To begin work you should create an instance of CentralManager
. Doing it is really easy - all you need to specify is queue(main queue is used by default):
let manager = CentralManager(queue: .main)
It is also possible to create CentralManager
instance with options:
let options = [CBCentralManagerOptionRestoreIdentifierKey: "RestoreIdentifierKey"] as [String: AnyObject]
let manager = CentralManager(queue: .main, options: options)
Handling restore state:
let options = [CBCentralManagerOptionRestoreIdentifierKey: "RestoreIdentifierKey"] as [String: AnyObject]
let manager = CentralManager(queue: .main, options: options, onWillRestoreCentralManagerState: { restoredState in
let restoredPeripherals = restoredState.peripherals
let restoredScanOptions = restoredState.scanOptions
let restoredServices = restoredState.services
})
You are responsible for maintaining instance of manager object, and passing it between parts of your app.
Note: All operations are executed in queue which you have provided, so make sure to observe UI related effects in main thread when it's needed.
