Hi Guys,

Using latest version of Audio_recorder plugin and it is not working on IOS, i have target ios version(10), Any thoughts?

Xcode's output:

Not a working solution but if you want your build to build you can change

try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord, with: AVAudioSession.CategoryOptions.defaultToSpeaker)
to
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord, options: AVAudioSession.CategoryOptions.defaultToSpeaker);

Had the same issue resolved by @lucygeneric mentioned;

[DyaryRaoof]

also change this line
switch AVAudioSession.sharedInstanc.recordPermission(){
case AVAudioSession.RecordPermission.granted:
to
switch AVAudioSession.sharedInstance().recordPermission{
case AVAudioSession.RecordPermission.granted:

to resolve the other error

@DyaryRaoof any work around this issue ?

[LarrySimiyu]

I tried the solutions @DyaryRaoof and @lucygeneric wrote but now when I click the start record button my entire application just crashes...if anyone could help it would be greatly appreciated

[DyaryRaoof]

what error do you get when it crashes ? have you tried flutter run --verbose to see the error message ?

[MrudulAddipalli]

@DyaryRaoof @LarrySimiyu , Hi Dyaru , I have followed all the changes mentioned , but My app is crashing too, here the error, please let me know how can I solve this issue.

Flutter Output :
Fatal error: Unexpectedly found nil while unwrapping an Optional value: file audio_recorder/SwiftAudioRecorderPlugin.swift, line 42
Lost connection to device.

Line 42 SwiftAudioRecorderPlugin.swift -
audioRecorder = try AVAudioRecorder(url: URL(string: mPath)!, settings: settings)

Full Block Code -

do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord, options:
AVAudioSession.CategoryOptions.defaultToSpeaker);
try AVAudioSession.sharedInstance().setActive(true)

--------> audioRecorder = try AVAudioRecorder(url: URL(string: mPath)!, settings: settings)
audioRecorder.delegate = self
audioRecorder.record()
} catch {
print("fail")
result(FlutterError(code: "", message: "Failed to record", details: nil))
}

And as per the suggestions in github I have made below changes,

@DyaryRaoof

also change this line
switch AVAudioSession.sharedInstanc.recordPermission(){
case AVAudioSession.RecordPermission.granted:
to
switch AVAudioSession.sharedInstance().recordPermission{
case AVAudioSession.RecordPermission.granted:

Hi. I haven't used the plugin in a while. I am surprised they haven't yet fixed the issue.

Your error shows that "unexpectedly found nill while unwrapping optional" . It means the value that that that line depends on is null. Probably you don't get the permission to use the microphone , either haven't added the necessary line in info.plist or you need to use permission_handler package to get permission to use the mic before start recording.

Also try changing this line Line 42 SwiftAudioRecorderPlugin.swift -
audioRecorder = try AVAudioRecorder(url: URL(string: mPath)!, settings: settings)

Remove the ! After mPath)

Also look at the plugin in Xcode it will show you errors and will try to give suggestions to fox the error in the after you run the app.

Hope this helps.

Hi @DyaryRaoof , yes I have permission handler, and also Microphone is allowed in App Settings,

after changing the ! , I am getting below error for the same,

d/ios/Classes/SwiftAudioRecorderPlugin.swift:42:58: error: value of optional type
'URL?' must be unwrapped to a value of type 'URL'
audioRecorder = try AVAudioRecorder(url: URL(string: mPath), settings: settings)

I am testing on emulator , is it because of that I am using Emulator Audio Recording is not working

[DyaryRaoof]

Probably. I am not sure.

Hi , im having the same issue i tried the above solution.After change it the xcode build done correctly but giving errors in xcode output.I'm using an ios emulator could that be the problem? Do we need a physical device to test these?
