I have an issue where my Ionic 2 app (just the default template with no code changes) does not respond on my lowly iPhone 4S and sometimes does not respond in the iOS simulator either. I’ve tried the default and the tutorial templates, the same happens with both.
Steps to reproduce (assuming ionic is already installed and an iPhone is attached):
ionic start TestApp --v2 cd TestApp ionic platform add ios ionic run ios --device (builds successfully but does not deploy first time around so run it again) ionic run ios --device
Wait for safequit to stop then notice the fade animation to the “Welcome To Ionic!” page.
Tap on the tabs - 9 times out of 10 the app is unresponsive. If it is responsive, quit the app (double tap home key and swipe off) then relaunch it from the home screen.
I’ve tried running the app from inside Xcode and can see that on the occasions when it is unresponsive, the CPU on the device is maxed and the memory utilisation grows rapidly until it crashes.
Has anyone else experienced this? Is there a work-around?
