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 […]

Interacting with the iOS Simulator from the Command Line using simctl

Wasn’t aware of this, but turns out one can control (and interact with) the iOS Simulator straight from the command line. There’s no need to install anything new though. The tool we’re going to be using is already on our Mac, hiding inside the xcrun command, which gets installed with Xcode. It’s called simctl. Here’s […]

FBSimulatorControl – A Mac OS X library for managing and manipulating iOS Simulators

Just launched by Facebook: FBSimulatorControl, A Mac OS X library for managing, booting and interacting with multiple iOS Simulators simultaneously. FBSimulatorControl works by linking with the private DVTFoundation, CoreSimulator and DVTiPhoneSimulatorRemoteClient frameworks that are present inside the Xcode bundle. Doing this allows FBSimulatorControl to talk directly to the same APIs that Xcode and simctl do. […]

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 […]

Xcode iPhone Simulator location

I keep on forgetting the location of iPhone Simulator.app (I know, you can access it from within XCode, but that’s not always running when developing a website). Placing it here not to forget it anymore (and to find it back via Google): XCODE 4.3 and XCODE 5:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app XCODE 4/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app Pro-tip, place a link […]
