ios - How to write this Objective-C Code into Swift -

-

i have method in objective-c i'm trying call in swift. 

    [testobjectloader loadobject:summarymetrics fromjsonfile:@"summarymetrics" withmapping:[mappingprovider summarymetricsmapping]];

enter image description here

this method loads json file, , when try use loadobject method, approach

testobjectloader.loadobject(summarymetrics, fromjsonfile:"summarymetrics", withmapping:mappingprovider.summarymetricsmapping()) enter image description here

but auto-complete not come up. have bridging file working, i'm not sure i'm doing wrong..

error message: testobjectloader.type not have member named loadobject

any appreciated.

in general, equivalent swift syntax be:

testobjectloader.loadobject(summarymetrics, fromjsonfile:"summarymetrics", withmapping:mappingprovider.summarymetricsmapping())
