in iOS 17 (21A5326A) audioSession.setCategory(.playAndRecord, mode: .default,options: .allowBluetooth) does not set input to bluetooth. In iOS 16 it does.
Here the steps to reproduce:
Create project with storyboard.
in info.plist add
NSMicrophoneUsageDescription
Your microphone will be used to record your speech when you press the "Start Recording" button.
put in ViewController:
import UIKit
import Speech
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override public func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
AVAudioSession.sharedInstance().requestRecordPermission { granted in
}
}
func startAudioSession(){
let audioSession = AVAudioSession.sharedInstance()
do {
try audioSession.setCategory(.playAndRecord, mode: .default,options: .allowBluetooth)
try audioSession.setActive(true,options: .notifyOthersOnDeactivation)
print(audioSession.currentRoute.description)
} catch {
}
}
@IBAction func btnTap(_ sender: UIButton) {
startAudioSession()
}
}
put button on the Main.storyboard and link it to btnTap
Connect bluetooth headset to iphone, start the App and tap button.
in iOS 16 see the current route - bluetooth.
in iOS 17 see the current route - speaker
