I suspect this can't be done (at least not right now), but wanted to check.
I'd like to declare a class as a generic that meets a protocol and is also a
subclass of some specific type.
Something like class Foo (i.e., the T must be
both a NSManagedObject or subclass of it and conform to SomeProt
I’m teaching an iOS with Swift this semester and one of my students pointed out
that:
struct Person {
var firstName: String
var lastName: String
}
does create a default initializer that you can call as:
p = Person(firstName: “Dave”, lastName: “Reed”)
but if you write:
public struct Perso
This would probably be better-suited on the Xcode list than here as I think
it's a bug in Xcode.
I've had issues when trying out this new CoreData codegen feature. What fixes
it for me is to go to:
~/Library/Developer/Xcode/DerivedData
and delete the entire directory for the build of my projec

I'm trying to convert the following code (from the Big Nerd Ranch's Freddy JSON
parser) that works in Xcode 8 beta 5 and convert it to work with beta 6.
Essentially it appears it needs to take a Data object and convert it to a
UnsafeBufferPointer if I understand it correctly.

I was updating my project from beta 3 to beta 4 today and it seems
AttributedString disappeared. Changing it to NSAttributedString fixed it.
I don't see anything in the Release Notes about AttributedString.
Is it gone permanently? Or am I doing something wrong?
Thanks,
Dave Reed

Joe,
I had an expression that worked fine with Swift2.2 but Swift3 (Xcode 8 version)
complains it's too complex:
The variables are of type CGPoint and the function returns a Bool.
return (pt.x - p0.x) * (p1.y - p0.y) - (pt.y - p0.y) * (p1.x - p0.x) < 0.0
Thanks,

I've got a project I had been working on using Swift2.2 and decided to migrate
to Swift3 (using Xcode 8 beta) before the project gets any bigger. I
successfully migrated everything except I have a CGContext for writing to a PDF
and calls the endPage() method. For that the compiler responds with
