Build date expired??

I live the game terraria i have it on my pc and i thought why not have it with me on the go? Well now that i have an iPhone 7 the game screen says "Build date expired please update" what does this mean? When i go to the settings i cant press controls or anything like that. I hope you can fix this I really look forward to the game. ?
