The former Southampton and Everton striker was appointed on Tuesday.
Beattie, a former England international striker, played with current Swansea City boss Garry Monk at St Mary's and is now looking forward to working with him at the Liberty Stadium.
At least it seems that way from the Tweets he sent out yesterday. Beattie, clearly over the moon with the new job, sent out these two messages to fans and followers yesterday.

Hard work, diligence and total commitment to the cause. Helping this fine club progress under the leadership of an excellent young manager.— James Beattie (@1jamesbeattie) June 17, 2015
Beattie, as reported by the official Swansea website, has taken the role of first-team coach at the club where he will work alongside Alan Curtis and Kristian O'Leary.
The 37-year-old has previous coaching experience, having managed Accrington Stanley in League Two back in 2013-14. After 16 months in charge at the club he left in September 2014 by mutual consent.
Now he is back in the game Beattie, who has been doing punditry work for Sky recently, will be hoping to help Swansea push on after an excellent debut full campaign from Monk - with European football surely the aim.
