Science Journal for iOS allows you to gather data from the world around you. It uses sensors to
measure your environment, like light and sound, so you can graph your data, record your experiments,
and organize your questions and ideas. It’s the lab notebook you always have with you.

Required dependencies

First, you’ll need a Mac. We don’t support building the iOS app on anything else.

Second, you’ll need the latest version of Xcode installed.

Third, we use a few open source frameworks to build this app, so you’ll need to install CocoaPods as your package manager in order to get what you need to build.

Fourth, we use protobuf. You’ll need to install that too. We use Homebrew to install it.

Here are the steps to set up your environment:

  1. Install Xcode.
  2. Install CocoaPods by running sudo gem install cocoapods from your terminal.
  3. Install Homebrew by following the instructions on the Homebrew website.
  4. Install protobuf by running brew install [email protected]; brew link [email protected] -f from your terminal.

Building and running

Before you jump into coding, you’ll need to run pod install from the root of this project (the folder that contains has the Podfile file)

Then you can open ScienceJournal.xcworkspace

Note: there is a ScienceJournal.xcodeproj file, but since we use CocoaPods, you shouldn’t use that project file. If you do, nothing will work 😭
