I am trying to use this function github.com/Qiskit/qiskit-terra/blob/master/qiskit/transpiler/passes/routing/basic_swap.py and it take a DAG as input. The output is also a DAG, so I am trying to convert it back to usual QuantumCircuit
What is DAG circuit? How can I translate a DAG circuit to a QuantumCircuit?

You can use the
qiskit.convertersmodule which includes (among others):
qiskit.converters.circuit_to_dag(): qiskit.org/documentation/stubs/qiskit.converters.circuit_to_dag.html?highlight=dag#qiskit.converters.circuit_to_dag
qiskit.converters.dag_to_circuit(): qiskit.org/documentation/stubs/qiskit.converters.dag_to_circuit.html?highlight=dag#qiskit.converters.dag_to_circuitAnd if you are trying to perform the basic_swap on a circuit, you can also do:
swap_pass = BasicSwap(coupling_map) swapped_circuit = swap_pass(circuit)
