White Screen When Launching App Without Display of Images in Asset

[ndgsghdj]

Launching the app, the images in the Assets folder would not be displayed on the app

Furthermore, when pressing the "Add" ("+") button to add pictures, it seems that I get an error like this:

I had expected the image to display as I had put an element in the Photos array in Photo.swift with an image name filled out as well as the image being put in the Assets folder. However, it still seems to not display.

Can you send the xcode file? @ndgsghdj

There shouldn't be 2 classes of the same file. You declared a class on both line 12 and 141. Delete line 141 to 144 and add the delegates for the navigation controller and image picker controller. In addition, you should put the code properly. Functions should not be put in view did load and instead, outside of that view did load function. Not only that, in the numberOfItemsInSection function,you should not return zero and instead, the number of images in the image array. LAstly, add constraints on your collection view cell or else it would end up like

refer to slide 19 in iOS Lesson 5 on the constraints https://docs.google.com/presentation/d/1k16mNd9lUCUlMzqqarB9CurlZBIo4egLyDhgVN-8TFM/edit#slide=id.gfab7606283_0_11

if you need help with constraints, reply and ping this thread.

Hi @ndgsghdj,
If you're referring to the constraints section of the Size Inspector, this might help

To create constraints, I would recommend using this which is on the bottom left of ur main storyboard

Hope this helps
