You can't do this yet. Required initializers must be implemented in the
main class body, and NSCoding has a required init(coder:) initializer.
Hi All,
I need to extend a class for NSCoding protocol conformance.
I tried the following code in the playground and get an error - required
initialiser cannot be declared in the extension. If I do not make it
required, I get an error asking to make it required ...and so on
class first
From the documentation:
...
A default’s value must be a property list, that is, an instance of (or
for collections a combination of instances of): NSData,NSString,
NSNumber, NSDate, NSArray, or NSDictionary. If you want to store any
other type of object, you should typically archive it to c
Hi,
Question about registering defaults - I'd assumed the following would
be valid, assuming that GuideSettings implements the NSCoding protocol

If you want to get really fun, you can check it thus:
if([super.class instancesRespondToSelector:...])

The line for S3 is wrong since you presumab
Thanks for your replies.
But now I'm confused about how to de-allocate MyClass. Given this in
its initialisation:
S1 = @"a string";
S2 = [[NSString alloc] init];
S3 = [NSString string];
I would only release S2 in the dealloc method. But if the class has

So finally, my question: am I right to retain S2 and S3, and not S1?
No. -decodeObject: and -decodeObjectForKey: always return autoreleased
objects, so if you use them later, then you must retain them unless
the code requires GC.

I want MyClass to conform to the NSCoding protocol. But I'm puzzled
about how to implement the initWithCoder: method.
Suppose I have this in MyClass.h:
NSString *S1, *S2, *S3;
and this in its init function:
S1 = @"a string";
S2 = [[NSString alloc] in
