This is a small project which I never ended up finishing. I thought you folks might appreciate it
I used to daily drive an iPhone 5 with iOS 6 installed via coolbooter, but I missed using Discord on the go. I built this bare-bones client for it, but gave up on using such an old platform before the app got very far. Still a fun experiment.
It's so bare-bones that it isn't really worth using. You'll need an old version of Xcode running on an old version of OSX. I recommend the last version of Mavericks & Xcode 5 with the iOS 6 sdk manually copied from Xcode 4.3.
