I still haven't figured out how to make this work in Swift. Here's some
more complete examples that show how I've tried to do it
import Foundation
class ArrayItem : NSObject, CBLJSONEncoding {
let holding: Int
init(holding: Int) {
self.holding = holding
}
required init(JSON jsonObject: AnyObject!) {
self.holding = 0
}
func encodeAsJSON() -> AnyObject! {
return ["holding": self.holding]
}
}
class TestModel : CBLModel {
@NSManaged var itemArray: [ArrayItem]
@NSManaged var simpleArray: [Int]
class func all() -> CBLQuery {
let query = databaseMain.viewNamed("allTestModels").createQuery()
return query
}
class func itemArrayItemClass() -> AnyClass {
return ArrayItem.self
}
convenience init() {
self.init(newDocumentInDatabase: databaseMain)
itemArray = [ArrayItem]()
simpleArray = [Int]()
type = "TestModel"
}
}
That declares the model object. Here is an example that will look up the
objects and try to access the properties. When it tries to access the
property named itemArray, it causes a fatal error.
func runModelTests() {
var error: NSError?
let queryEnumerator = TestModel.all().run(&error)
assert(error == nil, "Unable to query all TestModels")
while let row = queryEnumerator.nextRow() {
let testModel = TestModel(forDocument: row.document) as TestModel
println("properties: \(testModel.document.properties)")
println("simpleArray: \(testModel.simpleArray)")
// Here's where we access the array of objects and get...
// fatal error: NSArray element failed to match the Swift Array
Element type
println("itemArray: \(testModel.itemArray)")
testModel.deleteDocument(&error)
assert(error == nil, "Unable to delete TestModel")
}
let testModel = TestModel()
testModel.simpleArray.append(0)
testModel.simpleArray.append(1)
testModel.itemArray.append(ArrayItem(holding: 10))
testModel.itemArray.append(ArrayItem(holding: 11))
testModel.save(&error)
assert(error == nil, "Unable to create test model")
println("Created TestModel: \(testModel.document.properties)")
}
