iOS Safari v12 compatibility

[ArtisArtStudio]

The wheel just doesnt draw at all on iOS (12.5.6). Both Safari and Chrome for iOS not showing wheel at all. Anybody had this as well?

Hi @ArtisArtStudio, I'm not able to reproduce.

Can you share some code (codepen)? Does it happen with one of the examples?

Notes:

• All web browsers on iOS/iPadOS use Safari under the hood.
• I've tested using the latest version of Safari on iPadOS/macOS and it works fine.
• Safari 12.5.6 came out in 2019, and this library is compiled to ES6, so it should work.

below line with "resolution:" was causing the problem:

i._mediaQueryList = window.matchMedia('(resolution: ${window.devicePixelRatio}dppx)'), i._mediaQueryList.addEventListener("change", i._handler_onDevicePixelRatioChange, { once: !0 }) }

So I put a version control and run this line only if iOS is >=13 then it worked for me. resolution is not (fully?) supported by iOS. (however it seemed to work for iOS>13 that is why I put the version control)

@ArtisArtStudio good find!

Do you know if matchMedia was throwing an error?

You could also try calling wheel.resize(), although it is already called internally when the wheel is initialised.

I see that the change event of MediaQueryList was implemented in iOS Safari 14.0 (June 2020).

Also ResizeObserver was implemented in iOS Safari 13.4 (Sep 2019).

Hi Tim,

It wasnt throwing error. I connected iphone 6 for dev tools called Inspect and it was just stopping at that line when I debug so that is how I realized. So probably I should check for iOS>14. Not sure what resize() does? it works for my purpose (I think) how would eliminating change event affect it? It seem to work for me. I have mediaqueries in my landscape.css and it resizes it properly. :)

Another point: on the same iOS, 12.5.6, with Safari, the touch (interactive) feature doesnt work. It works on Chrome on the same iOS/machine. I didnt dig down why as it doesnt matter for my case. So I write here just for information.

@ArtisArtStudio thats interesting, it will probably be difficult for me to reproduce that without a device on hand. I might ask around see if anyone has an old iPhone they aren't using :).

Open to suggestions if anyone knows!
