Should I install or just use virtualbox ?

Hello folks,

Got: i9-7900x, mobo with chipset x299, graphics - gtx 1080, 16gb ram. Should i bother doing clean install on ssd/hdd or just emulate it using vmware/vbox? I want to learn some app dev with swift for ios devices and using osx seems to be the best way to go. As u can see i've got quite powerfull HW so i'm not sure if it is worth installing it instead of just emulating.
