I'm running into a weird error with a for in loop and an array. it says
For-in loop requires '[DeepSpeechTokenMetadata]' to conform to 'Sequence'
Which doesn't make any sense... it knows it's an Array...
The for loop in question:
var transcriptCandidate = decoded.transcripts[0].tokens
var words = [String]()
var timestamps = [Int]()
var workingString = ""
var lastTimestamp = -1
for (x, token) in transcriptCandidate {
let text = token.text
let timestamp = token.startTime
if(lastTimestamp == -1){
lastTimestamp = timestamp.toInt()
}
Here's the definition of the class that contains the array I'm trying to iterate through:
public struct DeepSpeechCandidateTranscript {
/// Array of DeepSpeechTokenMetadata objects
public private(set) var tokens: [DeepSpeechTokenMetadata] = []
/** Approximated confidence value for this transcript. This corresponds to
both acoustic model and language model scores that contributed to the
creation of this transcript.
*/
let confidence: Double
internal init(fromInternal: CandidateTranscript) {
let tokensBuffer = UnsafeBufferPointer<TokenMetadata>(start: fromInternal.tokens, count: Int(fromInternal.num_tokens))
for tok in tokensBuffer {
tokens.append(DeepSpeechTokenMetadata(fromInternal: tok))
}
confidence = fromInternal.confidence
}
}
Thanks!
You can either do this, where x
is the index and token
is the element:
for (x, token) in transcriptCandidate.enumerated() {
}
Or this if you don't need the index:
for token in transcriptCandidate {
}
