I do Xamarin (Microsoft's iOS / Android framework) and the listings often throw in Swift / Java / Kotlin. Sometime's they'll throw in React Native and Flutter even if they don't use them. The Xamarin world isn't huge and I guess they just want to try to grab the attention of as many hybrid mobile devs as possible.
