Core Data Giving Error

hope this fix your issue The problem here is that your accessor and your ivar have the same name. That's where the underbar ivar convention comes from. Here, you're not using the accessor to access your property, you're using the backing variable directly, so it never gets initialize. Instead, make sure you always go through your accessor methods and you won't have a problem. So, rewrite the offending method (and any others that use the managedContextObject property with something like the following:
code :
- (void)viewWillAppear:(BOOL)animated
  [super viewWillAppear:animated]; // it's good practice to call the super methods, even if you're fairly certain they do nothing

  // Get a reference to the managed object context *through* the accessor
  NSManagedObjectContext* context = [self managedObjectContext];

  // From now on, we only use this reference in this method
  NSFetchRequest = [[NSFetchRequest alloc] init];
  NSEntityDescription* entity = [NSEntityDescription entityForName:@"Remind" inManagedObjectContext:context]; // <- use the local reference we got through the accessor
  [request setEntity:entity];
  NSError* error = nil;
  NSArray* array = [context executeFetchRequest:request error:&error];
  if( !array ) {
    // Do something with the error
    NSLog(@"Error Fetching: %@", error);
  [self setDesitnationsArray:[array mutableCopy]];
  [destinationsTableView reloadData];

.NET Core - Trying to add a repository to my API controller, but when I do every controller method returns a 500 error

wish helps you Short Answer
I'm trying to declare a repository in the constructor. I successfully declare it, but every API method I try to call in that controller returns a 500 error. When I remove the constructor/repository variable, I have no issues.
code :
public interface ITestRepository { }

public class TestRepository : ITestRepository { }
public class TestRepository : ITestRepository
    public TestRepository(object someObject)

public void ConfigureServices(IServiceCollection services)

        .AddDbContext<TestDbContext>(); // register a service

    services.AddScoped<ITestRepository, TestRepository>();
public class TestRepository : ITestRepository
    // pass the registered service to the ctor
    public TestRepository(TestDbContext testDbContext)

will help you Nuget has a status page which should tell you if it's nuget.org having issues: https://status.nuget.org/.
The HTTP request to 'GET https://api.nuget.org/v3-flatcontainer/microsoft.build.runtime/15.3.409/microsoft.build.runtime.15.3.409.nupkg' has timed out after 100000ms. suggestes that the issues are indeed network related as @babak-naffas has already suggested.

this one helps. I don't think you can use one class with multiple table in EF. Maybe it's the source of your error ? Try to create a parent class and one child by table :

I need help creating a scoring system, but it keeps giving me an error, the commented out integers are the parts giving

To fix this issue I found an RPS game and wanted to improve on it by creating a scoring system but the //int compwin = compwin + 1; keeps giving me errors. I am still fairly new to coding in C++ and have no clue where the problem is standing so thanks for helping in advance. Also this code was taken from somewhere this is not my code but I wanted to try and improve on it. , This
code :
int compwin = compwin + 1;
int compwin = 1;   // declares compwin and initializes it with 1
int compwin = 2;   // compiler error, because compwin is already declared
int compwin = 1;   // declare and initialize
compwin = 2;       // assign
else if (choice != 1 || 2 || 3 || 4) // Debug
else if (choice != 1 && choice != 2 && choice != 3 && choice != 4)
