Get App Running in Xcode and Android Studio

iOS

1. Open ios/MushroomObserver.xcworkspace in Xcode
2. Assign the Signing Team. Select Navigate -> Reveal in Project Navigator. Click "MushroomObserver" is the left hand panel. Then select the Signing & Capabilities tab. I already had "Mushroom Observer, Inc." configured in Xcode. I believe you can add it by clicking the drop down next to "Team" and selecting "Add an Account". I expect you'll need the Apple ID credentials for MO if you need to build a real version of things. However, you should be able to setup a personal team using your own Apple ID credentials.
3. In the Project Navigator, select the "Build Settings" tab and search for "enable_user". Select "No" for "User Scipt Sandboxing". This should turn off ENABLE_USER_SCRIPT_SANDBOXING.

4. Select a reasonable iOS Simulator from the pulldown at the top of the screen. I chose "iPhone 15".
5. Click run button.
6. PROFIT!!!

Android

1. Open the "android" directory in Android Studio.
2. Should kick off build.
3. Click run button.
4. PROFIT!!!
