SQLite error code:7, 'out of memory'

Hello Louis,

I found finally the problem. This is the snippet:

...
do {
    try FileManager().moveItem(at: location, to: destinationUrl)
    let data = NSData(contentsOf: destinationUrl)
    DispatchQueue.main.async {
        let soundSave : SelfieObject = SelfieObject.new()
        soundSave.url = url.absoluteString
        soundSave.path = destinationUrl.absoluteString
        soundSave.data = data as? Data
        soundSave.save()
    }
} catch let error as NSError {
    Log("An error occurred (step2): \(error.localizedDescription).")
}
...

Crash occurres in soundSave.save() because the phone is out of memory.

Do you have any advice, how can I catch this error from CDHelperEntity.swift class ?

could not locate an entity named 'User' in this model.'

I now tried to implement this helper twice and both times I got this error when I try to make a new User

'NSInternalInconsistencyException', reason: '+entityForName: could not locate an entity named 'User' in this model.'

I initiate in application did load using
CDHelper.initializeWithMainContext(self.persistentContainer.viewContext) // New XCode 8/Swift 3 template

I have the model swift class for User
Core data works fine but not with this helper :( any ideas?

Swift 2.3 in Xcode 8

I got an error when using Swift Xcode 2.3 on 8

Type ‘Self’ does not conform to protocol ‘NSFetchRequestResult’

Throw en exception if no more space in sqlite ?

Hello,

I would suggest to add a feature getting the lib able manage the lack of free space on the phone for saving. The idea is to catch this exception not in the library but in the code calling the library function (//HERE comment in the next snippet).

...
do {
    try FileManager().moveItem(at: location, to: destinationUrl)
    let data = NSData(contentsOf: destinationUrl)
    DispatchQueue.main.async {
        let soundSave : SelfieObject = SelfieObject.new()
        soundSave.url = url.absoluteString
        soundSave.path = destinationUrl.absoluteString
        soundSave.data = data as? Data
        soundSave.save() // HERE
    }
} catch let error as NSError {
    Log("An error occurred : \(error.localizedDescription).")
}
...
