For nearby device discovery, one device must broadcast a pairing code and the other device must scan for pairing codes.
Because there is no way to negotiate beforehand, the default is for all devices to both broadcast and scan.
This property lets you customize this behavior, restricting your app to either broadcast or scan. For example, consider a mobile app that communicates with a set-top box. If the set-top box is programmed to broadcast a pairing code, the mobile app could be set to scan only, to improve latency.
The default is kGNSDiscoveryModeDefault.

See discoveryMode for more details about device discovery.
The default is kGNSDiscoveryMediumsDefault.

Try to use the discovery strategy when the app is in the background.
Note that not all strategies will be permitted to run in the background. You can request this here, and depending on other settings and circumstances, the strategy might be allowed to continue in the background. Currently only BLE scans/broadcasts are supported.
The default is NO.
