Hello there Troy,
We currently have a problem with the self-deploying version of the 5.0 Reviewer App not working with the latest version of Xcode.
Below is a download link containing the Reviewer App within a .zip file that you can manually install to the 7.0.3 iOS Simulator version. To install this, hold the Option key and use the top menu bar from the Finder and select "Go" and then "Library", then navigate through the folders to Application Support -> iPhone Simulator -> 7.0.3 -> Applications and copy/move the "MagReviewer" folder there. Then you manually have to run the simulator from Xcode, making sure you are using the 7.0.3 device. You will find the Mag+ Reviewer App now installed on the second page of your Simulator.
