Coding in Swift feels slower than Objective-C. I’m sure that’s partly due to not yet having the same level of mastery of Swift, that I felt I had with Objective-C. However I came across this quote, which reflects my experience:
Dynamically typed languages give fast positive feedback, but slow negative feedback, whereas statically typed languages do the reverse.
A common error I saw causing crashes in released apps - mine and others (hello Xcode) - was inserting a
nil into an
NSArray. Swift’s type-system should entirely eliminate this source of failure.
Xcode lends a hand
The other thing I’ve noticed is that Xcode appears to be providing more helpful completions with Swift than Objective-C. With Swift Xcode feels like a welcomed partner as I write my Swift code; helping me with function signatures and providing closure bodies. I didn’t feel the same way about Xcode and Objective-C.
That said Apple still has a way to go on with Xcode and Swift:
