Swift: Uploading Image to Firebase Cloud Storage When User Closes App

Memory crash with uploading image to Firebase Storage Swift

You need to resize your image to a lower size. We all know that photos captured by ios devices is quite large and sending it as data to a server is also a big workload. You can resize the image to your liking without losing most of its quality.

Check this out for resizing.

Swift app crashes when uploading image to firebase

It looks like you forgot to use the child storage node you just created. As such, try replacing this code:

thumbnailStorageRef.child("thumbnails/" + randomString(length: 20) + ".png")
thumbnailStorageRef.put(imageData, metadata: nil, completion: ...

with this instead:

let imageRef = thumbnailStorageRef.child("thumbnails/" + randomString(length: 20) + ".png")
imageRef.put(imageData, metadata: nil, completion: ...

This change should fix your current issue ;)

Image not uploading to Firebase Storage

Since I forgot I had a @State var avatarImage = UIImage(systemName: "person.fill")! inside a struct of type View, it was taking the picture the user selected and doing nothing, because the code was taking another @State var as the picture with the info, to upload to Firebase (debugger showed self.image was throwing nil).
