N2 - We present the catalogue and properties of sources in AS2UDS, an870-$\mu$m continuum survey with the Atacama LargeMillimetre/sub-millimetre Array (ALMA) of 716 single-dish sub-millimetresources detected in the UKIDSS/UDS field by the SCUBA-2 Cosmology LegacySurvey. In our sensitive ALMA follow-up observations we detect 708sub-millimetre galaxies (SMGs) at $>$\,4.3$\sigma$ significanceacross the $\sim$\,1-degree diameter field. We combine our precise ALMApositions with the extensive multi-wavelength coverage in the UDS fieldto fit the spectral energy distributions of our SMGs to derive a medianredshift of $z_{\rm phot}=$\,2.61$\pm$0.09. This large sample reveals astatistically significant trend of increasing sub-millimetre flux withredshift suggestive of galaxy downsizing. 101 ALMA maps do not show a$>$\,4.3$\sigma$ SMG, but we demonstrate from stacking {\it Herschel}SPIRE observations at these positions, that the vast majority of theseblank maps correspond to real single-dish sub-millimetre sources. Wefurther show that these blank maps contain an excess of galaxies at$z_{\rm phot}=$\,1.5--4 compared to random fields, similar to theredshift range of the ALMA-detected SMGs. In addition, we combine X-rayand mid-infrared active galaxy nuclei activity (AGN) indicators to yielda likely range for the AGN fraction of 8--28\,\% in our sample. Finally,we compare the redshifts of this population of high-redshift, stronglystar-forming galaxies with the inferred formation redshifts of massive,passive galaxies being found out to $z\sim$\,2, finding reasonableagreement -- in support of an evolutionary connection between these twoclasses of massive galaxy.
