log:
didRange [CLBeacon (uuid:D4C3CCC0-29FB-11E5-884F-0002A5D5C51B, major:0, minor:9, proximity:0 +/- -1.00m, rssi:0, timestamp:2024-02-15 06:48:57 +0000)] didRange [CLBeacon (uuid:D4C3CCC0-29FB-11E5-884F-0002A5D5C51B, major:0, minor:9, proximity:0 +/- -1.00m, rssi:0, timestamp:2024-02-15 06:48:58 +0000)] didRange [CLBeacon (uuid:D4C3CCC0-29FB-11E5-884F-0002A5D5C51B, major:0, minor:9, proximity:0 +/- -1.00m, rssi:0, timestamp:2024-02-15 06:48:59 +0000)] didRange [CLBeacon (uuid:D4C3CCC0-29FB-11E5-884F-0002A5D5C51B, major:0, minor:9, proximity:0 +/- -1.00m, rssi:0, timestamp:2024-02-15 06:49:00 +0000)]
