I'm having issues with compiling and linking. Randomly, either the compiler or the linker fails with error reports similar to this:

I'm thinking this is either a problem with the RAM or my computer is overheating.
Thoughts?

How can playground or any app exec an swift code or show an update live of view that we are make?
I want to know this because i want to build app that help you to build views without coding..so i want the same Features that used on swift playground and xcode that exec swift code and show update live of view.

TimeoutError: Timed out waiting for connection to DTServiceHub after 15.0 seconds.
I'm getting this error when trying to preview SwiftUI views. And I'm getting it for a brand new app with nothing else going on. I've tried the usual troubleshooting like Clean Build Folder.
Also having trouble getting the app to build on my Apple Watch. I'm wondering if this is a serious bug with Xcode 13.2.1 (13C100)

I am creating an app that uses firebase on Xcode. I installed the 64 bit version I read others recommended on the new M1 Macs and every time I open up my computer again, I get 15 errors of 'Redefinition of Firebase' in all files like the modulemap, object.h, dispatch.h, CFNetwork.h, AXFoundation.h as well as 'Could not build module 'CoreFoundation'
I am not sure what to do since I am new to the swift language and Xcode. I have not been using the workspace rather the project and it worked the first time I installed it. I also tried uninstalling and redoing the pod install, but to no avail.
I would like my code to work as I am just trying to make a way for others to sign in so I can build the rest of the app. Thanks!

I have been looking for objcopy as I need to rename some functions in a precompiled library. I installed the gnu binutils version (brew install binutils) .. this generates a file that the gnu binutils thinks is perfect. The Apple objdump throws up error messages.

I'm a university student and this is my first time coding anything. I was doing pretty good but now, for some reason, my xcode will only run the first .c file i made within the project, even if i have a different one selected. My screen is shown in this screenshot to make it make more sense.
https://imgur.com/a/yjNi9QA
The "Hello world" code is in the first "main.c" file on the left, but whenever i try to run q1d or q2a, it only runs Hello World, not the actual files.
Please help!!!!

Hey,
Ive been trying to run this app from GitHub. It successfully compiled but once it started launching the program only bounced in the dock and didn’t show anything. Here’s what Xcode says
Please help me fixing it. I really want to run this app.
Many thanks for your help in advance
Hey,
I'm not bad with computers but not a developer at all. I really want to use the app from this GitHub page.
The problem is that the creator hasn't published a release yet so I have to compile it myself. When I hit build in Xcode it immediately shows a number of errors. How can I fix them and get it to build?
Please excuse me very much for asking such a noob question but please help me guys. You would make somebody very happy.
Thanks very much for your help in advance!
When compiling my project for a physical device, Xcode does not reuse the build cache but instead recompiles every file. When compiling for a simulator target instead, Xcode properly uses the build cache, and incremental builds are lightning fast.
Is there a configuration I can check to enable incremental builds for physical devices, too?

I am using Xcode 13.1 and get the following Apple Mach-O Linker Error when building in Release mode only (project can be successfully built in Debug mode) :
ld: reference to symbol (which has not been assigned an address) __ZNSt3__113__vector_baseINS_12basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEEENS4_IS6_EEED2Ev in '__ZNSt3__16vectorINS_12basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEEENS4_IS6_EEED1Ev' from <my-path-placeholder>tmp.a(Tmp.o) for architecture arm64
This error only happens on newer versions of Xcode (13 and up).
Any ideas?

The project can run on simulator well but it can't run on the iOS devices. I got the error:

According to Increasing Performance by Reducing Dynamic Dispatch, addding 'final' keyword increase runtime performance by reducing dynamic dispatch.
I'm wondering if adding 'final' keyword will also improve compile time.
read such opinions in some articels, but not clear to me.
I tested it, and it seems to me 'final' not affect compile time.

HI!
I've compiled a command line utility written in plain C on macOS Monterey on macBook m1 pro. The compilation command is just following:
clang -std=gnu11 -Wall -o my_run_ht run_ht.c ht.c
It compiles fine but when I try running it, it is aborted with the following message:
dyld[8385]: dyld cache '/System/Library/dyld/dyld_shared_cache_arm64e' not loaded: syscall to map cache into shared region failed
dyld[8385]: Library not loaded: /usr/lib/libSystem.B.dylib
Referenced from: /Users/sasha/Src/my/ht/run_ht
Reason: tried: '/usr/lib/libSystem.B.dylib' (no such file), '/usr/local/lib/libSystem.B.dylib' (no such file)
What is more strange that I can compile and run other command line utilities. So I'm quite puzzled and have no idea what is the reason for that and how to fix it.
Could anybody please help me with this?
Thanks in advance.

Hello,
When trying to open a project written in approximately August in xcode 13.2.1 version, I get the error 'module compiled with swift 5.3.2 cannot be imported by the swift 5.5.2 compiler'. As you can see in the attachment, I get 127 errors when I run it with the 5.3.2 toolchain. How can I upgrade an existing project to version 5.5.2?
Thank you in advance for your help
Hi all,
my project is running fine on simulator and real device, but when I try to archive it for distribution the following error code appears.
Build input file cannot be found: '/Users/mauro/Library/Developer/Xcode/DerivedData/FlexoCalculator_mobile-acfisshphqrnvoennhvdkcvtplhc/Build/Intermediates.noindex/ArchiveIntermediates/FlexoCalculator_mobile/InstallationBuildProductsLocation/Applications/FlexoCalculator_mobile.app/FlexoCalculator_mobile'
I already cleaned build folder and derived data but issue is still there. I have no idea on where this error comes from and how to clean it.
Any help is appreciated.
Xcode 13.2.1 -
Swift 4 -
Project for iOS 10
This project was well compiled and distributed for years. Now, after upgrade to Monterey/Xcode 13, I'm not able to compile it anymore.
This error is not visible on logs, but is present on left panel only:
Consider a C++ method that retrieve struct of native typed arguments like enum class, sub-structs, std::string, int, etc...
I'd like to create a swift API that return the same struct but in swift variables
for example :
class ErrorMessage {
public:
int status;
std::string message;
};
class serverResponse {
public:
ErrorMessage error;
std::string str_value;
std::uint16_t int_val;
std::time_t last_seen;
EnumVal status;
};
serverResponse getServerResponse();
So I'd like to convert it to the swift equivalent struct with native members
open class serverResponseSwift : NSObject {
open class var error: ErrorMessage { get }
open var str_value: String { get }
open var int_val: UInt16 { get }
open var status: EnumVal { get }
};
I know that direct conversion is not yet possible so I need to use objective-C++ code as a mediator. So I've used a bridging header to include the converting method in objective-C++ which will look like this :
@interface Converter
- (serverResponseSwift) getServerStatusSwift;
@end
and the equivalent .mm file will implement the conversion function, but can I use the swift Class in objective-c in order to fill it up according to the CPP serverResponse ?
@implementation Converter
- (serverResponseSwift) getServerStatusSwift {
serverResponse x = getServerResponse();
/// How do I create serverResponseSwift out of serverResponse
}
Thanks !

How can I do parallel computing on CPU and GPU of M1max
In deed, I buy Mac m1max for the strong GPU to do quantitative finance, for which the speed is extremely important. Unfortunately, cuda is not compatible with Mac.
Show me how to do it, thx.
Are Accelerate(for CPU) and Metal(for GPU) can speed up any source by building like this:
Step 1: download source from github
Step 2: create a file named "site.cfg"in this souce file, and add content: [accelerate] libraries=Metal, Acelerate, vecLib
Step 3: Terminal: NPY_LAPACK_Order=accelerate python3 setup.py build
Step 4: pip3 install . or python3 setup.py install ? (I am not sure which method to apply)
2、how is the compatibility of such method? I need speed up numpy, pandas and even a open souce project, such as https://github.com/microsoft/qlib
3、just show me the code
4、when compiling C++, C source, a lot of errors were reported, which gcc and g++ to choose? the default gcc installed by brew is 4.2.1, which cannot work. and I even tried to download gcc from the offical website of ARM， still cannot work. give me a hint.
thx so much
urgent
