I’m not a programmer, and it’s unlikely I’d succeed, but I enjoy dabbling in programming and wondered if I can make a little app for myself, for my own personal use, not to sell or publish on the App Store. With out having to $99. I’ve installed Xcode, and have a sample app I got from Adafruit on connecting to a Bluetooth device to be able to control something like turning on/off a device. It will build in the simulator but not when I try to install it on my phone.
