iOS Today Extension keeps crashing on iPhone, not in simulator - ios

Question

I'm trying to build an iOS Today Extension that shows three images with some text. In the simulator it runs fine, but when I run it on my iPhone, it flashes three times and then displays Unable to Load. What am I doing wrong?

The only error I get is that the Extension is Terminated due to Memory Error.

Answer 1

Extensions have much lower memory limits than normal apps. You'll have to investigate why you extension is using so much memory. Perhaps there's a leak.
