Compiler ErrorThis week's Compiler Error has a theme: AltStore facts!
1 - AltStore works by re-signing the apps you download with your own Apple ID, making them unique to you, but they need to be re-signed before 7 days pass.2 - AltStore gets around installation limits for free developer account by running a server on your Mac to install it through iTunes’s WiFi Sync.3 - Since free developer accounts are limited to 3 apps per device, AltStore first uninstalls all provisioning profiles, installs the new app, then re-installs the other profiles.4 - AltStore also runs on Windows and Linux, with the added benefit that iTunes is not required for the installation of apps.1 hr 23 min - 66: Awesome Interviews Done Quick
