Abstract: A latch and perf assembly for completion of a wellbore comprises a setting tool with an explosive charge and a wireline connector, a run-in tool installed on the setting tool, a latch installed on the run-in tool and adapted to assume a retracted state during run-in of the assembly and an expanded state when the latch arrives at a predetermined depth in the wellbore and a seal inside the latch adapted to seal against hydraulic pressure applied from surface. The assembly is adapted to be run into the wellbore attached to a wireline, and at least a predetermined part of the seal is adapted to dissolve after fracking of the wellbore.
