How to load a JNI .dylib file with a dependency without getting an UnsatifiedLinkError?

QUESTION

Swift class, method and property restrictions

Asked 2018-Nov-12 at 01:42

I'm searching for a working compromise between readability / usability and performance improvements through code restrictions.

According to this question and the linked Apple document it seems to be very important to use code restrictions as often as possible.

On the other hand, I have never seen an example where all code restrictions are implemented and I would never try to code like this:

The linked answer mis-states the linked blog post. If you're using Whole Module Optimization (which you should always be using in Release mode), you generally do not need to proactively add final or private for performance reasons. The compiler will figure out when they can be inserted. You should use final and private to express your intent to other programmers (and yourself), not the optimizer.

However, if Whole Module Optimization is enabled, all of the module is compiled together at the same time. This allows the compiler to make inferences about the entire module together and infer final on declarations with internal if there are no visible overrides.

QUESTION

How to load a JNI .dylib file with a dependency without getting an UnsatifiedLinkError?

Asked 2018-Nov-05 at 13:37

Goal: Link Java to Swift

Problem: I get an UnsatisfiedLinkError when trying to load a JNI .dylib file that is linked with a Swift .dylib file when calling System#loadLibrary(String).

Expected Behavior: The dependency of the Java .dylib would be automatically loaded or the call to System.loadLibrary("SwiftCode") would load the dependency (the only solution I could come up with).

Note: I am combining this github tutorial and this Medium article to create my JNI .dylib file and this tutorial to create my Swift .dylib file.

macOS ld builds a library dependency's path into the binary. The loader loading libSwiftHelloWorld.dylib will only find libSwiftCode.dylib if the latter is in the current directory. Loading the dependency in Java doesn't work because for the loader it's a different library.

You can change the built-in path for libSwiftCode.dylib with the -install_name argument (i.e. swiftc ... -Xlinker -install_name -Xlinker ). If you rebuild libSwiftHelloWorld.dylib afterwards it will reference the path that you gave.

QUESTION

Link model object to existing database table in Vapor

Asked 2017-Mar-13 at 08:53

I have a database with some complex relationships mapped and populated with a large amount of data. My requirement is that I need to use this database with Swift-Vapor server.

So that I created a model object (with Fluent framework constructs) similar to the database schema, in order to handle data flows between the vapor server and db.

When it comes the time to link database table(users table) with the model(User model), I found this method, which should implement inside the model class.

Got a solution while discussing this issue in Slack community, tried out and working fine.

Solution: In the model class (say User), the prepare method can be left unimplemented, like
