UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData *data=UIImagePNGRepresentation(viewImage);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *strPath = [documentsDirectory stringByAppendingPathComponent:@"myimage.png"];
[data writeToFile:strPath atomically:YES];

Try the following:

UIGraphicsBeginImageContextWithOptions(myView.layer.frame.size, false, scale)
myView.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let viewImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()
let data = UIImagePNGRepresentation(viewImage)
let documentsDir = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as! String
let writePath = documentsDir.stringByAppendingPathComponent("myimage.png")
data.writeToFile(writePath, atomically:true)
