spm | Brand new static package manager

This is my first post here and I am not that experienced, so please excuse my ignorance.

I am building a Monte Carlo simulation in C++ for my PhD and I need help in optimizing its computational time and performance. I have a 3d cube repeated in each coordinate as a simulation volume and inside every cube magnetic particles are generated in clusters. Then, in the central cube a loop of protons are created and move and at each step calculate the total magnetic field from all the particles (among other things) that they feel.

At this moment I define everything inside the main function and because I need the position of the particles for my calculations (I calculate the distance between the particles during their placement and also during the proton movement), I store them in dynamic arrays. I haven't used any class or function,yet. This makes my simulations really slow because I have to use eventually millions of particles and thousands of protons. Even with hundreds it needs days. Also I use a lot of for and while loops and reading/writing to .dat files.

I really need your help. I have spent weeks trying to optimize my code and my project is behind schedule. Do you have any suggestion? I need the arrays to store the position of the particles .Do you think classes or functions would be more efficient? Any advice in general is helpful. Sorry if that was too long but I am desperate...

Ok, I edited my original post and I share my full script. I hope this will give you some insight regarding my simulation. Thank you.

Additionally I add the two input files

I'm trying to add SPM support for my library. I need to define unsafeFlags for one of my library's targets (In order to import Swift code into Objective-C++):

I am working at Aliexpress automation with selenium and python, now stuck here, the problem is I am not finding any selector for the order quantity button, to increase the quantity according to the user choice, as incircled below in the image. I have tried class name but didn't work, if anyone knows the solution plz comment. link to the page is given: https://www.aliexpress.com/item/1005002611164689.html?spm=a2g0o.productlist.0.0.2fec7741zQOW1u&algo_pvid=null&algo_expid=null&btsid=0b0a555d16226644016931040e3512&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ tried code:

Overview

I'm porting an C++ / ObjC++ library to Swift Package Manager. The library targets common Apple platforms (iOS, macOS). Currently, the library can be built using xcodebuild and a static library target.

Question

Since the library contains C++ <> ObjC bridging code, it has one file compiled with the flag -fno-objc-arc. All of the other files are compiled with ARC. Is it possible to pass a flag telling SPM to also compile that file without ARC?

i am using this SDK https://github.com/apollographql/apollo-ios

and i cannot generate API.Swift File in My project

my schema.json file is propper format.

and i am using this code to run Generate API.Swift File

I have a package in SPM and I am dealing with file system. The problem I am facing now is my test case fails when I try getting the file like json file. here is my code and my test case.

Mt test

When trying to link to a system-installed library through Swift Package Manager, specifying it under pkgConfig, it says that the installed package wasn't found in the pkg-config search path. It suggests finding the .pc file that comes with the module but there isn't one.

How do I go about linking the library with SPM?

For a bit of background information: this app is supposed to load a map api and create a workout form linked to a location selected on the map by clicking. Once the map is clicked, a form is loaded to fill out info about that workout and then it's saved to the #workout variable.

Problem: I'm trying to save the #workout variable to local storage to then load all the workouts from storage whenever the page is reloaded.

I'm trying to run the _getLocalStorage() function in the constructor to load items from the local storage when the page loads, but I keep getting this TypeError code:

Swift Package Manager can be a convenient way to build swift projects, and, if you (remove the absolute toolchain @rpath it adds to your binary), you can even distribute its builds.

But SPM doesn't seem to produce .dSYM debug symbol packages, so how can you symbolicate the crash reports?

Is there a better way than using swift package generate-xcodeproj and then getting Xcode to create the build and dSYMs, effectively reducing SPM to .xcodeproj shorthand?
