AFError

AFError is the error type returned by Alamofire. It encompasses a few different types of errors, each with their own associated reasons.

public enum AFError

Inheritance

Error, LocalizedError

Enumeration Cases

createUploadableFailed

UploadableConvertible threw an error in createUploadable().

case createUploadableFailed(error:​ Error)

case createURLRequestFailed(error:​ Error)

downloadedFileMoveFailed

SessionDelegate threw an error while attempting to move downloaded file to destination URL.

case downloadedFileMoveFailed(error:​ Error, source:​ URL, destination:​ URL)

explicitlyCancelled

Request was explicitly cancelled.

case explicitlyCancelled

invalidURL

URLConvertible type failed to create a valid URL.

case invalidURL(url:​ URLConvertible)

responseSerializationFailed

Response serialization failed.

case responseSerializationFailed(reason:​ ResponseSerializationFailureReason)

serverTrustEvaluationFailed

ServerTrustEvaluating instance threw an error during trust evaluation.

case serverTrustEvaluationFailed(reason:​ ServerTrustFailureReason)

sessionDeinitialized

Session which issued the Request was deinitialized, most likely because its reference went out of scope.

case sessionDeinitialized

sessionInvalidated

Session was explicitly invalidated, possibly with the Error produced by the underlying URLSession.

case sessionInvalidated(error:​ Error?)

sessionTaskFailed

URLSessionTask completed with error.

case sessionTaskFailed(error:​ Error)

urlRequestValidationFailed

URLRequest failed validation.

case urlRequestValidationFailed(reason:​ URLRequestValidationFailureReason)
