SwiftWeather Forecast

Hi Jake Lin,

Like we discussed a while back I added a forecast feature to the app. In a next step I will do the forecast widget feature. I hope you like it :) And also: are you updating the .md file with new images or should I do that? Here is a picture of how the app looks with the forecast:

kind regards,

Marc
