iOS why i am not able to create child directories within parent directory within the Documents directory?

i'm facing issues while creating child directories within the Documents dir

i get Documents path with NSHomeDirectory() return: /var/mobile/Containers/Data/Application/3CE312DC-8A49-4EF6-83D1-C205F2EF1C0B

and create dir with

std::filesystem::create_directory((homePath+"/Documents/assets").c_str()) return success

std::filesystem::create_directory((homePath+"/Documents/assets/images").c_str()) return permission denied

and with NSFileManager return the same

void iOSCreateDirectory(const char*path){
 NSString*directory=[NSString stringWithUTF8String:path];
 NSError*err;
 NSFileManager*fm=[NSFileManager defaultManager];
 if(![fm fileExistsAtPath:directory]){
  if(![fm createDirectoryAtPath:directory withIntermediateDirectories:YES attributes:nil error:&err]){
   NSLog(@"CreateDirectory Error %@ %@", directory, err);
  }
 }
}

iOSCreateDirectory((homePath+"/Documents/assets").c_str()) return success

iOSCreateDirectory((homePath+"/Documents/assets/images").c_str()) return Code=13 "permission denied"

Error Code=513 "You don't have permission to save the file "images" in the folder "assets"."

am i missing something here?

Solved

the problem is the assets directory was created with std::filesystem::create_directory()

Thanks

I suspect it may be a formatting issue with your path construction. This works:

NSFileManager *fm = [NSFileManager defaultManager];
NSURL *appDirURL = [[fm URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
NSError *error;
NSURL *newDirectoryURL = [[appDirURL URLByAppendingPathComponent:@"assets"] URLByAppendingPathComponent:@"images"];
if (![fm createDirectoryAtURL:newDirectoryURL withIntermediateDirectories:YES attributes:nil error:&error]) {
    NSLog(@"Error: %@", [error localizedDescription]);
}
