@pipe-line I think we have an iOs 9 device at work. I will debug it tomorrow night. What modules do you have installed?

@idoodler I started with Current Weather and Weather Forecast and then only with Current Weather, but no lucky.
Thanks!

@pipe-line ok. I just gathered the iPad. Its an iPad mini running iOS 9.3.3. I hope I won’t forget it until I get home:)

Issue has been identified. I am just preparing a pull request. Hold on tight!

idoodler

Lol. This issue has already been fixed on the 8th of April 2018 by Chris Pickett. It is available on the develop branch. It eventually will be merged with the masterbranch.

@idoodler thanks! I will try develop branch this night :)

I also identified the issue. It is related to the use of Promises, a feature of ECMAScript 6, which is not supported by iOS 9.3.5. The feature is used in multiple javascript files that are built into the core of MagicMirror2. I believe it can be fixed with a polyfill.

@thobach I don‘t think its an issue with the promise itself, but rather with the arrow (=>) operator that defines the callback.

@idoodler True! It was fixed in https://github.com/MichMich/MagicMirror/commit/6bb4db38428af7ac46a6f4240ab9cfe4bf9fcbea and I can load now the default configuration on iOS 9.3.5 again.

But I can still find one use of “=>” in the develop branch: https://github.com/MichMich/MagicMirror/blob/fb0cc61e09542533affa92b1e8bd6f9a2aca6363/js/module.js#L84.

@thobach that link you posted points me to a specific commit. I can not find any use of the => operator in the browser part In remote/develop
