XCode simulator won't run most recent code

I've been writing an app and I've released one version to the app store. I've updated it slightly since then and have been playing with it on the simulator. Unfortunately the simulator has stopped reacting to my changes in code. I know it's the simulators fault because if I run the app on my ipad the changes take effect.

I've tried resetting the simulator by going iOS simulator -> reset content and settings I've tried quitting out of the simulator I've tried quitting out of xCode

I have no clue why the simulator is wrong. It's just blatantly not updating. I wish I could give more details but I really don't know much more.
