When developing in Swift, you will eventually need to interact with Objective-C APIs. Most of the time this is fine, and fairly straightforward to do using #selector. However, every once in a while you will need to invoke an Objective-C selector that you did not write (usually when the selector is part of the iOS or macOS SDK), does not have a unique signature, or is just pretty hard to figure out. This article put out by Big Nerd Ranch’s Mark Dalrymple is an excellent rundown of how to properly invoke Objective-C selectors from Swift. He even covers really hairy signatures that may be very difficult to come up with on your own at first glance. Big Nerd Ranch —[…]

I have been wanting the ability to merge two window’s collections of tabs in Google Chrome for some time now, because moving one tab a time from one window to another is tedious at best. I thought I’d need an extension for it, but it turns out that you can already do it in Chrome without any extra extension! I found this tip on the Google Chrome Product Forums, which tells how to do it: Merge two windows with multiple tabs Left-click the first tab in the window you want to merge. While holding the shift key, left-click the right most tab. All of tabs for the current window are now selected, so you can drag and drop them as as[…]
Somehow I don’t think I broadcasted this when it was available so now seems a good a time as any… My Core Bluetooth talk from Forward Swift 2016, “How Hot Is My Coffee? Sensors, Core Bluetooth and Swift!” has been up since last year, but thankfully it’s still up! Evan K. Stone: How Hot Is My Coffee? Sensors, Core Bluetooth and Swift! – Forward Swift 2016 Fitbit, Withings, Nest. The Internet of Things (IoT) innovation tidal wave has just begun, and those are just three of the more well-known players in the IoT and connected gadget landscape. It’s critical that iOS developers know how to connect and interact with BLE prototyping devices using the Core Bluetooth Framework provided by the[…]
Evidently this got posted to Realm’s website back in November, and I was not informed. Better late than never! Evan K. Stone – Saving Lives with iBeacons You’ve probably heard of iBeacons, but have you seen them up close or developed apps for them? iBeacon technology is a fun and easy way to start working with Bluetooth Low Energy devices. Cloud City Development has been working with Pop Up Labs at MIT to help develop a solution for educating health professionals about the Maker Movement and how it positively affects the medical community. With the help of iBeacons, health professionals have learned how to start creating their own devices and tools! In this talk from AltConf 2016, Evan will introduce[…]
React Navigation for React Native is “collaboration between people from Facebook, Exponent and the React community at large” as this comment on the project’s GitHub page indicates: React Navigation is born from the React Native community’s need for an extensible yet easy-to-use navigation solution. It replaces and improves upon several navigation libraries in the ecosystem, including Ex-Navigation, React Native’s Navigator and NavigationExperimental components. React Navigation can also be used across React and React Native projects allowing for a higher degree of shared code. Once stable, NavigationExperimental will be deprecated in favor of React Navigation. React Navigation is a collaboration between people from Facebook, Exponent and the React community at large. Also interesting is the revealing that React Native’s NavigationExperimental will[…]
I’m happy to announce that I recently updated Part Two of my Zero-to-BLE series on Core Bluetooth Post Updated for Swift at Cloud City Development Blog! It’s been updated for Swift 2, because when I wrote it, Swift 3 hadn’t officially been released and I honestly thought it would be published well in advance of the September 7 Apple Event. Zero to BLE on iOS – Part Two – Swift Edition Better late than never! Who knows? Maybe there will be a Swift 3 version in the future? For sure all my code samples will be in Swift 3… Hope you like it!
This weekend I finished and uploaded to the App Store a new version of an app I’ve been working on for the better part of this year. I uploaded version 1.0 in June and it took an extremely long time to get just one or two extra features into 1.1, and I was at long last able to get it submitted. With the average times for reviews being in the two-ish region, I’m hoping it will be up in the middle of this week. But then there comes the next project. This is one that I started in 2014, when I was desperate to get back into iOS development. I was stuck in a bizarre job situation in which the commute to[…]
