How to create an Array UIImage in Swift [duplicate]

Question

This my code

var changePhoto = [UIImage]()
let photoPng = UIImage(named: "1.png")
let photoJpg = UIImage(named: "1.jpg")

changePhoto += photoPng
changePhoto += photoJpg

but error "expected declaration"

Please help me! What's wrong?

You need to use the append method to add new objects to your array:

changePhoto.append(photoPng)
changePhoto.append(photoJpg)

Also, you only can have functionality inside of methods. So try to call it inside a method. for example if you use a Viewcontroller in your viewDidLoad method.

I already use that code. But it's not done. Same error. I'm using Xcode 6.3 beta 4. But in my opinion it's not issue.

Try changePhoto.append(photoPng!)

@MinhThắngTrương Check my update. Maybe you call it outside of a function. That's not allowed. You can only use functionality inside a method.

@Christian! Thanks! that's exactly excuse.
