Logging
The SDK logs messages to standard out, but by default does not log to a file. It is strongly encouraged to enable logging to a file. This may be done like so:
Objective-C Swift
ASLogBackendFile *fileBackend = [[ASLogBackendFile alloc] init];
[fileBackend openLogAtPath:@"/path/to/log/file"];
[[ASLog defaultLog] setLogBackend:fileBackend];
The logs will be written to the indicated file. Such log files are indispensable when analyzing transfer behavior and performance.
