The `MigrationResult` indicates the result of a migration.
The `MigrationResult` can be treated as a boolean:
```
CoreStore.upgradeSQLiteStoreIfNeeded { transaction in
// ...
let result = transaction.commit()
if result {
// succeeded
}
else {
// failed
}
}
```
or as an `enum`, where the resulting associated object can also be inspected:
```
CoreStore.beginAsynchronous { transaction in
// ...
let result = transaction.commit()
CoreStore.upgradeStorageIfNeeded(SQLiteStorage(fileName: "data.sqlite")) { (result) in
switch result {
case .success(let hasChanges):
// hasChanges indicates if there were changes or not
case .success(let migrationSteps):
// ...
case .failure(let error):
// error is a CoreStoreError enum value
// ...
}
}
```
