I know chrome now supports the HTML5 filesystem api on desktop and I believe on Android but I have not seen any reference to chrome on ios supporting it. Does anyone know if it does?
No. Since iOS doesn't have an open/public filesystem.
Chrome on iOS uses Mobile WebKit, which does not support FileSystem or FileWriter APIs. You can test it out by pointing a device or simulator to this test page.
You can learn about the client-side storage and caching options that are available on this section of the Apple Developer website.

I am trying to interact with a BLE device through webBle. I was able to do this in Chrome in Android. I was trying to do that same thing in iOS Chrome as well using.
navigator.bluetooth
But it was not working and after some research, I found that it's supported only in macOS and not in iOS.
I was wondering if there is any way for me to interact with the BLE device on iOS using a browser?
Web Bluetooth is not supported by Mobile Safari or WkWebView and has not been added by major 3rd-party browsers on iOS. There is however a Web Bluetooth-specific browser called WebBLE which includes an implementation of Web Bluetooth. It is open source software with code available on GitHub.
I've developed a web app that needs to work on mobile devices offline. I've looked into progressive web apps and I'm pretty excited by the trend. Sadly, Apple still doesn't have working support, but it looks like that's changing https://cloudfour.com/thinks/apple-starts-work-on-progressive-web-apps/
Even though Apple devices don't support PWAs as Android does, it seems like certain features are already supported such as offline storage via IndexedDB(?). Does anyone know if I can currently use IndexedDB via PouchDB (for instance) to save/retrieve data? A link to a web app with this capability would be very helpful.
All I need to do for my app to function is to be able to open pdf's located on the local file system and update/retrieve data from a browser based db. Hopefully this is possible.
I don't know what a progressive web app is, yet you can definitly use PouchDB on apple devices.
The pouch docs (dating back to 2015) still say that there's no support for IndexedDB on iOS Safari as the implementation is too buggy. Back then you could use PouchDB via WebSQL on iOS.
Recent versions of iOS and Safari do support IndexedDB, see the caniuse on IndexedDB. So you should also be able to use PouchDB via IndexedDB.
Preface: there are questions (some good, some bad) already in existance on StackOverflow about webRTC support on various browsers and platforms, including iOS. However I couldn't find anything definitive that was more recent than ~2012, and this is a rapidly-changing field.
I'm working on a browser-based webapp that uses webRTC for minimal-latency peer-to-peer data transfer (not for audio/video, unlike most applications it would seem - all I need is DataChannel).
I hit a snag when I started testing the data-transfer part of the project and discovered that iOS devices still don't natively support this in their built-in browsers (despite some recent rumors).
Bowser is a free open-source browser App for iOS that purports to support webRTC on iOS. The problem is that when I try to open the app, it simply crashes and closes. I've tested this on an iPhone 5 and 5s. Googling has failed to turn up alternatives - even Chrome for iOS doesn't currently support webRTC it seems.
My questions:
1) Are there alternative browsers (even iOS-version restricted) that are currently supporting webRTC, or is there anything promising coming down the pipeline?
2) Does Bowser actually work (webRTC) on iOS devices where it doesn't crash immediately upon launch?
3) What strategies have other people used to work around this limitation?
As of iOS 11, WebRTC is now supported in Safari: https://developer.apple.com/library/archive/releasenotes/General/WhatsNewInSafari/Articles/Safari_11_0.html#//apple_ref/doc/uid/TP40014305-CH13-SW1
Check out crosswalk project ( https://crosswalk-project.org )
This Provides runtime of Chromium engine for native support in older devices.
1) Are there alternative browsers (even iOS-version restricted) that are currently supporting webRTC, or is there anything promising coming down the pipeline?
Answer:
There is a Browser called Bowser that supports webRTC.
2) Does Bowser actually work (webRTC) on iOS devices where it doesn't crash immediately upon launch?
Answer:
It's not crashing as of now.But I couldn't successfully test with anything so far.I have raised an issue about it
3) What strategies have other people used to work around this limitation?
Answer:
Apple is yet to support WebRTC in Webkit so as of now the only way would be develop a native or Hybrid app that would support the unsupported WebRTC APIs.
You can develop a hybrid app powered by OpenWebRTC or cordova-plugin-iosrtc
Which is the WebView of a PhoneGap app, is the Safari mobile or desktop one?
Is it possible to use WebGL in PhoneGap apps? If not which they work around to use them being able to submit the app to the Apple Store and Android Store
Will I be able to submit to Apple Store a PhoneGap app that uses WebGL?
UPDATE:
iOS 8 brought WebGL support on the UIWebView and WKWebView, so if you don't want to support previous versions you can use it without CocoonJS
See more details on ludei's website
OLD:
If you want to create HTML5 apps with WebGL for iOS and android, try CocoonJS
Right now it's the only way to create WebGL apps that run on iOS and android
I just figured out your issues in two points.They are-
phonegap build app links won't open in safari. For More details Please check HERE
Neither the iOS nor Android browsers support WebGL so it is pretty much a non-starter in PhoneGap.
Apple are clearly working towards supporting WebGL in a more general sense, as can be seen in their support for it in iAds.
It’s possible to take advantage of WebGL using standard embedded web views ( using private APIs).
check HERE too fro browser support.
I personally recommend Ejecta for it being open source:
https://github.com/phoboslab/Ejecta
The Android port doesn't seem widely active, but the main ios port seems well maintained, supporting WebGl.
The latest Android versions support webGL directly - if using older Android versions, Crosswalk can also be used along with phonegap to utilize webgl support.

I'm currently working on ipad IOS Safari. Thinking of adding some plugins to the application. but found some article saying that IOS Safari doesn't support plugins. Any expert know how true is the statement? Thanks
Safari, like all iOS apps, does not support plug-ins or any other form of customization. Your only option is to create an app with a UIWebView. Quite a few browser apps can be found in the App Store.
iOS 9 update: Safari still does not support plug-ins; however, it is now possible to build an app that blocks specific content via a JSON file. Content blocking rules only affect the Safari app and the new SFSafariViewController (UIWebView and WKWebView instances are unaffected).
The fact that you need to jailbreak it to use them actually proves that Apple is not supporting the use of plugins.
As of iOS 9, browser plugins are supported (as content blockers).
It DOES support plug-ins, you have to be Jailbroken to add any though. Install iFile from cydia then in iFile go to /System/Library/Internet Plug-Ins
The QuickTime Plugin is in there already, which proves that plugins are supported
And you can customize apps if your jailbroken
