It would be really useful if we could import a GPX file and simulate a custom route. Alternatively, add a sea route as one of the available trip simulations (under Features > Location), with the device starting from a port and ending at the same or different port.
I am aware that a custom route can be manually added through Xcode, but I cannot run my application via VS Code and still use the custom route I created. Having the feature available directly through the iOS simulator, similar to how Android emulators can add a custom route, would be especially convenient.
