You are not using the documents directory but the documentation directory. Use this NSDocumentsDirectory instead of NSDocumentationDirectory. Or even better, use the caches directory NSCachesDirectory because documents directory sync with iCloud and Apple might not like it since Documents directory should contain only user-downloaded files.
