App runs perfectly on simulators but not on physical devices [on iOS 13.3.1]

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

Are you added framework in project under `Build Phases` -> `Embed Frameworks`? and error can also occur if you are using framework in different version then one currently being used. — Kishan Bhatiya, Feb 01 '20 at 07:21
and if it is error of framework then why the new project can't run (it has no framework ) — Shivam Parmar, Feb 01 '20 at 07:28
already tried cleaning project , restart project , restart Mac, reinstall Xcode — Shivam Parmar, Feb 01 '20 at 07:30

@ AlbinMrngStar according to reference you share its problem because of account but I don't think its relatable in my case because I try a new blank project with same account and it work .... — Shivam Parmar, Feb 03 '20 at 11:07
This might be helpful: https://stackoverflow.com/a/46759183/309046 If this didn't work share Podfile and Build Phase screenshot (Link Binary with Libraries and Embed Pods Framework). — Satish, Feb 03 '20 at 11:32
Have a look at this issue on [Alamofire Github](https://github.com/Alamofire/Alamofire/issues/3051) which has been raised. — chirag90, Feb 03 '20 at 13:49
You say that the app just shows a blank screen when you run it on a device with iOS 13. What does it show when you run it on a iOS 12 device? — EarlGrey, Feb 03 '20 at 21:30

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

This is working for every user of Alamofire framework so it must work for you unless you are using other frameworks like SQLite.swift. – Shebuka Feb 04 '20 at 11:05
after this implementation i got Could not build objective-c module error in all pods how can i solve this . ? – Virani Vivek Apr 15 '20 at 06:40
You issue is so generic there is no way we can help you. Post a new question with detailed explanation of your setup. – Shebuka Apr 15 '20 at 20:39

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.

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

Reference and solution here: Library not loaded: @rpath/FBLPromises.framework/FBLPromises iOS 13.3.1
