首先，我有一个 SwiftUI 视图，其中包含一个列表和 Horizo​​ntalView 中的文本。稍后我将使用 ForEach() 但现在我只是用一个文本来保持简单。

import SwiftUI

struct ContentView: View {
    var body: some View {
        List{

                        print("Device-1 Connected.")
                    }

            }.navigationBarTitle("BLE Devices")
            .onAppear(perform: connectBLEDevice)
    }

    private func connectBLEDevice(){
        let ble = BLEConnection()
        // Start …
