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.
