Modifying Set via NSArrayController breaks Set in weird way

Got a strange issue here. I have a small model class that stores a NSNumber. @objc(Foo) final class Foo : NSObject { dynamic var x = 0 override init() { self.x = Int(arc4random()) } init(x: Int) { self.x = x } } In my ViewController, there is a NSSet-ba

As the comments in the sample project describe in the introductory comments, modifying the code to force an NSSet does not solve the problem. > On 08 Jan 2016, at 18:39, Quincey Morris > wrote: > > On Jan 8, 2016, at 07:14 , Etan Kissling > wrote: >> >> In my View

In fact, it makes things even worse, and freezes up Xcode when expanding the set in the debugger. > On 08 Jan 2016, at 18:59, Etan Kissling wrote: > > As the comments in the sample project describe in the introductory comments, > modifying the code to force an NSSet does not solve the problem.

Re: Modifying Set via NSArrayController breaks Set in weird way

Wow, thanks for the various hints. a. Could be :-) However, since the Find feature of the minimal app stops working properly after modifying the collection, there's definitely something fishy. b. Yep, the dynamic keyword can afaik only be applied to types that are representable in objc. c. Hm

Obtaining a value from a hex representation

A user enters the hexadecimal representation of a number like "0x31C8FD" into a text field. The intValue of such strings is 0. Is there a Cocoa method (like .hexValue) to convert the hex representation string into a value? -Carl ___ Cocoa-dev mailin
