I try to translate this code:
[[VKSdk instance] setUiDelegate:self];
i tried so:
VKSdk.instance().setUiDelegate(self)
But this is wrong!
Please help!

From where do you have the Objective-C code above? I have quickly read over the frameworks.h file and did not find something like that.
But I did find this:
VKSdk.initializeWithDelegate(self, andAppId: "")
Is that what you are searching for? Or does it have to be the setUIDelegate?
UPDATE
Wait I have found something else...
VKSdkUIDelegate Protocol.
Please try this:
VKSdk.instance().uiDelegate = self

Cannot understand why does SIZE work in itself, but not in an UDF. The output is IntegerType as it can be seen in the top picture.
Works with max for example.
#samkart your function should be a python function, not a native spark one.
Ah ok, this explains it.
Just curious, where is this mentioned in spark documentation?

Is there a way to get your fiddles to have a URL with the name you choose in the fiddle options. For example, I think I should be able to have this fiddle use "Utility" in the URL rather than cose65dh.
Is it possible?
Dummy code to include fiddle:

No, the settings page does not have any settings to change the URL that is generated.
