By specifying a path with `BAZEL_APPLE_LAUNCH_INFO_PATH`, `bazel run` of an application will write the following newline-separated information to that file: * The string `device` if running on a device, otherwise the lldb platform (e.g. `ios-simulator`). * The UDUD of the device. * The PID of the launched application. This information can be used to attach `lldb` to the running application. Since `devicectl` waits until the process exists before writing to `--json_output`, you’ll need to use `BAZEL_DEVICECTL_LAUNCH_FLAGS` to not use `--console`.

Maybe the format of the file should be json, to allow us to add more to it in the future? Edit: Yeah, going to do that. |
