After updating iOS, all applications using the framework stopped running on the device, but they run on the simulator

I had the same issue with realm, it would work on the simulator but crash instantly on the actual devices. It seems when updating to iOS 13.3.1 Apple changed the behaviour of free apple developer accounts, no longer allowing them to use embedded frameworks.

The solution is to remove the use_frameworks! in your Podfile and replace it with use_modular_headers!

e.g.

target 'your_project_name' do
    use_modular_headers!
    pod 'RealmSwift'
end

This will include them as static libraries instead. I stumbled upon the solution in this GitHub issue: https://github.com/Alamofire/Alamofire/issues/3051

Removing use_frameworks. It will break your Firebase pods. For projects that utilize Firebase pods, your solutions consist of the following..

Downgrade your iOS device
Create & pay for an Apple Developer Program
Use the simulator and wait for future iOS updates that will hopefully once again allow free dev accounts to use Frameworks again..

This is very often issue which needs to be eliminated by official sources
