All the options I mentioned -- swift-lambdatron, Goby, and RoboVM can be
used to make apps to submit to the app store. None require jail breaking.
Goby and RoboVM have been used for apps that were accepted.
The compiled form of each app is a bonified Objective-C style LLVM binary.
The ClojureSwift
Also worth mentioning is Gal Dolber's project
https://github.com/galdolber/clojure-objc. It's a modified version of the
Clojure compiler which outputs Java source instead of bytecode, and then
uses Google's J2Objc project. It's pretty neat - he has two iOS apps live
which were totally written in

Swift seems to support Tail Call Optimization, according to this thread:

What I haven't been able to figure out is if we actually get FTL with

Thanks David! Targeting ClojureScript to iOS just got an order of magnitude
easier for me.
I want to say that Colin Fleming (Cursive) has been extremely helpful in
helping me sort out how to achieve this.

Very interesting project - CLJS may be a viable option for iOS app
development, which is pretty exciting stuff.
One thing I dimly remember from somewhere (HN, maybe) was that
JavaScriptCore apps wouldn't get JIT'ed, because iOS apps have no access to

Thanks!

GC means pauses. Swift doesn't have proper GC, only ref counting because of
that. GC pauses in UI are bad.
I like idea of Clojure on some new fancy high performance language like Go
or Swift.

While Gal's approach of ditching IB is fine, I still use it, but bind UI

power at your disposal on the ClojureScript side of the JavaScriptCore bridge:
With atom watchers you can react to UI state changes, feed them

Maybe ClojureSwift does have potential, even with respect to *performance* as
well: There's decent speculative chatter [1] about Swift’s safety enabling
aggressive optimizations that can't be performed in unsafe languages like
Objective-C, with Swift outperforming on RC4 and other benchmarks.
The recent release of Swift made me revisit Clojure on LLVM. This post from
2010 https://groups.google.com/d/msg/clojure/KrwtTsdYZ8I/Qf8PSMeoZCUJ
suggests it's a very difficult task.
Swift would make this job easier? As with ClojureScript, generate Swift
code / provide interop and Clojurian's
I'm starting to feel like a broken record, but here we go.
Some things to think about:
1) Why do you want this? The JVM GC and JIT are some of the fastest (if not
the fastest) on the planet, so performance will never be a good reason to
do this.
2) Do you want something like eval? As far as I
I have been experimenting writing an iOS app using ClojureScript embedded in
JavaScriptCore, where the ClojureScript essentially implements the logic of my
view controllers which drive native UI.
So far, this approach seems like a reasonable one to “writing iOS apps using
Clojure.”

@Timothy, you mention speed a lot, but I'm not sure where in the OP it
mentioned wanting to do this for speed at all. I think the intention is to
be able to Clojure on a different platform, is all.

I wasn't really pointing at performance with my post. More about native app
development, for OSX we have Clojure on the JVM which is fine. I don't see
Apple allowing Java on iOS anytime though.
Thanks for the replies so far, this was purely food for thought.

I wouldn't pass judgement on Swift too soon. Eval works just fine in the
REPL and it appears the language supports hot code loads out of the box.
Swift also has real support for final fields via 'let'. I personally think
a ClojureSwift could be quite interesting :)

Does Swift have any static types to harvest? :)
