How to connect forerunner 945 to Zwift apps in IOS

Dear all,

I’m a newbie here. I have read about broadcasting your heart rate from your Garmin watch and it will be connected to Zwift. I’ve been trying to do it but zwift apps in my iphone keep on searching for paired devices.

Is there any other way to connect my Garmin forerunner 945 to zwift apps?

I really want to use zwift for my treadmill training

The Garmin broadcast the HR in ANT+, so your best solution is to get a dual band HRM link the Wahoo Tickr.
