2. If not, what alternatives do you usually use on iOS ?
3. For a cold wallet + watch-only setup, is there a reliable way to achieve this on iOS?
Based from your other threads, you're already using Blue Wallet, correct?
Unfortunately, it's the best alternative that you can use but as you experienced, you're limited to Text/File transaction export/import since the QR isn't compatible.
Your alternative is to switch the offline wallet to something that can output a QR code that Blue Wallet supports instead.
Sparrow Wallet is one good alternative, it can output both old and new animated QR code, Blue should be able to read it.
And it's very easy to import Electrum wallets to Sparrow.
1. Does Electrum have an official iOS release?
It's QML code suggests that it can be updated to support building for iOS.
However, it's not complete, that's even an understatement since it's not even half close to being ready.
I can't see any hint on the developers (
or at least the main QML Electrum developer) on prioritizing it as well.
