converting ios 3rd parth APIS to 64bit architecture

i am new in ios development and now days working on an app that has been designed in 32 bit architecture with lots of 3rd party apis and cocopods usage in it.

As apple has decided to move all the apps to 64-bit architecture, i'm unable to figure out if there's any api in my code that's not following the rules and is still in 32bit architecture.

is there any way to check that and to convert them for 64bit architecture support.???
