I know nothing about swift, never developed an IOS app, so I’ll fork my own as I have wanted to learn about app development for some time now but was looking for reason / idea. Ill try to enhance, eventually I’ll contribute to the main project in a meaningful way.
You have a jailbroken iPhone or something? If not you should upgrade just for the security and bug fixes. It’s more important than ever due to how much personal and financial data that’s on your phone.
