Simple Painting Application - Work Time

So upon deciding to come into uni once again with our minds already bustling with ideas and already on track from having to work on it yesterday we came in discussing our ideas first to enhance everything we already had. Mutually we decided that we wanted to implicate a function to change the width of our lines. So we had to do this through xCode of course and we attempted to change the width by inputing the code of line width in CGContext with applying a set number in front of the set color. But this resulted in every line coming up as a single width regardless of what we entered so eventually but unfortunately we agreed that width was something that we weren't able to implicate despite how much we wanted to so this meant that of course we had to move on to a new idea to implicate but after spending the day on width and having to leave reasonably early there was nothing else we could do today but think up of what was possible.
