Apple TF signature: Apple's official designated test application platform will not be dropped for 90 days..

TF signature is actually called TF listing, and its full name is testflight. It is actually Apple's official internal test distribution channel. We all know that iOS users only have the App Store official channel for downloading APPs, but testflight is also an official channel, but reliable TF signatures are used as internal test.
