touches.length});}, false);');
If you use the html property data is loaded immediately and you can use the code exactly after setting html content. If you use the url (even if it is located locally, which might be difficult for android) then you need to wait a short time until the page is loaded. There is also an event listener for that (web view-event load) but i can't say if that works for local resources but i don't think so.
In this case you should apply your javascript snippet into your html resources (if they are locally) instead of manually adding it using evalJS.
Please note that there is an issue on android that you can't use local images (resources folder) in your webview when you provide the content via html property.
I made it swipe working in iOS(in android it was working).
I did not expect this thing to be a reason but I do not know logic behind it. I was accessing .xhtml files from application data directory and it was working without any issue in android but in iOS it was not.
I just change(rename in my code) .xhtml file to .html and now it is working. :)
Hope this can help someone who is looking for the same.(or just for his interest)
Thanks.
