`tuist run` always fails

Troubleshooting & how to
1

Question or problem

tuist run always runs xcrun simctl boot twice. Once to install the app on the device and again before running it. The second always fails with Error: Unable to boot device in current state: Booted

Expectation

Expected behavior: Tuist should either skip the boot step before launch if the simulator is already booted, or only boot once during the entire run flow.

Context

  • Tuist version: x.y.z

Reproduction (mandatory for problems)

  1. Run tuist run -scheme <scheme_name> --device "iPhone 17"

  2. Select a simulator device when prompted

  3. Observe the error when it attempts to boot the simulator again before launching.
