应用程序在模拟器上完美运行，但不能在物理设备上运行 [在 iOS 13.3.1 上]

Question

The app runs perfectly on every simulator but when I try to run it on a physical device , it shows the following error :-

I also tried to run it on various physical devices like iPhone 6 , iPhone 7 and iPhone 11. After that I came to a conclusion that the error is occurring on devices running on version of iOS 13.3.1 as App only runs successfully on iPhone 6 which is running on iOS 12.4.4

I also tried to run new project on same physical devices but it keeps showing me blank screen (on devices running on iOS 13.3.1) and if I install any framework in that new project then it's showing same error as shown in image.

I already tried:

• cleaning project
• restarting project
• restarting Mac
• reinstalling Xcode

Answer 1

In Alamofire issue tracker peoples are suggesting that doing these steps:

• remove/comment use_frameworks! in Podfile
• add use_modular_headers! in Podfile
• pod update
• pod install
• clean and run

solves the issue with using free Apple ID on iOS 13.3.X

Answer 2

This appears to be a known issue, and most people say it is a problem with using a non-paid Apple ID. Some kind of provisioning thing.

Answer 3

Apple blocked utilizing external frameworks on free accounts with 13.3.1 upgrade. Try downgrading to 13.3.
