As someone who rewrote his app in Objective C into Swift, I highly recommend it if you think Swift is rad (I do!) and enjoy substantially improving the quality of your code. That being said, I highly recommend against it if your primary goal is one of the following: - revenues - features - installs - bugfixes It will take you longer than expected to accomplish very little in terms of meaningful improvements which can be relayed to your customers.
