I wrote this code up to Xcode7, but
Type 'VideoDelegate' does not conform to protocol 'AVCaptureFileOutputRecordingDelegate'
I have never received an error like this.
Can't I use it with Xcode8Swift3?
This is because the Swift3 naming convention has changed the external argument name and type.
class VideoDelegate:NSObject, AVCaptureFileOutputRecordingDelegate{
func capture(_captureOutput:AVCaptureFileOutput!, didFinishRecordingToOutputFileAtoutputFileURL:URL!, fromConnections connections:[AnyObject]!, error:NSError!){
print("capture output: finish recording to\(outputFileURL)")
}
func capture(_captureOutput: AVCaptureFileOutput!, didStartRecordingToOutputFileAtoutputFileURL:URL!, fromConnections connections:[AnyObject]!) {
print("capture output:started recording to\(outputFileURL)")
}
}
You must add _ to make it clear that the first argument label is no longer omitted and that you do not want to take the argument label instead.
didStartRecordingToOutputFileAtURL: changed to didStartRecordingToOutputFileAt: and NSURL changed to URL.
AVCaptureFileOutputRecordingDelegate definition should be reviewed quickly.
