[BUG] handle account switching when accounts have the same id

[angristan]

Is there an existing issue for this?

• I have searched the issues (both open and closed)

Current Behavior

This is basically like elk-zone/elk#1510.

In the following example, I have 3 accounts:

Handle	Local ID
angristan@mstdn.io	1
angristan@kpop.social	1
admin@mstdn.io	5363

-> The ID can't be used to identify an account by itself, we need the instance as well.

I think this could be fixed here:

mastodon-ios/Mastodon/Scene/Account/AccountListViewModel.swift

Line 130 in 65bf555

let isActive = activeAuthentication.userID == authentication.userID

By switching to:

let isActive = activeAuthentication.userID == authentication.userID && activeAuthentication.domain == authentication.domain

or something like that. I wasn't able to setup Xcode to be able to run the app locally, so I can't test 😬

Expected Behavior

The account switcher should show ✔ only for the current account

Steps To Reproduce

Connect with accounts on different instances that have the same local ID

Environment

- Device: iPhone 14 Pro
- OS: iOS 18
- Version: v2024.12
- Build:6891

Anything else?

Ah, looks like identifer could work as well
