I am currently an Android developer and I am taking this course to learn iOS development! I have only been developing for Android for a long time, so I was worried about whether I would be able to learn another language well, but as I listened to the Swift course, I found that it is very similar to Kotlin, so I am following the course relatively easily. The explanations are really good, and it is very useful because it does not just skim through the material, but also points out parts that can be used in actual development! I think I will be able to make an iOS app after listening to the whole course. Thank you~!
