title: In Ios 14 Flutter App does not save in Debug mode
body: <p>recently I updated my iPhone version to IOS 14, but after updating to a newer software version my flutter app not save in debug mode.
  (As a simple word, I am run my flutter application on my ios device with a USB cable,
  but after removing the USB cable, my application automatically closes and not open again without connection in debug mode.
  this issue only arises in IOS 14.
  It works fine only if the connection is established in the device with Xcode.)</p>
  <p>this issue not arise in other IOS versions like IOS 13.</p>
