How to clean up all cache files?

[joe528]

If I want to manually clean up the cache (delete all temporary files), is this the correct way to do it?

Cache.shared.removeAll()

The users sometimes want to manually delete all temporary files because they don't like to see an app occupies too much space in their iPhone.

Cache.shared.removeAll()

That's memory cache only.

Cleaning disk cache isn't that trivial. Disk cache is whatever DataLoader uses. Default DataLoader creates and uses an instance of URLCache:

 private static func defaultConfiguration() -> URLSessionConfiguration {
    let conf = URLSessionConfiguration.default
    conf.urlCache = URLCache(memoryCapacity: 0, diskCapacity: (200 * 1024 * 1024), diskPath: "com.github.kean.Nuke.Cache")
    return conf
}

In the current Nuke version you don't have access to that URLCache instance. You'll have to initialize your own DataLoader with your own URLCache to have access to it.

Disk cache will be cleaned up automatically & periodically by Nuke or by iOS?

Yes. And the default 'URLCache' created by Nuke has a 200 Mb limit. If you find it to be to large, just use a custom 'DataLoader'.
