I usually mark my target-action methods like so:
private dynamic func didTapNext(sender: UIButton)
"dynamic" makes the compiler generate code for dynamic dispatch, that is
runtime message passing, like objc. The "private" part doesn't change that,
it just reduces clutter.

I'm sure people here know about the problem that AnySequence, AnyGenerator,
etc solves.
In Swift, a protocol can have an associated type, which is kinda like
generics, but you cannot declare a variable like this:
let sequence: SequenceType
If you want a sequence, any sequence, over ints you need
This is even worse if I want to create a singleton, and ensure that the
only way to access it, is through a static let on the class:
class Singleton: NSObject {
static let instance = Singleton()
private override init() {
super.init()
}
}
In Swift, I can't instantiate this clas
Hi,
In Objective-C, I've often attributed initializer from super classes as
unavailable. Like this;
@class Dependency;
@interface SomeClass : NSObject
- (nullable instancetype)init __unavailable;
- (nonnull instancetype)initWithDependency:(nonnull Dependency *)dependency;
@end
This makes the
