Initializer for conditional binding must have Optional type, not '() -> Data?'
I am having an issue where I want to upload an image to the Firebase storage/database. I am receiving this issue when I create this line of code:
if let uploadData = UIImage.pngData(self.profileImage.image!) {
}
The error for this line is as the title states: Initializer for conditional binding must have Optional type, not '() -> Data?'
Any suggestions for how to remedy this?

You can try
guard let uploadData = profileImage.image?.pngData() else { return }
if you need if let
if let uploadData = profileImage.image?.pngData() {
}
pngData() is an instance method of UIImage instance
https://developer.apple.com/documentation/uikit/uiimage/1624096-pngdata
in your code you consider it a class method which isn't correct
