The honest answer to ios has changed at least once, which is why old threads disagree.

Short answer

Support exists where the publisher ships a native build; everything else is streaming or emulation with the trade-offs that implies.

A cut-down port is still a port, and the difference usually shows up in player counts rather than frame rates. Console certification adds weeks to every patch, which is why fixes land unevenly. Most of the disagreement you will find online is two people describing different builds.

Crossplay versus cross-progression

Store pages list supported platforms accurately; trailers do not. Some features are disabled per-platform for reasons that have nothing to do with performance. League of Legends is not shy about hiding useful information two menus deep, so some of this is simply knowing where to look. Cross-progression carries your account; crossplay only puts you in the same lobby.

Cloud streaming sidesteps the hardware question and introduces a latency one instead. There is usually a fast way and a reliable way, and it is worth knowing which one you are choosing. Handheld versions often trail the main build by a full season.

Which versions exist right now

The community wisdom on this is roughly half right, and the half that is wrong costs the most time. The developers have changed their mind about this at least once, which explains the older advice. What follows assumes you are on a current install and have not modified it.

  • Check the store page's supported-platforms box, not the trailer.
  • Assume mobile versions are a different game with the same name.
  • Expect one number in every guide to be out of date; the method is what matters.
  • Check whether the version on sale is the current-gen one.
  • Look for a cross-progression toggle in account settings before starting fresh.

How to check before you buy

There is no hidden trick here that the game is keeping from you. Do the cheap check before the expensive one — that ordering alone saves most of the frustration. The awkward part is rarely the step itself, it is knowing which step comes first. Where two approaches both work, the one with fewer moving parts is the one to keep.

It helps to understand why a step exists, because then you can adapt it when your situation is slightly different. Nothing here assumes a particular playstyle beyond wanting the thing to work. The short version is near the top on purpose; the reasoning is there if you want to know why.

Streaming as a fallback

If you are coming to this after a long break, the terminology has probably moved on. Screenshots age faster than text, which is why this describes rather than shows. Patch notes move numbers around constantly; the shape of the answer holds even when a specific value shifts.

If your result differs from what is described here, note what is different first rather than starting over. Treat anything stated without a version number as provisional. If a step reads as obvious, do it anyway — the obvious ones are the ones people skip and then wonder about.

What you lose on the smaller platforms

None of this needs a paid tool, a third-party launcher or an account on a site you have never heard of. Half the pages on this topic were written for a build that no longer exists, which is why they stop matching what you see. A single check up front replaces a lot of guessing later.

Where people go wrong

  • Treating a rare edge case as the normal behaviour and planning around it.
  • Ignoring the platform-specific note and then wondering why the steps do not line up.
  • Assuming a guide from an older season still describes the current version.

League FAQ

Will League of Legends come to the platform I own?

If it has not been announced, treat it as no. Ports get announced long before they ship, never after.

Do I need any mods or third-party tools for this?

No. Everything described here works with the base game on any supported platform.

How long does this take?

Minutes if it goes cleanly, an evening if you hit the edge case in the caveats list. Neither is unusual.

What if none of this works for me?

Then something in your setup differs from the assumption — version, region or platform. Check those three before anything else.

Work through it in the order above and ios stops being a question you have to look up again.
