Single quote character in Swift -

trying add single quote ' character in code in swift, it's adding \' , api call.

my code is:

    let locationlat = string(format: "%f", (currentlocation?.coordinate.latitude)!)     let locationlong = string(format: "%f", (currentlocation?.coordinate.longitude)!)     let apilocation = "$filter=geo.distance(location,geographypoint" + "(" + locationlat + locationlong + ")) le 0.1" 

i need make apilocation variable like:

$filter=geo.distance(location, geography'point(lat, long)') le 0.5&searchmode=all&$count=true 

let me know thanks.

using escape character single quotes \' = ' , interpolation (\())for variables can achieve in 1 string.

let apilocation = "$filter=geo.distance(location, geography\'point(\(locationlat), \(locationlong))\' le 0.5&searchmode=all$count=true"
