Here are iOS Objective-C headers as derived from runtime introspection.

The headers were generated using RuntimeBrowser for iPhone.

You can search the headers with github search:

https://github.com/search?type=Code&q=repo:nst/iOS-Runtime-Headers+hack

You can compare versions based on their tags, see the tags page:

$ git difftool 6.0 6.1 .

You can use the headers this way:

NSBundle *b = [NSBundle bundleWithPath:@"/System/Library/PrivateFrameworks/FTServices.framework"];
BOOL success = [b load];

Class FTDeviceSupport = NSClassFromString(@"FTDeviceSupport");
id si = [FTDeviceSupport valueForKey:@"sharedInstance"];

NSLog(@"-- %@", [si valueForKey:@"deviceColor"]);

• Green == public
• Red == private
• Blue == dylib

The code to draw this picture is in https://github.com/nst/RuntimeBrowser/tree/master/tools/ios_headers_history.
