Maps can be displayed on the simulator, but not on the real machine

[雪原高1027]

There is a strange problem, the same code, running the project in the emulator will display the map properly, but running the project on the phone will not display the map and the APP will get stuck.As shown in the uploaded picture, the first one is from the simulator and the second one is from the phone.And, view log display"ArcGIS Runtime Error Occurred.nw_endpoint_handler_set_adaptive_read_handler [C26.1.1 13.225.174.99:443 ready channel-flow (satisfied (Path is satisfied)， viable, interface: en0, ipv4, dns)] unregister notification for read_timeout failed"，What should I do with it？

Hi @雪原高1027 
you can try to run the project on another machine that has compatible machine requirements. By the way, your uploaded picture is not uploaded.
