'Lost Connection' Randomly Occurring Swift

My app is Fetching CoreData strings and uiimages. I'm also capturing the camera's live feed and displaying it on a UIView. Randomly the device 'Lost Connection'. I have checked the memory and CPU Usage and nothing seems to be going wrong there.

lost Connection

I occasionally get these printout warnings

Received memory warning.

_BSMachError: (os/kern) invalid name (20)

_BSMachError: (os/kern) invalid name (15)

Communications error: { count = 1, contents = "XPCErrorDescription" => { length = 22, contents = "Connection interrupted" } }>

I've tried setting my Localization native development region in the Info.plist to United States as was widely suggested but not luck.

I'm running Xcode 9 BETA and iOS 10 on my testing device (iPod).

The way I was taking the picture returned a very high quality image (1000's of pixels). So when I passed the image in prepareForSegue and saved it using Core Data it was overloading the device.

So I used this code to reduce the size of the image and that worked.

func resizeImage(image: UIImage, newWidth: CGFloat) -> UIImage {
    let scale = newWidth / image.size.width
    let newHeight = image.size.height * scale
    UIGraphicsBeginImageContext(CGSize(width: newWidth, height: newHeight))
    image.draw(in: CGRect(x: 0,y: 0,width: newWidth,height: newHeight))
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return newImage!
}
