As someone who writes Kotlin and Swift on a regular basis, the Java bits that leak through to Kotlin are quite frustrating at times. If you picked up the language without a feel for Java’s quirks (as I did), Kotlin feels somewhat finicky and temperamental compared to Swift. In contrast, Swift has done an excellent job of making a real clean break from its Obj-C predecessor, despite sporting full Obj-C interop. It has for most practical purposes none of Obj-C’s quirks for pure Swift code, which is great. I frequently find myself wishing that Kotlin shared Swift’s level of independence from its predecessor, or that I could just use Swift instead. While Kotlin isn’t a bad language, its ties to Java leave me less than enamored.
