Cordova app hanging during startup on iOS 10
OK, I found the problem and the solution thanks to this post:
It seems that iOS 10 requires additional entries in the Content-Security-Policy meta tag, namely gap: and file:. After adding these, my Content-Security-Policy looks like this:
<meta http-equiv="Content-Security-Policy" content="default-src * gap: file:; style-src 'self' 'unsafe-inline'; img-src 'self' data:; script-src * 'unsafe-inline' 'unsafe-eval'">And the app starts up and works fine on iOS 10.
Hope this helps others.
I had the same problem during startup, and even if I did do a double tap on the home button and back to the app, cordova's file system wouldn't write to the device.
I tried a lot of things, but finally fixed it by adding
child-src * gap://readyto the Content-Security-Policy tag
