+
+```bash
+xcrun simctl list
+```
+
+Example of emulators listed :
+

+    iPhone 15 (128F95FC-F499-4B09-A3B2-55937BF52B0B) (Shutdown)
+    iPhone 15 Plus (86591FC6-B3E7-43A2-9E9B-D4A2A90DAF31) (Shutdown)

+```
+
+Then you can start the device you want with :
+
+```bash
+xcrun simctl boot <UUID>
+```
+
+For example, to start `iPhone 15 Pro`, you should run :
+
+```bash
+xcrun simctl boot 9D38F87D-273B-4D8F-8AD5-E901C1974C1E
+```
+
+!!! warning

+
+    ```bash
+    open -a Simulator
+    ```
+
+!!! note
+    To shutdown the simulator, run :
+
+    ```bash
+    xcrun simctl shutdown <UUID>
+    ```
