[swift]IOSアプリによるAWS(S3)への画像アップロード

Question

###前提・実現したいこと
AWS（アマゾンウェブサービス)のS3というストレージに画像をアップロードするIOSアプリをswiftで作成しています。
###発生している問題・エラーメッセージ

画像をDocument以下に保存し、リサイズしない場合はアップロードができるが、リサイズや、ダウンロードした画像のみがアップロードできない。
パスには問題がなく、きちんとデータも存在していることは確認してます。

fail

###きになるエラー
CFURLResourceIsReachable failed because it was passed an URL which has no scheme
というエラーがおそらく解決する手がかりだとは思うのですが、
CFURLというのがみつからない、URLが間違えているという意味だと思うのですが、NSURLはまちがえていないはずなのですが、、

Answer 1

まさか自己解決いたしました。
ディレクトリパスの冒頭のfile:///をつけ忘れるという初歩的なミスでした。
