Register your app as Hotspot helper. (forums.developer.apple.com/message/30657#30657)

#import <NetworkExtension/NetworkExtension.h>

for(NEHotspotNetwork *hotspotNetwork in [NEHotspotHelper supportedNetworkInterfaces]) {
    NSString *ssid = hotspotNetwork.SSID;
    NSString *bssid = hotspotNetwork.BSSID;
    BOOL secure = hotspotNetwork.secure;
    BOOL autoJoined = hotspotNetwork.autoJoined;
    double signalStrength = hotspotNetwork.signalStrength;
}

It is, but you need permission from Apple. Once Apple allows you to use the HotspotHelper framework, you'll be able to create profiles with the hotspot helper entitlements. Check this post: How to get Wifi SSID in iOS9 after CaptiveNetwork is deprecated and calls for Wifi name are already blocked
