iOS Simulator SDK is missing ARM64 Architecture support

--

-

How to reproduce:
1. Create a new Unity project
2. Switch to the iOS Platform
3. Change Target SDK to Simulator SDK (Edit -> Project Settings -> Player)
4. Observe that the Architecture field is limited to x86_64

Expected result: Simulator SDK Architecture can be changed to ARM64
Actual result: Simulator SDK Architecture cannot be changed to ARM64

Reproducible with: 2019.4.39f1, 2020.3.35f1, 2021.3.4f1, 2022.1.3f1, 2022.2.0a15

Reproducible on:
macOS 12.1 (Intel)

  1. Resolution Note (fix version 2022.3.54f1):

    ARM64 Simulator support added to iOS/tvOS platforms.

  2. Resolution Note (2021.3.X):

    Adding ARM64 architecture support for simulator requires a lot of changes. We are considering them too risky for Unity 2021LTS.

    Here is the workaround:
    On ARM-based macs with Xcode 14.3+ you need to enable Rosetta Destination Architecture in Xcode,
    1) go to Product / Destination / Destination Architectures
    2) select Show Rosetta Destinations | Show Both
