Hello,
Did you find the solution?
In my case Image is getting nil and when I try to add into the array its getting crashed.

I want to know why delegate method Image object is getting nil.

Thanks.

No, did not
I use OpalImagePicker instead, compatible with both Swift and Objective-C.(https://github.com/opalorange/OpalImagePicker)
