Thanks for creating and sharing this library with the world, it's proving quite helpful.

What plans (if any) do you have for supporting Swift 2.0?

Thanks.

Also another issue: /Users/.../Pods/AERecord/Sources/AERecord.swift:69:82: Class 'Stack' is internal and cannot be referenced from a default argument value (multiple time this issue for different methods/properties) /Users/.../Pods/AERecord/Sources/Query.swift:581:71: Static let 'defaultPredicateType' is private and cannot be referenced from a default argument value (multiple time this issue for different methods/properties)

I tested your classes in your test project AECoreDataDemo, and its working fine. Suggest me what I do?

This pull request adds iOS, tvOS and OSX targets with shared schemes (for installation via Carthage) and configures those to work as a dynamic framework. Also a section to the README about Carthage installation was added.

This should solve #8.

Hello @tadija, I've migrated the AERecord code base to swift 2.0 syntax. The migration tool wasn't very helpful here because we had a lot of do try catch usecases to handle. I've also removed a few as? conversions because most CoreData methods uses the proper classes now (rather than AnyObject).

Let me know if you have any questions or feedback.

I did a pod update and i started facing this error. This problem is on 3.0.0 on 2.1.0 it works fine

 private class func _firstOrCreateWithAttributes<T>(attributes: [String : AnyObject], predicateType: NSCompoundPredicateType = defaultPredicateType, context: NSManagedObjectContext = AERecord.defaultContext) -> T {
        let predicate = createPredicateForAttributes(attributes, predicateType: predicateType)
        let request = createFetchRequest(predicate: predicate)
        request.fetchLimit = 1
        let objects = AERecord.executeFetchRequest(request, context: context)

        return (objects.first ?? createWithAttributes(attributes, context: context)) as! T //Here i get the error
    }

ERROR

Could not cast value of type 'NSManagedObject_AccountDetails_' (0x7fd43ae881b0) to 'FeedbackChamp.AccountDetails' (0x1081b1220).

MY CODE

AccountDetails.firstOrCreateWithAttributes(["data" : readableJSON["result"]["hoteladded"].bool! ? 1 : 0, "detailName": "num_hotels"])

AccountDetails.firstOrCreateWithAttributes(["data" : readableJSON["result"]["num_restaurants"].int!, "detailName": "num_restaurants"])

AERecord.saveContextAndWait()

Please fix it as soon as posible

I believe the correct delete function is model.deleteFromContext() rather than model.delete() where model is an instantiated NSManagedObject subclass. I looked through the source to find a reference to delete() and deleteFromContext() was the closest I came to finding something similar.

If you wanted to implement the delete() function for simplicities sake, you could just map it directly to deleteFromContext() given that the context var is optional and automatically assigned to the default context if not set.

In order to be able to write

let user: User = User.firstOrCreateWithAttribute("id", value: 123)

or

func newUser() -> User {
    return User.firstOrCreateWithAttribute("id", value: 123)
}

instead of

let user = User.firstOrCreateWithAttribute("id", value: 123) as! User

or

func newUser() -> User {
    return User.firstOrCreateWithAttribute("id", value: 123) as! User
}

I've updated podspec file and added support for specifying NSSearchPathDirectory for method storeURLForName. The reason is that app cannot access Documents directory on real device, and CachesDirectory must be used.

I don't know if I'm missing the point here, but suspendAutomaticTrackingOfChangesInManagedObjectContext is definitely marked as private and therefore can not be changed from anywhere outside the AERecird.swift file.

Hi,

is there any chance of this (and AEXML) getting updated to Swift 1.2? All the other frameworks i am using already have a 1.2 branch. If there is no plan to do this i would it myself but otherwise it would be a waste of time :).

hey Marko,

i have an issue and i-m thinking that i doing something wrong with saving or creating/mapping CoreDataModels while getting data from a Webservice. Situation:

1. I download from a Webservice all users cardboxes and serialize the Json into an DTO Object and then map the DTO to the CoreData DBOCardBoxModel
2. ForEach downloaded and mapped Cardbox download the Cards async 2.1) When the Api Call is finished, serialize the Json into a DTO Object 2.1.1) Then i want create a new CoreDataModel when the DTO.cardNbr not exists, else get first and map then the properties from the dto to dbo 2.1.2) In the Mapper.Map(dto->dbo) i want to map all the properties and set relations, so in example a card can have multiple choice answers, so i want to create them and add this relation to the card

Exception throw at the firstOrCreateWithAttributes methode when my call was for example 25 times called, when it called 5 times the exception didnt throw. I think it is because the NSManagementObjectContext is not on each thread, how can i handle this?

Here is some of my Code: I using the following extensions:

• Api: http://vluxe.io/swifthttp.html
• JSON serialize: https://github.com/daltoniam/JSONJoy-Swift

Another question from me is where i place my the Save funktion? I¥m not shure about this. 1.) The Api Call that will call 25 Times: (the self.saveDB will call the saveAndWait(default) funktion)

public func ActiveCardBoxesById(dboCardBoxes : Array<String>){
        //let operationQueue = NSOperationQueue()
        //operationQueue.maxConcurrentOperationCount = dboCardBoxes.count
        for cardBox in dboCardBoxes {
            if self.CanSendRequest() {
                var request = self.CreateBaseRequest()
                request.requestSerializer.headers["clientid"] = self.UniqueId
                request.GET("/cardbox/\(cardBox)/cards", parameters: nil, success: {(response: HTTPResponse) -> Void in
                    if (response.responseObject != nil) {
                        //TODO
                        let dtoCards = Cards(JSONDecoder(response.responseObject!))
                        for dtoCard in dtoCards.cards! {
                            var dboCard = DBOCard.firstOrCreateWithAttribute("cardNbr", value: dtoCard.cardNbr!) as DBOCard
                            Mapper.Map(dtoCard, dbo: dboCard)
                        }

                        self.dataDelegate?.ConfirmLastSyncCardBox!()
                        self.logger.info("ConfirmLastSyncCardBox \(cardBox)")
                    }
                    }, failure: {(error: NSError, response: HTTPResponse?) -> Void in
                        self.logger.error("Getting ActiveCardboxesById throw error : \(error)")
                        self.baseDelegate?.ErrorInWebService(error)
                })


            }
            else {
                logger.warn("Can not communicate with API")
                self.baseDelegate?.ErrorSendingRequest()
            }
        }
        self.saveDB()

    }

2.) This is the Mapper.Map methode: (the self.saveDB will call the saveAndWait(default) funktion)

class func Map(dto : DTOCard, dbo : DBOCard) -> DBOCard {
        if let cardNbr = dto.cardNbr {
            dbo.setValue(cardNbr, forKey: "cardNbr")

I have got this error some times in my project using AERecord, would you please help me to fix it? I can't fix it by myself, I need your help! Very thanks!

Hi,

In the readme it is mentioned that AERecord supports iCloud. Besides notification references in the code, I could not find how to set up CloudKit syncing.

Is there any documentation or references regarding iCloud sync?

I've tried setting the mergePolicy by loading AERecord with the myOptions parameters, but the mergePolicy option or configuration is not read correctly.

Currently I'm using this code to set the mergePolicy, is this the best (or only) way to do this?

AERecord.Context.default.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy AERecord.Context.background.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy AERecord.Context.main.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy

Full loading code:

` let myOptions = [NSMigratePersistentStoresAutomaticallyOption: true, NSInferMappingModelAutomaticallyOption : true] do { try AERecord.loadCoreDataStack(options: myOptions) AERecord.Context.default.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy AERecord.Context.background.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy AERecord.Context.main.mergePolicy = NSMergeByPropertyObjectTrumpMergePolicy

} catch { debugPrint(error) } `

If I want to create an NSManagedObject in a background thread than EXC_BAD_INSTRUCTION (code=EXC_i386_INVOP, subcode=0x0) arise.

@discardableResult class func create(in context: NSManagedObjectContext = AERecord.Context.default) -> Self { let entityDescription = NSEntityDescription.entity(forEntityName: entityName, in: context)! let object = self.init(entity: entityDescription, insertInto: context) // error line Line 104 in Query.swift return object }

Part of my code: DispatchQueue.global(qos: .background).async{ let model = Model.create() }

Do you know what's going wrong? Thank you for your efforts
