So, you should use a layered architecture and you will not have those problems.

• service layer, it's the lowest layer reads the data from either web or db, or other services
• repository layer gets the data from service and process it, caching, etc
• usecase layer combines data from multiple repositories
• viewmodel layer gets the data from usecase and sends it to view

each service or repository handles one type of data "Users" for example

now, if you need to combine multiple types of data, like Users and Companies let's say, you need a Usecase layer which will combine all the data

on your viewmodel you only use the usecase layer

One important note, passed objects change between layers, so on service layer you have UserDto (coming from webservice), and UserEntity (coming from DB), the repo will transform those in UserResponse, which you don't know if it's db or webservice and even more the UseCase will transform UserResponse and CompanyReponse into a User object which will be passed to ViewModel and will contain all data required there.

Also, until you get to the viewmodel layer you should not need SwiftUI, if you need it, you are doing something wrong, use Swift Combine to handle data.

In the section titled Compatibility Version Numbers at Runtime within https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/VersionInformation.html the context & meaning is fairly clear that the Xcode linker links against only one version (and that it must be the older version if the framework is dynamically linked). I.e., all of the determiners are singular: no linking 2 or more versions into the same app. So it seems that you have exactly 2 choices:

• upgrade Framework A to utilize RxSwift 2.0
• forego using RxSwift 1.0 in your app so as to use RxSwift 1.0 in your app (throughout your app, both Framework A and your app-domain)

The desired choice of linking in both an RxSwift 1.0 identifier and an RxSwift 2.0 identifier for the same identifier is not possible with the Xcode linker, the desired choice (linking in 2 different versions of RxSwift into the same app executable) is actually a nonexistent choice—hence not an option after all.

The Problem now solved.

It is appear that one of the library we are using, have dependency on new 'Algorithms' Swift ( https://github.com/apple/swift-algorithms ) . Therefore we can resolve by doing 2 way

• adding the Algorithms Swift dependency to the projects
• revert the library into before using Algorithms Swift

Thanks.

Here's an example for continuously clicking that element.

The main difference is that Kotlin code compiled for iOS brings along the Kotlin/Native runtime which establishes the Kotlin/Native memory model that aims for safe concurrency and immutability of global objects, and also provides its own garbage collector for Kotlin objects.

Otherwise, code compiled with Kotlin/Native indeed has two-way interoperability with Swift, as normally the Kotlin binary that you use on iOS is an Objective-C framework that you can import in one project with Swift.

DispatchSource is a class, i.e. a reference type. In your second example the dispatch source is stored in a local variable of the function. As soon as the function returns, no reference exists to the dispatch source, so that it is canceled and deallocated.

You need to store the dispatch source somewhere where it lives as long as the program runs, e.g. in a global variable:

The simplest & fastest is to use value-type model.

Here is a simple demo. Tested & worked with Xcode 12 / iOS 14

xcode11

-build setting

-user-defined

-add setting: USE_SWIFT_RESPONSE_FILE (by pressing + sign on top)

-setValue:NO

Here you are!
