conath / Data+Hex.swift
Last active September 19, 2024 12:17
A close to complete CoreData Bluetooth peripheral implementation of the Bluetooth HID Keyboard standard. As of iOS 14, the services are blocked by the system so it's impossible to make an iOS device act as a bluetooth keyboard, for example.
import Foundation
extension Data {
init?(hexString: String) {
let len = hexString.count / 2
var data = Data(capacity: len)
for i in 0..<len {
let j = hexString.index(hexString.startIndex, offsetBy: i*2)
let k = hexString.index(j, offsetBy: 2)
let bytes = hexString[j..<k]

Shakes a UIView left and right, a good duration seems to be 0.15s

self.transform = CGAffineTransform.identity.translatedBy(x: 8, y: 0)
