handling realm.io errors on startup (lazy way to handle migration changes, missing encryption key, etc)

gistfile1.swift

// this is the first call to defaultRealm() (ie: it lives in application:didFinishLaunchingWithOptions)
// see: SwiftTryCatch https://github.com/williamFalcon/SwiftTryCatch for a wrapper around ObjectiveC exceptions.

            SwiftTryCatch.try({
                RLMRealm.defaultRealm()
            }, catch: { exception in
                log.error("realm exception: \(exception.description). Will remove local database.")

                NSFileManager.defaultManager().removeItemAtPath(RLMRealm.defaultRealmPath()!, error: nil)
                
                SwiftTryCatch.try({
                    RLMRealm.defaultRealm()
                    }, catch: { exception in
                        log.error("realm exception on startup. Still not resolved.")
                        // TODO: analytics/log this to server
                    }, finally: {
                })
            }, finally: {
            })

ok, @simjp showed me this is a terrible idea.

This project has about it a whiff of the quiet, almost understated elegance of the La Brea tar pits. I like it.
