Could anyone please share a simple some instructions on just getting measurement updates. I didn't develop for a long time and getting back to it. Went through various courses quickly to catchup what I have missed, but I simply cant get CMWaterSubmersion manager even to build. I am following documentation, but making cookie mistakes and getting error after error net even being sure how many mistakes I did already. I am creating a separate class and adding trying to start monitoring data. Registered for motion data, edited plist etc. But then getting missing initializer or non conformation to CMWaterSubmersionManagerDelegate etc etc. Can find any simple code example anywhere on the internet.
