Simple UIImage Caching in Swift


This is a snippet of code that will cache images downloaded from an online source, and provide them when needed. I still have some work to do on it, but right now it works pretty fine.

I’m using a dictionary to keep track of the images, with their Base64 encoded urls as keys.

Example usage goes like:

PS: Also, that UIImage().loadAsync is an UIImage Extension method I have lying around 🙂

Change font weight by code in Swift


This snippet changes the current font of a label to a Light version of it ( in case it exists ). Font names are ( in this case, it was ‘.HelveticaNeue-Regular’ ) appended with their weight. So I get the font name, split it by ‘-‘, and take the first part of the split, ending with ‘.HelveticaNeue’. Now I just create a new font with the light appended to it, with the same size.

Lastly, I switch the font, and there you go.
