Apple is well known for testing its upcoming iOS versions first with the developers before they are released to the public. This is the reason why the Cupertino based company introduces new versions of iOS for developers very often, in order to get as much information as they can from them. This way, they will be able to release a more bug-free iOS public version.
If you are a member of the Apple Developer program, then you will understand how hard it is to manage different devices and install Apple’s pre-released versions of iOS on them.
First of all, you will need to download the IPSW firmware file from Apple Developer website. After that, you will need to connect your device to iTunes and manually install the new iOS BETA version on your Apple device.
However, we are in 2016 and Apple has decided to make things easier even for developers to install a new iOS BETA version on an Apple device. Apple has released a new developer “Configuration Profile” that will allow the BETA seeds of the Apple Developer program to be installed on devices via over-the-air (OTA) even if the device doesn’t currently have a pre-release version installed.
If you are a member of the Apple Developer program, you will need to log into the Apple Developer website, head to the download tab and download/install the “Configuration Profile” directly to your iPad or iPhone.
Once you have that configuration profile installed on your iDevice, it will allow you to download the new iOS BETA version via OTA. To do this, head to your iDevice’s Settings->General->Software Update. This way, the developers will not lose so much time by manually downloading and installing a new iOS BETA version on their iDevices.
