swift - Realm crashing sometimes on initialization -


i received reports app-store realm crashes on initialization, without details. hope (from realm team?) can see problem.

here how create instance:

 func loadrealm() -> realm {          if let realm = self.realm {             return realm         }          if let _ = nsclassfromstring("xctest"){             realm =  try! realm(configuration: realm.configuration(fileurl: nil, inmemoryidentifier: "test", syncconfiguration: nil, encryptionkey: nil, readonly: false, schemaversion: currentschemaversion, migrationblock: nil, deleterealmifmigrationneeded: true, objecttypes: nil))         } else {             realm =  try! realm(configuration: realm.configuration(encryptionkey: nil, readonly: false, schemaversion: currentschemaversion, migrationblock: nil, deleterealmifmigrationneeded: true, objecttypes: nil))         }         return realm!     }

it happpens in line executed when not test. error "swift_unexpectederror".

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
