The term "mora counting" has a specific technical meaning, based on the connection between duration and certain linguistic units (moras, syllables, stress feet). In a so-called syllable-timed language, the duration of an word best correlates with the number of syllables in the word. In a mora-timed language it correlates best with the number of moras. The difference between the two is evident only when there is a difference between the number of syllables in a word and the number of moras -- which means, you have to have long vowels or some reason to posit moraic coda consonants. Neither of these conditions holds in Swahili, so it is impossible to determine if the language is syllable-timed or mora-timed.
However: the claim for there being any "mora-counting" Bantu languages is dubious. The implication of mora-counting is that a 4-mora word has twice the duration of a 2-mora word and half the duration of an 8-mora word. Instead, Bantu languages tend reduce duration of long vowel preceding the penult or antepenult (sometimes resulting in actual phonological shortening). This is more like a stress-timed system (there is at most one stress, on the penult, so the last two syllables tend to be a length unit and the stuff before – regardless of the number of syllables – tends to be a length unit, which can stretchto very many syllables)
There is not very good evidence in Swahili for the mora, since there is no vowel length, and it does not have a mora-counting tone system. The evidence for vowel length in orthographic kondoo, njoo is not strong: vowel doubling in spelling is a way of indicating final stress. The alternative is to say that in some words the stress is final (or antepenult, e.g. barábara). This is in contrast with many (don't know about most) Bantu languages which do provide ample evidence for the concept of mora. There is some confusion out there about the status of "moraicity", since there are surface-contrastive syllabic nasals in Swahili, and these are frequently called "moraic nasals". But that is simply driven by a particular theory of syllables and syllabicity, where "syllabic" i.e. "being a syllable peak" is taken to be defined as "being moraic". If you don't insist on that equation (I don't), then there is no evidence for "moraic nasals". Ngunga and Hyman have a paper illustrating the problem, from Yao (a language with excellent evidence for the concept of mora).
