Top Mobiles app framework, cross vs native, how choose ?

Native frameworks like android studio and xcode from apple provide native ui/ux , development speed is slow, maintenance cost high, performance very high, programming languages objective C and Swift on apple, Java and kotlin on android, this frameworks are very mature and very few bugs, Ui native user experience look like native platform, the downsize is the speed/cost of development, because we have to create the app twice one for android and one for iOS, that increase the cost of product and maintenance.
