According to Bloomberg's latest survey of economists (7 to 14 September)

As mentioned in last month's survey results, Q4 2019 definitely looks to be the more likely timing for liftoff by the SNB and respondents this time around converge to that result. Not really anything to move markets but continues to highlight that the market only expects the SNB to move after the ECB does "through the summer of 2019".

And with the Swiss franc causing a problem for the SNB in the wake of an improving economy, it could yet push back the timeline of a rate hike if this persists into the new year.

Do be reminded that the SNB will be meeting this Thursday and with the swissie's recent strength, it could prompt verbal intervention by the central bank.
