I'm having an issue with using a bluetooth barcode scanner on my iPad running iOS 11.2. The key events are not propagating in the same order as my desktop. Windows and Mac OS do not have this issue. Has this happened to anyone else or does someone know why this is happening? I've tried Chrome, Safari, and Firefox on the iPad and they all share the same output, but the Dolphin browser works fine.

3rd party browsers on iOS - like Chrome, Firefox and Dolphin - must use WKWebView or UIWebView for rendering webpages and I'm fairly certain the speed and order of events is determined by the rendering engine.
It's not surprising to me that Chrome and Firefox both behave the same as Safari, because all three use the newer WKWebView. My best guess is that Dolphin is still using UIWebView, which is why it behaves differently. If you'd like to confirm that WKWebView is to blame, see if it works in Firefox Focus which uses UIWebView.
Unfortunately, there is not much you - or the browsers - can do about it.
that's because an ipad is more slower than a Desktop you cannot compare two different architectures them. Ipad always be more slower than Desktop.

Sometimes i check browser support features on Can I Use website. Now i looked at touch events compatibility and realised that iOS Safari support this feature, but Safari doesn't. What is the difference between Safari and iOS Safari on caniuse.com? As far as i know Safari browser is tied to the iOS and is not supported on Windows/Linux, so it should point to same browser. Maybe it's divided to mobile and desktop versions? I couldn't find any answer on their website and on other sites as well.
I enclose an image as well (support may change in the future):
Safari refers to desktop Safari on a Mac, whereas iOS Safari is Safari on an iOS device.
Is it possible to use chrome://inspect to debug Chrome running on an iPhone that is plugged in via USB?
Basically I just want to use Chrome on my laptop to debug, not Safari.
No, this is not possible. The reason for that is that due to the limitations of iOS Chrome uses WebKit while on all other platforms it employs Blink to render web pages. Chrome DevTools' core which resides in Blink hence it is not available on iOS.
I am using calendar mode of Datebox with my jQuery Mobile project, everything works fine but when I use useFocus to open calendar wherever I click on the input field, it isn't stable in iPhone (or other iOS devices), sometimes it opens and many times it acts like crashing. But the same is working good in Desktop browsers, when I use without useFocus it works right in mobile devices also, I see same stability issue in plugin website demos too. How can we correct this issue?
I am developing a web app for iPad and testing it on Safari on Mac and Safari on iPad Simulator. Now there are some issues with CSS in iPad Simulator which work quite well in Safari on Mac.
Now my question is,
Is there a powerful debugging tool for Safari in iPad Simulator?
When running safari in an XCode device simulator, the desktop Safari (v6) Develop menu shows those devices. From there, you can fire up the developer tools (DOM browser etc.) for the mobile browser. This helped me debug an mobile safari css issue without hardware.
Note: As of iOS6 this is not the correct way of doing remote debugging, leaving this answer for historical reasons but you should look into remote inspection with Safari, here is a good article: http://jeffreysambells.com/2012/09/22/ios-safari-web-inspector
Have a look at this, (a bash script I wrote) https://gist.github.com/2241976. It will allow you to open the iPad simulator and run Webkit's remote inspector, which will look just like this.
iWebInspector is quite a powerful tool for the iOs simulator's Safari.
It uses the same inspector as Chrome and it works nicely (I've used it myself and found it really helpful).
From their website
iWebInspector is a free tool to debug, profile and inspect web
applications running on iOS Simulator (iPhone or iPad). You can check
resources, see and change HTML & CSS, use breakpoints on JavaScript
code, create charts and more just as if you were on Safari for
Desktop, Chrome or Firebug.
It works for any web in Safari -the web browser-, for a chrome-less
webapp (full-screen) and also for apps using UIWebView -including
PhoneGap applications-.
I need to check rendering of a large sum of HTML5 "widgets" that will be shown in an iPad WebKit. Which desktop browser gives me the most similar renering experience? My widgets mostly consist of SVGs positioned with CSS3 and some CSS masking.
Is it Safari on a Mac?
EDIT: The desktop OS is not a concern, I can pick whatever I want for this...
EDIT: What particularly interrests me is if desktop Safari is closer to iOS Safari than Chrome is. They are both based on WebKit, but I see a lot of tiny rendering differences between Chrome and iOS Safari.
How about mobile Safari on the iPad Simulator?
Unfortunately, the iPad Simulator is Mac-only. If you can't test on that, Apple recommends using Safari and changing your user agent string to the iPad's user agent string. You can find instructions from Apple here.
Try real Safari. It uses Webkit and since you're on windows, you can't download the iPad simulator.
On the desktop, anything that uses WebKit is going to give you a similar rendering experience especially with regards to more technical things like SVGs. Unfortunately, there are still browser-specific quirks that you won't be able to notice without actually testing it on either the simulator or a real device.
