“SwiftData inheritance relationship”

I pass a object from another viewcontroller and try to add a new record on coredata, object is not nil , but I got the error message below, why? What is that mean in different contexts?'NSInvalidArgumentException', reason: 'Illegal attempt to establish a relationship 'schedule' between objects in different contexts

Information NeededWe began the review of your app but aren't able to continue because we need additional information about your app.At your earliest opportunity, please review the following question(s) and provide as much detailed information as you can. The more information you can provide upfront, the sooner we can complete your review.1. What is the developer's relationship to Kim? Please provide detailed information.------------------------------------------------------------------------------------------------------------------------------Kim is our client. He requested me to make this app. (his personal app, He is a celebrity.)Is this infomation above enough? I don't know what kind of detail information apple reviewer want? Thank for your help.

Here is my problem:I`ve got a project already,today i had it cococPods managed for i want to useReactiveCocoa in my project.After i set up the pod,and build it,this error occured;ld: library not found for -lReactiveCocoaI have checked the Target`s Library Search Paths setting ,it seems allright;$(inherited)So i was confused.I want to konw where did it inhrit with?

(This is part of my larger desire for Swift to have explicit code-generation support, since we don't get macros anymore)For instance, say I've defined a Point type:struct Point2D<T: ScalarType> : CustomStringConvertible, Equatable { //Yes, I know there's no such protocol as ScalarType. Hint, hint... nudge, nudge... var x: T var y: T var description: String { return ((x), (y)) } } func == <T: ScalarType> (lhs: Point2D<T>, rhs:Point2D<T>)-> Bool { return lhs.x == rhs.x && lhs.y == rhs.y }and I want a Vector2D type. The easiest way would be a typealias:typealias Vector2D = Point2D<Double>But then when I write the dot product functionfunc * (lhs: Vector2D, rhs: Vector2D) -> Double { return lhs.x * rhs.x + lhs.y * rhs.y }... code likelet v = Vector2D(x: 3.0, y: 1.2) let p = Point2D(x: 1.0, y: 1.3) let foo = v * p... will compile even though, at least semantically speaking, it breaks Swift's type-safety.Obviously, this is a pretty trivial example, but in the general sense

I'm new to app development and have inherited a project which I am currently updating to Swift 2.1.I've cleaned up all compile errors except this last one, and need some help. The section of code I'm having problems with is as follows:if application.respondsToSelector(registerUserNotificationSettings:) { let testAction = UIMutableUserNotificationAction() testAction.identifier = TEST_ACTION testAction.title = Reply testAction.activationMode = .Background testAction.authenticationRequired = false testAction.destructive = false let category = UIMutableUserNotificationCategory() category.identifier = CATEGORY_ID category.setActions([testAction], forContext: .Default) category.setActions([testAction], forContext: .Minimal) let categories = NSSet(object: category) as! Set<UIUserNotificationCategory> let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: categories) application.registerUserNotificationSettings(settings) }The line...let settings = UIUserNotificationSe

I'm posting this in this forum because it will get more attention here. If I have two record types with a one-to-many relationship does the owner (one) record have to have a CKReference field or just the owned (many) record? If the owner record has a CKReference field, what is that field set to in the owner record?

Writing constrained versions of existing protocols seems like a basic and useful thing to do, yet I keep running into problems when trying. I'll try to explain what I mean by an example:Let's say we need a protocol that is exactly like GeneratorType except that its Element must be an IntegerType.I might be missing something but I'm guessing that this is the way to express that in Swift:protocol IntegerGeneratorType : GeneratorType { typealias Element: IntegerType }We could make a GeneratorType based protocol with even harder constraints on its Element, eg that it must be Int:protocol IntGeneratorType : GeneratorType { typealias Element = Int }Now, let's add a default implementation of a method called squaredNext to the latter example protocol:extension IntGeneratorType { mutating func squaredNext() -> Int? { guard let someNext = next() else { return nil } return someNext * someNext // Error: Binary operator '*' cannot be applied to two 'Self.Element' operands. } }I can't see the reason for that error.

Hi, I'm wondering if anyone can help me. I'm looking into the feasibility of linking a series of ibeacons at hinge points on the body linked to the apple watch to essnetially provide a motion capture environment for sports coaching. However, as this is all quite a new area, I can't work find enough information on the feasibility of this. I was wondering if those experienced with iBeacons can give me the benefit of their experience on this.I'm looking at two feasibility studies:1, 12 ibeacons would be located at various parts of the body linked to apple watch on wrist and iphone in pocket. Via the custom app, the ibeacon locations could be drawn together in appropriate relationship to form a wireframe skeleton. The app would record 3D video of the sports activity to allow for a new perspective on sports coaching. The nearest thing I've seen to this usage is here: http://techcrunch.com/2013/11/24/notch/2, The second feasibility study would be if the above did not meet feasibility requirements. In this
