Web3 HttpProvider not works on Safari (Iphone, IOS 11.4.1)

I've written a simple project which uses the Web3JS on the client-side with Infura endpoint. Everything works great on my Chrome / Firefox:

How web3 works?
**Block number: 6779330**

But when I'm trying to run the page on my Iphone's Safari - nothing happens:

How web3 works?
**Block number: 0**

Here's a simple JSfiddle for illustrating the problem. For some reason, the web3.eth.blockNumber can't be loaded from the web3 instance.

I had a look at your code and I think the issue is in the HttpProvider declaration, it should be composed on INFURA_HOST (e.g.: "https://mainnet.infura.io") + INFURA_PATH (e.g.: "/3567d988f7534c92bd2c0d42601a097a"). Removing the "v3" from the URI and running your code works.

Web3.providers.HttpProvider("https://mainnet.infura.io/v3/3567d988f7534c92bd2c0d42601a097a"));

@jpantunes thanks for your answer! But it doesn't help :/ The result is the same: if you're running this fiddle (even with changed Infura path) at desktop Chrome - it works. If you're running it on the Iphone's Safari - the web3.eth.blockNumber is equal to 0 every time.

@pavlovdog do you have Metamask installed in your desktop Chrome? This injects the web3 library into the jsfiddle and makes the code work.

I tried with Safari and could reproduce your problem and then tried in a new Chrome install (without Metamask) and had the same behaviour. Finally in Chrome with Metamask and Brave your code works fine.

@jpantunes yeah, I've it installed, but I don't think that it matters. First of all, I've tried to run the Fiddle inside the private mode (MetaMask disabled) - it works. After that, I've tried to run the Fiddle inside Opera (MetaMask not installed at all) - also works fine.

[jpantunes]

@pavlovdog, so how are you loading the web3 library into the jsfiddle page without metamask?

It's my understanding that Opera has a builtin wallet with a web3 provider (https://blogs.opera.com/mobile/2018/07/opera-launches-first-browser-with-built-in-crypto-wallet/) so that might be why it works but I haven't tried it myself. I'm at a loss why would Chrome work with the extension disabled so my apologies if I couldn't help.

This got fixed with PR #2564 and will be released this week.
