How to append images to array from directory?

I use this code to append images in array from directory

for myIndex in 1...17 {
                
    let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
    let nsUserDomainMask = FileManager.SearchPathDomainMask.userDomainMask
    let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
    let dirPath = paths.first
    let imageURL = URL(fileURLWithPath: dirPath!).appendingPathComponent("\(index)/\(myIndex).jpg")
    let image = UIImage(contentsOfFile: imageURL.path)
    imageArray.append(image!)
                
}

but I have this error:

Thread 1: Fatal error: Unexpectedly found nil while unwrapping an
Optional value

imageArray.append(image!)

How to fix it?

>Solution :

It’s pretty clear. You’re forcing unwrap image with ! in the case of nil. So, I think you should:

1. Unwrap the image in a safe way such as if let or guard let:

if let image = UIImage(contentsOfFile: imageURL.path) {
    imageArray.append(image) //without "!"
}

2. Double check why the image’s path is nil.

You can take a look at the app’s container. If you saved the image successfully, it should be there.
