Apple was forced by EU to be more forthcoming about warranty policies.
Apple provided warranty, as a MANUFACTURER, is limited to 1 year and Apple pushed it warranty extension for 2 to 3 years (2 years for iOS devices, 3 years for Macs). It covers a range of issues that can appear after the sell.
EU wasn't really happy with this because EU law mandates a 2 years warranty by the SELLER, for issue existing before the sell. EU thought that Apple was forcing clients to get a warranty extension even if they were entitled to a 2 year coverage (similar but not exactly identical).
Now Apple clearly states this distinction.
So if you bought your Apple product in another shop, after 1 year, you need to get in contact with that shop, that will contact Apple to identify the issue and see if this is linked to a preexisting problem or link to your usage. In the later case, your "seller provided" warranty won't help you.
