App Randomly Crashes During Continuous Sound Playback Using AVAudioPlayer

Environment→ ・Device: iPad 10th generation ・OS：**iOS18.3.2

We're using AVAudioPlayer to play a sound when a button is tapped. In our use case, this button can be tapped very frequently — roughly every 0.1 to 0.2 seconds. Each tap triggers the following function:

var audioPlayer: AVAudioPlayer?

func soundPlay(resource: String, type: String){ 
        guard let path = Bundle.main.path(forResource: resource, ofType: type) else { 
            return 
        } 
        do { 
            audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path)) 
            audioPlayer!.delegate = self 
            try audioSession.setCategory(.playback) 
        } catch { 
            return 
        } 
        self.audioPlayer!.play() 
    } 

The issue is that under high-frequency tapping (especially around 0.1–0.15s intervals), the app occasionally crashes. The crash does not occur every time, but it happens randomly — sometimes within 30 seconds, within 1 minute, or even 3 minutes of continuous tapping.

Interestingly, adding a delay of 0.2 seconds between button taps seems to prevent the crash entirely. Delays shorter than 0.2 seconds (e.g.,0.15s,0.18s) still result in occasional crashes.

My questions are:

**Is this expected behavior from AVAudioPlayer or AVAudioSession?

Could this be a known issue or a limitation in AVFoundation?

Is there any documentation or guidance on handling frequent sound playback safely?**

Any insights or recommendations on how to handle rapid, repeated audio playback more reliably would be appreciated.
