The general idea is that lists return results directly, and generators use the
output of a list to feed into another module (like a UNIX pipe).  So generators
essentially are the intended way to combine modules in one query like this. 
The problem is for some reason list= is also used/necessary in this case.  See

I notice this does not use indexpageids.  So you're only getting it in the
correct order if whatever iOS JSON parser you're using preserves order in
hashes/associative arrays (possible, but not certain).  

See
https://en.m.wikipedia.org/w/api.php?action=query&format=jsonfm&generator=prefixsearch&gpslimit=24&gpsnamespace=0&gpssearch=fish&list=prefixsearch&pilimit=24&piprop=thumbnail&pithumbsize=144&ppprop=wikibase_item&prop=pageprops|pageimages&pslimit=24&pssearch=fish&indexpageids
for a version with indexpageids with a clear array of results.

Also, it's using generator=prefixsearch not generator=search (which comment #0
mentions).
