Nice tool by Paul Hudson: Control Room is a macOS app that lets you control the simulators for iOS, tvOS, and watchOS – their UI appearance, status bar configuration, and more. It wraps Apple’s own simctl command-line tool, so you’ll need Xcode installed. Some features, such as sending example push notifications or move between light […]

Open your React Native’s Xcode project file from the CLI with xed
For a long time I always used the open command to open the Xcode project file contained inside React Native Projects. bramus in ~/repos/projects/react-native/example $ open ios/Example.xcodeproj It wasn’t until I recently started a new React Native project that react-native init afterwards informed me to use xed instead. The xed tool launches the Xcode application […]
Upgrading from React Native 0.53.x to 0.57.4 (and to Xcode 10 and Gradle 4 along with that), a journey
Back in November, after 6 months of working on other projects, I picked up development for the EV-Point Mobile App again. The app is built using React Native and is available on both iOS and Android. As Xcode got a new major release (from Xcode 9 to Xcode 10) since my last time working on […]
Fixing iTunes Connect “ERROR ITMS-90717” with ImageMagick
When recently publishing an app to the App Store (or at least trying to get it published back then), I couldn’t upload the app via the Application Loader. I got back ERROR ITMS-90717 “Invalid App Store Icon. The App Store Icon in the asset catalog in ‘Your.app’ can’t be transparent nor contain an alpha channel.” […]
XCode 9.0: Fixing a Slow/Unresponsive iOS Simulator
Whilst initially implementing react-native-maps into a project I noticed that the iOS Simulator didn’t quite like it. Whenever the Mapview was visible on the screen, the Simulator was maxing out on something. Turns out the OpenGLES.framework that comes with XCode 9.0 – and not react-native-maps itself – is the culprit. That version is buggy and […]
ionic/cordova emulate vs. Xcode 7
After the App Store automatically updated Xcode to version 7 (without me actually wanting this for now, but hey …) running ionic emulate ios -c -l would not do much anymore: The app would launch but get stuck at the loading screen No console.log() calls would be logged Fixing it manually To fix this, update […]
XCode: Quick Look for UIViews
Xcode 5.0 introduced an interesting new feature: Quick Look for variables. Basically, it lets you inspect variables and their contents in a graphical way. Xcode 5.1 improves the feature even further with the addition of debugQuickLookObject. This method allows you to provide quick look content for any of your own classes. A bit like debugDescription […]

iPhone Simulator: The simulated application quit
Fresh OS X install, fresh XCode install, and starting the iPhone Simulator (without launching any custom app) quits at start-up and spits out a “The simulated application quit” error dialog. Turns out the Asepsis feature from TotalFinder (the feature which prevents the creation of .DS_Store files) is the culprit. Disable that feature and all will […]
