KZFileWatchers

Wouldn’t it be great if we could adjust feeds and configurations of our native apps without having to sit back to Xcode, change code, recompile and navigate back to screen we were at?

One of the basis of building tools that allow us to do just that is the way we observe for data changes, this micro-framework provides you File observers for Local and Remote assets.

This framework provides:

• FileWatcher.Local useful for observing local file changes, it can also be used to breach Sandbox env for debug simulator builds and e.g. observe file on the developer desktop (like the demo app does).

• FileWatcher.Remote can be used to observe files on the web, it supports both Etag headers and Last-Modified-Date so you can just put file on Dropbox or real ftp server.

It also supports usage from Objective-C projects. For this, you should consider these following steps:

1. Add $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME) into your projects Library Search Paths in Build Setting section.

2. Import swift-header by adding @import KZFileWatchers; into any .m file, where you want to use FileWatchers.

3. Use provided classes for set up file observing like this:

self.fileWatcher = [[LocalFileWatcher alloc] initWithPath:path];
self.fileWatcher.delegate = self;
[self.fileWatcher startWithError:nil];

4. Implement FileWatcherDelegate in your class for handling file refreshing events. For example:

- (void)refreshDidOccurFrom:(id<FileWatcherProtocol>)fileWatcher type:(enum RefreshResult)type data:(NSData *)data
{
    self.textLabel.text = [[NSString alloc] initWithData:data encoding:kCFStringEncodingUTF8];
}
