Я использую iBeacon для расчета расстояния между одним iPhone другим iPhone в помещении. Я использую UUID и вставляю в код. Но я не получил расстояние от одного iPhone до другого iPhone в помещении. Я пишу код, как это. Может ли любое тело помочь мне, пожалуйста. Я получил ошибку, как это: CBManagerStateUnsupported. и еще одна проблема: [CoreBluetooth] XPC connection invalid
