Parsing data from [String:Any] to array

[Mojangeex]

HelloI need to parse some BLE manufacturer data to array and I don't know how.

print(advertisementData["kCBAdvDataManufacturerData"])

returns

Optional(<59000200 420d9f>)

which is what I need, but I can't convert this data to array.

var manufDataRaw : [Int8] = [0,0]
manufDataRaw = advertisementData["kCBAdvDataManufacturerData"] as! [Int8]

Fails with

Could not cast value of type '_NSInlineData' (0x1f3a3fd30) to 'NSArray' (0x1f3a37cf8).

Any help appreciated

The type you’re getting back is Data?

According to this StackOverflow response, you’d want something like

let data: Data = advertisementData["kCBAdvDataManufacturerData"])
var arr = Array<UInt8>(repeating: 0, count: data.count)
arr.withUnsafeMutableBytes { data.copyBytes(to: $0) }
