callAPI()

its not the problem, its the statments cannot be top level, thats what it shows, i think its file name or something.

I don't understand what's the problem here, it does work on Swift Playground. Put that in a func if you are trying this on the Xcode project.

yep i tested it with the playground as well something is wrong with my crap ill see what it is, im new to swift and took a big project as starter so i learn alot

Try with the updated source now. It should print the photos array onto the console.

yep working great just need to implement to UIColletion and good to go :) do u recomment collection? or tableView?

glad it worked, depends on the design though. TableView will do if it's just a list. Use collection if it's a grid layout.

okay cool thank you for all the help

bro can u help me with this? im trying to put it in UIViewColletion, and im newbie to swift, im trying to figure it out but couldn't.

what im trying to do is:
The first screen the user is presented with should host a continuous scrolling list of flickr thumbnails recently loaded to flickr.
When a photo thumbnail is clicked the app should open a new screen displaying the specific flickr photo

check this link out if you're trying to pass data to detail page: https://stackoverflow.com/questions/28430663/send-data-from-tableview-to-detailview-swift

i did go there but its talking about table view, and i want it all in collection view.

It has similar delegates, the rest should be the same. Or share the link of the repo and show what you've tried so far.

i just have button, textfield, and collectionView, i need to put all this response in the collectionView thats is, i dont have nothing to show because everything i tried is crap

Can u tell me what am i doing wrong?, like i said im trying to put the API response that gives me array, into a UICollectionView.
