Solved: Ionic ENOENT Invalid device state error when using sudo on Mac

I was trying to launch a sample app on the newly released Ionic 2 Release Canditate. When I ran the command sudo ionic run ios --emulator, I encountered an error similar to this one which I shorted for display here:
An error was encountered processing the command (domain=com.apple.CoreSimulator.SimError, code=163):
Invalid device state

Error: ENOENT: no such file or directory, stat '/Users/.../Library/Logs/CoreSimulator/.../system.log'
After searching the internet for solutions, I was able to overcome the error by taking the following steps:

  1. Install the latest update to Xcode.
  2. Run xcode-select --install to make sure that Xcode command line tools is installed (as recommended by Mike Hartington on the Ionic Github page.)
  3. Run sudo chown -R username /Users/username to update my permissions which makes it so that I don't have to run sudo when running ionic commands (as recommended by Zac Vineyard on his blog.)
  4. Run ionic run ios --emulator (this time without using sudo).
Thank you for the help guys!

Parameters Sent by TinyWebDB in App Inventor for Android

TinyWebDB is a component in App Inventor for Android that lets your app communicate with a web page in order to set or retrieve values, rather than storing them on the phone itself. I wanted to know what the TinyWebDB component sends to the web page when it tries to set or retrieve values, so I used Kodingen this morning to write a PHP script that takes the form fields and values sent to the page and writes them to a file. Here is what I found: TinyWebDB.StoreValue sends these parameters: tag value TinyWebDB. GetValue sends this parameter: tag So if you write your own PHP page for TinyWebDB to connect to, you can know if TinyWebDB is trying to store a value if the "value" key exists in the $_POST array. If the "value" key doesn't exist in the $_POST array then you know that TinyWebDB is only trying to retrieve the value for the given tag. As an alternative to using the method outlined by Google , you could use TinyWebDB with your own script written in an
