Short blog post: Converting ObjC exceptions to Swift errors

[mrh-is]

I combined this SO answer with this blog post so the block can return a generic something. Header & implementation here. Use like:

if let foo = try? ObjCException.try({
        return funcThatThrowsObjCException()
    }) {
    print(foo)
}

// or

do {
    let foo = try ObjCException.try(funcThatThrowsObjCException)
    print(foo)
} catch {
    print(error)
}
